Read the article and select the best answer. Article: As far back as 700 B. C, man has talked about children being cared for by wolves. Romulus and Remus, the legendary twin founders of Rome, were said to have been cared for by wolves. It is believed that when a she-wolf loses her litter, she tries to get human child to take its place. This seemingly foolish and unreasonable idea did not become believable until the late nineteenth century when a French doctor actually found a ten-year-old boy having nothing on wandering in the woods. He didn't walk upright, could not speak understandably, nor could he relate to people. He only growled and stared at them. Finally the doctor won the boy's confidence and began to work with him. After many long years of devoted and patient teaching, the doctor was able to get the boy to clothe and feed himself, recognize and say a number of words, as well as write letters and form words. Question: In this passage, the word "litter" in line 3 most nearly means _ . Options: A: garbage B: master C: hair D: baby animals
(Answer)
D

Read the article and select the best answer. Article: The State Council declared Wednesday it would restart China's nuclear power program, ending the hiatus in nuclear construction since Japan's Fukushima nuclear disaster last year. China has been the most courageous country in building nuclear power, with the largest number of plants currently under construction. Nuclear power is facing a tough time in developed countries. The Japanese public is demanding the closure of all the country's nuclear power plants. China is at the forefront of nuclear power development. But it has been forced into this position. Rapid economic development coupled with improvements in people's life both demand more electricity. It is impossible to exploit fossil resources forever as the supply of coal, oil and natural gas is limited. China has no choice but to develop nuclear power. China must be the safest user of nuclear power. It should become a leading country in developing nuclear power technologies and increasing the world's knowledge of nuclear power. It needs to do at least two things. First, it needs to promote safety in nuclear power plants, based on the technologies of the West. The former Soviet Union, the US and Japan all had severe nuclear accidents, proving there are risks. China should try to remove these risks. Second, China should establish effective communication mechanisms between the government, power plants and the public. It's wrong to think the government can control every aspect of nuclear power plant construction. The opposition to nuclear power program in developed countries has prevented them from building new plants, but they already have many. These governments are reluctant to close these plants despite strong opposition, because they cannot find better substitutes. Nuclear power only occupies 1.8 percent of China's current electricity grid , much lower than the proportion in many developed countries. China's nuclear power plan should introduce the advantages of the technologies of other countries and also be creative in providing security. Its space... Question: What attitude do people in developed countries have towards nuclear power program? Options: A: Supportive. B: Opposed. C: Indifferent. D: Objective.

Read the article and select the best answer. Article: Until recently, the "science of the future" was supposed to be electronics and artificial intelligence. Today it seems more and more likely that the next great breakthroughs in technology will be brought through a combination of those two sciences with organic chemistry and genetic engineering. This combination is the science of biotechnology. Organic chemistry enables us to produce marvelous synthetic materials. However, it is still difficult to manufacture anything that has the capacity of wool to conserve heat and also to absorb moisture. Nothing that we have been able to produce so far comes anywhere near the combination of strength, lightness and flexibility that we find in the bodies of ordinary insects. Nevertheless, scientists in the laboratory have already succeeded in "growing" a material that has many of the characteristics of human skin. The next step may well be "biotech hearts and eyes" which can replace diseased organs in human beings. These will not be rejected by the body, as is the case with organs from humans. The application of biotechnology to energy production seems even more promising. In 1996 the famous science fiction writer, Arthur C. Clarke, many of whose previous predictions have come true, said that we may soon be able to develop remarkably cheap and renewable sources of energy. Some of these power sources will be biological. Clarke and others have warned us repeatedly that sooner or later we will have to give up our dependence on non-renewable power sources. Coal, oil and gas are indeed convenient. However, using them also means creating dangerously high levels of pollution. It will be impossible to meet the growing demand for energy without increasing that pollution to catastrophic levels unless we develop power sources that are both cheaper and cleaner. It is attempting to think that biotechnology or some other "science of the future" can solve our problems. Before we surrender to that temptation we should remember nuclear power. Only a few generations ago it seemed to... Question: The materials produced with organic chemistry are _ .at present. Options: A: as good as wool B: as good as an insect's body C: better than natural materials D: not as good as natural materials
