题目内容

Today, the forests have almost gone. People must ________ down too many trees.


  1. A.
    stop to cut
  2. B.
    stop from cutting
  3. C.
    be stopped to cut
  4. D.
    be stopped from cutting
D
解析:
本题考查被动语态的用法。最具迷惑性的选项是A,不少同学们只记得stop之后可接动词不定式。殊不知如果此处用不定式,则作目的状语,句意变为:人们必须停下来去砍伐树木。很明显其错误,排除A;句子的真正意义为:当今,森林几乎没了,必须要阻止人们砍伐太多的树木。这样,我们不难记起stop sb. from doing sth.这个固定搭配,且本题应使用被动语态。

There have been many great inventions or things that changed the way we live. The first great invention was the one that is still very important today——the wheel. This made it easier to carry heavy things and to travel long distance.
For hundreds of years after that there were few inventions that had as much effect as the wheel . Then in the early 1800s the world started to change. There was little unknown land left in the world. People didn’t have to explore much any more. They began to work instead to make life better.
In the second half of the 19th century many great inventions were made. Among them were the camera, the light and the radio. These all play a big part in our daily life today.
The first part of the 20th century saw more great inventions. The helicopter in 1909, movies with sound in 1926, the computer in 1928, jet planes in 1930. This was also a time when a new material was first made. Nylon came out in 1935. It changed the kind of clothes people wore.
The middle part of the 20th century brought new ways to help people get over diseases. They worked very well. They made people healthier and allowed them to live longer. By the 1960s most people could expect to live to be at least 60.
By this time most people in developed countries had a very good life. Of course new inventions continued to be made. But man now had a desire(渴望) to explore again. The earth was known to man but the stars were not. Man began looking for ways to go into space. Russia made the first step. Then United States took a step. Since then other countries , including China and Japan, have made their own steps into space.
In 1969 man took his biggest step away from earth. Americans first walked on the moon. This is certainly just a beginning, though. New inventions will some day allow us to do things we have never yet dreamed of.
