单选题Trees should only be pruned (修剪) when there is a good and clear reason for doing so and, fortunately, the number of such reasons is small. Pruning involves cutting away of overgrown and unwanted branches, and the inexperienced gardener can be encouraged by the thought that more damage results from doing it unnecessarily than from leaving the trees to grow in their own ways. First, pruning may be done to make sure that trees have a desired shape or size. The object may be to get a tree of the right height, and at the same time to help the growth of small side branches which will thicken its appearance or give it a special shape. Secondly, pruning may be done to make the tree healthier. You may cut out diseased or dead wood, or branches that are rubbing against each other and thus causing wounds. The health of a tree may be encouraged by removing the branches that are locking up the centre and so preventing the free movement of air. One result of pruning is that an open wound is left on the tree and this provides an easy entry for diseases, but it is a wound that will heal (愈合). Often there is a race between the healing and the disease as to whether the tree will live or die, or that there is a period when the tree is at risk. It should be the aim of every gardener to reduce the risk as far as possible. It is essential to make the area which has been pruned smooth and clean, for healing will be slowed down by roughness. You should allow the cut surface to dry for a few hours and then paint it with one of the substances available from garden shops produced especially for this purpose. Pruning is usually done in winter, for then you can see the shape of the tree clearly without the interference (妨碍) from the leaves and it is, too, very unlikely that the cuts you make will bleed. If this does happen, it is, of course, impossible to paint them properly.

单选题Prolonging human life has increased the size of the human population. Many people alive today would have died of childhood diseases if they had been born a hundred years ago. Because more people live longer, there are more people around at any given time. In fact, it is a decrease in death rates, not an increase in birth rates, that has led to the population explosion.Prolonging human life has also increased the dependency load. In all societies, people who are disabled or too young or too old to work are dependent on the rest of society to provide for them. In hunting and gathering cultures, old people who could not keep up might be left behind to die. In times of famine, infants might be allowed to die because they could not survive if their parents starved, whereas if the parents survived they could have another child. In most contemporary (当代的) societies, people feel a moral obligation to keep people alive whether they can work or not. We have a great many people today who live past the age at which they want to work or are able to work; we also have rules which require people to retire at a certain age. Unless these people were able to save money for their retirement, somebody else must support them. In the United States many retired people live on social security checks which are so little that they must live in near poverty. Older people have more illness than young or middle-aged people; unless they have wealth or private or government insurance, they must often go on welfare if they have a serious illness.When older people become senile or too weak to care for themselves, they create grave problems for their families. In the past and in some traditional cultures, they would be cared for at home until they died. Today, with most members of a household working or in school, there is often no one at home who can care for a sick or weak person. To meet this need, a great many nursing homes and convalescent (康复的) hospitals have been built. These are often profit-making organizations, although some are sponsored (赞助) by religious and other nonprofit groups. While a few of these institutions are good, most of them are simply dumping grounds for the dying in which care is given by poorly paid, overworked, and under-skilled personnel.

单选题Hitchhiking When I was in my teens (十几岁) and 20s, hitchhiking was a main form of long-distance transport. The kindness or curiosity of strangers 1 me all over Europe, North America, Asia and southern Africa. Some of the lift-givers became friends, many provided hospitality 2 the road. Not only did you find out much more about a country than 3 traveling by train or plane, but also there was that element of excitement about where you would finish up that night. Hitchhiking featured importantly in Western culture. It has books and songs about it. So what has happened to 4 ? A few years ago, I asked the same question about hitchhiking in a column on a newspaper. 5 of people from all over the world responded with their views on the state of hitchhiking. "If there is a hitchhiker"s 6 it must be Iran," came one reply. Rural Ireland was recommended as a friendly place for hitchhiking, 7 was Quebec, Canada. "If you don"t mind being berated (严厉指责) for not speaking French." But while hitchhiking was clearly still alive and well in many parts of the world, the 8 feeling was that throughout much of the west it was doomed (消亡). With so much news about crime in the media, people assumed that anyone on the open road without the money for even a bus ticket must present a danger. But do we 9 to be so wary both to hitchhike and to give a lift? In Poland in the 1960s, 10 a Polish woman who e-mailed me, "the authorities introduced the Hitchhiker"s Booklet. The booklet contained coupons for drivers, so each time a driver 11 somebody, he or she received a coupon. At the end of the season, 12 who had picked up the most hikers were rewarded with various prizes. Everybody was hitchhiking then." Surely this is a good idea for society. Hitchhiking would increase respect by breaking down 13 between strangers. It would help fight 14 warming by cutting down on fuel consumption as hitchhikers would he using existing fuels. It would also improve educational standards by delivering instant 15 in geography, history, politics and sociology.

单选题Disagreements among economists are legendary, but not on the issue of free trade. A recent survey of prominent economists both conservative and liberal concluded that an economist who argues for restricting international trade is almost as common today as a physician who favors leeching. Why the consensus? International free trade, economists agree, makes possible higher standards of living all over the globe. The case for free trade rests largely on this principle: as long as trade is voluntary, both partners benefit, otherwise they wouldn't trade. The buyer of a shirt, for example, values the shirt more than the money spent, while the seller values the money more. Both are better off because of the sale. Moreover, it doesn't matter whether the shirt salesman is from the United States or Hong Kong (or anywhere else). The vast majority of American manufactures face international competition. This competition forces companies to improve quality and cut costs. By contrast, protectionism encourages monopoly, lower quality and higher prices. Americans pay an enormous price for protectionism over $60 billion a year, or $1000 for a family of four. Thanks to protectionism, for example, American consumers pay twice the world price for sugar. Free trade also makes the world economy more efficient, by allowing nations to capitalize on their strengths. The United States has an advantage in food production, for instance, while Saudi Arabia has an advantage in oil. The Saudis could undertake massive irrigation to become self-sufficient in food, but it is more economical for them to sell oil and purchase food from us. Similarly, we could become self-sufficient in petroleum by squeezing more out of oil shale. But it is much less costly to buy some of our oil from Saudi Arabia. Trade between our two countries improves the standard of living in both. Protectionism is both wasteful and unjust. It taxes most heavily the people who can least afford it. Thus, tariffs that raise the price of shoes burden the poor more than the rich. Despite the powerful case for free trade, the United States and the rest of the world have always been protectionist to some degree. This is because free trade benefits the general public, while protectionism benefits special interest groups, which are better organized, better financed and more informed. To make matters worse, much of what we hear on this issue is misinformation spread by the special interests themselves.
