Many men and women have long bought into the idea that there are “male” and “female” brains, believing that explains just about every difference between the sexes. A new study 26_____ that belief, questioning whether brains really can be distinguished by gender.
In the study, Tel Aviv University researchers 27_____ for sex differences throughout the entire human brain. And what did they find? Not much. Rather than offer evidence for 28_____ brains as “male” or “female”, research shows that brains fall into a wide range, with most people falling right in the middle.
Daphna Joel, who led the study, said her research found that while there are some gender-based 29_____, many different types of brain can't always be distinguished by gender.
While the “average” male and “average” female brains were 30_____ different, you couldn't tell it by looking at individual brain scans. Only a small 31_____ of people had “all-male” or “all-female” characteristics.
Larry Cahill, an American neuroscientist (神经科学家), said the study is an important addition to a growing body of research questioning 32_____ beliefs about gender and brain function. But he cautioned against concluding from this study that all brains are the same, 33_____ of gender .
“There’s a mountain of evidence 34_____ the importance of sex influences at all levels of brain function, ” he told The Seattle Times.
If anything, he said, the study 35_____ that gender plays a very important role in the brain—“even when we are not clear exactly how”.

【A】 Any product that promises to protect your home deserves careful examination. So it isn’t surprising that you’ll find plenty of strong opinions about the potential vulnerabilities of popular home-security systems.
【B】The most likely type of burglary (入室盗窃) by far is the unsophisticated crime of opportunity, usually involving a broken window or some forced entry. According to the FBI, crimes like these accounted for roughly two-thirds of all household burglaries in the US in 2013. The wide majority of the rest were illegal, unforced entries that resulted from something like a window being left open. The odds of a criminal using technical means to bypass a security system are so small that the FBI doesn’t even track those statistics.
【C】 One of the main theoretical home-security concerns is whether or not a given system is vulnerable to being blocked from working altogether. With wired setups, the fear is that a burglar (入室盗贼) might be able to shut your system down simply by cutting the right cable. With a wireless setup, you stick battery-powered sensors up around your home that keep an eye on windows, doors, motion, and more. If they detect something wrong while the system is armed, they’ll transmit a wireless alert signal to a base station that will then raise the alarm. That approach will eliminate most cord-cutting concerns—but what about their wireless equivalent, jamming? With the right device tuned to the right frequency, what’s to stop a thief from jamming your setup and blocking that alert signal from ever reaching the base station?
【D】Jamming concerns are nothing new, and they’re not unique to security systems. Any device that’s built to receive a wireless signal at a specific frequency can be overwhelmed by a stronger signal coming in on the same frequency. For comparison, let’s say you wanted to “jam” a conversation between two people—all you’d need to do is yell in the listener’s ear.
【E】Security devices are required to list the frequencies they broadcast on-that means that a potential thief can find what they need to know with minimal Googling. They will, however, need to know what system they are looking for. If you have a sign in your yard declaring what setup you use, that’d point them in the right direction, though at that point, we are talking about a highly targeted, semi-sophisticated attack, and not the sort of forced-entry attack that makes up the majority of burglaries. It’s easier to find and acquire jamming equipment for some frequencies than it is for others.
【F】Wireless security providers will often take steps to help combat the threat of jamming attacks. SimpliSafe, winner of our Editors’ Choice distinction, utilizes a special system that’s capable of separating incidental RF interference from targeted jamming attacks. When the system thinks it’s being jammed, it’ll notify you via push alert (推送警报). From there, it’s up to you to sound the alarm manually.
【G】SimpliSafe was singled out in one recent article on jamming, complete with a video showing the entire system being effectively bypassed with handheld jamming equipment. After taking appropriate measure to contain the RF interference to our test lab, we tested the attack out for ourselves, and were able to verify that it is possible with the right equipment. However, we also verified that SimpliSafe’s anti-jamming system works. It caught us in the act, sent an alert to my smartphone, and also listed our RF interference on the system’s event log. The team behind the article and video in question make no mention of the system, or whether or not it detected them.
【H】We like the unique nature of that software. It means that a thief likely wouldn’t be able to Google how the system works, then figure out a way around it. Even if they could, SimpliSafe claims that its system is always evolving, and that it varies slightly form system to system, which means there wouldn’t be a universal magic formula for cracking it. Other systems also seem confident on the subject of jamming. The team at Frontpoint addresses the issue in a blog on its site, citing their own jam protection software and claiming that there aren’t any documented cases of a successful jam attack since the company began offering wireless security sensors in the 1980s.
【I】Jamming attacks are absolutely possible. As said before, with the right equipment and the right know-how, it’s possible to jam any wireless transmission. But how probable is it that someone will successfully jam their way into your home and steal your stuff?
【J】 Let’s imagine that you live in a small home with a wireless security setup that offers a functional anti-jamming system. First, a thief is going to need to target your home, specifically. Then, he’s going to need to know the technical details of your system and acquire the specific equipment necessary for jamming your specific setup. Presumably, you keep your doors locked at night and while you’re away, so the thief will still need to break in. That means defeating the lock somehow, or breaking a window. He’ll need to be jamming you at this point, as a broken window or opened door would normally release the alarm. So, too, would the motion detectors in your home, so the thief will need to continue jamming once he’s inside and searching for things to steal. However, he’ll need to do so without tripping the anti-jamming system, the details of which he almost certainly does not have access to.
【K】At the end of the day, these kinds of systems are primarily designed to protect against the sort of opportunistic smash-and-grab attack that makes up the majority of burglaries. They’re also only a single layer in what should ideally be a many-sided approach to securing your home, one that includes common sense things like sound locks and proper exterior lighting at night. No system is impenetrable, and none can promise to eliminate the worst case completely. Every one of them has vulnerabilities that a knowledgeable thief could theoretically exploit. A good system is one that keeps that worst-case setting as improbable as possible while also offering strong protection in the event of a less-extraordinary attack.

答案解析：36. It is possible for burglars to make jamming attacks with the necessary equipment and skill.
[I] As said before, with the right equipment and the right know-how, it’s possible to jam any wireless transmission.
解析：这里要注意介词前后以及连词前后的单词！注意with the necessary equipment and skill，尤其注意这里的名词equipment和skill都是文章中心名词，因此可以拿来作为我们的定位词。那么对应到原文中，equipment是原词重现，而skill替换了原文中的know-how，同时形容词在此处也发生了替换，由right替换为necessary，虽然应注意形容词的替换，但是大家更要注意名词的替换。
37. Interfering with a wireless security system is similar to interfering with a conversation.
[D] For comparison, let’s say you wanted to “jam” a conversation between two people—all you’d need to do is yell in the listener’s ear.
解析：此处首先注意题目中出现了一个重要的短语be similar to，出现be similar to表示两个事物要做比较了，同样地，要找出来谁和谁作比较，那么这里比较的内容是“interfering with a wireless security system”和“interfering with a conversation”，conversation与原文的中心词是相对应，因此锁定conversation以及be similar to。此外，在读文章的时候要注意特殊符号，譬如D段末尾的这句话，此外我们发现be similar to替换了原文的comparison, conversation为原词重现。
38. A burglar has to continuously jam the wireless security device to avoid triggering the alarm, both inside and outside the house.
[J] So, too, would the motion detectors in your home, so the thief will need to continue jamming once he’s inside and searching for things to steal. However, he’ll need to do so without tripping the anti-jamming system, the details of which he almost certainly does not have access to.
39. SimpliSafe provides devices that are able to distinguish incidental radio interference from targeted jamming attacks.
[F] SimpliSafe, winner of our Editors’Choice distinction, utilizes a special system that’s capable of separating incidental RF interference form targeted jamming attacks.
40. Only a very small proportion of burglaries are committed by technical means.
[B] The most likely type of burglary by far is the unsophisticated crime of opportunity, usually involving a broken window or some forced entry. According to the FBI, crimes like these accounted for roughly two-thirds of all household burglaries in the US in 2013. The wide majority of the rest were illegal, unforced entries that resulted from something like a window being left open.
41. It is difficult to crack SimpliSafe as its system keeps changing.
[H] Even if they could, SimpliSafe claims that its system is always evolving, and that it varies slightly form system to system, which means there wouldn’t be a universal magic formula for cracking it.
解析：通过SimpliSafe大写名词定位至F、G、H三段，注意此句出现时的引导词even if，后面的信息要着重注意。system keeps changing替换掉了原文中的varies slightly from system to system，cracking对应原文中的crack。
42. Wireless devices will transmit signals so as to activate the alarm once something wrong is detected.
[C] If they detect something wrong while the system is armed, they’ll transmit a wireless alert signal to a base station that will then raise the alarm.
解析：先来判断题目中可以用来定位的词，题目中出现so as to及once，它们的前后词要注意，因此我们锁定transmit signals以及active the alarm，同时注意once之后的something wrong。这道题较难定位，因为定位句出现在段落中，但Ｃ段中出现了一处if连词，给了大家一个提示，同时我们找到了对应关键词transmit signals、activate以及something wrong。
43. Different measures should be taken to protect one’s home from burglary in addition to the wireless security system.
[K] At the end of the day, these kinds of systems are primarily designed to protect against the sort of opportunistic smash-and-grab attack that makes up the majority of burglaries. They’re also only a single layer in what should ideally be a many-sided approach to securing your home.
解析：题目中的different measures以及protect one’s home from burglary可作为定位词，对应K段首句出现的many-sided approach以及protect against。
44. SimpliSafe’s device can send a warning to the house owner’s cellphone.
[G] It caught us in the act, sent an alert to my smartphone, and also listed our RF interference on the system’s event log.

答案解析：36. It is possible for burglars to make jamming attacks with the necessary equipment and skill.
[I] As said before, with the right equipment and the right know-how, it’s possible to jam any wireless transmission.
解析：这里要注意介词前后以及连词前后的单词！注意with the necessary equipment and skill，尤其注意这里的名词equipment和skill都是文章中心名词，因此可以拿来作为我们的定位词。那么对应到原文中，equipment是原词重现，而skill替换了原文中的know-how，同时形容词在此处也发生了替换，由right替换为necessary，虽然应注意形容词的替换，但是大家更要注意名词的替换。
37. Interfering with a wireless security system is similar to interfering with a conversation.
[D] For comparison, let’s say you wanted to “jam” a conversation between two people—all you’d need to do is yell in the listener’s ear.
解析：此处首先注意题目中出现了一个重要的短语be similar to，出现be similar to表示两个事物要做比较了，同样地，要找出来谁和谁作比较，那么这里比较的内容是“interfering with a wireless security system”和“interfering with a conversation”，conversation与原文的中心词是相对应，因此锁定conversation以及be similar to。此外，在读文章的时候要注意特殊符号，譬如D段末尾的这句话，此外我们发现be similar to替换了原文的comparison, conversation为原词重现。
38. A burglar has to continuously jam the wireless security device to avoid triggering the alarm, both inside and outside the house.
[J] So, too, would the motion detectors in your home, so the thief will need to continue jamming once he’s inside and searching for things to steal. However, he’ll need to do so without tripping the anti-jamming system, the details of which he almost certainly does not have access to.
39. SimpliSafe provides devices that are able to distinguish incidental radio interference from targeted jamming attacks.
[F] SimpliSafe, winner of our Editors’Choice distinction, utilizes a special system that’s capable of separating incidental RF interference form targeted jamming attacks.
40. Only a very small proportion of burglaries are committed by technical means.
[B] The most likely type of burglary by far is the unsophisticated crime of opportunity, usually involving a broken window or some forced entry. According to the FBI, crimes like these accounted for roughly two-thirds of all household burglaries in the US in 2013. The wide majority of the rest were illegal, unforced entries that resulted from something like a window being left open.
41. It is difficult to crack SimpliSafe as its system keeps changing.
[H] Even if they could, SimpliSafe claims that its system is always evolving, and that it varies slightly form system to system, which means there wouldn’t be a universal magic formula for cracking it.
解析：通过SimpliSafe大写名词定位至F、G、H三段，注意此句出现时的引导词even if，后面的信息要着重注意。system keeps changing替换掉了原文中的varies slightly from system to system，cracking对应原文中的crack。
42. Wireless devices will transmit signals so as to activate the alarm once something wrong is detected.
[C] If they detect something wrong while the system is armed, they’ll transmit a wireless alert signal to a base station that will then raise the alarm.
解析：先来判断题目中可以用来定位的词，题目中出现so as to及once，它们的前后词要注意，因此我们锁定transmit signals以及active the alarm，同时注意once之后的something wrong。这道题较难定位，因为定位句出现在段落中，但Ｃ段中出现了一处if连词，给了大家一个提示，同时我们找到了对应关键词transmit signals、activate以及something wrong。
43. Different measures should be taken to protect one’s home from burglary in addition to the wireless security system.
[K] At the end of the day, these kinds of systems are primarily designed to protect against the sort of opportunistic smash-and-grab attack that makes up the majority of burglaries. They’re also only a single layer in what should ideally be a many-sided approach to securing your home.
解析：题目中的different measures以及protect one’s home from burglary可作为定位词，对应K段首句出现的many-sided approach以及protect against。
44. SimpliSafe’s device can send a warning to the house owner’s cellphone.
[G] It caught us in the act, sent an alert to my smartphone, and also listed our RF interference on the system’s event log.

[I] As said before, with the right equipment and the right know-how, it’s possible to jam any wireless transmission.
解析：这里要注意介词前后以及连词前后的单词！注意with the necessary equipment and skill，尤其注意这里的名词equipment和skill都是文章中心名词，因此可以拿来作为我们的定位词。那么对应到原文中，equipment是原词重现，而skill替换了原文中的know-how，同时形容词在此处也发生了替换，由right替换为necessary，虽然应注意形容词的替换，但是大家更要注意名词的替换。
37. Interfering with a wireless security system is similar to interfering with a conversation.
[D] For comparison, let’s say you wanted to “jam” a conversation between two people—all you’d need to do is yell in the listener’s ear.
解析：此处首先注意题目中出现了一个重要的短语be similar to，出现be similar to表示两个事物要做比较了，同样地，要找出来谁和谁作比较，那么这里比较的内容是“interfering with a wireless security system”和“interfering with a conversation”，conversation与原文的中心词是相对应，因此锁定conversation以及be similar to。此外，在读文章的时候要注意特殊符号，譬如D段末尾的这句话，此外我们发现be similar to替换了原文的comparison, conversation为原词重现。
38. A burglar has to continuously jam the wireless security device to avoid triggering the alarm, both inside and outside the house.
[J] So, too, would the motion detectors in your home, so the thief will need to continue jamming once he’s inside and searching for things to steal. However, he’ll need to do so without tripping the anti-jamming system, the details of which he almost certainly does not have access to.

40. Only a very small proportion of burglaries are committed by technical means.
[B] The most likely type of burglary by far is the unsophisticated crime of opportunity, usually involving a broken window or some forced entry. According to the FBI, crimes like these accounted for roughly two-thirds of all household burglaries in the US in 2013. The wide majority of the rest were illegal, unforced entries that resulted from something like a window being left open.
41. It is difficult to crack SimpliSafe as its system keeps changing.
[H] Even if they could, SimpliSafe claims that its system is always evolving, and that it varies slightly form system to system, which means there wouldn’t be a universal magic formula for cracking it.
解析：通过SimpliSafe大写名词定位至F、G、H三段，注意此句出现时的引导词even if，后面的信息要着重注意。system keeps changing替换掉了原文中的varies slightly from system to system，cracking对应原文中的crack。
42. Wireless devices will transmit signals so as to activate the alarm once something wrong is detected.
[C] If they detect something wrong while the system is armed, they’ll transmit a wireless alert signal to a base station that will then raise the alarm.
解析：先来判断题目中可以用来定位的词，题目中出现so as to及once，它们的前后词要注意，因此我们锁定transmit signals以及active the alarm，同时注意once之后的something wrong。这道题较难定位，因为定位句出现在段落中，但Ｃ段中出现了一处if连词，给了大家一个提示，同时我们找到了对应关键词transmit signals、activate以及something wrong。
43. Different measures should be taken to protect one’s home from burglary in addition to the wireless security system.

As a person who writes about food and drink for a living, I couldn’t tell you the first thing about Bill Perry or whether the beers he sells are that great. But I can tell you that I like this guy. That’s because he plans to ban tipping in favor of paying his servers an actual living wage.
I hate tipping.
I hate it because it’s an obligation disguised as an option. I hate it for the post-dinner math it requires of me. But mostly, I hate tipping because I believe I would be in a better place if pay decisions regarding employees were simply left up to their employers, as is the custom in virtually every other industry.
Most of you probably think that you hate tipping, too. Research suggests otherwise. You actually love tipping! You like to feel that you have a voice in how much money your server makes. No matter how the math works out, you persistently view restaurants with voluntary tipping systems as being a better value, which makes it extremely difficult for restaurants and bars to do away with the tipping system.
One argument that you tend to hear a lot from the pro-tipping crowd seems logical enough: the service is better when waiters depend on tips, presumably because they see a benefit to successfully veiling their contempt for you. Well, if this were true we would all be slipping a few 100-dollar bill to our doctors on the way out their doors, too. But as it turns out, waiters see only a tiny bump in tips when they do an exceptional job compared to a passable one. Waiters, keen observers of humanity that they are, are catching on to this; in one poll, a full 30% said they didn’t believe the job they did had any impact on the tips they received.
So come on, folks: get on board with ditching the outdated tip system. Pay a little more upfront for your beer or burger. Support Bill Perry’s pub, and any other bar or restaurant that doesn’t ask you to do drunken math.
21、What can we learn about Bill Perry from the passage?
A He runs a pub that serves excellent beer.
B He intends to get rid of the tipping practice.
C He gives his staff a considerable sum for tips.
D He lives comfortably without getting any tips.
答案解析：
46. B）He intends to get rid of the tipping practice.
22、What is the main reason why the author hates tipping?
A It sets a bad example for other industries.
B It adds to the burden of ordinary customers.
C It forces the customer to compensate the waiter.
D It poses a great challenge for customers to do math.
答案解析：
47. C）It forces the customer to compensate the waiter.
解析：本题从问题上来看属于细节题，所以要根据题目中的the author hates tipping和main reason来定位，同时根据顺序原则，我们可定位到了第三段but mostly之后，“I hate tipping because I believe I would be in a better place if pay decisions regarding employees were simply left up to their employers, as is the custom in virtually every other industry”，译文为“我讨厌小费是因为如果服务员的报酬仅是由雇主提供，我会处于更有利的位置，正如其他行业的惯例一样”，这说明餐饮行业的小费机制跟其他行业不同，强迫消费者支付劳动报酬，这和C选项的含义较为接近。因此，正确答案为C。
23、Why do many people love tipping according to the author?
A They help improve the quality of the restaurants they dine in.
B They believe waiters deserve such rewards for good service.
C They want to preserve a wonderful tradition of the industry.
D They can have some say in how much their servers earn.
答案解析：
48. D）They can have some say in how much their servers earn.
解析：本题属于细节题。根据顺序原则以及关键词many people love tipping返回原文，我们可以定位至第四段第二行的“You like to feel that you have a voice in how much money your server makes”，你喜欢这种能够决定服务员挣多少钱的感觉。D项中have some say in与原文中的have a voice in意思相同，earn与make意思相同。选项D是原文的同义替换，故正确。
24、What have some waiters come to realize according to a survey?
A Service quality has little effect on tip size.
B It is in human nature to try to save on tips.
C Tips make it more difficult to please customers.
D Tips benefit the boss rather than the employees.
答案解析：
49. A）Services quality has little effect on tip size.
解析：本题属于细节题。题目问的是调查中一些服务员的观点，根据顺序原则，这在第五段的最后一句话中有所体现。“...in one poll, a full 30% said they didn’t believe the job they did had any impact on the tips they received”，译文为：一些服务员认为他们的工作对收到的小费没有影响。not any impact on替换为了选项A中的little effect on，the tips they received 替换为了选项A中的tip size，可以看出，选项A属于对原文句子的同义替换。
25、What does the author argue for in the passage?
A Restaurants should calculate the tips for customers.
B Customers should pay more tips to help improve service.
C Waiters deserve better than just relying on tips for a living.
D Waiters should be paid by employers instead of customers.
答案解析：
50. D）Waiters should be paid by employers instead of customers.
解析：最后一题属于作者的观点态度题，要跟文章主旨挂钩，多半出现在文章最后一段的最后一行。文章最后提到了“support Bill Perry’s pub”,说明 作者支持Bill Perry的观点，而Bill的观点在开头第一段最后一句已经提到过了，“...he plans to ban tipping in favor of paying his servers an actual living wage”，他觉得应该取消小费，并相应地给服务员实际工资。ban tipping替换为了选项D中的instead of customers, 即不是由消费者来决定的；而actual living wage替换为了选项D中的paid by employers。因此正确答案为D。
Part III Reading Comprehension
In the past, falling oil prices have given a boost to the world economy, but recent forecasts for global growth have been toned down, even as oil prices sink lower and lower. Does that mean the link between lower oil prices and growth has weakened?
Some experts say there are still good reasons to believe cheap oil should heat up the world economy. Consumers have more money in their pockets when they’re paying less at the pump. They spend that money on other things, which stimulates the economy.
The biggest gains go to countries that import most of their oil like China, Japan, and India. But doesn’t the extra money in the pockets of those countries’consumers mean an equal loss in oil-producing countries, cancelling out the gains? Not necessarily, says economic researcher Sara Johnson. “Many oil producers built up huge reserve funds when prices were high, so when prices fall they will draw on their reserves to support government spending and subsidies (补贴) for their consumers.”
But not all oil producers have big reserves. In Venezuela, collapsing oil prices have sent its economy into free-fall.
Economist Carl Weinberg believes the negative effects of plunging oil prices are overwhelming the positive effects of cheaper oil. The implication is a sharp decline in global trade, which has plunged partly because oil-producing nations can't afford to import as much as they used to.
Sara Johnson acknowledges that the global economic benefit from a fall in oil prices today is likely lower than it was in the past. One reason is that more countries are big oil producers now, so the nations suffering from the prices drop account for a larger share of the global economy.
Consumers, in the U.S. at least, are acting cautiously with the savings they’re getting at the gas pump, as the memory of the recent great recession is still fresh in their mind. And a number of oil-producing countries are trimming their gasoline subsidies and raising taxes, so the net savings for global consumers is not as big as the oil price plunge might suggest.
26、What does the author mainly discuss in the passage?
A The reasons behind the plunge of oil prices.
B Possible ways to stimulate the global economy.
C The impact of cheap oil on global economic growth.
D The effect of falling oil prices on consumer spending.
答案解析：
51. C）The impact of cheap oil on global economic growth.
解析：本题是主旨题。根据顺序原则，定位到文章第一段末尾“Does that mean the link between lower oil prices and growth has weakened? ”这是一个疑问句，符合文章答案出现的位置。问题指出，这意味着更低的油价和经济增长之间的关系削弱了吗？这句话点明了主题，只需在选项中找到表明这两者关系的即可。C选项The impact of cheap oil on global economic growth，其中impact表示影响，同时指出了cheap oil和global economic growth，所以C是正确答案。
27、Why do some experts believe cheap oil will stimulate the global economy?
A Manufacturers can produce consumer goods at a much lower cost.
B Lower oil prices have always given a big boost to the global economy.
C Oil prices may rise or fall but economic laws are not subject to change.
D Consumers will spend their savings from cheap oil on other commodities.
答案解析：
52. D）Consumers will spend their savings from cheap oil on other commodities.
解析：本题是细节题。根据文章顺序原则以及题目中的experts定位到第二段，第二段指出“Consumers have more money in their pockets when they’re paying less at the pump. They spend that money on other things, which stimulates the economy”，消费者在加油站花的少了，就会有更多的钱由自己支配，同时将这笔钱用于别的地方，从而刺激经济的发展，D选项中指出省钱用来买别的，选项中的saving对应原文中的paying less，other commodities对应原文中的other things，因此D是正确答案。
28、What happens in many oil-exporting countries when oil prices go down?
A They suspend import of necessities from overseas.
B They reduce production drastically to boost oil prices.
C They use their money reserves to back up consumption.
D They try to stop their economy from going into free-fall.
答案解析：
53. C）They use their money reserves to back up consumption.
解析：本题属于细节题。通过when oil prices go down定位至第三段最后的引语部分，“Many oil producers built up huge reserve funds when prices were high, so when prices fall they will draw on their reserves to support government spend and subsidies for their consumers”，后半句中指出,价格下调了，他们就会利用储备资金来支撑政府支出并补贴消费者。C选项中money reserves对应原文中的reserves，back up对应support，consumptions对应consumers，因此C是正确答案。
29、How does Carl Weinberg view the current oil price plunge?
A It is one that has seen no parallel in economic history.
B Its negative effects more than cancel out its positive effects.
C It still has a chance to give rise to a boom in the global economy.
D Its effects on the global economy go against existing economic laws.
答案解析：
54. B）Its negative effects more than cancel out its positive effects.
解析：细节题。由人名定位到第五段“...the negative effects of plunging oil prices are overwhelming the positive effects of cheaper oil”，油价大幅下跌的负面影响远超低油价的正面效果。B选项中more than cancel out对应原文中的overwhelming，因此B是正确答案。
30、Why haven’t falling oil prices boosted the global economy as they did before?
A People are not spending all the money they save on gas.
B The global economy is likely to undergo another recession.
C Oil importers account for a larger portion of the global economy.
D People the world over are afraid of a further plunge in oil prices.
答案解析：
55. A）People are not spending all the money they save on gas.
解析：细节题。依据问题中的why以及顺序原则定位到原文第六、七段，第六段“One reason is that more countries are big oil producers now, so the nations suffering from the prices drop account for a larger share of the global economy”， 译文为：原因之一就是现在更多的国家已经变成大型的石油生产商了，因此价格下跌，遭受损失的国家在全球经济中所占的份额更大。C选项中写的是oil importers（石油进口国），与原文中的石油生产商不同。第七段中提出“Consumers, in the U.S. at least, acting cautiously with the savings they’re getting at the gas pump, as the memory of the recent great recession is still fresh in their mind”， 至少美国的消费者非常谨慎地对待他们在加油站省下来的钱。因此人们并没有将在加油费上省下来的钱全部花掉。A是正确答案。
