Article: When my daughter was in the fifth grade, she came home from school almost every night with three or more hours of homework. It was my duty to help her get it done. One night she worked until midnight doing her homework. I felt annoyed, but I didn't want the teacher to think I was lazy. So I never complained. I wasn't sure, but it seemed to me that five hours of homework was a bit too much for a fifth grade student. Later, I found out that parents and educators have discussed about homework for more than a century. Parents who like more homework want to give their children every advantage to succeed in today's world. Some educators see homework as a way to help students perform better in tests. Other parents dislike the recent trend toward more homework. They don't want to stay up until midnight helping their children. They would prefer to spend their time going to the park or reading some really good books with their children. Added to the opposition are those who say that homework increases the gap between the rich and the poor. That's because middle class families do better when it comes to helping their children with their homework. So, who is right? Is homework an enemy or a help? According to experts, the truth lies somewhere in the middle. Question: The author never complained to the teacher because _ . Yes or no, is the answer "she was afraid of being thought lazy by the teacher."?
No

Article: Looking for a new weight loss plan? Try living on the top of a mountain.Mountain air contains less oxygen than air at lower altitudes,so breathing it causes the heart to beat faster and the body to burn more energy. Studies have found that athletes training at high altitudes tend to lose weight.Doctor Florian Lippl in Germany wondered how the mountain air would affect _ individuals if they weren't doing any more physical activity than usual. Lippl and his colleagues invited 20 obese men to an environmental research station about 300 meters below the summit of Zugspitze, mountain around 2, meters near the Austrian border.2,970 This was no hiking expedition. They were allowed to eat as much as they liked. men also gave The blood so that researchers could test for hormones linked to appetite and obesity.At the end of the week, men, the whose weight starting out was 105 kilograms, had lost about 1.5 kg on average.The men's blood pressure also dropped,which the researchers owed to weight lost. Exactly what caused the weight loss is uncertain.Loss of appetite is common at higher altitudes, and indeed the men ate significantly less than usua!--about 700 calories fewer per day. Appetite loss at high altitudes could certainly be key,notes Damian Bailey,a physiologist, who himself recently lost 11 kg during a 3-month expedition to the Andes in Chile. Unfortunately,for the average person there's no treatment that can resemble living at high altitudes, says Lippl.He says,half-jokingly, obese people plan their holidays,they might not "If go to the sea,but maybe to the mountains." Question: Why does Damian Bailey agree with the idea of appetite loss at high altitudes? Yes or no, is the answer "He lost much weight in the high altitude Andes."?
No

Q: Article: After the coming of Europeans to the Americas, Indians were forced to change their way of life. Yet the influence of Native American culture is still felt throughout the United States. Many of the foods commonly eaten in the United States today were first grown by American Indians. Among these foods are corn, white and sweet potatoes, peanuts, pumpkins, tomatoes, and certain beans and berries. Native Americans also discovered ways to use herbs and other plants as medicines. Native American inventions, such as canoes, ponchos and parkas ,hammocks and snowshoes are still in use today. Other marks of Indian culture were left in American place names. The state of Alaska, for example, takes its name from a Native American word meaning "great land". Today nearly 1.5 million Native Americans live in the United States. Some still preserve the ways of their ancestors, speaking Indian languages and keeping alive their legends, art forms, and customs. Other Native Americans keep few of the old ways, but remain proud of their people's contributions to American history. Americans have come to appreciate the beauty of Indian crafts . Many artists find _ in traditional Indian designs. Many Indian values, too, have become widely held. Americans today believe that the land, air and water are precious resources that must be carefully protected. As one government official wrote recently: We have slowly come back to some of the truths that the Indians knew from the beginning. People need to learn from nature, to keep an ear to the earth, and to refill their spirits in frequent contacts with animals and wild land. Question: What does "Native Americans" refer to in the passage? Yes or no, is the answer "American Indians."?
A: No

Article: Everyone has an ambition to travel. But those who cannot do so themselves might find it interesting to work in a travel agency, arranging journeys for other people. Brian Lawtey does this, working in a small travel agency in an industrial city. Most of his work is concerned with holiday, both at home and abroad. Every autumn, the agency sends out hundreds of booklets full of attractive, color1ed photographs, describing the holidays that their customers will be able to have the next year. Soon, people begin to come into the office to book their holidays: perhaps a week's skiing in prefix = st1 /Austriain January, perhaps a cruise to the Caribbean in February, perhaps a seaside holiday inSpainin May, or a tour of Africa. Brian often has to advise people on what holidays will be suitable for them, and they always have a lot of questions. Last year, for example, a lady of eighty-two wanted to book for a mountaineering holiday in the Alps, and Brian had great difficulty in persuading her that it would not be suitable. In the end, she decided to go for a Mediterranean cruise instead. Arranging journeys for people who have to travel abroad on business is often very complicated, but Brian enjoys this work. For example, last spring Mr. Perry,a director of chemical firm, went on a business trip, and Brian arranged it all for him. First, Mr. Perry traveled to Londonby trainband stayed overnight in a hotel near the airport, because his plane left early the next morning. He flew to Frankfurt inGermany, where he spent the morning discussing business. Then he went on by train toZurich, where he stayed the night. After a meeting the next morning, he caught a plane for Tokyo, and spent three days there before going toAmerica. He had business in Seattle, Chicago andNew York, and stayed some time in each of those places. From New York, he flew back toLondon,and then got home by train. The next day he telephoned the agency to thank Brian for arranging everything so well for him. Question: Mr Perry telephoned the agency to thank Brian because _ .
