C
1970 was World Conservation（自然保护）Year. The United Nations wanted everyone to know that the world is in danger. They hoped that people would act quickly in order to conserve nature（大自然）. Here is one example of the problem. At one time there were 1,300 different plants, trees and flowers in Holland, but now only 866 remain. The others have been destroyed by modern man. It is said that there are tens of thousands of kinds of animals in the world, but now many have died out（绝种）. We are changing the earth, the air and water, and everything that grows and lives . We can't live without these things. If we continue like this, we shall destroy ourselves.
What will happen in the future？Perhaps it is more important to ask“What must we do now？”The people who will be living in the world of tomorrow are the young of today. A lot of them know that conservation is necessary. Many are helping to save our world. They plant trees, build bridges across rivers and so on. In a small town in the United States a large group of girls cleaned the banks of  11 kilometres of their river. Young people may hear about conservation through a record called“No one's going to change our world.”It was made by the Beatles, Cliff Richard and other singers. The money from it will help to conserve wild animals.

　　There are 25,000 kinds of bees identified in the world. The most well-known are the honey bee. In the United States there are known 3,500 species. Most bees do not live in large groups, they are solitary(独居的)bees. The honey bee is not a native of the United States. The first bees were brought to the U.S. from Holland. Later other bees were brought from many other countries. South America had some honey bees, but they did not produce much honey.

　　When honey bees were brought to the United States, native American called them“white man's flies”. Soon bees became a known sight in America.

　　In Brazil, honey bees did not survive well and scientists brought African bees to Brazil. These bees were found to be aggressive(好斗的) and mistakenly escaped into the wild. These bees are very common in Brazil now.

　　Beekeepers raise bees for honey, but more often they raise them to pollinate crops. Pollination occurs when the bee lands on a flower and some of the pollen(花粉)gets stuck to the bees' hairy legs. The next time the bee lands, some of the pollen falls off her legs and onto another flower, allowing it to reproduce.

　　Beekeepers have been raising bees for their honey for thousands of years. The first beekeepers kept their bees in hollow logs or clay pots. Now they keep the bees in wooden hives. When beekeepers raise bees for honey, they must remove part of the hive to retrieve (获取) the honey. They must“calm”the bees by using a special smoker. The smoke is puffed out around the bees and the bees move slower and are not as aggressive.

1．What's the best title for the passage?

[　　]

A．An Introduction to Bees.　　　　　　B．Why Bees Are Kept.

2．What's the meaning of the underlined word“pollinate”?

[　　]

A．Make something fertile (结果实的) with pollen.

B．Get pollen away from.

C．Plant.

D．Harm.

3．From the passage we can infer that _____.

[　　]

A．bees want their honey to he taken away in order to get more room

B．all bees are kept by raisers

D．it is easy to retrieve the honey

　　In the United States, it is important to be on time, or punctual, for an appointment, a class, a meeting, etc. However, this may not be true in all countries. An American professor discovered this difference while teaching a class in a Brazilian university. The two-hour class was scheduled (制定) to begin at 10 a. m and end at 12 a. m. On the first day, when the professor arrived on time, no one was in the classroom Many students came after 10 a. m. Several arrived after 10:30 a. m. Two students came after 11 a. m. Although all the students greeted the professor as they arrived, few apologized for their lateness. Were these students being rude? He decided to study the students' behavior.

　　The professor talked to American and Brazilian students about lateness in both an informal and a formal situation: lunch with a friend and in a university class, respectively. He gave them an example and asked them how they would react. If they had a lunch appointment with a friend, the average American student defined (定义) lateness as 19 minutes after the agreed time. On the other hand, the average Brazilian student felt the friend was late after 33 minutes.

　　In an American university, students are expected to arrive at the appointed hour. In contrast, in Brazil, neither the teacher nor the students always arrive at the appointed hour. Classes not only begin at the scheduled time in the United States, but they also end at the scheduled time. In the Brazilian class, only a few students leave the class at noon; many remain past 12:30 to discuss the class and ask more questions. While arriving late may not be very important in Brazil, neither is staying late.

　　The explanation for these differences isn't simple. People from Brazilian and North American cultures have different feelings about lateness. In Brazil, the students believe that a person who usually arrives late is probably more successful than a person who is always on time. In fact, Brazilians expect a person with high social position to arrive late, while in the United States lateness is usually considered to be disrespectful and unacceptable. As a result, if a Brazilian is late for an appointment with a North American, the American may misread the reason for the lateness and become angry.

　　As a result of his study, the professor learned that the Brazilian students were not being disrespectful to him. Instead, they were simply behaving in the appropriate (合适的) way for a Brazilian student in Brazil. In the end, the professor was able to change his own behavior so that he could feel comfortable in the new culture.

　　We had hardly got above the clouds over the airport when a calm voice said over the loudspeaker:“For technical reasons we shall be returning immediately to London Airport. Please keep your seatbelts fastened.”

　　I was rather surprised and glanced at the old lady next to me. She had been very chatty while we were waiting to take off.

　　“I'm going to New York to visit some relatives there. I always sleep wonderfully welt whenever I get into a plane.”she had told me.

　　“What's happening? Are we going to crash?”an American in front of me demanded.

　　I looked out again. The ground was rushing up at us with shocking speed. We were already so low that I could make out cars and even people.

“It's only a slight emergency,”a stewardess told me with a tense smile.

Suddenly there was a sickening bump and we were rushing along the runway at a terrifying speed. The brakes screeched (发出尖锐刺耳的声音). The engines roared even more loudly. We came to a trembling stop. The cabin crew quickly opened the emergency exits and the passengers began sliding down huge, stocking-like chutes (滑道) to the ground. A fire engine was already putting out the fire in one engine.
