The Population Action International study gives several solutions to the water problem. One way, it says, is to find ways to use water for more than one purpose. Another way is to teach people to be careful not to waste water. A third way is to use less water of agriculture.

Dr. J. Robinson found out about the phenomenon of self-controlled pain almost by accident. He was studying the effects of analgesics used to control pain during childbirth and as part of the experiment made it possible for women having their child to press a button which gave an automatic injection—instead of having all injections made by the doctor. Afterwards these women did not say that they had less pain than other women in childbirth, but they did use considerable less of the drug. J. Atkins, a dental surgeon, has observed a similar phenomenon. As part of their efforts to make dentistry painless, Atkins and researchers at Aston University in Birmingham offered patients a switch they could flip to turn off the dentist's drill whenever they chose. But, after trying the switch on 50 patients Atkins gave up; none of the patients had ever flipped the switch. Perhaps the extra endurance was because the Aston team also use other methods to make dentistry painless. Apparently few other dentists are so considerate. The end result, according to the Birmingham survey, is that British people avoid going to the dentist, with the consequence that almost 30% of people in England and Wales have lost all their teeth, and more than seven out of ten have lost at least six teeth. Less than half of the public pay regular visits to the dentist. To find out why, Atkins and psychologist Cumberbatch interviewed a sample of patients attending a dental hospital. The most common reason people gave for not having dental check-ups were fear and pain. By using a little care and taking time to explain what will happen, Atkins feels, dentists could overcome these fears. There are techniques for giving injections without pain, and a "calm unhurried approach" to drilling can make that painless, too. Sadly, few dentists seem to take much trouble with their patients. "I am not nervous when I go to the dentist, and I do not have any pronounced sympathy for those who are, " said one dentist. "I tend to take the point of view that they are being unreasonable at my expense." The passage most possibly comes from______. A．a medical textbook B．a psychology textbook C．a popular magazine D．a serious magazine

David Salt is an expert on plants at Purdue University in West Lafayette, Indiana. He is working with plants that store large amounts of metals. In recent years, scientists have shown interest in using such plants to clean up harmful waste materials. Professor Salt says such plants also could be used to improve people's diets or even to create foods that fight cancer. Humans need a number of metals in their diets, including iron and zinc. These metals are needed in very small amounts, however. That is why they are called micronutrients. The lack of micronutrients is blamed for health problems in many developing countries. Children and pregnant women are mostly affected. Recently, Mr. Salt announced that he has identified and copied the genes from a kind of plant that stores metals in its tissues. He says his study suggests it may be possible to develop plants that contain minerals needed for good health. For example, the metal selenium is a strong anti-cancer agent. Some wild plants store selenium naturally. Mr. Salt says foods to fight cancer might be created if genes from these plants could be moved into crop plants. Locoweed, which is a common plant in the western U.S., stores selenium. Professor Salt says it may be possible to create cancer-fighting foods from it. He and scientists from a company called Unicycle Therapies have copied the gene that causes locoweed to take up selenium from the soil. Many people take pills to add important minerals or vitamins to their diet. However, Mister Salt notes that most selenium products sold in health food stores are of little use. That is because the human body can only take in and use selenium if it is in the right chemical form. The scientist says his team would like to develop a vegetable crop high in selenium. He wants to create an anti-cancer product in the foods we already eat. According to Pro. Salt, plants that take up large amounts of metal in their tissues can be used to ______. A．clean polluted soil and cure disease like cancer B．clean up harmful waste materials in soil and improve people's diet C．produce large number of micronutrients such as iron and zinc D．create food with important minerals or vitamins

Your house is not worth as much today as it was a few years ago because of the increased crime rate in your neighborhood. Perhaps your business is not doing as well as it used to because tourism is down due to increased terrorism in your part of the world. Crime, especially violent crime, has risen to a point where many people are afraid to walk al one in their own neighborhoods, afraid to open their door after dark, afraid to speak out and voice their own opinions. Some citizens have reacted by arming themselves with various weapons, legal and illegal, to defend themselves. Citizen groups have taken the law into their own hands by forming their own vigilante groups to administer judgment when they feel that their criminal justice system has not performed its duty. Experts argue whether the number of crimes committed is actually on the rise or whether there is simply a rise in the number of crimes reported. This issue is particularly true in cases of marriage violence, the abuse of spouse or children. Throughout much of history, cases of family violence and neglect often went unreported because of the attitude of society, which considered family matters to be private. Other experts argue about who is really to blame for criminal behavior. the individual or society. Researchers in the United States and Canada have identified several factors in society that contribute to the crime rate: massive urbanization, unemployment and poverty, and a large immigrant population. Other countries are more affected by factors such as politics, government corruption, and religion. (1)What does the passage mainly discuss？ A、Crime the widespread problem. B、The results caused by increasing violent crime. C、Factors contributing to the crime rate. D、Citizen groups combating crimes. (2)The word shoplifting in line 4 is closest in meaning to _____________. A、the crime of lifting the ban B、the crime of moving the shops away C、the crime of robbing things from shops D、the crime of stealing things from shops (3)Why does the author in Paragraph 2 mention citizen groups forming their own vigilante groups？ A、To show the criminal justice system is not just B、To show citizens are powerful in combating crimes C、To show crime is a serious social problem D、To show citizens have rights in combating crimes (4)According to the passage, which of the following are the factors contributing to United States’criminal behavior？ A、Politics, unemployment, poverty and a large immigrant population. B、Massive urbanization, unemployment and poverty, and a large immigrant population. C、Politics, government corruption, poverty and religion. D、Massive urbanization, unemployment and poverty, and government corruption. (5)Which of the following statements is TRUE according to the passage？ A、Since you have never been robbed, you are not a victim of crime. B、Some people use illegal weapons to defend themselves. C、Only the individual should be responsible for the criminal behavior. D、Family violence and neglect are considered family matters, and therefore private, so they are not crimes.
