　　19．D綜合推斷題。女士說(shuō)她擔(dān)心自己的車(chē)，因?yàn)檐?chē)又進(jìn)修理廠了，還說(shuō)這次應(yīng)該是剎車(chē)出了問(wèn)題，由again再結(jié)合其說(shuō)話內(nèi)容可知，車(chē)子以前也壞過(guò)，故選D。

　　20．C信息明示題。男士說(shuō)修理女士的車(chē)應(yīng)該花不了多少錢(qián)，像女士這樣的美國(guó)車(chē)，零部件都比較便

　　宜，故選C。

　　21．B信息明示題。女士說(shuō)那名修理工是自己鄰居推薦的，他以前也給自己修過(guò)車(chē)，而且價(jià)錢(qián)似乎也比較合

　　理，故選B。

　　22．A信息明示題。男士問(wèn)女士今天下課后是否需要搭他的車(chē)回家，很明顯是在提議送女士回家，故選A。

　　考點(diǎn)

　　watch out意為戒備，提防，與watch相關(guān)的短語(yǔ)還有：watch over照看，看守，負(fù)責(zé)，如：The mother bird is watching over her young．鳥(niǎo)媽媽正照看著自己的孩子。watch for留心找尋，耐心等候，如：Youll have to watch for the right moment．你得等候適當(dāng)?shù)臅r(shí)機(jī)。

　　23．D綜合推斷題。女士一開(kāi)始就介紹說(shuō)科學(xué)團(tuán)體首次確定了太陽(yáng)系以外的行星的存在，雖然人類(lèi)知道存在著某些遙遠(yuǎn)的恒星，但卻是最近才得知有些恒星有圍繞自己運(yùn)行的行星，接下來(lái)的對(duì)話也是圍繞這些行星展開(kāi)的，故選D。

　　24．A綜合推斷題。女士說(shuō)天文學(xué)家是通過(guò)間接方法來(lái)發(fā)現(xiàn)那些行星的，他們測(cè)量出母星發(fā)出的光頻的細(xì)微變化，還觀察到母星似乎前后擺動(dòng)，最終確定這都是由于沿軌道運(yùn)行的行星的牽引而引起的，由此推斷，科學(xué)家們是通過(guò)研究母星外觀的變化來(lái)確定行星的存在的，故選A。

　　25．B信息明示題。女士說(shuō)科學(xué)家們可以利用新的望遠(yuǎn)鏡來(lái)分解、分析光線，進(jìn)而希望了解這些行星的化學(xué)成分，故選B。

　　考點(diǎn)

　　break down此處意為分解，分為，還有以下含義：①停止運(yùn)轉(zhuǎn)，失效，如：The engine broke down．引擎壞了。②失敗，瓦解，如：The peace talks have broken down．和平會(huì)談破裂了。③感情失去控制，如：He broke down and wept when he heard the bad news．他聽(tīng)到壞消息時(shí)不禁痛哭起來(lái)。

　　Conversation One

　　M: Is this table on the comer OK?

　　W: Sure. We can sit here.

　　M: Oh, you paused to get anything on your tray.

　　W: Yeah. I guess Im just not that hungry.

　　M: Whats the matter? Arent you feeling well?

　　W: Well, Ive been really worried. Its my car. Ifs in the shop, again!

　　M: Really? Whats wrong this time?

　　W: I dont know exactly. Somethings wrong with the brakes, I think.

　　M: Well, at least that shouldnt cost you much to fix. Parts are cheaper for all the American cars like yours. Did the mechanic say how much it would cost?

　　W: He said hed call me with an estimate later on today.

　　M: Watch out he doesnt try to take advantage of you.

　　W: What do you mean?

　　M: Well, some car mechanics, if they think that someone doesnt know much about cars, they might try to overcharge that person.

　　W: Maybe so. But I trust this guy. He was recommended by one of my neighbors. He has done some work for me in the past and his prices seemed to be reasonable.

　　M: Oh, thats good to know. Maybe Ill try using him in the future. By the way, do you need a ride home after class today?

　　W: Oh, Ill sure appreciate it. Its really tough getting around without a car when you live off campus.

　　Conversation Two

　　M: Doctor Cole, thank you for agreeing to this interview for the Daily Campus News. Can you tell us about what you and your colleagues discuss at the annual astronomy society meeting last month?

　　W: Yes. For the first time ever the scientific community has established the existence of planets outside our own solar system. Of course we knew that certain distant stars existed, but only recently did we learn that several of them are orbited by their own planets.

　　M: Why did it take so long to locate these planets?

　　W: Well, you have to understand that they are a billion times dimmer than their parent stars. It would be like trying to see the light of a candle next to a huge explosion. We dont currently have a telescope that can be used to see them.

　　M: But if the astronomers didnt see the planets through a telescope, how did they find them?

　　W: By a very indirect method. The astronomers measured subtle distortions in the frequency of the light from the parent stars and observed that some of the stars seem to rock back and forth. They determined that this was caused by gravitational pull from orbiting planets.

　　M: There is a powerful new telescope being built in Arizona. Will that help them see these planets?

　　W: They should be able to see them at least in the form of small spots of light. And then the scientists will be able to break down and analyze this light. By doing this, they hope to learn about the chemical composition of these planets-oxygen and ozone molecules, for example, would be telltale signs of life on these planets.

　　M: Im looking forward to hearing more when the telescope is in operation. And Im sure our readers would be interested too.

　　Questions 23 to 25 are based on the conversation you have just heard.

　　23. What is the conversation mainly about?
