  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.

  And indeed, she seemed to he in a very deep sleep already.

  Just then a passenger behind me shouted,“Oh, my God! The wing's on fire.”

  I looked out of the window and my blood froze. Smoke and flames were pouring out of one of the engines. The plane was already turning and losing altitude fast.

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

  The cabin crew were already moving up and down the aisle (走道), reassuring (安慰) people, saying things like,“It's just all right. There's no need to worry. Now, if you just sit still, everything will be all right. Don't get up. Don't get upset.”

  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. I had to shake the old lady violently to wake her up.

  “What's wrong? Surely the journey isn't over already! I mean, have we got to New York?”she asked sleepily.

I walked alongside my father, clutching his right hand.All my clothes were new: the black shoes, the green school uniform, and the red cap.They did not make me happy, however, as tins was the day I was to be thrown into school for the first time.I tried in vain lo convince him that I did nothing wrong all the way, but it didn’t help.
When we.arrived at the sate we could see the courtyard, vast and full of boys and girls.I hesitated and clung to his hand, but he gently pushed me from him."Be a man, "he said."today you truly begin your life.You will find me waiting for you when it’s time to leave."
I took a few steps.Then the faces of the boys and girls came into view.I did not know a single one of them, and none of them knew me.I felt I was a stranger who had lost his way.But then some boys began to glance at me in curiosity, and one of them came over and asked, " Who brought you? "
"My father," I whispered.
’’My father’s dead, " he said simply.
I did not know what to say.The gate was now closed.Some of the children burst into tears.The bell rang.A lady came along, followed by a group of men.The men began soiling us into ranks.We were formed into an intricate pattern in the great courtyard surrounded by high buildings.
Well, it seemed that my misgivings had had no basis.From the first moments I made many friends and fell in love with many girls.I had never imagined school would have this rich variety of experiences.
We played all sorts, of games.In the music room we sang our first songs.We also had our first introduction to language.We saw a globe of Earth, which revolved and showed the various continents and countries.We started lean-line numbers, and we were told the story of the Creator of the universe.We ate delicious food, took a little nap, and woke up to go on with friendship and love, playing and learning.
Our path, however, was not totally sweet and unclouded.We had to be observant and patient.It was not all a matter of playing and fooling around. Rivalries could bring about pain and hatred or give rise to fighting.And while the lady would sometimes smile, she would often yell and scold.Even more frequently
she would resort to physical punishment.
The bell rang, announcing the passing of the day and the end of work.The children rushed toward the gate, which was opened again.I said goodbye to friends and sweethearts and passed through the gate.I looked around but found no trace of my father, who had promised to be there.I stepped aside to wait.

D
Anyone for rocket salad? The Chinese are now growing huge vegetables from seeds they sent into space.
If you are the type who worries about the air miles travelled by fruits and vegetables, these beauties aren’t for you. It's because they have travelled a little further than most.
The seeds from which they grew were fired into space, where they orbited the earth for two weeks. Once they returned they were grown in hothouses, producing the monster kinds seen here.
China, which is behind these space fruits and vegetables, says they could be the answer to the world's food crisis.
The 21-pound tomatoes, nine-inch chillies, 15-stone pumpkins and large watermelons growing at the Guangdong Academy of Agricultural Sciences’ hothouses can feed many more than their smaller cousins, and may have more nutrients, the scientists say.
Researcher Lo Zhigang said, "Traditional agricultural development has taken us as far as we can go and demand for food from a growing population is endless. Space seeds offer the opportunity to grow fruits and vegetables bigger and faster. "
He admitted he and his colleagues could not explain why time in orbit caused the seeds to change genetic structure. But they guessed exposure to the cosmic(宇宙的)radiation that attacked the spacecraft in orbit, as well as the near zero gravity conditions, microgravity, could play a part.
"We don't think there's any threat to human health because the genes themselves do not change; just their order changes," he said. "With genetically-modified(GM)crops you have seen environmental problems because they have added genes that can damage other organisms. But with space seeds they don't gain genes; they can only lose them. "
He also claimed the Vitamin C content in some space vegetables was nearly three times higher than in common vegetables, while levels of zinc are also increased.
Western scientists are doubtful. NASA researchers who have experimented with seeds in space say there is not enough benefit to show the cost is reasonable.
63. What do the underlined words "these beauties" in Paragraph 2 probably refer to ______?
A. Beautiful views along the air routes.          B. Travelling experiences in space.
C. Seeds fired into space.                     D. Giant vegetables.
64. We can infer from Lo’s words in Paragraph 6 that _______.
A. our conventional agriculture has developed too slowly.
B. we are asking too much from nature
C. space seeds may help meet our demand for food
D. we'll grow crops in space in the future
65. Why the seeds changed their genetic structure _______.
A. remains to be proved
B. is discovered by Lo Zhigang
C. has something to do with the conditions in hothouses
D. is due to the radiation that attacked them directly
66. What can be inferred from the last paragraph?
A. Western scientists’ doubt is unreasonable.
B. Western scientists don’t believe that Chinese scientists have succeeded in the experiment.
C. Western scientists have proved space seeds to be of no benefit.
D. Western scientists think the cost of space seeds outweighs the benefits

It's really true what people say about English politeness: it's everywhere.When squeezing past someone in a narrow aisle, people say "sorry".When getting off a bus, English passengers say "thank you" rather than the driver.In Germany, people would never dream of doing these things.
After all, squeezing past others sometimes can't be avoided.and the bus driver is merely doing his job.I used lo think the same way, without questioning it, until I started traveling to the British Isles and came to appreciate some more polite ways of communicating with people.
People thank each other everywhere in England, all the time.When people buy something in a shop, customer and retail assistant in most cases thank each other twice or more.In Germany, it would be exceptional to hear more than one thank you in such a conversation.British students thank their lecturers when leaving the room.English employers thank their employees for doing their jobs as opposed to Germans, who would normally think that paying their workers money is already enough.
Another thing I observed during my stay was that English people rarely criticize others.Even when I was working and mistakes were pointed out to me.my employers stressed several times but none of their explanations were intended as criticism.It has been my impression that by avoiding criticism, English people are making an effort to make others feel comfortable.This also is shown in other ways.British men still open doors for women, and British men are more likely to treat women to a meal than German men.However, 1 do need to point out here that this applies to English men a bit more than it would to Scottish men' Yes, the latter are a bit tightfisted.
【小题1】What is the author's attitude towards English politeness?

A.He appreciates itB.He gives no personal opinion
C.He thinks it is artificialD.He thinks it goes too far.
【小题2】What can we learn about customers and retail assistants in Germany?
A.It's always a retail assistant who says thank you.
B.A customer never says thank you to a retail assistant.
C.They always say thank you to each other.
D.They may say thank you only once.
【小题3】We can learn from the last paragraph that Scottish men _____.
A.are more likely to be involved in a fighting.
B.are not so willing to spend money for women.
C.are more polite than English men.
D.treat women in a polite way.
【小题4】The author develops the text through the method of        .
A.giving commentsB.telling stories
C.making comparisonsD.giving reasons
