Recordings of angry bees are enough to send big, tough African elephants running away, a new study says. Beehives (蜂窝)-either recorded or real-may even prevent elephants from damaging farmer's crops.
In 2002, scientist Lucy King and her team found that elephants avoid certain trees with bees living in them. Today, Lucy wants to see if African honeybees might discourage elephants from eating crops. But before she asked farmer to go to the trouble of setting up beehives on their farms, she needed to find out if the bees would scare elephants away.
Lucy found a wild beehive inside a tree in northern Kenya and set up a recorder. Then she threw a stone into the beehive, which burst into life. Lucy and her assistant hid in their car until the angry bees had calmed down. Next，Lucy searched out elephant families in Samburu National Reserve in northern Kenya and put a speaker in a close to each family.
From a distance, Lucy switched on the pre-recorded sound of angry bees while at the same time recording the elephants with a video camera. Half the elephant groups left the area within ten seconds. Out of a total of 17 groups, only one group ignored the sound of the angry bees. Lucy reported that all the young elephants immediately ran to their mothers to hide under them. When Lucy Played the sound of a waterfall (瀑布) instead of the angry bees to many of the same elephant families, the animals were undisturbed. Even after four minutes, most of the groups stayed in one place.
Lucy is now studying whether the elephants will continue to avoid the sound of angry bees after hearing it several times. She hasn't tested enough groups yet to know, but her initial (最初的) results were promising enough to begin trials with farmers. She has now begun placing speakers in the fields to see if elephants are frightened away.

If you go into the forest with friends， stay with them. If you don‘t， you may get lost. If you get lost， this is what you should do. Sit down and stay where you are. Don’t try to find your friends—let them find you. You can help them find you by staying in one place. There is another way to help your friends or other people to find you. You can shout or whistle three times. Stop. Then shout or whistle three times again. Any signal given three times is a call for help. Keep up shouting or whistling. Always three times together. When people hear you， they will know that you are not just making a noise for fun. They will let you know that they have heard your signal. They will give you two shouts or two whistles. When a signal is given twice， it is an answer to a call for help. If you don’t think that you will get help before night comes，try to make a little house with branches. Make yourself a bed with leaves and grass. When you need some water，you have to leave your little branch house to look for it. Don’t just walk away. Pick off small branches and drop them as you walk in order to go back again easily. When you are lost，the most important thing to do is to stay in one place.

Doctors say anger can be an very harmful emotion（情绪）unless you learn how to deal with it. They warn that angry feelings can lead to heart disease， stomach problems， headaches， emotional problems and possibly cancer.
Anger is a normal emotion that we all feel from time to time. Some people express anger openly in a calm reasonable way. Others burst with anger， losing control of themselves. But other people repress their anger. They cannot or will not express it.
For years many doctors thought that repressing anger was more dangerous to a person’s health than expressing it. They said that when a person is angry， the brain gives off the same hormones（激素）that are produced during tense situations. They speed the heart rate， raise blood pressure， or sugar into the blood and narrow the blood vessels（脉管）to the interstices（空隙）. In general， the person feels excited and ready to act.
Doctors said that repressing these feelings only makes the feelings continue. And this can lead to many medical problems. Doctors thought a person could prevent these problems by letting the anger out by expressing it freely. But recently some doctors held a different view. They said that people who express anger repeatedly and violently did become， in fact， more and not less angry.
They said this，too，can cause medical problems.
Some doctors say that both repressing and expressing anger can be dangerous. They believe that those who express anger violently may be more likely to develop heart disease， and they believe that those who keep their anger inside may face a greater danger of high blood pressure.
Doctors say the solution（解决办法）is learning how to deal with anger. They say the first step is to admit that you are angry and to recognize the real cause of the anger， and then decide if the cause is serious. If it is， they say： “Do not express your anger while angry. Wait until your anger has cooled down and you are able to express yourself calmly and reasonably. ”

English is the most widely used language in the history of our planet. One in every seven human beings can speak it. More than half of the world’s books and three quarters of international mail are in English. Of all languages, English has the largest vocabulary — perhaps as many as two million words.
However, let’s face it: English is a crazy language. There is no egg in an eggplant, neither pine nor apple in a pineapple and no ham in a hamburger. Sweet-meats are candy, while sweetbreads, which aren’t sweet, are meat.
We take English for granted. But when we explore its paradoxes (探讨它的矛盾), we find that quicksand can work slowly, boxing rings are square, public bathrooms have no baths in them.
And why is it that a writer writes, but fingers don’t fing, grocers don’t groce, and hammers don’t ham? If the plural of tooth is teeth, shouldn’t the plural of booth be beeth? One goose, two geese — so one moose, two meese?
How can a slim chance and a fat chance be the same, while a wise man and a wise guy are opposites? How can overlook and oversee be opposites, while quite a lot and quite a few are alike? How can the weather be hot as hell one day and cold as hell the next?
English was invented by people, not computers, and it reflects (反映) the creativity of human beings. That’s why, when stars are out, they are visible (能看见的); but when the lights are out, they are invisible. And why, when I wind up my watch, I start it; but when I wind up this essay, I end it.
1. According to the passage ______.
A. sweet-meats and sweetbreads are different things

A. Beeth. B. Geese. C. Meese. D. Tooth.
3. Which of the following includes two items which have the similar meaning?
A. A wise man and a wise guy. B. Overlook and oversee.
C. Quite a lot and quite a few. D. Hot as hell and cold as hell.
4. The underlined words “wind up” in the last paragraph probably mean “______”.
A. blow B. roll up C. get hurt D. finish

A. clever B. crazy C. lazy D. dull
