题目内容

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.

1.This passage talks mainly about _______________ .

Dear Linda,
I have been in England three months now, and it’s my first time to be here. I hope you don't think I've forgotten you. There have been so many places to see and so many things to do that I've not had much time for writing letters.
I shall soon be starting my studies at King's College. So far I've been learning about England and British ways of living. I won't tell you about London. There are plenty of books you can read and plenty of pictures you can look at. I'm sure you'll be more interested to know what I think about the life here.
I find some of the customs (风俗) new and interesting. People here do not shake hands as much as we do in Europe. During the first few weeks I was often surprised because people did not put out their hands when I met them. Men raise their hats to women but not to each other.
Yours
Alice

Everyone tries to get to school on time. But when bad weather gives you trouble, can you still make it before the bell rings?

In northern China during spring, big sandstorms often make trouble for students and everyone else. When the sky is dark with sand, buses and cars all move much more slowly. Sometimes, people can’t even see for 20 metres.

Sandstorms usually happen in spring. This year, sandstorms started in late March. They have happened in more than 10 provinces (省)  in northern China this year. More than 70 million people have had problems in those places because of the sandstorms.

People in southern China don’t have to worry about this kind of bad weather. Most of the sand comes from Gansu and Inner Mongolia(内蒙古). In northern China, lots of places have few trees and don’t get much rain. People there have been cutting down too many trees. When there aren’t many trees, the ground can’t keep enough water. Over the years, the ground dries up and turns to sand. When spring comes and the ice melts(融化), the ground becomes looser(更松散的). Strong winds take the loose sand into the sky.

Sandstorms are bad for people’s health. If people breathe(呼吸) too much sand, they could cough or have asthma(哮喘).

Sandstorms also give farmers lots of problems. Sometimes their sheep get lost in the storms and never get back home. The winds also tear down farmers’ houses.

What can you do to stop sandstorms? Here’s an idea: Ask you parents to help you plant some trees this spring.

If you see people cutting down too many trees, tell them about the dangers of sandstorms, and ask your government to stop them from cutting.

1.In which season do sandstorms usually happen?

A.In spring.

B.In summer.

C.In autumn.

D.In winter.

2.Which of the following provinces in China is often hit by sandstorms?

A.Fujian Province.

B.Yunnan Province.

C.Jiangsu Province.

D.Gansu Province.

3.The underlined phrase “tear down” in the sentence means “_________”.

A.使……哭泣

B.弄倒

C.摧残

D.加固

4. According to the passage, what cannot be caused by sandstorms?

A.Health problems.

B.Traffic problems.

C.The loss of farm animals.

D.Noise pollution.

5.Which is not stated in the passage?_______________ .

A.Trees can help keep enough rain water

B.More trees need to be planted

C.Some people are doing harm to the environment
