    题目列表(包括答案和解析)

    Then one day, a wind picked him up and threw him on an open field under the sun．Later, he was given rain．

    Years later he saw a traveler sitting by his side．“Thank God for this．I really need some rest,” he heard the traveler say．

    “Yes! Why else do you think people come here?”

    “What do they come here for?”

    “To feel your shade （树荫）! Don’t tell me you didn’t know you had grown over time．”

    A moment passed before the traveler’s words brought him pride．

    The seed thought and smiled for the first time in his life．The years of torture （折磨） by the sun and the rain finally helped him grow up．

    　　Doctors tell us not to smoke, but a lot of people smoke tobacco every day．Long ago, no one in Europe smoked; the tobacco plant was unknown there．It grew in America, and Christopher Columbus found it there．Later, he returned to Europe and told everyone about tobacco．He said that the American Indians often smoked it．Sir Walter Raleigh was a famous man in the days of Queen Elizabeth I．He traveled widely and learnt to smoke．Then he returned to England, but he did not stop smoking．He used to smoke two pieces every day secretly in his room．When someone came in, he quickly hid his pipe; but one day, he was not quick enough．A man came in and found clouds of smoke in the room．More smoke was coming from Raleigh's mouth, so the man got some water and threw it over Raleigh．He believed that Raleigh was burning．He ran out of the house and told everybody about it．After this, smoking was not a secret．Raleigh told Queen Elizabeth I about it．He added that he could weigh his smoke．She did not believe this, and she asked him to explain．．

    　　“First,”he said,“I shall weigh the tobacco．Then I shall put it in my pipe and smoke it, then I shall weigh the ashes which remain．I can take them out of the pipe and weigh them on a balance．There will be a great difference between the two weights．The tobacco must be heavier than the ashes．The difference between them must be the weight of the smoke．

    　　It was a good explanation：but Raleigh was wrong．When his tobacco burned, it did this, but the oxygen was not in the tobacco at the beginning．It was added when Raleigh smoked his pipe．So the smoke was heavier than the difference between the two weights．The weight of the oxygen was added．

    　　A good friend of mine was complaining about her son the other day．“Did you notice,” she started, “how he didn't wait for me to get my salad before he dived into his?”

    　　True enough, the boy attacked his plate faster than a cat in the wild．Without manners, we're no more than animals．Actually, that's not true, I've been watching and feeding a group of wild cats, and they show unusual politeness toward each other．Even when food is scarce, they take turns, leaving at least a small part for the next in line．

    　　My mother educated her three children to have good manners all the time．We were made to feel very uncomfortable as if we were sitting on pins and needles until we got used to saying please, thank you ,pardon me, and I'm sorry．And I have to say, while it was a painful learning experience, it was one of the most valuable．

    　　I can't tell you how often I sat with my friends, eating at their dinner tables, and their parents thought highly of my good manners．While it was a little embarrassing, I knew even then that my mother's teachings were paying off．

    　　Many years later, when I was attending seminars across the country, my manners were quite useful．

    　　While I regret that I haven't been a perfect example, I'm still working on it．I suppose, in this regard, my mother lives on through me, I didn't have her beautiful singing voice or her green eyes, but she did make sure I received one of her finest characteristics．

    阅读下列短文，从每题所给的四个选项(A、B、C、D)中选出最佳选项。

    　　Radar is very important in aviation (the aircraft industry) today. It was first introduced in the Second World War. The British used it in the great air battles over England in 1940．The British fighter planes had to be in exactly the right place at exactly the right time to meet the enemy bomber(轰炸机). In order to get there, the fighter stations had to be warned long before the bombers actually appeared. They also had to know the course the bombers were following. This would have been impossible without radar.

    　　The Germans also used radar later in the war when the great air raids (袭击) against their cities began. On both sides the system was almost the same in a number of ways. The heart of the radar warning system was the “operations centre”. This was a huge system of rooms, usually below the ground. Radar showed the position of the enemy bombers while the bombers were still far away. In the centre of the main operations room there was usually a huge map on a large table. The position of the bombers was also shown on this table. Anybody who looked at it could see immediately where the bombers were at that moment. The people in the radar centre also had to decide where the bombes were going, or what the likely targets (目标) were. When this had been calculated the people in those places were warned. As they hurried to air raid shelters below the ground, fighter planes were taking to the air. The fighters were never out of radio contact (联络) with the radar centre.

    　　At night, radar was a pair of eyes that guided the fighters to bombers that they could not see. A radar controller on the ground told the pilot exactly where to go. Usually the pilot himself did not see the bomber until he was a few seconds away from it. Then he would open fire. None of these thing could have happened without raday.

    1．Radar was used by the British in 1940 to ________.

    [　　]

    A．guide bombers to their targets in the daylight

    B．get fighters away from other British fighters they could not see

    C．guide fighters to the right place in order to meet the German bombers

    D．guide bombers to their targets at night

    2．The Germans began to use radar ________.

    [　　]

    A．earlier than the British

    B．later than the British

    C．after the Second World War

    D．almost at the same time as the British

    3．An air raid shelter is a place where people ________.

    [　　]

    A．shoot at bombers

    B．hide from bombers

    C．keep bombs

    D．keep radar

    4．Radar helped night fighter pilots to ________.

    [　　]

    A．see bombers long before they could do without it

    B．get close to the bombers before they could see them

    C．open fire on bombers that they could not even see

    D．get back to the fighter station after the battle
