A. follow the fashion B. show themselves off C. keep pace with the times D. improve their quality of life D The United States estimates that about one out of every 10 people on the pla today is at least 60 years old. By 2050, it’s projected to be one out of 5. This means that not only will there be more old people, but there will be relatively fewer young people to support them. Professor Richard Lee of the University of California at Berkeley says this aging of the world has a great effect on economics. “Population aging increases the concentration of population in the older ages and therefore it is costly,” he said. Aging populations consume (消耗 ) more and produce less. With more people living longer, it could get expensive. But Mr. Lee says with continuing increases in worker productivity and smart planning, it can be manageable. Societies have different methods for caring for the elderly, but each carries a cost. Generally, there are three types of support. Seniors can live off the wealth they gained when they were younger. They can rely on their family to take care of them, or they can rely on the government. In industrialized nations, governments created publiclyfunded (公共資助的 ) support systems. These worked relatively well until recent years, when aging population growth in places like the United States and Western Europe began to gradually weaken the systems finances. These nations now face some tough choices. Mr. Lee says the elderly in some of these countries must either receive less money, retire later or increase taxes to make the system continuable. Most developing nations haven’t built this type of government funded support, but have instead relied on families to care for their elderly. These nations also generally have a much younger population, which means their situation is not as urgent as more developed nations. But Mr. Lee says that doesn’t mean they can ignore the issue. “Third World countries should give very careful thought to this process, to population aging and how it may affect their economies — now, before population aging even bees an issue,” he explained. 32. “Aging” in this text means . A. there are more young people than old people B. an increasing number of old people are dying C. more and more young people are growing old D. the percentage of old people in the world is increasing 33. What is Professor Richard Lee’s attitude towards population aging? A. Indifferent. B. Optimistic. C. Negative. D. Worried. 34. The publiclyfunded support systems in industrialized nations .

A. should prepare for population aging B. don’t see population aging as an issue C. are facing urgent situations of population aging D. have better ways to deal with population aging 第二節(jié) (共 5 小題；每小題 2 分，滿分 10 分 ) 根據(jù)短文內(nèi)容，從短文后的選項中選出能填入空白處的最佳選項，并在答題卡上將 該項涂黑。選項中有兩項為多余選項。 注意：涂卡時， E 涂 AB， F 涂 AC， G 涂 AD。 Caner Cancer is a disease that causes certain cells in the body to grow out of control. The human body contains billions of cells. Most of these cells reproduce themselves over and over. The body normally controls this process. In some people, however, certain cells start to multiply (繁殖 ) too much. These cells are not normal and can produce tumors (腫瘤 ). Some tumors are harmless, but others are very serious. 36 These destructive tumors are called cancer. Cells from these tumors sometimes spread to other parts of the body and form more tumors. There are many different kinds of cancer. The kind of cancer a person has depends on where it starts to grow. 37 There are some general symptoms(癥狀 ) that may mean a person has cancer. These symptoms include pain, weight loss that cannot be explained, fever, tiredness, and changes in the skin. 38 For example, a cough that will not go away could be a sign of lung cancer. Scientists don’t know why some cells multiply too quickly. However, they have discovered many things that can lead to cancer. Most cancers are caused by conditions outside the body. 39 People have a higher chance of getting some kinds of cancer if members of their families had them. A few viruses (病毒 ) also cause cancer. The easiest way to prevent cancer is to stay away from the things that might cause it. 40 Seeing a doctor once a year helps, too. Doctors can find early warning signs of cancer. A. They can destroy nearby healthy cells. B. Getting too much sunlight can cause skin cancer. C. Each kind of cancer also produces specific symptoms. D. It also depends on what causes it and how fast it grows. E. Doctors suggest that people wear sunglasses when outdoors. F. Eating unhealthy foods and not exercising enough can also lead to cancer. G. Exercise and eating a lot of fruits and vegetables can also help to prevent cancer. 第三部分 英語
