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

Ray Travers sat back at the large desk, and looked around his plush（豪华的）office．He was tired．

Ray's eyes stopped at a painting on the wall．It was a gift given by an old friend, Bull, as a farewell gift when he left his hometown．He recalled the life spent in that small town; pleasant times．The many hours he spent talking lo his good friend, and the tales he was told about hunting in the Africa of old．

Memories flowed back more than ten years; he remembered how he enjoyed hearing about the wonderful hunting, and how he wished he could have shared those times．

Ray opened his desk drawer and brought out a wooden box．He opened the lid and exposed a work of art, a hand-made hunting knife．This was a gift from Bull, given to Ray more than 20 years ago．It was one of the first knives Bull had made, and Ray had called it "Zambezi”, the river where Bull had been so many times．

He closed the box and sat upright at his desk; he was driving himself hard, and deserved a break．Things were going well with the business, everything running smoothly．He could afford a week off!

He went back home．A week in the hometown would be like going back in history．"Man, it's going to be good," Ray said aloud, as he turned onto the highway and watched the city lights fast disappearing, as he looked in the rearview mirror．

It was well into the night when Ray pulled into an all-night gas station He walked around the gas station and the memories started …  He was finally back on the road, the powerful car going its way through the night, headlights piercing （穿透） the darkness．Memories danced through the man' s mind．Memories of good times , when he knew what it was to relax , to talk, and to really visit．

Slowly entering town he looked around．Ray sat in his car, looking at the old building, smiling． Inside it was almost as though it was the same people as 15 years ago．

Robert Frost was one of America’s best known and most honored serious writers. But his fame came late in his life.
He was born in San Francisco, California in 1874. He lived in California during his early childhood. He was named after the chief Southern general in America’s Civil War. The general’s name was Robert Edward Lee. The poet was named Robert Lee Frost, because his father wanted to honor the general.
Someone once asked another American writer, Ernest Hemingway, how to become a writer. The best thing, he said, was to have an unhappy childhood. If this is true, Robert Frost’s childhood was unhappy enough to make him a very good writer. Robert Frost’s father was a reporter who wanted to be a politician. He often drank too much wine and became angry. Robert was the victim of his anger.
Robert Frost finished high school in 1891. After high school, Robert’s grandfather offered to pay his costs at Dartmouth College. But Robert left the school after a few months. He did not like it. He spent the next few years working at different jobs. At one time, he worked in a factory. Later, he repaired shoes. He was a teacher. He was a reporter. Always, he wrote poetry.
Robert Frost attended Harvard University for two years. After that, he returned to the many jobs he held before. For a while, Frost tried to take care of a farm in the state of New Hampshire. He was not a successful farmer. And he continued to write poetry. He said that until 1930, he earned only about ten dollars a year from writing.
In 1912, he decided to try to make a new start. He took his family to Britain. The cost of living was low. In Britain, Frost found a publisher for his first book of poems. The book was called A Boy’s Will. When it appeared in 1913, Frost received high praise from British readers. Praise was something he had not received in his own country.
Ezra Pound, another American poet living in Britain, read the poems and liked them very much. He wrote a magazine article about Frost. He also helped get Frost’s second book of poems published in America. That book was called North of Boston.

The baby monkey is much more developed at birth than the human baby. Almost from the moment it is born, the baby monkey can move around and hold tightly to its mother. During the first few days of its life the baby will approach and hold onto almost any large, warm, and soft object in its environment, particularly if that object also gives it milk. After a week or m, however, the baby monkey begins to avoid newcomers and focuses its attentions on “mother" 一 the real mother or the mother-substitute (母亲替代树).

During the first two weeks of its life warmth is perhaps the most important psychological (心理的) thing that a monkey mother has to give to its baby. The Harlows, a couple who are both psychologists, discovered this fact by offering baby monkeys a choice of two types of mother-substitutes 一 one covered with cloth 4nd one made of bare wire. If the two artificial mothers were both the same temperature, the little monkeys always preferred the cloth mother. However, if the wire model was heated, while the cloth model was cool, for the first two weeks after birth the baby monkeys picked the warm wire mother-substitutes as their fuvorites. Thereafter they switched and spent most of their time on the mw comfortable cloth mother.

Why is cloth preferable to bare wire? Something that the Harlows called contact (接級) comfort seems to be the answer, and a most powerful influence it is. Baby monkeys spend much of their time rubbing against their mothers' skins, putting themselves in as close contact with the parent as they can. Whenever the young animal is frightened, disturbed, or annoyed, it typically rushes to its mother and rubs itself against her body. Wire doesn't “rub" as well as does soft cloth. Prolonged (长时间的) “contact comfort" with a cloth mother appears to give the babies confidence and is much more rewarding to them than is cither warmth or milk.

According to the Harlows, the basic quality of baby’s love for its mother is trust. If the baby is put into an unfamiliar playroom without its mother, the baby ignores the toys no nutter how interesting they might be. It screams in terror and curls up into a furry little ball. If its cloth mother it now introduced into the playroom, the baby rushed to it and holds onto it for dear life. After a few minutes of contact comfort, it obviously begins to feel more secure. it then climbs down from the mother-substitute and begins to explore the toys, but often rushes back for a deep embrace (拥抱) as if to make sure that its mother is still there and that all is well. Bit by bit its fears of the new environment are gone and it spends more and more time playing with the toys and less and less time holding onto its “mother.”

A. Warmth.             B. Milk.                C. Contact.            D. Trust.

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．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．
