China's Ministry of Culture has recommended 10 cyber games that are suitable for minors to play as part of its drive to purify the on-line environment for the young. The 10 cyber games were selected by the ministry's on-line games censorship committee from scores of games recommended by the Chinese public.l The games are all domestic products. They include five role playing games (RPG), four recreation and chess games, and one educational game, such as "Warring States II Online," "Rainbow Island Online," and "Wonderlands of learning and games." These games have made their way into the final recommendation list because they are considered "healthy" and can "enhance intelligence," according to the ministry. The ministry hoped the list could serve a a guidance for parents to better direct their children in the winter vacation, which usually lasts nearly two months from January to February each year. This was the third time for the ministry to publish recommended cyber games list. The previous two were made public respectively in January 2006 and August 2005 with a total of 25 games inlisted. In the past few years, on- line games have become the favorite pastime of young people. However, it is argued that such social problems as game addiction, juvenile delinquency and perversion among minors by on-line violence and pornography have come from an inadequately regulated Internet. About 9.72 percent of Chinese netizens between the ages of 13 and 30 suffer Internet addiction, said a report issued last month by the China Youth Association for Network Development (CYAND). According to the China Internet Network Information Center (CINIC), the main Internet watchdog, China had 210million Internet users at the end of 2007 and its online population is on course to become the world's largest at the beginning of this year. Net users between 18 and 30 accounted for 49.9percent of the total users. Although the CINIC did not give the figure of those below 18, teenagers and youths have obviously taken up more than half of... What can be inferred from the passage? A) A lot of Chinese netizens suffer Internet addition. B) On-line games can cause a lot of social problems such as game addition, juvenile delinquency. C) Parents sometimes have trouble in directing their children about on-line games. D) The ministry has recommended 25 games till now.

Climate change could affect food supplies, water resources, human health and homes. If greenhouse gas emissions keep increasing at the current rate, global temperature is expected to rise between 2degC and 6degC by 2100. This doesn't sound much, but a 5degC change is the difference between the current warm period and an ice age. Global warming leads to other changes in the climate: melting ice, more evaporation , changes in geographical patterns of rainfall, heavier downpours separated by longer dry spells, more frequent heat waves, more intense hurricanes, and sea level rise. These changes could affect crop growth as drought, increased evaporation and shrinking glaciers disrupt water supply. Some crops could suffer heat stress. While there may be benefits in some regions, overall climate change is likely to have a negative impact on global food supplies. The impacts of climate change on agriculture will vary widely around the world. A global temperature rise of 1-2 degC is expected to increase food production in some regions, particularly mid-latitude areas. But in tropical regions even a small amount of warming could reduce crop yields. A temperature rise of 3 degC or more could threaten global food resources, as all regions are likely to experience negative impacts overall. Freshwater resources could also diminish, especially in tropical regions, as rain patterns change and evaporation speeds up. Some communities could lose essential melt water as glaciers disappear, while more intense rainfall and hurricanes could cause more flooding, leading to water pollution and bacterial diseases such as cholera becoming more widespread. Climate change could lead to a variety of health impacts - both positive and negative. On the negative side, scientists anticipate more cases of malnutrition, heatstroke and waterborne diseases such as cholera. Although some populations will benefit from a reduced risk of cold-related illnesses such as _ , overall a warming world is likely to have negative effects on human... The passage is mainly meant to tell us _ . A) how global warming leads to changes in the climate B) how climate change affects people worldwide C) why climate change affects our crop growth D) why climate change contributes to all bad results

Ques: A tropical rain forest is an amazing place. Thousands of different kinds of plants and animals make their homes there. Some are not found anywhere else in the world. If the rain forests are not protected, some species of plants and animals could disappear forever, taking their resources with them. Scientists have known for a long time that medical cures can come from plants. The rain forest is the perfect habitat for various types of plants. They compete for space, sunlight, water, and nutrients. The plants that survive are strong. They also contain many types of chemicals. These chemicals are part of the plants' defence system. They can help protect the plants from bacteria, insects, diseases, and other threats. Experts believe that some of these chemicals might be useful to human beings, too. The native people of the rain forests have healers who help those who are sick. For hundreds of years, they have known which leaves, roots, and berries can be used to treat different illnesses. Western scientists have begun working with these native healers. They learn about different plants, cures, and treatments. Then, they can perform tests on the plants to see what chemicals they contain and how they might be used. When they do find something important, it goes through more and more tests. Lots of experiments must be done over a long period of time before something can be safely sold as a drug. Scientists want to be sure that it works and that the risk of using it isn't too high. American scientists have set up labs in the countries where the rain forests are. They do studies and research there. They also employ scientists and workers who live in these countries to help them. This allows the local people to benefit from research on the rain forests. They can make money from the rain forest without destroying it, which is very important. If the rain forest is valuable to them, they will help protect it. The more people who are trying to protect the rain forests, the better. Just imagine the cures that might be... The text is mainly about_. A) the native healers of the rain forests B) the plants and animals living in the rain forests C) the medicinal value of plants in the rain forests D) the diseases which attack plants in the rain forests
Ans: C
Your body, which has close relations with the food you eat, is the most important thing you own, so it needs proper treatment and proper nourishment . The old saying "an apple a day keeps the doctor away." is not as silly as some people think. The body needs fruit and vegetables because they contain vitamins. Many people take extra vitamins in pill form , believing that these will make them healthy. But a good diet is made up of nutritive food and this gives all the vitamins you need. The body doesn't need or use extra vitamins, so why they waste money on them? In the modern Western world, many people are too busy to bother about eating properly. They throw anything into their stomachs, eating hurriedly and carelessly. The list of illnesses caused or made worse by bad eating habits is frightening. In the modern western countries _ . A) people won't want to pay more attention to their eating B) people throw everything into their stomachs without chewing. C) list of people's illness are caused or made worse by bad eating habits D) people are only too busy to cook meals for themselves
