Does a bee know what is going on in its mind when it navigates its way to distant food sou

rces and back to the hive (蜂房), using polarized sunlight and the tiny magnet it carries as a navigational aid？ Or is the bee just a machine, unable to do its mathematics and dance its language in any other way？ To use Donald GrifTm's term, does a bee have awareness, or to use a phrase I like better, can a bee think and imagine？

There is an experiment for this, or at least an observation, make long ago by Karl Von Frisch and more recently confirmed by James Gould at Princeton, Biologists who wish to study such things as bee navigation, language, and behavior. in general have to train their bees to fly from the hive to one or another special place. To do this, they begin by placing a source of sugar very close to the hive so that the bees (considered by their trainers to be very dumb beasts) can learn what the game is about. Then, at regular intervals, the dish or whatever is moved progressively father and farther from the hive in increments (增长) of about 25 percent at each move. Eventually, the target is being moved 100 feet or more at a jump, very far from the hive. Sooner or later, while this process is going on, the biologists shifting the dish of sugar will find the bees are out there waiting for them, precisely where the next position had been planned. This is an uncomfortable observation to make.

With what subject is the passage mainly concerned？

A．The bee, a social animal.

B．Navigational techniques of bees.

C．Testing the awareness of bees.

D．The bee hive, nature's candy shop.

Newspapers, along with reporting the news, instruct, entertain, and give opinions. An impo

rtant way for reading a large, big-city newspaper is knowing how to take it apart. Can you find these separate sections: world news, national and local news, sports, business, entertainment, opinions, classified ads？ Does your paper have other sections？

News stories give facts, not the author's opinions. Editorials do the opposite, you can expect an editorial to take sides. Some newspaper editorials have a by-line with the author's name, but many newspapers have unsigned editorials. These reflect the opinions of the publisher or editor.

You can be a better reader if you know what to expect in a newspaper. For example, you can expect headlines to omit unnecessary words. You can expect to find the most important facts in the lead paragraph(the first paragraph) of a news story. You can expect important news items to be on the front page. You can expect less important items to be on the inside pages.

Most of all, the more you know about the current news, the more you will understand what is in the newspaper; important stories are generally presented one day and followed up on following days. So, an important way for reading newspapers is reading one frequently.

A good way to read a large newspaper is______.

A．to do some paper-cutting

B．to read it from cover to cover

C．to find separate sections

D．to predict what is inside the newspaper

There is no creature that does not need sleep or complete rest every day.

If you want to know why, just try going without sleep for a long period of time. You will discover that your mind and body would become too tired to work properly. You would become irritable and find it hard to think clearly or concentrate on your work. So sleep is quite simply the time when the cells of your body recover from the work of the day and build up supplies of energy for the next period of activity.

One of the things we all know about sleep is that we are unconscious in sleep. We do not know what is going on around us. But that doesn't mean the body stops all activity. The important organs continue to work during sleep, but most of the body functions are slowed down.

For example, our breathing becomes slower and deeper. The heart beats more slowly, and the blood pressure is lower. Our arms and legs become limp(柔软的) and muscles are at rest. It would be impossible for our body to relax to such an extent if we were awake. So sleep does for us what the most quiet rest can not do.

Your body temperature becomes lower when you are asleep, which is the reason people go to sleep under some kind of covers. And even though you are unconscious, many of your reflexes(习惯性思维) still work. For instance, if someone tickles(使觉得痒) your foot, you will put it away in your sleep, or even brush a fly from your forehead. You do these things without knowing it.

If you don't have as much sleep as your body needs, you will ______.

A．work properly

B．think clearly

C．keep your attention on your work

D．easily get angry

All that we really need to plot out the future of our universe are a few good measurements

. This does not mean that we can sit down today and outline the future course of the universe with anything like certainty. There are still too many things we do not know about the way the universe is put together. But we do know exactly what information we need to fill in our knowledge, and we have a pretty good idea of how to go about getting it.

Perhaps the best way to think of our present situation is to imagine a train coming into a switchyard. All of the switches are set before the train arrives, so that its path is completely determined. Some switches we can see, others we can not. There is no ambiguity if we can see the setting of a switch: we can say with confidence that some possible futures will not materialize and others will. At the unseen switches, however, there is no such certainty. We know the train will take one of the tracks leading out, but we have no idea which one. The unseen switches are the true decision points in the future, and what happens when we arrive at them determines the entire subsequent course of events.

When we think about the future of the universe, we can see our "track" many billions of years into the future, but after that there are decision points to be dealt with and possible fates to consider. The goal of science is to reduce the ambiguity at the decision points and find the true road that will be followed.

According to the passage, it is difficult to be certain about the distant future of the universe because we ______.

A．have too many conflicting theories

B．do not have enough funding to continue our research

C．are not sure how the universe is put together

D．have focused on investigations of the moon and planets

Shopping for clothes is not the same experience for a man as it is for a woman. A man goes

shopping because he needs something.

His purpose is settled and decided. He knows what he wants and he just finds it and buys it, but cares little about the price. All men simply walk into a shop and ask the assistant for what they want. If the shop has it, the salesman quickly takes it out, and the business of trying it on follows at once. If all is well, the deal(买卖) can be and is often completed in less than five minutes, with hard any chat and to everyone's satisfaction.

For a man, small problems may begin when the shop does not have what he wants, or does not have exactly what he wants. In that case the salesman tries to sell the customer something else—he offers the nearest he can to the thing asked for. He would say, "I know this jacket is not the style. you want, Sir, but would you like to try it on for size？ It happens to be the color you mentioned." Few men have patience (耐心 ) with this treatment, and the usual answer is, "This is the right color and may be the right size, but I should be wasting my time and yours by trying it on."

Now how docs a woman go about buying clothes？ In almost every respect (方面) she does so quite differently. Her shopping is not often based on need. She has never fully made up her mind about what she wants, and she is only "having a look around". She is always open to what the salesman tells her, even to what her friends tell her. She will try on any number of things. What is most important in her mind is the thought of finding something that everyone thinks suits her. Besides, most women have an excellent sense of value when they boy clothes. The), are always ready for the unexpected bargain (便宜货). Faced with a roomful of dresses, a woman may easily spend an hour going from one counter to another before selecting the dresses she wants to try on. It takes time, but surely it is enjoyable to women shoppers. Most dress shops provide chairs for the waiting husbands.

When a man is buying clothes, ______.

A．he buys cheap things and does not care about the quality

B．he chooses things that others recommend

C．he does not mind how much he has to pay for the right things

D．he buys good quality things, so long as they are not too expensive
