阅读下列短文,从每题所给的四个选项中选出最佳选项。

  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.

1.When did the emergency occur?

A.We are not told.

B.Just before the plane landed in New York.

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

Below is some advice on how to sleep better.
1. Maintain a regular bed and wake time schedule
Go to bed at the same time every night. Choose a time when you normally feel tired, so that you don’t toss or turn. Try not to break this routine on weekends when it may be tempting to stay up late. If you want lo changeyour bedtime, help your body adjust by making the changein small daily increments, such as 15 minutes earlier or later each day. As with your bedtime, try to maintain yourregular wake-time even on weekends.
2.Fight after-dinner drowsiness(睡意)
If you find yourself getting sleepy before your bed-time, get off the couch and do something mildly stimulating to avoid falling asleep, such as washing the dishes, calling a friend, or getting clothes ready for the next day. If you give in to the drowsiness, you may wake up later in the night and have trouble getting back to sleep.
3. Keep your room dark and cool
When it’s time to sleep, make sure that your environment is dark. Even dim light —especially those from TV or computer screens —can confuse the body clock. Heavy curtains or shades can help block light from windows, or you can try an eye mask to cover your eyes. The temperature of your bedroom also affects sleep. A bedroom that is too hot or too cold can interfere with quality sleep.
4. Turn off your television
Many people use the television to fall asleep or relaxat the end of the day. You may even have a television inyour bedroom. However, television actually stimulates themind, rather than relaxing it. Part of this is due to con­tent. Late night news and prime time shows frequently have disturbing, violent material. Even non-violent pro­gramming can have commercials that are jarring and loud.
5. Exercise early
Exercise helps promote restful sleep if it is done sev­eral hours before you go to bed. Exercise can help you fall asleep faster and sleep more soundly— as long asit ’s done at the right time. Try to finish exercising at least three hours before bed or work out earlier in the day.
6. Consult your doctor
Use a sleep diary and talk to your doctor. Note what type of sleep problem is affecting your sleep or if you aresleepy when you wish to be awake and alert. Try these tips and record your sleep and sleep-related activities in a sleep diary. If problems continue, discuss the sleep diary with your doctor. There may be an underlying cause and you will want to be properly diagnosed. Your doctor will help treat the problem or may refer you to a sleep specialist.
