第8题：
问答题Advances in technology and science have solved many problems. However，they have also created new problems，among which pollution has attracted much attention of the public. Write a composition of about 400 words on the following topic，discussion the problems caused by pollution.ON POLLUTIONIn the first part of your writing you should present your thesis statement, and in the second part you should support the thesis statement with appropriate details. In the last part you should bring what you have written to a natural conclusion or a summary. Marks will be awarded for content, organization, grammar and appropriateness. Failure to follow the above instructions may result in a loss of marks.正确答案：
ON POLLUTION Nowadays we have many conveniences in our society, which have been brought through technology and science. However, these same advancements in technology and science have caused some very dangerous problems. These problems will not go away easily because people do not want to give up the conveniences of a modem lifestyle. The most critical problems that should be dealt with immediately are those of pollution.
Pollution caused by chemicals is a very serious problem because it causes the loss of the ozone layer. Without our ozone, not only we ourselves but also plant and animal life are exposed to dangerous rays from the sun. Aerosol cans emit chemicals that break down our ozone layer. Refrigeration and air-conditioning systems and ears also have dangerous emissions. A very serious threat to the planet—the warming of the earth's atmosphere—is primarily caused by carbon dioxide emissions. Many scientists think that the warming could be sufficient to melt the polar ice caps, thus raising the sea levels. This would mean that many parts of the world would be submerged below sea level.
There are other problems caused by pollution. Factories that make our modem conveniences emit poisonous gases onto the air we breathe. The chemicals we use for cleaning and wastes from factories go into our water systems and pollute the water we drink and the fish we eat. They also kill much of the wildlife we depend on for food. Some of the pesticides we have sprayed on our crops have been found to be dangerous. This kind of pollution may stay in the ground for a very long period of time.
Last but not the least, nuclear pollution will lead directly to nuclear damage. The explosions at Three Mile Island in the United States in 1979 and at Chernobyl in the Soviet Union in 1986 provided lessons to the global nuclear industry. The exposure to very high radiation levels released by nuclear plants within a short period of time may harm the environment many years, and usually will cause fatal injuries to human health.
In conclusion, the problems created by pollution are growing daily. Because people do not want to change their lifestyles, we must invent a way to neutralize the pollutants we are putting into our environment. People need to be educated so that will stop damaging the planet. Furthermore, government must take action to prevent individuals and companies from harming their environment.解析：

第21题：
问答题The following appeared as part of an article in a daily newspaper: “The computerized on-board warning system that will be installed in commercial airliners will virtually solve the problem of midair plane collisions. One plane’s warning system can receive signals from another’s transponder—a radio set that signals a plane’s course—in order to determine the likelihood of a collision and recommend evasive action.” Discuss how well reasoned you find this argument. In your discussion, be sure to analyze the line of reasoning and the use of evidence in the argument. For example, you may need to consider what questionable assumptions underlie the thinking and what alternative explanations or counterexamples might weaken the conclusion. You can also discuss what sort of evidence would strengthen or refute the argument, what changes in the argument would make it, more logically sound, and what, if anything, would help you better evaluate its conclusion.正确答案：【参考范文】
The argument that this warning system will virtually solve the problem of midair plane collisions omits some important concerns that must be addressed to substantiate the argument. The statement that follows the description of what this warning system will do simply describes the system and how it operates. This alone does not constitute a logical argument in favor of the warning system, and it certainly does not provide support or proof of the main argument.
Most conspicuously, the argument does not address the cause of the problem of midair plane collisions, the use of the system by pilots and flight specialists, or who is involved in the midair plane collisions. First, the argument assumes that the cause of the problem is that the planes’ courses, the likelihood of collisions, and actions to avoid collisions are unknown or inaccurate. In a weak attempt to support its claim, the argument describes a system that makes all of these things accurately known. But if the cause of the problem of midair plane collisions is that pilots are not paying attention to their computer systems or flight operations, the warning system will not solve the collision problem. Second, the argument never addresses the interface between individuals and the system and how this will affect the warning system’s objective of obliterating the problem of collisions. If the pilot or flight specialist does not conform to what the warning system suggests, midair collisions will not be avoided. Finally, if planes other than commercial airliners are involved in the collisions, the problem of these collisions cannot be solved by a warning system that will not be installed on non-commercial airliners. The argument also does not address what would happen in the event that the warning system collapses, fails, or does not work properly.
Because the argument leaves out several key issues, it is not sound or persuasive. If it included the items discussed above instead of solely explaining what the system supposedly does, the argument would have been more thorough and convincing. 解析： 暂无解析 -
