Q: Read the article and select the best answer. Article: Many Chinese kids, known as "left-behind" children, hardly ever see their parents, because their parents are migrant workers. Li Ling, 11, is a left-behind child. Her parents have been working in Zhejiang for 10 years, while she lives with her grandparents in Guangdong. She was reunited with her parents last Spring Festival. As the number of migrant workers in China increases, the number of left-behind children is rising fast. Li is one of the 61. 02 million left-behind children under 17. They account for 37. 7 percent of rural children and 21. 88 percent of all Chinese children The large number of left-behind children has already become a social issue. If left unsolved, it will cause serious problems, Wang Zhenyao, director of the China Philanthropy Research Institute, told China Daily. The education level of adults supervising these children is generally not that high. They can only take care of the children's personal safety and daily living, being unable to care for their educational and spiritual needs. Meanwhile, the absence of parental support will make some left-behind children lack self-confidence. They may be slower in physical and emotional growth than their peers. Others may even become "problem youths". To solve this problem, the government is taking action. For instance, 30 provinces and cities have allowed certain children to attend school and take the college entrance exam in the city where their parents are. However, Wang suggested that the country do more, such as making policies encouraging migrant workers to work in their hometowns. He also said that a well-balanced child welfare system is needed. "These children are the future of the nation, so they deserve our loving care and protection," Wang said. Question: The purpose of the passage is _ . Options: A: to criticize the migrant workers who leave their children at home B: to focus on the present situation of the left-behind children C: to worry about the present situation of left-behind children D: to call on the government to educate the migrant workers
A: B

Q: Read the article and select the best answer. Article: Another common type of reasoning is the search for causes and results.We want to know whether cigarettes really do cause lung cancer, what causes malnutrition, the decay of cities, or the decay of teeth.We are equally interested in effects: what is the effect of sulphur or lead in the atmosphere, of oil spills and raw sewage in rivers and the sea, of staying up late on the night before an examination? Causal reasoning may go from cause to effect or from effect to cause.Either way, we reason from what we know to what we want to find out.Sometimes we reason from an effect to a cause and then on to another effect.Thus, if we reason that because the lights have gone out, the refrigerator won't work, we first relate the effect (lights out) to the cause (power off) and then relate that cause to another effect (refrigerator not working).This kind of reasoning is called, for short, effect to effect.It is quite common to reason through an extensive chain of causal relations.When the lights go out we might reason in the following causal chain: lights out--power off--refrigerator not working--temperature will rise--milk will sour.In other words, we diagnose a succession of effects from the power failure, each becoming the cause of the next. Causes are classified as necessary, sufficient, or contributory.A necessary cause is one which must be present for the effect to occur, as combustion is necessary to drive a gasoline engine.A sufficient cause is one which can produce an effect unaided, though there may be more than one sufficient cause; a dead battery is enough to keep a car from starting, but faulty spark plugs or an empty gas tank will have the same effect.A contributory cause is one which helps to produce an effect but cannot do so by itself, as running through a red light may help cause an accident, though other factors -- pedestrians or other cars at the crossroads -- must also be present. In establishing or refuting a causal relation it is usually necessary to show the process by which the alleged cause... Question: According to the passage, to do the "effect to effect" reasoning is to reason _ . Options: A: from cause to effect B: from effect to cause C: from effect to effect and on to cause D: from effect to cause and on to another effect
A: D

Q: Read the article and select the best answer. Article: Imagine, one day,getting out of bed in Beijing and being at your office in Shanghai in only a couple of hours,and then,after a full day of work,going back home to Beijing and having dinner there. Sounds unusual,doesn't it? But it's not that unrealistic,with the development of China's high-speed railway system.And that's not all.China has an even greater high-speed railway plan -- to connect the country with Southeast Asia,and eventually Eastern Europe. China is negotiating to extend its own high-speed railway network to up to 17 countries in 10 to 15 years,eventually reaching London and Singapore. China has proposed three such projects.The first would possibly connect Kunming with Singapore via Vietnam and Malaysia.Another could start in Urumqi and go through Kazakhstan and Uzbekistan,and possibly to Germany.The third would start in the northeast and go north through Russia and then into Western Europe. If China's plan for the high-speed railway goes forward,people could zip over from London to Beijing in under two days. The new system would still follow China's high-speed railway standard.And the trains would be able to go 346 kilometers an hour. China's bullet train ,the one connecting Wuhan to Guangzhou,already has the World's fastest average speed.It covers 1,069 kilometers in about three hours. Of course,there are some technical challenges to overcome.There are so many issues that need to be settled,such as safety,rail gauge ,maintenance of railway tracks.So,it's important to pay attention to every detail. But the key issue is really money.China is already spending hundreds of billions of yuan on domestic railway expansion. China prefers that the other countries pay in natural resources rather than with capital investment.Resources from those countries could stream into China to sustain development. It'll be a win-win project. For other countries,the railway network will definitely create more opportunities for business,tourism and so on,not to mention the better communication among those countries. For... Question: China's new high-speed railway plan will be a win-win project because _ . Options: A: China will get much-needed resources and develop its western regions B: China and the countries involved will benefit from the project in various ways C: China will develop its railway system and communication with other countries D: The foreign countries involved will develop their business and tourism
