There are three separate sources of danger in supplying energy by nuclear power. First, the radioactive material must travel from its place of production to the power station. Although the power stations themselves are strongly built, the containers used for the transport of the materials are not. Normally, only two methods of transport are in use, namely road or rail. Unfortunately, both of these may have an effect on the general public, since they are sure to pass near, or even through, heavily populated areas. Second, there is the problem of waste. All nuclear power stations produce wastes that in most cases will remain radioactive for thousands of years. It is impossible to make these wastes non-radioactive, and so they must be stored in one of the inconvenient ways that scientists have invented. For example, they may be buried under the ground, or dropped into deserted mines, or sunk in the sea. However, these methods do not solve the problem, since an earthquake could easily break the containers. Third, there may occur the danger of a leak or an explosion at the power station. As with the other two dangers, this is not very likely, so it does not provide a serious objection (,) to the nuclear program. However, it can happen. Separately, these three types of dangers are not a great cause for worry. Taken together, though, the probability of disaster is extremely high. What is this passage about? A) Uses of nuclear power. B) Dangers from nuclear power. C) Public anger at nuclear power. D) Accidents caused by nuclear power.

Experts say that agriculture provides fourteen percent of the world's greenhouse gas emissions each year. The gases released include carbon dioxide, a major cause of global warming. Twenty-one nations around the world recently joined forces to better understand and prevent greenhouse gas emissions from farms. The Global Research Alliance on Agricultural Greenhouse Gases was launched at the United Nations conference on climate change. The meeting took place in Copenhagen,Denmark last month. Agricultural experts blame a number of farm activities for producing greenhouse gases. For example, animal waste and cattle digestive systems release methane(,) gas. Fertilized soil and the burning of crop waste also release harmful gases into the air. Experts say some methods of farming---turning the soil to prepare for planting---also release harmful carbon dioxide. An official of the European Commission's Directorate Genera1 for Research says agricultural greenhouse gas emissions can be cut. Maive Rute suggests feeding animals a diet designed to reduce emissions. The new agricultural research group says protecting against global warming is only part of its purpose. It says the world also needs to develop better farming methods to feed growing populations in poor countries. United States Agriculture Secretary Tom Vilsack said no one single nation can fight agricultural greenhouse gas emissions and increase food production at the same time. This is why the _ e is important for combining resources and finding new ones. The United States Department of Agriculture (USDA) will increases spending on farm emissions research by ninety million dollars over the next four years. The total will reach one hundred thirty million dollars. The USDA will share the research with other countries in the Global Research Alliance on Agricultural Greenhouse Gases and support researchers from developing countries that belong to the alliance. Money from the Borlaug Fellowship program will let the researchers study agricultural climate... How much has the USDA spent on farm emissions research so far? A) 130 million dollars. B) 220 million dollars C) 40 million dollars. D) 90 million dollars.

Q: Many of us mistakenly believe that it's wrong to think we have any good qualities. We may spend a lot of time blaming ourselves for our negative qualities, thinking that self criticism is the key to improving our performance. However, a constant focus on our supposed shortcomings can stop our efforts to make friends with other people. How can we believe that others could like us if we believe our inner being is flawed? If someone seems to dislike you, the reason for that dislike might have little or nothing to do with you. The person who doesn't like you might be fearful, or shallow or busy or shy. Perhaps you and that person are simply a mismatch for each other at this particular time. Don't take yourself out of the game by deciding that your flaws are bigger than your good qualities. In fact, some of the very qualities you consider to be flaws may be irresistible to someone else. Although some factors that might cause one person to reject you, there are at least many factors that will work in your favor. You might be thirty pounds over your ideal weight, but you may have a wonderful laugh and a real enthusiasm for life. There are many people who don't mind your extra pounds. You may drive a shabby car, but you might be a great dancer and a loyal friend. There are people out there looking for loyalty, or fun, or sweetness, or wisdom, and the package it comes in is not important. If you are worried that you are not beautiful enough to attract friends, keep in mind that not everyone is looking for physical beauty in their friends. You can decide to feel inferior because you don't have much money and you don't drive a nice car. You can believe that this is the reason that you don't have many friends in your life. On the other hand, if you are very wealthy you may be suspicious that everyone is after your money and that nobody really likes you as a person. The point is that you can focus on just about anything and believe it's the reason you do not have friends and cannot make any. Which of the following is TRUE according to the author? A) It is important to lose weight. B) It is easier for a wealthy person to make friends. C) Inner qualities are more important than physical appearance. D) If you are not beautiful enough, try to improve your physical beauty.

Recent weeks have seen a wave of new books, stamps, movies, television programmes, newspaper articles, songs and performances, all celebrating the 100thanniversary of the birth of Deng Xiaoping, on August 22. To Chinese people, he was no doubt one ofprefix = st1 /China's greatest leaders. Many Westerners remember Deng as "a little man with great ideas". He was famous for his practical and direct manner, shown in famous slogans such as "No matter if it is a white cat or a black cat; a cat that can catch rats is a good cat" and "Poverty is not socialism". In 1979, as the first top Chinese communist leader to set foot in theUnited States, he was regarded as a symbol of friendship when he wore a cowboy hat inHouston,Texas, and rode around in a stage coach. "His straightforward manner earned the trust of the American people. He changed the American people's traditional view of Chinese leaders andChina," said David Lampton, a well-known American expert onChina. "He succeeded in strengthening Chinese diplomatic relations." Lampton said that Deng openedChinaup to the rest of the world and helped develop more friendly relations with the West. "Deng's reform increased the world's understanding of Chinaand today Americans are no longer afraid ofChina," said Mike Wallace, an American journalist who interviewed Deng in 1986. At that time, he said,Chinawas still mysterious in the eyes of Westerners. Talking of his impression of Deng, Wallace said he was very honest and clever. He recalled a conversation at the beginning of the interview. "I started the interview by saying 'reporters don't normally get to meet you'. Deng answered, 'Because I am an ordinary person'. Then I asked, 'Why did you decide to have the interview with us at this time?' He replied, 'Because I want to know American people and that they can know Chinabetter; by American people I also mean American leaders'." Though he interviewed many international leaders, Wallace thought Deng was very different form them all. Maybe the fact that Deng... Which of the following isn't the result of Deng's visiting Americain 1979? A) It made Americans no longer afraid of China B) It opened Chinaup to the world C) It developed the relations between Chinaand theUS D) It changed Westerners' view of China
