Read the following article and select the best answer. Article: Ever since Canadian psychiatrist Michael R. Phillips, who works in China, released his report saying China's suicide rate from 1995 to 1999 reached 0.023 percent, the country has been ranked among those with the highest suicide rates in the world. But Jing Jun, a professor of sociology in Tsinghua University, challenges that view and presents the true picture through his nationwide research. Jing and his students took one year to set up the first national database on suicide rate to grasp the overall trend of suicides in China. They collected data from the Health Statistics Annuals of the World Health Organization (sample size 10 million), and the country's Health Statistics Annuals (which cover 100 million people). The database covers 23 years, from 1987 to 2009. Jing calculates the suicide rate in China based on these data. Though the suicide rate was comparatively high in the early years, his study shows it has dropped in recent years, as opposed to the ascending trend in the rest of the world. According to Jing's calculation, China's suicide rate had dropped to about 0.01 percent in 2004. In 2009, the figure dropped further to 0.007 percent, which is rather low compared with the global rate of 0.016 percent. Even if the "missing" suicides were added, China's suicide rate in 2009 would still be below 0.008 percent.[:Zxxk.Com] Jing has found that one of the main reasons why the suicide rate has dropped was the steady and big decline in the number of suicides committed by rural women. In the early years, researchers generally agreed that the suicide rate among Chinese women was higher than among men, which is pretty rare in the rest the world. But the suicide rate among Chinese women, especially in rural areas, has declined remarkably in recent years. In fact, it is almost equal to that of Chinese men. As a sociologist, Jing regards suicide as a social issue, and believes improvement of social policies will reduce the suicide rate even further. More people's lives can be saved if the authorities adjust to... Question: Why has the suicide rate in China dropped steadily according to Jing Jun? - Because the life level of Chinese people has improved a lot. - Because China's government has adopted measures to reduce the suicide rate. - Because the number of Chinese women who commit suicide has declined. - Because the world environment affects the suicide rate in China.
**Answer**
Because the number of Chinese women who commit suicide has declined.

Read the following article and select the best answer. Article: It's 10 pm. You may not know where your child is, but the chip does. The chip will also know if your child has fallen and needs immediate help. Once doctors arrive, the chip will also be able to tell them which drugs are not suitable for little Johnny or Janie. At the hospital, the chip will tell doctors his or her complete medical history. And of course, when you arrive to pick up your child, settling the hospital bill with your health insurance policy will be a simple matter of waving your own chip-the one embedded in your hand. To some, this may sound unbelievable. But the technology for such chips is no longer the stuff of science fiction. And it may soon offer many other benefits besides locating lost children or elderly patients. It could be used as credit cards and people won't have to carry wallets anymore. On the other hand, some are already wondering what this sort of technology may do to the sense of personal privacy and liberty. "Any technology of this kind could result in abuse of personal privacy," says Lee Tien, senior staff attorney for the Electronic Frontier Foundation. "If a kid can be tracked, do you want other people to be able to track your kid? It's a double-edged sword." Applied Digital Solutions, Inc. in Palm Beach, Florida, says it has recently applied to the Food and Drug Administration for permission to begin testing its device in humans. About the size of a grain of rice, the microchip can be encoded with bits of information and embedded in humans under a layer of skin. When scanned by a nearby reader, the embedded chip gives the data. Most embedded chip designs are so-called passive chips, which give information only when scanned by a nearby reader. But active chips-such as the proposed Digital Angel of the future-will give out information all the time. And that means designers will have to develop some sort of power source that can provide a continuous source of energy, yet be small enough to be embedded with the chips. In addition to technical problems, many suspect... Question: It is indicated in the passage that chip producers have to consider the following issues EXCEPT _ . - financial problems - technical problems - legal problems - privacy problems
**Answer**
financial problems

Read the following article and select the best answer. Article: From hitting the mall with your girl friends on a Saturday afternoon, to holiday spending on gifts that go under the tree, shopping could be called one of America's favorite pastimes. For most people, it means some new clothes for work or a small trinket for a friend. For others, however, shopping is much more than an enjoyable pastime, and in some cases, it is a real and destructive addiction that can turn into a financial disaster. Compulsive shopping and spending are defined as inappropriate, excessive, and out of control. Like other addictions, it basically has something to do with impulsiveness and lack of control over one's impulses. In America, shopping is embedded in our culture; so often, the impulsiveness comes out as excessive shopping. Sometimes this is referred to as "shopholism". Shopping addiction can damage a person's life, family, and finances. "No one knows what causes addictive behaviors, like shopping, alcoholism, drug abuse, and gambling", says a professor of applied health science. Some of the new evidence suggests that some people, maybe 10%-15%, may have a genetic predisposition to an addictive behavior, coupled with an environment in which the particular behavior is triggered, but no one really knows why." Individuals will get some kind of high from an addictive behavior like shopping. What are the telltale signs that shopping has crossed the line and become and addiction? What should a concerned family member or friend look out for when they think shopping has become a problem? The behaviors can signal a serious problem: *Shopping or spending money as a result of feeling angry, depressed, anxious, or lonely *Having arguments with others about one's shopping habits *Feeling lost without credit cards -- actually going into withdrawal without them *Buying items on credit, rather than with cash *Describing a rush or a feeling of euphoria with spending *Feeling guilty, ashamed, or embarrassed after a spending spree *Thinking obsessively about money *Spending a lot time juggling accounts... Question: The best title of this article is _ - Should We Shop or Not? - Shopping Behaviors, Good or Bad? - Shopping Spree, or an Addiction? - The Dangers of Shopholism.
**Answer**
Shopping Spree, or an Addiction?
