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 apart.
"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. 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. |
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 |
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 |
What can be inferred from the last paragraph?
A.Western scientists’ doubt is unreasonable. |
B.Westem 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. |

Country-dwellers(农村居民) often say the constant noise, heavy traffic and crowds of the city would drive them mad. Well, they might be right, according to the latest research. City residents are more likely to develop mental illnesses than those who live in villages, a study has found.
Researchers from Cardiff university examined the lifestyles of more than 200,000 people in Sweden and found that those who lived in urban areas were more at risk from mental illnesses than people who lived in villages.
The experts don’t know exactly why this is but they suggest that town and city residents are more likely to be ostracized(排挤) by those around them. They are more likely to experience discrimination(歧视) if they do not fit in, which can lead to them feeling anxious and even developing mental illnesses.
Dr Stanley Zammit, who led the research said that people living in towns and cities are more likely to develop other mental illnesses that result in personality changes — a condition known as non-affective psychosis(非情感性精神病).
Earlier this year an official report found that village-dwellers live an average of two years longer than those living in towns and cities. According to figures from the Office of National Statistics in the UK, men who live in villages are likely to live for between 78 and 79 years, while those in towns and cities can expect to survive to an age of 76. Women on average survive to their 81st birthday in towns and cities, but live to between 82 and 83 in villages. The small marked town of Wimborne Minster in rural Dorset was named the healthiest place to live in.What is the passage mainly about?
A.Country-dwellers are more likely to develop mental illnesses. |
B.City-dwellers are more likely to develop mental illnesses. |
C.Country-dwellers live longer than city-dwellers. |

When Julio Diaz stepped off the subway after work one night, he was simply planning to go to his favorite local diner for a meal. But when a teenage boy approached him with a knife, Diaz knew the evening was about to take a more dramatic(巨大而突然的) turn.
The young man demanded Diaz’s wallet, and Diaz passed it over without objection(异议). But just as he turned to walk away, Diaz called, “Hey, wait a minute. You forgot something.”
The young man turned around, surprised.
“If you’re going to rob people for the rest of the night, you might as well take my coat to keep warm.”
The teenager looked at Diaz in disbelief, and asked why he would do such a thing. Diaz replied, “If you’re willing to risk your freedom for a few dollars, I guess you must really need the money.”He said he was heading out for dinner, and that he would be happy to take someone with him.
The young man decided to take Diaz up on his offer. As they were sitting at the table, the manager, dishwashers and waiters all stopped over to say hello to Diaz, and the young man was amazed at his popularity.
“Haven’t you been taught that you should be nice to everybody?”Diaz asked him.
“Yeah, but I didn’t think people actually behaved that way,” the teenager replied. Thanks to Diaz, he was beginning to see that kindness wasn’t so strange, after all.
When the bill came, Diaz told the teen that he’d have to get the check. After all, he still had Diaz’s wallet.
But the teenager put the wallet on the table without a moment’s thought, and Diaz treated him to dinner. Diaz also gave the would-be robber a $20 bill — in exchange for his knife. “I figure, you know, if you treat people right, you can only hope that they treat you right,” Diaz said.When a teenage boy approached him with a knife, Diaz was on his way ________.

I live in Hollywood. You may think people in such an attractive, fun-filled place are happier than others. If so, you have some mistaken ideas about the nature of happiness.
Many intelligent people still equate happiness with fun. The truth is that fun and happiness have little or nothing in common. Fun is what we experience during an act. Happiness is what we experience after an act. It is a deeper, more long-lasting emotion. Going to an amusement park or ball game, watching a movie or television, are fun activities that help us relax, temporarily forget our problems and maybe even laugh. But they do not bring happiness, because their positive effects end when the fun ends.
I have often thought that if Hollywood stars have a role to play, it is to teach us that happiness has nothing to do with fun. These rich, beautiful individuals have constant access to exciting parties, fancy cars, expensive homes, everything that spells “happiness”. But in memoir(回忆录) after memoir, celebrities reveal the unhappiness hidden beneath all their fun: depression, alcoholism, drug addiction, broken marriages, troubled children, and long-time loneliness.
The way people hold on to the belief that a fun-filled, pain-free life equates happiness actually decreases their chances of ever attaining real happiness. If fun and pleasure are equated with happiness, then pain must be equated with unhappiness. But, in fact, the opposite is true: More times than not, things that lead to happiness involve some pain.
As a result, many people avoid the very efforts that are the source of true happiness. They fear the pain inevitably brought by such things as marriage, raising children, professional achievement, religious commitment, charitable work and self-improvement.According to the passage, “fun activities” ____________.
A.are the things we do before we find happiness |
B.may help us relax and forget our problems sometimes |
C.will lead us to the true happiness |
D.could provide long-last positive effects |
In the author’s opinion, those Hollywood stars ____________.
A.possess happiness because they are rich and famous |
B.experience almost all kinds of happy things |
C.tell us happiness isn’t equal to fun using their own stories |
D.have to suffer a lot before they become successful |
It is difficult for people to find real happiness because ____________.
A.they believe happiness is the fun life without pain |
B.they find pain equals unhappiness |
C.they fear to lose what they already have in life |
D.They are afraid all their efforts were in vain |
The main purpose of the text is to ____________.
A.describe the difference between happiness and fun |
B.show the true meaning of happiness |
C.encourage people to pursue fun activities |
D.advise people to find their real life |
7 ways a government shutdown will affect your daily life
(CNN) -- Democrats and Republicans were unable to resolve (解决) their differences over Obamacare (奥巴马医改计划)and now the government is shut down. The two previous shutdowns — 1995 and early 1996 — cost the country $1.4 billion. But what will the shutdown mean for you? Here are 7 ways the government shutdown will affect you.
7. Vacation all I ever wanted: Need to get away? Well, you can’t. At least not to national parks. Or to national zoos. Or to national museums. They'll be closed. Were you thinking more along the lines of a trip to France? If you don’t already have a passport, you might not get your blue book in time. The last time the government shut down, 200,000 applications for passports went unprocessed.
6. If you drive a car, I'll tax the street: You may be thinking, “No functioning government, no need to pay taxes.” Think again. The Man would continue to collect taxes. U.S. bonds would still be issued. And other essential banking functions will go on.
5. Wait a minute, Mr. Postman: You know that whole “Neither snow, nor rain, nor heat, nor gloom of night” thing? Apparently, the U.S. Postal Service works through shutdowns as well. Sorry, you won’t catch a break from the junk mail.
4. I want a new drug: Oh, the irony (讽刺的). Republicans still want to defund, delay or otherwise withdraw gradually at Obamacare in exchange for funding the government. But the health care act at the center of this storm would continue its process during a shutdown. That is because its funds aren’t dependent on the congressional budget (预算) process.
3. Pass the ammunition (军火): Not so fast. A shutdown would affect the Bureau of Alcohol, Tobacco, Firearms and Explosives. Translation: That gun permit you wanted processed won’t happen anytime soon if this goes on for a while.
2. Money (that's what I want): Well, if you owned a small business and needed a loan from the government, you would have to wait, depending on how long this lasts. If you were planning to buy a house and needed a federal loan, you would have to wait.
1. I'm proud to be an American: Perhaps the biggest hit would be to the collective psyche (下意识心理). America is the largest economy in the world and a beacon for how democracy ought to work. A recent CNN Research Corporation found that 51% would blame Republicans for the shutdown. The United States has operated without a budget since 2009 and has avoided a government shutdown with last-minute deals. Not only did the government run out of money on Tuesday, but the nation is set to hit its borrowing limit and potentially default on its debt in mid-October. Together, they serve as a double whammy (打击).Which is the most probably meaning of the underlined word?
A.Raise some money. | B.Take the money back. |
C.Borrow some money. | D.went on a strike. |
When the government’s shut down, what can the Americans do?
A.Apply for a gun permit. | B.Apply for a new passport. |
C.Apply for a loan. | D.Pay taxes. |
How many times has the American government ever shut down so far?
A.Once. | B.Twice. | C.Three times. | D.Not mentioned. |
According to the essay, what led to the shutdown of the American government?
A.The government of America ran out of money. |
B.The government of America is on debts. |
C.America is set to hit the borrowing limit of its debts. |
D.The American government ran out of money and may fail in repaying its debts. |
