单选题Silas Minton"s funeral was a quiet 1 . It was 2 by the only 3 he had in the world, his niece and nephew, and by a few friends. The priest who 4 5 a hundred miles into this wild part of the county was now getting 6 for the simple ceremony. Minton, 7 "Minty" as his friends 8 call him, 9 a hard life 10 for gold in a lonely part of Western Australia. He had always refused to work in a gold mine 11 he believed that he could do better 12 his own. Although he was not a boastful (夸口) person, he had often declared that one day he 13 find a lump(块) of gold as big as his head and 14 he would retire and live in 15 for the rest of his life.

Two men now gently lifted the rough wooden box that 18 Minty"s body, but they almost dropped it when they heard a loud cry from the grave-digger. His spade (铁锹) had struck something hard in the rocky soil and he was shouting excitedly.

单选题Because we can feel that things are heavy, we think of weight as being a fixed quality in an object, but it is not really fixed at all. If you could take a one pound packet of butter 4, 000 miles out from the earth, it would weigh only a quarter of a pound. Why would things weigh only a quarter as much as they do at the surface of the earth if we took them 4 000 miles out into space? The reason is this: All objects have a natural attraction for all other objects; this is called gravitational attraction, but this power of attraction between two objects gets weaker as they get farther apart. When the butter was at the surface of the earth, it was 4 000 miles from the centre (in other words the radius(半径)of the earth is 4 000 miles). When we took the butter 4 000 miles out, it was 8 000 miles from the centre, which is twice the distance. If you double the distance between two objects, their gravitational attraction decreases two times two. If you treble(翻三倍)the distance, it gets nine times weaker(three times three). If you take it four times as far away, it gets sixteen times weaker (four times four)and so on.

单选题{{B}}B{{/B}} Many people like to watch TV. Watching TV is one of the most important activities(活动)of the day. TV brings the outside closer to people's homes. Some people say the world is smaller than before—because of TV. What's going on in the other countries? How do people live in places far away? Is there a good sports game somewhere? What's life in the deepest part of the sea. If you want to answer these and other kinds of questions, just turn on the TV. Turn it on and watch. You can see a lot and learn a lot. Of course, people can also learn through reading or listening to the radio. But with TV they can learn better and more easily. Why? Because they can hear and watch, too. TV helps to open our eyes. TV also helps to open our minds (思想). TV often gives us new ideas. We learn newer and better ways of doing something.

单选题In the desert world, the seasons differ from one region to another. The Gohi ,which lies roughly between 35℃ and 55℃ north of the equator, is a good example of seasonal change. Four seasons are characteristic of the Gobi: spring, summer, fall, and winter, with usually a false spring at the end of winter. These seasons are distinct, with extremes of temperature, as much as 150 between the hottest day in summer and the coldest day in winter. Spring in the Gobi usually begins about the second week April. For 2 or 3 weeks there is a period of delightful weather, with warm, sunny days and not too much wind. But these are the days of false spring. About the first of May, the tail end of winter returns, and cold, blustery days of dustburdened winds are the rule then, until early or middle June. The latter part of June, for 2 or 3 weeks after the blowy end of winter is the real spring. It spreads its rather comfortable warmth over the desert, and occasional light rains help the desert grass to come along nicely. July, or sometimes mid-June to mid-August is summer. Hot days are the rule, but the nights are cool. Wind and dust again govern the desert, but this is the season when hard rains, if they come at all, are most likely to dump water on the plains. Fall usually may be recognized by the encouraging, bright days beginning in mid-August and lasting until mid-September or the first of October. This is the time of year when both men and beasts feel best in the Gobi. The clear air, bright sun, and frosty temperatures make you glad to be alive. Winter comes with a rush anytime after the middle of September. One day you may be enjoying a pleasant temperature near the eighties. But suddenly the air cools. In a few hours the temperature has slipped below 50; and a little later cold rain changes to snow and blustering wind.
