单选题 Directions: There are 20 blanks in the following passage. For each blank there are four choices marked A), B), C) and D) on the right side of the paper. You should choose the ONE that best fits into the passage. Then mark the corresponding letter on Answer Sheet 2 with a single line through the centre. Today, most countries in the world have canals. Many countries have built canals near the coast, and parallel {{U}}(67) {{/U}} the coast. Even in the twentieth century, goods can be moved more cheaply by boat than by any other {{U}}(68) {{/U}} of transport. These waterways make it {{U}}(69) {{/U}} for boats to travel {{U}}(70) {{/U}} ports along the coast without being {{U}}(71) {{/U}} to the dangers of the open. Some canals, such as the Suez and the Panama, save ships weeks of time by making their {{U}}(72) {{/U}} a thousand miles shorter. Other canals permit boats to reach cities that are not {{U}}(73) {{/U}} on the coast, still other canals {{U}}(74) {{/U}} lands where there is too much water, help to {{U}}(75) {{/U}} fields where there is not enough water, and {{U}}(76) {{/U}} water power for factories and mills. The size of a canal {{U}}(77) {{/U}} on the kind of boats going through it. The canal must be wide enough to permit two of the largest boats using it to {{U}}(78) {{/U}} each other easily. It must be deep enough to leave about two feet of water {{U}}(79) {{/U}} the keel (船的龙骨) of the largest boat using the canal. When the planet Mars was first {{U}}(80) {{/U}} through a telescope, people saw that the round disk of the planet was crisscrossed by a {{U}}(81) {{/U}} of strange blue-green lines. These were called "canals" {{U}}(82) {{/U}} they looked the same as canals on earth {{U}}(83) {{/U}} are viewed from an airplane. However, scientists are now {{U}}(84) {{/U}} that the Martian phenomena are really not canals. The photographs {{U}}(85) {{/U}} from space-ships have helped us to {{U}}(86) {{/U}} the truth about the Martian "canals".

单选题Trees should only be pruned when there is a good and clear reason for doing so and, fortunately, the number of such reasons is small. Pruning involves the 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 tree to grow in its own way. 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 diseased or dead wood, or branches that are rubbing against each other and thus cause wounds. The health of a tree may be encouraged by removing branches that are blocking 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 disease, but it is a wound that will heal. Often there is a race between the healing and the disease as to whether the tree will live or die, so that there is a period when the tree is at risk. It should be the aim of every gardener to reduce 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 without interference from the leaves and also it is 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Over the past 600 years, English has grown from a language of few speakers to become the dominant language of international communication. English as we know it today emerged around 1350, after having incorporated many elements of French that were introduced following the Norman invasion of 1066. Until the 1600s, English was, for the most part, spoken only in England and had not extended even as far as Wales, Scotland, or Ireland. However, during the course of the next two centuries, English began to spread around the globe as a result of exploration, trade (including slave trade), colonization and missionary work. Thus, small enclaves (聚居地) of English speakers became established and grew in various parts of the world. As these communities proliferated, English gradually became the primary language of international business, banking, and diplomacy. Then came the 20th century and its burst of technology. Suddenly people were talking across oceans, flying across continents, hearing broadcasts that reverberated around the planet. Language spread faster than ever. The world wars carried American and British soldiers around the world, pollinating English as they went. When World War II ended, the English language was barreling (高速行驶) forward on the shoulders of American capitalism - McDonald's and Coca-Cola, Rambo and MTV, munitions (军火) and computer technology. Currently, about 80 percent of the information stored on computer systems worldwide is in English. Two-thirds of the world's science writing is in English, and English is the main language of technology, advertising, media, international airports, and air traffic controllers. Today there are more than 700 million English users in the world, and over half of these are non- native speakers, constituting the largest number of non-native users than any other language in the world.
