16、Question 16 is based on the passage you have just heard.
A Nodding one's head.
B Waving one's hand.
C Holding up the forefinger.
D Turning the right thumb down.
答案解析：
Body language, especially gestures, varies among cultures. For example, a nod of the head means "yes" to most of us. (16) But in Bulgaria and Greece a nod means "no" and a shake of the head means "yes". Likewise, a sign for OK, forming a circle with our forefinger and thumb, means zero in France and money in Japan. (17) Waving or pointing to an Arab business person would be considered rude because that is how Arabs call their dogs over. Folded arms signal pride in Finland, but disrespect in Fiji. The number of bows that the Japanese exchange on greeting each other, as well as the length and the depth of the bows, signals the social status each party feels towards the other. Italians might think you're bored unless you use a lot of gestures during discussions. (18) Many American men sit with their legs crossed with one ankle resting over the opposite knee. However, this would be considered an insult in Muslim countries, where one would never show the sole of the foot to a guest. Likewise, Americans consider eye contact very important, often not trusting someone who is afraid to look you in the eye. But in Japan and many Latin American countries, keeping the eyes lowered is a sign of respect. To look upon firmly in the eye is considered a sign of ill breeding and is felt to be annoying.

A They had to beg for food after the harvest.
B They grew wheat and corn on a small farm.
C They shared a small flat with their relatives.
D The children walked to school on dirt roads.
答案解析：
Three years ago, Puncha Maya, her husband and five children lived in a shaky flat in southern Nepal. Every morning, the parents walked the dirt roads seeking work in the rice fields. (19) After the harvest, the family went begging for food. Today, the Mayas own a small paper-bag making company. With the money they've earned, the Mayas have purchased a small plot, on which they grew vegetables and raise goats for additional income. In fact, the family has saved $ 68, this is remarkable in a country with an average annual income of $ 160.
Grace Mbakwa, her husband and eight children once lived hand-to-mouth in Cameroon. Today, the Mbakwas run a clothing manufacturing business and own a home. (20) They are able to send their children to school, at a cost of annual sum of $ 2,800.
The idea of starting her own business seemed impossible to Pilar Moya, a poor woman from Atahualpa, high in Ecuador's Andes Mountains. Today, however, she is one of the proud owners of a bakery specializing in sweet cakes.
(21) These businesses are part of economic revolution sweeping to developing world. The sponsor is the Trickle Up Program, a non-profit organization founded by New Yorkers Glen and Mildred Leet. This organization offers people like the Mayas, the Mbakwas and the Moyas modest $ 100 grands. Since 1979, the program has helped over 130,000 of the world's neediest people in 90 countries win small life-saving victories over poverty. And it has turned conventional thinking about foreign aid on its hand.

B They are vitally important to our life.

答案解析：
Take care of your teeth and your teeth will take care of you. (22) Your teeth are a living part of your body. They have nerves and blood vessels. Diseased teeth can cause pain, die and fall out. Plaque is the main enemy of healthy teeth. Everyone has plaque. (23) It is a sticky colorless film that coats the teeth. Plaque is always forming on the teeth, especially at the gum line. If plaque is not removed, it builds up and gets under the gum line. Plaque that is left on the teeth for some time hardens. The result is tooth decay and gum disease. (24) The bacteria in plaque live on sugar. They change sugar into acids, which break down the tooth’s harder outer covering. If left untreated, decay goes deeper and deeper into the tooth. After a while, the decay reaches the nerves and blood vessels of the inner tooth. By the time this happens, the tooth has probably started to ache. (25) In addition to tooth decay, there are also gum diseases to watch out for. The bacteria in plaque make poisons that attack the gums. Small pockets form around the teeth. The pockets trap more bacteria and food particles. Finally, the bone supporting the teeth is attacked and starts to shrink. Teeth become loose and may fall out. Adults lose most teeth this way. Keep your mouth healthy. When you brush your teeth, do a good job.
