Question: Write a multi-choice question for the following article, with the given choices and answer: Article: In the summer of 1978 an English man named Steven was driving his tractor through a field of wheat when he discovered something strange. Some of his wheat was lying on the ground. The flattened wheat formed a circle about six meters across . Around this circle were four smaller circles of flattened wheat. Three years later a farmer who lived nearby discovered almost the same circles in one of his fields. These circles were larger--nearly 15 meters across . That same year , another English farmer discovered three circles of flattened wheat on his land--one large circle between two small circles. During the following years, farmers in England found circles in their fields more and more often. The circles are called "crop circles" because they usually appear in fields of wheat or corn. The wheat in the circles lies on the ground but is never broken; it keeps on growing, and the farmers can later harvest it. Farmers always discover the crop circles in the morning, so the circles probably form at night. They appear only in the months from May to September. What causes the crop circles? At first, people thought that some kids were making them as a joke, or that farmers were making them to attract tourists.(In fact, in 1991, two men said they made the circles themselves, but many scientists don't believe them.) People tried to copy them: They tried to make circles exactly like the ones the farmers had found. They couldn't do it. They couldn't enter a field of wheat without leaving tracks, and they couldn't flatten the wheat without breaking it. Several times people reported seeing stranger objects near the fields where crop circles later appeared. Many people believe that these crop circles are the messages sent by living things from outer space or the marks left by their spaceships. Scientists who have studied the crop circles try to find out what causes them. In the summer of 1990 some scientists spent three weeks in the part of England where many circles have appeared. They had all the latest high-tech equipment... Options: A that is done by living things from outer space B that cannot be solved but found all around the world C that cannot be made clear or understood D that is discovered and copied by the farmers Answer: C that cannot be made clear or understood Question:
Answer: The passage is mainly about something _ .

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: At present, too much carbon dioxide makes the earth warmer and warmer and causes terrible effect to human beings. To save our planet, to save ourselves, a new lifestyle called low-carbon life becomes popular. Low carbon means low energy and no waste. It is necessary for everybody to learn to live a low-carbon life. To live a low-carbon life, we'd better save energy as possible. Turn off the lights and TV whenever they are not needed. If possible, use cold water to wash clothes or dishes. Take a short shower and try to take a cold one when the weather gets warm. Don't do the cooking with electricity. To live a low-carbon life, we should eat less meat. Everybody knows eating too much meat makes people fat and easy to have heart disease, but maybe you don't know keeping animals for food produces even more carbon dioxide than all the cars in the world, and being a vegetarian can help reduce one and a half tons of carbon dioxide a year. Maybe _ is a little difficult, but it's really necessary. To live a low-carbon life, we are supposed to do less shopping. When we go shopping, we may drive a car or take other transportations. On the one hand, these machines pollute the air and waste energy. On the other hand, most of us always buy some useless things because of some advertisements. It is not only a waste of money but also causes trouble to the earth, because as you know, making everything will produce carbon dioxide more or less. There are many other ways to live low-carbon life, such as recycling things, planting trees and reusing textbooks. If we can keep it a habit in our daily life, the earth will become a safer planet for us to live on. ,. Options: A wasting money causes trouble to people B the advertisements are sometimes misleading C the less you shop, the less carbon dioxide will be produced D some of the things you bought are useless Answer: C the less you shop, the less carbon dioxide will be produced Question:
Answer:
We should do less shopping because _ .
