【正文】 ’ll stay in California for two weeks.W:Yes. Your friend Andy. He was your classmate at London University, wasn’t he?Q:What is the probable relationship between the two speakers?【解析】［C］男士稱女士為 honey, 證明兩人關(guān)系親密，由此可判斷兩人關(guān)系為夫妻。: When will the meeting begin?W:According to the schedule it should be at 9:30. It will last for an hour and a half.Q:When will the meeting be closed?【解析】［B］根據(jù)女士所說的話，根據(jù)時(shí)刻表會(huì)議9∶30開始，持續(xù)一個(gè)半小時(shí)，那么即11：00結(jié)束。17. W:If I were you, I would take a plane instead of a bus. It will take you forever to go there.M:But flying makes me so nervous.Q: What does the man prefer to do?【解析】［C］ 女士建議男士乘飛機(jī)，男士回答說飛行讓他精神緊張，說明男士還是愿意乘坐公共汽車。18. W:I’ve been thinking about my cousin a lot today.M:Why not go over for a visit?Q:What does the man mean?【解析】［A］男士說的 Why not go over for a visit 即是在建議女士去看望她的堂兄。Now you’ll hear two long conversations.Conversation OneW:OK, last night you were supposed to read an article about human bones. Are there any ments about it?M:Well, to begin with, I was surprised to find out there was so much going on in bones. I always assumed they were pretty lifeless.W:Well, that’s an assumption many people make. But the fact is bones are made of dynamic living tissue that requires continuous maintenance and repair.M:Right. That’s one of the things I found so fascinating about the article the way the bones repair themselves.W:OK. So can you tell us how the bones repair themselves?M:Sure. See, there are two groups of different types of specialized cells in the bone that work together to do it. The first group goes to an area of the bone that needs repair. This group of cells produces the chemical that actually breaks down the bone tissue, and leaves a hole in it. After that the second group of specialized cells es and produces the new tissue that fills in the hole that was made by the first group. W:Very good. This is a very plex process. In fact, the scientists who study human bones don’t pletely understand it yet. They are still trying to find out how it all actually works. Specifically, because sometimes after the first group of cells leaves a hole in the bone tissue, for some reason, the second group doesn’t pletely fill in the hole. And this can cause real problems. It can actually lead to a disease in which the bone bees weak and is easily broken.M:OK, I get it. So if the scientists can figure out what makes the specialized cells work, maybe they can find a way to make sure the second group of cells pletely fills the hole in the bone tissue every time. That’ll prevent the disease from ever occurring.Questions 19 to 22 are based on the conversation you have just heard. is the discussion mainly about?【解析】［C］對(duì)話一開始就談?wù)撊祟惞趋赖膯栴}，女士說 But the fact is bones are made of dynamic living tissue that requires continuous maintenance and repair. 后面的對(duì)話都是針對(duì)這個(gè)話題展開的討論，可見整個(gè)對(duì)話討論的話題是骨骼的自我修復(fù)能力。 is the function of the first group of specialized cells discussed in the talk?【解析】［C］男士解釋了第一組細(xì)胞的作用，第一組細(xì)胞生成一種化學(xué)物質(zhì)分解骨組織(This group of cells produces the chemical that actually breaks down the bone tissue...)，由此可見答案是They break down bone tissue. does the professor say about scientists who study the specialized cells in human bones?【解析】［B］女士說這種特殊細(xì)胞作用于人類骨骼的過程相當(dāng)復(fù)雜，事實(shí)上，連研究人類骨骼的科學(xué)家都不能完全了解這個(gè)過程。從這一句中可以知道：In fact, the scientists who study human bones don’t pletely understand it yet. 所以答案即是這些科學(xué)家也不完全知道這些細(xì)胞如何工作。 to the student, which is one important purpose of studying specialized cells in human bones?【解析】［A］學(xué)習(xí)這些人類骨骼中的特殊細(xì)胞的重要目的是為了學(xué)習(xí)如何預(yù)防骨頭疾病。從男士的這一句話中可看出：That’ll prevent the disease from ever occurring. 這樣可以在疾病發(fā)生之前預(yù)防疾病，可見［A］符合題意。Conversation TwoM: Hi Diana, mind if I sit down?W: Not at all, Jerry. How have you been?M:Good. But I’m surprised to see you on the city bus. Your car in the shop?W:No. I’ve just been thinking a lot about the environment lately. So I decided the air will be a lot cleaner if we all use public transportation when we could.M:I’m sure you are right. The diesel bus isn’t exactly pollution free.W:True. They’ll be running a lot cleaner soon. We were just talking about that in my environmental engineering class.M:What could the city do? Install pollution filters in all their buses?W:They could, but those filters make the engines work harder and really cut down on the fuel efficiency. Instead they found a way to make their engines more efficient.M: How?W:Well, there is a material that’s a really good insulator. And a thin coat of it gets sprayed on the certain part of the engine.M: An insulator?W:Yeah. What it does is reflect back the heat of burning fuel. So the fuel will burn much hotter and burn up more pletely.M:So a lot less unburned fuel es out to pollute the air.W:And the bus will need less fuel. So with the saving on fuel cost, they say this will all pay for itself in just six months.M:Sounds like people should all go out and get some this stuff to spray their car engines.W:Well, it’s not really that easy. You see, normally, the materials are fine powder. To melt it so you can spray a coat of it on the engine parts, you first have to heat it over 10,000 degrees and then, well, you get the idea. It’s not something you or I will be able to do ourselves.Questions 23 to 25 are based on the conversation you have just heard. is the conversation mainly about?【解析】［C］女士說為了環(huán)保應(yīng)該多乘坐公共交通設(shè)備，因此之后的話題便圍繞如何節(jié)能保護(hù)環(huán)境的問題展開。這段對(duì)話主要討論的是公共汽車的節(jié)能問題，討論了如何讓公共汽車燃料更有效的利用，因此［C］符合題意。 did the woman decide to ride the city bus?【解析】［B］對(duì)話開頭部分就交代了此題答案，那位女士說她不開自己的車而乘坐公共汽車是為了降低環(huán)境污染。從她提到的So I decided the air will be a lot cleaner if we all use public transportation when we could 即可得知。 is the new material?【解析】［D］這種新的材料是在引擎部位噴灑的一種絕緣材料。從女士的話中there is a material that’s a really good insulator. And a thin coat of it gets sprayed on the certain part of the engine即可得出。這種材料的用途是將燃料燃燒的熱量反射回去，從而達(dá)到提高效率的結(jié)果。Section BPassage OneA guide dog is a dog especially trained to guide a blind person.
