Problem: Write a multi-choice question for the following article: Article: Back in the 1860s, a British scientist named Henry Walter Bates noticed something interesting in the animal world: a kind of butterfly, Common Mormon, can change the pattern on its wings so that it looks like another butterfly species, the Common Rose, which is poisonous for birds to eat. Bates argued that animals develop this ability to protect themselves from being eaten. This theory had been widely accepted by scientists. But one question remains: how do these animals manage to do that? After more than 150 years, scientists are finally able to answer that question--it is all down to a gene called "doublesex", according to a study published on March 6 in the journalNature. In fact, scientists have long known that genes are responsible for this useful ability. But until the new study, scientists hadn't been able to find out which genes in particular were responsible. Scientists at the University of Chicago compared the genetic structures of the Common Mormons that changed their wing patterns with those of ones that did not. And all the results pointed to a single gene, "doublesex". This was much to the scientists' surprise. They used to expect that something as complex as this would be controlled by many different genes. For example, one gene would control the color of the upper part of the wing, one would do so for the lower part. However, the "doublesex" gene doesn't quite do everything by itself. Instead, it acts like a switch--it "tells" other genes to change the wing patterns. Isn't that clever? Scientists believe that this special ability of the "doublesex" gene on Common Mormon was developed throughout the long history of evolution. "The harmless species gains an advantage by resembling something predators avoid," Sean Carroll, a scientist toldNature. "it was obvious evidence for natural selection. "

A: Question: What is the best title of this passage?Options:A How Common Mormons stay safeB How butterflies changed wings' patternC What American scientists discoveredD What genetic structures of butterflies haveAnswer:A

Problem: Write a multi-choice question for the following article: Article: If you are lost in the mountains, stay calm in the face of darkness, loneliness, and the unknown. It will greatly increase your chances of survival. Many people think that preparing necessary equipment and knowing how to use it are very important, but in fact eighty percent of mountain survival is your reaction to fear. Finding a hiding place Unnecessary labor will make you sweat and make you cold. Find a hiding place around you before trying to start your own construction. If you are in a snow-covered area, you may be able to dig a cave in deep snow for protection from the wind. You should try to hide yourself in the middle of the mountain if possible. Stay out of the valleys--- cold air falls, and the valley floor can be the coldest area on the mountain. Signal rescuers for help The best time to signal rescuers is during the day. Signal for help from the highest point possible--- it will be easier for rescuers to see you, and any sound you make will travel farther. If you take a box of matches and a space blanket ( a special blanket for traveling ), build three smoky fires and put your blanket ---gold side facing out --- on the ground. Do not walk away It will make finding you more difficult , as search teams will be trying to follow your path and may miss you if you have gone off in a different direction. Searchers often end up finding a car with no one in it. If you get frostbitten , do not rewarm the affected area until you are out of danger. You can walk on frostbitten feet, but once you warm the area and can feel the pain, you will not want to walk anywhere. Try to protect the frostbitten area and keep it dry until you are rescued.

A: Question: According to the passage, people most probably fail to survive if they _Options:A do not take enough equipmentB stay in the middle of the mountainC do not keep themselves warmD stay in a snow-covered areaAnswer:C

Problem: Write a multi-choice question for the following article: Article: Among rich countries , people in the United States work the longest hours. They work much longer than in Europe. This difference is quite surprising because productivity per hour worked is the same in the United States as it is in France, Spain and Germany, and it is growing at a similar speed. In most countries and at most times in history, as people have become richer they have chosen to work less. In other words they have decided to "spend"a part of their extra income on a fuller personal life. Over the last fifty years Europeans have continued this pattern, and hours of work have fallen sharply. But not in the United States. We do not fully know why this is. One reason may be more satisfying work,or less satisfying personal lives. Longer hours do of course increase the GDP . So the United States has produced more per worker than, say,France.The United States also has more of its people at work,while in France many more mothers and older workers have decided to stay at home.The overall result is that American GDP per head is 40% higher than in France,even though productivity per hour worked is the same. It is not clear which of the two situations is better.As we have seen, work has to be compared with other values like family life, _ often get lost in interest.It is too early to explain the different trends in happiness over time in different countries. But it is a disappointing idea that in the United States happiness has made no progress since 1975, while it has risen in Europe. Could this have anything to do with trends in the work-life balance ?

A: Question: From the text we know that the author _ .Options:A believes that longer working hours is betterB prefers shorter working hours to longer onesC says nothing certain about which pattern is betterD thinks neither of the patterns is goodAnswer:C

Problem: Write a multi-choice question for the following article: Article: When Steve Maxwell graduated from college, he had an engineering degree and a high tech job -- but he couldn't balance his checkbook. "I took one finance class in college but dropped it to go on a ski trip," says the 45-year-old father of three, who lives in Windsor, Colorado. "I actually had to go to my bank and ask them to teach me how to read my statement." One of the biggest obstacles to making money is not understanding it: Thousands of us avoid investing because we just don't get it. But to make money, you must be financially literate. "It bothered me that I didn't understand this stuff," says Steve, "so I read books and magazines about money management and investing, and I asked every financial whiz I knew to explain things to me." He and his wife started applying the lessons: They made a point to _ . They never bought on impulse, always negotiated better deals (on their cars,cable bills, furniture) and stayed in their home long after they went for an expensive vacation. They also put 20 percent of their annual salary into investments. Within ten years, they were millionaires, and people were coming to Steve for advice. "Someone would say, 'I need to refinance my house -- what should I do? 'A lot of times, I wouldn't know the answer, but I'd go to find it and learn something in the process," he says. In 2003, Steve quit his job to become part owner of a company that holds personal finance seminars for employees of corporations like Wal Mart. He also started going to real estate investment seminars, and it's paid off: He now owns $ 30 million worth of investment properties, including apartment complexes, a shopping mall and a quarry. "I was an engineer who never thought this life was possible, but all it truly takes is a little self education," says Steve. "You can do anything once you understand the basics."
