题目内容

Recently, some concerns have been raised about the health of the world's banana plants. Many media reports have said that bananas may completely disappear in the coming ten years.

Bananas are one of the world's most important food crops. They are also the fourth most valuable export. Bananas do not grow from seeds. Instead, they grow from existing plants. Bananas are threatened by disease because all the plants on a farm are copies of each other. They all share the same genetic weaknesses.

For example, the Cavendish banana is most popular in American markets. It is an important export crop. However, some kinds of fungus (真菌) organisms easily infect the Cavendish. Black Sigatoka disease affects the leaves of Cavendish banana plants. The disease is controlled on large farms by putting chemicals on the plant's leaves. Farmers put anti-fungal chemicals on their crops up to once a week.

Another fungal disease is more serious. Panama disease attacks the roots of the banana plant. There is no chemical treatment for this disease. Infected plants must be destroyed. Panama disease has affected crops in Southeast Asia, Australia and South Africa. There is concern that it may spread to bananas grown in the Americas. This could threaten an important export product for Central and South America.

The International Network for the Improvement of Banana and Plantain, whose headquarter lies in France, supports research on bananas. The group says that more research must be done to develop improved kinds of bananas.

The group says that fungal diseases mainly affect only one kind of banana. In fact, there are five-hundred different kinds of bananas. The United Nations Food and Agriculture Organization says the Cavendish banana represents only ten percent of world production.

The UN agency says farmers should grow different kinds of bananas. This protects against diseases that affect only one kind. Experts warn that disease may cause the Cavendish banana to disappear. This has already happened to one popular banana because of its genetic weakness against disease. (words: 335)

I believe that families are not only blood relatives, but sometimes people who show up and love you when no one else will.
In May 1977, I was living in a Howard Johnson’s motel off Interstate 10 in Houston. My dad and I  1  a room with two double beds and the bathroom was too 2  for a 15-year-old girl and her father.

Sometimes, people are required to fill in personal information when they register online, which may lead to some unexpected trouble. Recently, the BBC is reporting that a 17-year-old girl in Australia posted a(n) 【小题1】  of her grandmother at home counting a large sum of cash that she  【小题2】  hidden in the house. Just eight hours later, two armed men  【小题3】  the girl’s house. They demanded to speak to her to find out where the grandmother’s house was,   【小题4】  they could get the money they had seen.   【小题5】 , the girl was not home at the time, so the robbers 【小题6】 a small amount of cash from the mother and left.
Because the 【小题7】 is still under investigation(调查), local police aren’t saying 【小题8】 else about it. It’s not known yet whether the girl had used privacy setting on the Facebook profile page, and even whether the robbers 【小题9】 the girl in the past.
Two other 【小题10】 were at home then, a 58-year-old man and a 14-year-old boy, the girl’s father and brother. Luckily, no one was 【小题11】 . The robbers left peacefully after  【小题12】  that the girl was not home and that no one else there knew anything about the  【小题13】  that had appeared in the photo.
Police in both Britain and Australia are using the case to 【小题14】  citizens of the dangers of posting personal information on social networks and to suggest users of websites  【小题15】   doing so. The police say it is  【小题16】  that the girl posted a comment in the past that gave clues to the address,    【小题17】  that the robbers knew the girl in another way.    【小题18】  , they suggest, a posting by a friend on their site could have   【小题19】  such information. To find it, the robbers would only have had to search for those posting on other pages that  【小题20】  the girl’s name.

My 4-year-old son now enjoys posting letters. He has formed the   36  of drawing pictures, writing his name on them, and then    37  the artwork in an envelope. He then insists on   38  his handwork to the neighbors, and a mail box he   39  belongs to the elderly couple who live next door. To be   40  , I didn’t think much of it, but I had   41  to warn my neighbors of the drawings   42  appearing in their letterboxes—I just didn’t have the   43  to do so, because I was a little busy recently.
On Tuesday of last week, I was walking down to school to collect my son when I   44  Mary, my elderly neighbor,   45  at her mail box. She said, “Jodie, is it your little son that has been posting items in my letterbox to me?” I was at once   46 , “Oh yes, Mary, it is. I’m sorry. I meant to tell you…” She cut me off, “Jodie, I just love his mail. I’ve   47  every item he has sent. You don’t know how much   48  the letters has made my day. I just love them.” While I was walking down to school after our   49 , many thoughts came to me. Mary doesn’t have a lot to fill her days,   50  she was a mother to a number of children herself who receives fairly regular visitors. The small   51  of getting some mail—pictures drawn by the hand of a young child—has brought   52  to her days, just as my visit to my grandparents does.
I have decided that my son should   53  this practice. He should also start sending some items to his grandparents in Perth as well. It will most   54  make their day.
It’s doing the little, simple things that can often make a big   55  in someone’s life.

China has become Volvo's third largest market, with more of its car models to go on sale in the world's largest auto(汽车) market this year, Chief Executive Office (CEO) of Volvo Cars China said in Tianjin.
Alexander Klose, CEO of Volvo Cars China, told Xinhua at the Ninth Tianjin International Automobile Trade Show, being held from Friday to Wednesday.
Klose said Volvo Cars had entered a new time of fast development, adding that its sales volume in China roared in 2010.
Up to the end of September, Volvo's global sales volume was up 12.5 percent year on year(同年比), compared with 52 percent year-on-year rise in China, he said.
Two new Volvo sales centers opened in Beijing within merely one week in early October, about two months after east China's ZhejiangGeely Holding Group Co acquired(购得)the Swedish brand from the US auto giant Ford for $1.5 billion in early August.
Klose said he was confident of seeing tremendous(巨大的) growth in China's auto market in the next five years. "As the Chinese government has increased the tax rate for large displacement (排量)cars already, we now have a lot of cars below three liters(升), and I think we'll stick to that strategy, as you can see now the XC60 which was introduced today is just two liters," he said.
"As the technology advances, we'll probably even see 1.6 liter engines or 1.5 liter engines in the future," he added.
Volvo Cars is not the only automaker hoping to take advantage of China's rapidly growing auto market.
Bentley, the famous British luxury(豪华) carmaker, will open a new sales center in China at Tianjin Thursday, which is the 11th one in China, according to a press release(新闻发布) by Shanghai-based Zenith Integrated Communications Corp (Zenith) Saturday at the auto show.
Zenth is the public relations agent of Bentley in China. The automaker has sold 421 limousines(大型豪华轿车) to China in 2009, and the goal for 2010 is 777, the release said.
【小题1】The word underlined in the third paragraph would probably be___.      

A.shouted loudlyB.increased in large numbers
C.reduced rapidlyD.burned brightly
【小题2】From this passage we can infer that ___.                       
A.The Ninth Tianjin International Automobile Trade Show was held from Friday to Wednesday.
B.Volvo Cars is a world-famous carmaker in Britain.
C.Of all the auto sales volume Volvo sales volume is only number one in China
D.Volvo sales centers are developing very fast in China recently
【小题3】The text is mainly about____.                       
A.China Becomes Volvo's 3rd largest market
B.Volvo Cars in China
C.Volvo Sales Volume in China
D.Carmakers in China
【小题4】How many carmakers are mentioned in this passage which opened and will open new sales centers in China recently?
