Question 13 is based on the conversation you have just heard.

听力原文

W: The metro was absolutely terrible this morning.

M: Oh, was there a delay?

W: No. But the train was so packed that I could barely move, and it was difficult to breathe, too. At every station, more people squeezed in, and I got pushed further and further inside. When I got to my station, I could hardly get out. (12) [Once I did get out, I was totally exhausted.] 

M: That sounds like a nightmare. Why didn’t you take the bus?

W: The bus takes twice as long, and it’s just as crowded.

M: Well, what’s the alternative? Haven’t you got a car? 

W: I’ve got a driver’s license, but that’s all. (13) [I’m saving up to buy something reasonably small and cute. But it’s still a bit expensive for me, and it’ll take a while before I have enough money.]

M: Have you thought about getting an electric motorbike?

W: I considered that for maybe a minute, (14) [but honestly, I’ve just seen too many horrible accidents involving those dangerous monsters.] 

M: What about those popular shared bikes? You could register to use one.

W: Yeah, that’s a possibility. There are always several of those bikes out in front of our apartment complex.

M: Or you could just walk to work.

W: Well, it’s five kilometers from home to the office, but you’ve given me a thought. I could take a change of clothes and jog to work. But at this time of year, the air pollution is a real problem.

M: Oh yeah. I didn’t think of that. Get a taxi if you really have to.

W: Well, that’s an expensive way to get to work.

M: (15) [Not if you use a ride sharing app.]  

W: (15) [Good idea. I’ll download one immediately. Thank you.]

13. Why hasn’t the woman got her own car? （为什么女士自己没买车？）

解析：A。录音中间部分女士提到，自己正在攒钱买车，但目前还没有攒够（it’ll take a while before I have enough money）。A项与此相符，故为正确答案。

错项排除：B项中的traffic jams和D项中的is used to taking public transport在录音中没有依据，故均可排除。录音中女士说自己有驾照，故C项错误。
