“Lemons” in Used Car Market
Suppose that you, a college student of somewhat limited means, are in the market for a used pickup truck. The following ad in a local used car publication catches your eye.
1993 Ford Ranger, bilk, 4WD,a/c,
AM/FM/cass., showroom condition.
Call 555-1234 after 5 p.m.
This is exactly the kind of vehicle you want, so you call to inquire about the price. The price you are quoted over the phone2 is $2,000 lower than the Price for this model with this equipment listed in a used car guidebook. Instead of being ecstatic, however, you are suspicious.
For many products, when you must pay less than the going rate, you believe you are getting a great deal. This is not necessarily the case for used cars or other durable goods (washing machines and television sets, for example) because with expensive products—or, what is essentially the same thing, products with high replacement costs—you must be particularly careful about getting a “l(fā)emon,” or a product of substandard quality.
In addition to asking the price, the age of a car —or any other consumer durable—is a factor when you are trying to determine whether a seller is attempting to unload a lemon. While people hold off until they have put many thousands of a car that is “too new” as you would a car that is “too good” a deal. In fact, you are probably willing to pay a high for a high quality used car. While this price would certainly be acceptable to the seller, the competitive market might not facilitate such trades.
1. The beginning of this passage assumes that college students.
A) are very clever but not very rich.
B) are very capable but not very diligent.
C) have limited material resources.
D) are not rich.
2. The passage indicates that, sometimes when you find a product of an unexpectedly low price,
A) you are very happy.
B) you are rather suspicious.
C) you are filled with happiness as well as surprise.
D) you feel uneasy.
3. “Lemon” in this passage refers to
A)a kind of fruit.
B)a kind of new car.
C)a kind of expensive and high-quality car.
D)a product of inferior quality.
4. If you want to know if the seller is trying to unload a lemon, you
A) take the age of the car into consideration.
B) take the price of the lemon into consideration.
C)consider how many miles the car has run.
D) consider both the price as well as the age of the car.
5. It can be concluded from the passage that in the used car market,
A) used cars are generally cheap.
B) used cars are actually expensive.
C) used cars are actually brand new.
D) car buyers are willing to pay a high price for a used car.
Passage 2
Electronic Mail
During the past few years, scientist the world over have suddenly found themselves productively engaged in task they once spent their lives avoiding -- writing, any kind of writing but particularly letter writing. Encouraged by electronic mail's surprisingly high speed, convenience and economy, people who never before touched the stuff are regularly, skillfully, even cheerfully tapping out a great deal of correspondence.
Electronic networks, woven into the fabric of scientific communication these days, are the route to colleagues in distant counties, shared data, bulletin boards and electronic journals. Anyone with a personal computer, a modem and the software to link computers over telephone lines can sign on. An estimated five million scientists have done so with more joining every day, most of them communicating through a bundle of interconnected domestic and foreign routes known collectively as the internet, or net.
E-mail is staring to edge out the fax, the telephone, overnight mail, and of course, land mail. It shrinks time and distance between scientific collaborators, in part because it is conveniently asynchronous (writers can type while their colleagues across time zones sleep; their message will be waiting). If it is not yet speeding discoveries, it is certainly accelerating communication.
Jeremy Bernstei, the physicist and science writer, once called E-mail the physicist's umbilical cord. Lately other people, too, have been discovering its connective virtues. Physicists are using it; college students are using it, everybody is using it, and as a sign that it has come of age, the New Yorker has accelerates its liberating presence with a cartoon -- an appreciative dog seated at a keyboard, saying happily, "On the Internet, nobody knows you're a dog."
1. The reasons given below about the popularity of E-mail can be found in the passage Except
A. direct and reliable
B. time-saving in delivery
C. money-saving
D. available at any time
2. How is the Internet or net explained in the passage?
A. Electronic routes used to read home and international journals.
B. Electronic routes used to fax or correspond overnight.
C. Electronic routes waiting for correspondence while one is sleeping.
D. Electronic routes connected among millions of users, home and abroad.
3. What does the sentence "If it is not speeding discoveries, it is certainly accelerating communication" most probably mean?
A. The quick speed of correspondence may have ill-effects on discoveries
B. Although it does not speed up correspondence, it helps make discoveries.
C. It quickens mutual communication even if it does not accelerate discoveries.
D. It shrinks time for communication and accelerates discoveries.
4. What does the sentence "On the Internet, nobody knows you're a dog." Imply in the last paragraph?
A. Even dogs are interested in the computer.
B. E-mail has become very popular.
C. Dogs are liberated from their usual duties.
D. E-mail deprives dogs of their owners' love
5. What will happen to fax, land mail, overnight mail, etc. according to the writer?
A. Their functions cannot be replaced by E-mail.
B. They will co-exist with E-mail for a long time.
C. Less and less people will use them.
D. They will play a supplementary function to E-mail.
Passage 3
Stress Level Tied to Education Level
People with less education suffer fewer stressful days, according to a report in the current issue of the Journal of Health and Social Behavior.
However, the study also found that when 1ess-educated people did suffer stress it was more severe and had a larger impact on their health.
From this researchers have concluded that the day-to-day factors that cause stress are not random.Where you are in society determines the kinds of problems that you have each day, and how well you will cope with them.
The research team interviewed a national sample of 1.03 1 adults daily for eight days about their stress level and health.People without a high school diploma reported stress on 30 percent of the study days,people with a high school degree reported stress 38 percent of the time,and people with college degrees reported stress 44 percent of the time.
"Less advantaged people are less healthy on a daily basis and are more likely to have downward turns in their health?!眑ead researcher Dr.Joseph Grzywacz,of Wake Forest University Baptist Medical Center, said in a prepared statement.“The downward turns in health were connected with daily stressors.a(chǎn)nd the effect of daily stressors on their health is much more devastating for the less advantaged.”
Grzywacz suggested follow-up research to determine why less-educated people report fewer days of stress when it is known their stress is more acute and chronic.
“If something happens every day, maybe it’snot seen as a stressor”Grzywacz says.“Maybe it is just 1ife.”
詞匯:
stressor n.緊張刺激物

Passage 1
“Lemons” in Used Car Market
1. D。該題問“文章的開始部分認為大學生怎樣?”。文章第一段的第一句說“假設你是一個大學生,經(jīng)濟上并不富有”,所以答案是D(不富有)。注意:A說“很聰明,但不太富有”不正確,因為原文中并沒提到“聰明”。
2. B。該題問“文章表示,當你找到了一件價格出奇的底的商品時,你會怎樣?”。原文說“instead of being ecstatic, however, you are suspicious…”,即“你會懷疑”,所以答案是B。
3. D。該題問“這篇文章中的‘檸檬’指什么?”。‘檸檬’在文章中是加了引號的,所以不是水果。原文說“You must be particularly careful about getting a "lemon" or a product of substandard quality.”,所以‘檸檬’在文章中指“低質量的產(chǎn)品”。
4. D。該題問“如果你想知道是否賣方正試圖傾銷‘檸檬’,則你該怎樣做?”。文章最后一段表明,汽車買主通??紤]兩個因數(shù):價格和使用時間的長短。

4.B.問題中所引用的句子的句意是“在因特網(wǎng)上沒有人知道你是條狗?!?,利用該句周圍的句子的句意判斷(前句說每個人都在使用電子郵件),該引文是暗示電子郵件很受歡迎。(注意:在文章中應該是中心語義承接。)
5.C.利用“傳真”,“平郵”,“快郵”作為答案相關句在第3段段首句中發(fā)現(xiàn)答案相關句,該句說電子郵件正開始取代“傳真”,“平郵”,“快郵”??梢奀的說法與該句的說法一致。
Passage 3
Stress Level Tied to Education Level
1. B。分析: 問題句說“壓力程度與...緊密相關”. 社會地位與教育程度緊密相關的結合, 而文章主題說“緊張程度與教育程度相關”,因此推測“社會地位”最可能與“緊張程度”發(fā)生關系, 因此推測B很可能是答案。還可以在文章中進行進一步的確認:
(第3段) From this, researchers have concluded that the day-to-day factors that cause stress are not random.Where you are in society determines the kinds of problems that you have each day, and how well you will cope with them.劃線句說“你在社會中的地位決定了你每天遇到什么樣的問題,決定了你會怎樣解決這些問題?!苯Y合前句內容可知: 劃線句中提到的“問題”都是造成“造成壓力的因素”, 因此判斷壓力程度和社會地位相關, 因此B是答案。
2. A。 分析: 問題句說“有1,031位成年人。。接受了采訪”, 借助問題句中的特征詞1.03 1 adults作為答案線索, 這樣找到答案相關句: The research team interviewed a national sample of 1.03 1 adults daily for eight days about their stress level and health.該句說“研究小組采訪了從全國抽樣而產(chǎn)生的1,031名成年人, 對這些人連續(xù)采訪了8天,內容問及他們遭受到的壓力的程度和他們的健康狀況。 ”因此判斷A(每天進行, 連續(xù)進行了8天)是答案。
3.D. 分析: 問題問“哪個小組報告承受壓力的天數(shù)最多?”,結合文章主題: 壓力程度與教育程度相關, 結合文章開頭所陳述的權威性的觀點: People with less education suffer fewer stressful days(接受的教育越少, 感受到壓力的時間越短), according to a report in the current issue of the Journal of Health and Social Behavior.因此判斷D(有大學學歷的人)承受壓力的天數(shù)最多。
4.A. 分析:問題句說“人們的優(yōu)勢越小,。。越大?”利用問題句中的修飾結構less advantaged作為答案線索, 這樣找到答案相關句:
(第5段)“Less advantaged people are less healthy on a daily basis and are more likely to have downward turns in their health, ” lead researcher Dr.Joseph Grzywacz,of Wake Forest University Baptist Medical Center, said in a prepared statement. “The downward turns in health were connected with daily stressors.a(chǎn)nd the effect of daily stressors on their health is much more devastating for the less advantaged.”該段提到“健康的滑坡與每天的緊張刺激物有關系,而這些刺激物對他們健康的影響更加具有破壞性”,也就是說“壓力對他們的健康具有更大的影響” ,因此判斷A(壓力對其健康造成的影響(更大))是答案。
5. C。 問題句說“受教育程度較低的人他們報告的承受壓力的天數(shù)更少,這可能是因為。。?!保?借助常識和對文章主題內容的理解: 壓力與受教育程度相關, 判斷C和D可能是答案(A和B離文章主題內容太遠),利用問題句中的修飾詞Less—educated作為答案線索, 這樣找到答案相關句:
Grzywacz suggested follow-up research to determine why less-educated people report fewer days of stress when it is known their stress is more acute and chronic.這句話說“要進行后續(xù)的研究以確定為什么受教育程度較低的報告的承受壓力的天數(shù)更少, ”, 而接下來的句子說: “If something happens every day, maybe it’s not seen as a stressor”Grzywacz says.“Maybe it is just 1ife.”該劃線句說“如果某種事情每天動發(fā)生, 也許它就不會被看成是壓力刺激物了?!苯Y合上一句的內容來看,這句話應該是在分析原因, 因此判斷C(壓力是他們生活中一個很平常的因素)是答案。
