Article: You might think I'd have little in common with a camel, but we do share one useful skill: both of us can go for a very long time without water. Usually I start my day with a cup of tea, and then I might have a glass of water with my lunch and one with dinner, that's about a liter of liquid in 24 hours. It feels like plenty, but apparently it's not nearly enough. After years of suffering headaches and poor digestion I spoke to a neurologist about my regular headaches and a nutritionist about my poor digestion, and both told me I should be drinking up to three liters of liquid a day for my body to function at its best. I decided to conduct an experiment. What would happen if I drank the recommended amount every day for a month? The photograph of me taken the day I started this trial demonstrates perfectly and rather frighteningly what a lack of hydration does to a face. I am 42, but have to admit I look more like 52 in this picture, which is shocking. There are dark shadows under and around my eyes, which make me look exhausted, a profusion of wrinkles and strange reddish blotches, and my skin lacks any luster . It looks dead. Even my lips look shriveled . This is all classic evidence of poor hydration, apparently. Every system and function in our body depends on water. It flushes toxins from the vital organs, carries nutrients to cells, provides a moist environment for ear, nose and throat tissues, and eliminates waste. Not drinking enough means all these functions becomes damaged. So I decided to see how I would look and feel if I drank three liters of water every day for 28 days. The results were astonishing. Question: According to the passage, the author most probably tends to tell us _ . Yes or no, is the answer "drinking enough water is key to one's health"?
No

Article: Researchers questioned nearly 9,800 people over the age of 50 about their lives and found women were happier than men and enjoy life more in old age. Dr Elizabeth Breeze, one of the researchers, said that women could become happier as they get older as they no longer have to worry about looking after their families. She said:"There is a difference between the way men and women view their quality of life and they are influenced by slightly different things. Women are affected negatively by caring for someone else or if they are not in employment but if they see their children and family more they are positively affected." "A strange thing happens to male actors, especially movie stars, in my experience," said Helen Mirren, a 62-year-old Hollywood actress."A young male actor feels that all the girls want him-he's a star. As actors get older they bad-tempered for they have lost that sense of being in control of their destiny ." Wealth also helps you live longer with the poorest people more than twice as likely to die earlier than the richest, researchers at University College London discovered. In some age groups. the difference was even greater. The poorest women between 60 and 74 are six times more likely to have died than the richest women of the same age. According to the study, you have more chances of living longer if you are married, educated to certain degree or a professional. single people are twice as likely to die early as those who are married or living with a partner. Question: What may be the best title of the passage ? Yes or no, is the answer "Women Happier Than Men in Old Age."?
No

Q: Article: Don't you think your schoolbag is too heavy to bear? The e-schoolbag will free you from the weight. It is said that e-schoolbags are going to be brought into use in Chinese middle schools soon. An experiment with several hundred e-schoolbags will begin in seven cities: Beijing, Shanghai, Dalian, Shenzhen, Chongqing, Taiyuan and Shijiazhuang. And the e-schoolbags are going to cover all over China if the experiment proves to be successful. In fact, the e-schoolbag should perhaps be called an e-notebook. It is a small hand-held computer for school students. Heavy schoolbags have long been a serious problem for school students. The average schoolbag of middle school students weighs up to 5 kilos. But the e-schoolbag will change everything. It is much lighter than a usual schoolbag, weighing under 1 kilo. Also, it is no bigger than a usual book, but it can still hold all the things for study, such as a textbook, a notebook and exercise book. They could be made into chips that are as small as a stamp. The students can read the text page by page on the screen. They can still take notes using a special electronic pen. If they want to know the meaning or the pronunciation of a new word, or even e-mail their teachers, it's just a press of a button. In some foreign countries, it is becoming common. But it is hard to tell when people will receive this new form of study. Some say that e-textbooks can be easily broken, some say that it is not good to students' eyesight to look at the screen for long. But only time will tell. Question: The best title for the passage should be _ . Yes or no, is the answer "A New Invention, A New Schoolbag"?
A: Yes

Article: It is 4 o'clock in the early morning. Everything but the computing room on the campus of the university appears as quiet and misty as the mysterious hell. In the computing room, 30 students with sleepy eyes, sit still at their desk, beating the dirty and worn keys. Staring at the colorful screen, they tap continuously for hours. For the other parts in the world, it might be in the middle of the night, nevertheless here time represents nothing. It is an entirely enclosed field. These young computer "hackers" are tracing a sort of stimulus , a drive so exciting and absorbing that it ignores nearly anything else in their lives and becomes the focus of their being. They are addicted computer programmers. Some of these students have been glued to the console for no less than twenty hours even with no break for meals or rest. Some have been sleeping on sofas and chairs in the computing room, trying to struggle for a few moments' rest but hating to get too far away from their addicted machines. It is not necessary for most of these students to be at the computing room in the middle of the night. What they are working belong to no assignments. They remain there because they desire to be -- they can not resist the attraction of the computers. Furthermore, they are in groups instead of being alone. There are hackers at computing rooms all over the country. In the unimaginable way, they focus on nothing but computer. They escape from schooling and live beyond friendship; they might have difficulty being employed, choosing to travel from one computing room to another. They may even give up personal health. "There is one hacker in my memory. We actually had to lift him away from his chair to feed him and arrange him to rest and sleep. We truly worried about his health," says a computing science professor at California University. Professors of computer science are nowadays paying more attention to this hacker phenomenon and are on the watch for future hackers and more and more severe computer addicts. They believe... Question: Which of the following is NOT true of those young computer "hackers"? Yes or no, is the answer "Most of them are top students majoring in computer programming."?
No
