You’re in a department store and you see a couple of attractive young women looking at a sweater. You listen to their conversation:
“I can’t believe it —a Lorenzo Bertolla! They are almost impossible to find. Isn’t it beautiful? And it’s a lot cheaper than the one Sara bought in Rome.”
They leave and you go over to see this incredible sweater．It's nice and the price is right．You've never heard of Lorenzo Bertolla, but those girls looked really stylish．They must know．So, you buy it．You never realize that those young women are employees of an advertising agency．They are actually paid to go from store to store, talking loudly about Lorenzo BertoHa clothes.
Every day we notice what people are wearing, driving and eating．If the person looks cool, the product seems cool, too．This is the secret of undercover（暗中影响的） marketing．Companies from Ford to Nike are starting to use it.
Undercover marketing is important because it reaches people that don't pay attention to traditional advertising．This is particularly true of the MTV generation----consumers between the age of 18 and 34．It is a golden group．They have a lot of money to spend, but they don't trust ads.
So advertising agencies hire young actors to "perform" in bars and other places where young adults go．Some people might call this practice deceptive, but marketing executive Jonathan Ressler calls it creative．"Look at traditional advertising．Its effectiveness is decreasing."
However, one might ask what exactly is "real" about of young women pretending to be enthusiastic about a sweater? Adverting executives would say it's no less real than an ad．The difference is that you know an ad is trying to persuade you to buy something．You don' t know when a conversation you overhear is just a performance.
1.The two attractive young women were talking so that they could ________.
A．get the sweater at a lower price B．be heard by people around

2.Lorenzo Bertolla is __________．

C．a clothing company in Rome D．the brand name of a sweater
3.Which of the following can be inferred from the passage?
A．The two girls are in fact employed by the Lorenzo Bertolla Company.
B．The MTV generation tend to be more easily influenced by ads.
C．Traditional advertising is becoming less effective because it's too direct.
D．Undercover marketing will surely be banned soon by the government.
4.Which of the following would be the best title for the text?
A．Two Attractive Shoppers B．Lorenzo Bertolla Sweaters
C．Ways of Advertising D．Undercover Marketing
It was once thought that air pollution affected only the area immediately around large cities with factories and/or heavy automobile traffic. Today, we know that although these are the areas with the worst air pollution, the problem is literally worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the entire eastern half of the United States and led to health warnings even in rural areas away from any major concentration of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be affected by air pollution. Some scientists feel that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels(coal and oil) creating a greenhouse effect-holding in heat reflected from the earth and raising the world’s average temperature. If this view is correct and the world’s temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Boston, Miami, and New Orleans will be under water.
Another view, less widely held, is that increasing particulate matter in the atmosphere is blocking sunlight and lowering the earth’s temperature-a result that would be equally disastrous（灾难的）. A drop of just a few degrees could create something close to a new ice age, and would make agriculture difficult or impossible in many of our top farming areas. At present we do riot know for sure that either of these conditions will happen(though one recent government report prepared by experts in the field concluded that the greenhouse effect is very likely). Perhaps, if we very lucky, the two tendencies will offset each other and the world’s temperature will stay about the same as it is now.
1.As pointed out at the beginning of the passage, people used to think that air pollution ______.
A．caused widespread damage in the countryside

2.As far as the greenhouse effect is concerned, the author _____________.
A．shares the same view with the scientists
B．is uncertain of its occurrence
C．rejects it as being ungrounded（无根据的）
D．thinks that it will increasingly destroy the world soon
3.It can be inferred from the passage that .
A．raising the world’s temperature a little would not do much harm to life on the earth
B．lowering the world’s temperature a little would lead to agricultural disasters
C．almost no temperature variations have occurred over the past decade
D．the world’s temperature will remain stable forever
4.This passage is primarily concerned with .
A．the greenhouse effect in the world
B．the measures to adjust the climate
C．the potential effect of air pollution
D．the measures to protect the environment
