Question: [Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: 2010 was a good year for American farmers. They earned about eighty-two billion dollars. That is almost one-third more than that they earned last year. And it is twenty-six percent higher than the ten-year average. Values for grain and oilseed crops are up about three percent from last year. The value of animal production is up by almost seven percent. In 2011, farm exports are expected to break the all-time high set in 2008.The Agriculture Department says exports in 2011 could top one hundred and twenty-six billion dollars. The largest buyer of agricultural products is expected to be Canada. But farm exports to China are predicted to come within five hundred million dollars of Canadian purchases. Secretary Vilsack says countries in Southeast Asia and the Middle East are also buying more from American farmers. Poor growing conditions overseas played an important part in higher prices for American crops in 2010.Charlotte Hebe brand is chief executive of the International Food and Agricultural Trade Policy Council in Washington. She said drought conditions had a big effect over the summer. She said,"There were horrible weather problems, not just in Russia but also in some of the other former Soviet Union countries." Wheat prices rose after Russia stopped wheat exports,although Russia later eased the ban ."Wheat used to be America's top crop. What's interesting,though,is that wheat production has actually become less over the past few years because corn has become the most popular crop,"said economist Charlotte Hebebrand. Corn is mostly fed to animals. But Miss Hebebrand said with the recent increase in wheat prices, American farmers might plant more wheat again. Corn and wheat are the two largest crops supported by the government. Options: A planted less corn B planted morn crops C planted morn wheat D earned more money Answer: D earned more money Question:

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: Advice to "sleep on it" could be well founded, scientists say. After a good night's sleep a problem that couldn't be solved the night before can often appear more manageable. Researchers at the University of Luebek in Germany have designed an experiment that shows a good night's sleep can improve insight and problem-solving ability. "If you have some newly-got memories in your brain, sleep acts on these memories and restructures them, so that after sleep the insight increases," said Dr Jan Born, a neuroscientist, at the University. To test the discovery, they taught volunteers two simple rules to help them turn a string of numbers into a new order. There was also a third, hidden rule, which could help them increase their speed in solving the problem. The researchers divided the volunteers into two groups: half were allowed to sleep after the training while the rest were forced to stay awake. Dr Jan Born and his team noticed that the group that had slept after the training were twice as likely to figure out the third rule as the other group. "Sleep helped," Born said in a telephone interview . The important thing is that you have to have a memory description of the problem you want to solve in your brain and then you sleep, so it can act on the problem." But Born admitted that he and his team don't know how restructuring of memories occurs or what controls it. Pierre Maquet and Perrine Ruby of the University of Liege in Belgium said the experimental evidence supports the suggestion that sleep can help develop creative thinking. Although the role of sleep in human creativity will still be a mystery, the research gives people good reasons to fully respect their periods of sleep, they added. Options: A To test problem-solving ability in sleep. B To discover people's insight during sleep. C To prove a good sleep helps solve problems. D To discuss how to improve sleeping quality. Answer: C To prove a good sleep helps solve problems. Question:

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: A spirit of adventure, curiosity about different cultures and the desire for a challenge can be found in young people everywhere. More and more students inprefix = st1 /Chinaare backpacking around the country.     According to the China Youth Travel Service, Hainan, Dalian, Zhangjiajie andQingdaowere among the most popular spots for young Chinese backpackers last year. Backpacking allows the traveler a greater sense of independence.      "I can no longer put up with the instructions of a tourist guide," said Huang Ye, a 19-year-old college student inBeijing. "They are always driving you to places that you do not want to go to and trying to make you buy local souvenirs."       Huang likes to travel as a backpacker. She prefers an independent trip that she took with two friends to Jiuzhaigou inSichuanProvince. There, they chose some scenic spots to visit and avoided the masses of   tourists.            Backpackers see the difficulties of such travel as a challenge. Living on bread and water for days on end, wearing the same clothes over and over again and carrying a heavy bag on their backs while climbing a mountain are all character-building experiences.        But perhaps the greatest challenge that a backpacker faces is not a physical one, but mental. They may face loneliness if they travel alone.     Chen Xuewei, 21, suffered when he took off aroundChinalast year."I felt very lonely at the beginning of my journey. A walkman didn't make me feel better, but rather heightened the sense of loneliness I felt. I even called up my friends to tell them that I wanted to give up and go back toBeijing," he recalled. But he kept going. He started to make friends and appreciate the local customs. He took lots of photos to record his trip and now he is glad he stuck it out.     Backpackers generally find themselves to be mature after their experiences. "Their travel logs   track their development as people." "When I feel  _ , I read my travel log again," said Tang Weifeng, a postgraduate atPekingUniversity. "By reading... Options: A Some backpackers' experiences. B The advantages of backpacking. C Young people's love of backpacking. D The increasing popularity of backpacking amongChinese students and its reasons.

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: Baby sign language is a growing movement. Pointing to a color1ful flower, Campbell lifts her baby's soft hand, and rapidly moves it from one side of his nose to the other as she sniffs  ."Flower!" she says loudly. Gregory smiles and looks carefully. It could be a year before Gregory, 4 months old, can speak, but now his mother hopes to communicate with her baby through sign language. Like others around the world, Campbell is part of a growing movement of parents teaching hearing babies simple signs to communicate before they can talk. The baby sign language has been more popular in recent years. The movie,"Meet the Fockers",where the main character teaches his young grandson to sign, makes it well developed. Babies generally begin to talk between 12 and 15 months, but babies can use sign language to communicate before they learn how to speak. "We know they are learning language faster than they are able to show you with their speech production because that system takes a long time to develop." says McRoberts, director of developmental research at the Haskins Laboratories. "They are understanding words before they are able to say them. From around 16 to 18 months, they might say 50 words but understand 200.They understand short sentences well." says McRoberts. Studies have shown deaf children learn to use sign language earlier than hearing children learn to speak meaningfully. As to whether hearing babies can communicate earlier with sign language, McRoberts says,"I think that's still unknown. It may not. I'm very interested in that very question." Options: A communicate with their babies B make their babies learn English fast C make their babies clever D make their babies interested in language Answer: A communicate with their babies Question:
