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.

Verbal skills in another culture can generally be mastered if one studies hard enough,

but nonverbal skills are much more difficult to learn. Nonverbal behavior. includes areas such as eye contact, facial expressions, postures, gestures, and the use of time, space,and territory. The messages sent by body language and the way we arrange time and space have always been open to interpretation. Does a raised eyebrow mean that your boss doubts your statement or just that she is seriously considering it？ Does a closed door to an office mean that your coworker is angry or just that he is working on a project that requires concentration？ Deciphering nonverbal communication is difficult for people who are culturally similar, and it is even more troublesome when cultures differ.

In Western cultures, for example, people perceive silence as negative. It suggests rejection, unhappiness, facial expression, regret, embarrassment, or ignorance.

However, the Japanese admire silence and consider it a key to success. A Japanese proverb says, “Those who know do not speak; those who speak do not know.”

Over 60 percent of Japanese businesswomen said that they would prefer to marry silent men. Silence is equated with wisdom.

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
