Some psychologists claim that people ________ (出门在外时可能会感到孤独).
New "fake fat" products appeared on store shelves in the United States recently, but not everyone is happy about it. Makers of the products, which contain a compound called olestra, say food manufacturers can now eliminate. Critics, however, say the new compound can rob the body of essential vitamins and nutrients (营养物) and can also cause unpleasant side effects in some people. So it's up to consumers to decide whether the new fat-free products taste good enough to keep eating.
Chemists discovered olestra in the late 1960s, when they were searching for a fat that could be digested by infants more easily. Instead of finding the desired fat, the researchers created a fat that can't be digested at all.
Normally, special chemicals in the intestines(肠)"grab" molecules of regular fat and break them down so they can be used by the body. A molecule of regular fat is made up of three molecules of substances called fatting acids.
The fatty acids are absorbed by the intestines and bring with them the essential vitamins A, D, E and K. When fat molecules are present in the intestines with any of those vitamins, the vitamins attach to the molecules and are carried into the bloodstream.
Olestra, which is made from six to eight molecules of fatty acids, is too large for the intestines to absorb. It just slides through the intestines without being broke down. Manufacturers say it's the ability to slide unchanged through the intestines that makes olestra so valuable as a fat substitute. It provides consumers with the taste of regular at without any bad effects on the body. But critics say olestra can prevent vitamins A, D, E and K from being absorbed. It can also prevent the absorption of carotenoids(类胡萝卜素), compounds that may reduce the risk of cancer, heart disease, etc.
Manufacturers are adding vitamins A, D, E and K as well as carotenoids to their products now. even so, some nutritionists are still concerned that people might eat unlimited amounts of food made with the fat substitute without worrying about how many calories they are consuming.
We learn from the passage that olestra is a substance that______.
A．contains plenty of nutrients
B．renders foods calorie-free while retaining their vitamins
C．makes foods easily digestible
D．makes foods fat-free while keeping them delicious
Imagine eating everything delicious you want -with none of the fat. That would be great, wouldn't it？

The wine that claims "It’s like taking a trip to France" wants you to think about a romantic evening in Paris as you walk along the street after a wonderful meal in an intimate cart. Of course, you don’t really believe that a wine can take you to France, but the goal of the ad is to get you to think pleasant, romantic thoughts about France and not about how the wine tastes or how expensive it may be. That little word "like" has taken you away from crushed grapes into a world of your own imaginative making. Who knows, maybe the next time you buy wine, you'll think those pleasant thoughts when you see this brand of wine, and you'll buy it.
How about the most famous "like" claim of all, "Winston tastes good like a cigarette should"？ Ignoring the grammatical error here, you might want to know what this claim is saying. Whether a cigarette tastes good or bad is a subjective judgment because what tastes good to one per son may well taste horrible to another. There are many people who say that all cigarettes taste terrible, other people who say only some cigarettes taste all right, and still others who say all cigarettes taste good.
The word "like" in an ad often focuses the consumer’s attention on ______.
A．what the advertiser says about the product
B．what magic the product really possesses
C．why the advertiser promotes the product
D．why the product is as good as promised
听力原文： Yuppies are young people who cam a lot of money and live in a style. that is too expensive for most people. If you are invited to a yuppie dinner party, don't be surprised if you are offered freshly-cooked insects as a first course. While the idea of eating fried insects fills most of us with horror, insect eating is becoming highly fashionable. For example, in the media industry, successful executives are often seen to eat fried or boiled insects from time to time while working at their desks. These safe-to-eat insects can be found and ordered on the Internet. And young people are logging on to exotic food websites and ordering samples of prepared insects to serve at their dinner parties. Although the idea of eating insects is probably disgusting to most of us, few people would claim that pigs, chickens and some kinds of seafood we often eat are examples of great beauty. One day insects could be marketed and sold as a food item in supermarkets.' According to their fans, they are not only high in protein and low in fat, but also very tasty. But until our attitudes to food change fundamentally, it seems that insect eaters will remain a select few.

A．Because we might be offered a dish of insects.
B．Because nothing but freshly cooked insects are served.
C．Because some yuppies like to horrify guests with insects as food.
