单选题 More than a century ago, the relationship between glacial ice and the amount of water in the ocean basins was first seen. When the great ice sheet covered vast land areas, the sea level was lowered because the normal return of water from land to the ocean was reduced. As a result, the sea level rose as Ice Age glaciers melted allowing the melted waters to flow into the ocean. If all the glacial ice on the surface of the earth today should melt, the sea level might rise by more than 150 feet. Shoreline variations are also produced through elevation or depression of the land. During times of glacier formations the great weight of the ice slowly depressed the earth's crust. Removal of the weight through glacier melting allowed the slow return of the crust to its former position. Changes in the Great Ice climates from cool and wet to warm and dry produced climate changes far from the glaciated are A. For example, at times of cool-wet glacial climates, levels of inland lakes rose, in contrast to the depression of sea level. During the warm-dry interglacial climates, lake levels were lowered. The ancient lake Bonneville, largest of the glacial lakes in Western United States, once covered more than 20,000 square miles. It had a maximum depth of more than 1,000 feet. Great Salt Lake in Utah is the shrunken remnant of this once large lake. Although the first time that early man walked on the earth is uncertain, he is largely a product of the Great Ice Age. Present information shows that during this time he evolved rapidly both physically and culturally. His most primitive tools and skeletal remains have been found in some of the oldest deposits contemporary with the Great Ice Age in Africa, Asia and Europe. These are often associated with remains of extinct animals. With the disappearance of the great ice sheets, the Bronze and Iron Age cultures evolved. About this time many animals suited to cooler climates died. Although much remains to be learned, the story of the Great Ice Age is being unfolded through the efforts of specialists in many fields. Recording field observation, new theories and methods, and worldwide studies of existing glaciers are bringing a clearer understanding of the Great Ice Age.

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.
