The world is not only hungry but also thirsty for water. This may seem strange to you, since nearly 70% of the earth’s surface is covered with water. But about 97% of that is sea water or salt water. Man can only drink and use the other 3% of fresh water from rivers, lakes, underground and so on. And we can not even use all of that because some of it has been made dirty.

Earth Day is April 22. But on all other days, we must also remember how important water is. The water that we use is the most important natural resource on the earth. Today we face serious water problems. One of them is water pollution. All kinds of things from cars, factories, farms and homes make our rivers, lakes and oceans dirty. Polluted water is very bad for people to drink. And dirty water is bad for fish, too.

How do cars and factories make our water dirty? First they pollute the air. Then when it rains, the rain water makes our drinking water dirty. Dirty rain, called acid rain is also bad for plants, animals and buildings. Scientists say that in 30 years, more than half of the people in the world won’t have enough clean water. We have to learn how to stop wasting water. One of the first steps is to develop ways of reusing it. Today in most large cities, water is used only once and then sent out into a sewer system (下水道). From there it returns to the sea or goes underground.

But even though every large city reused its water, we would still not have enough. So we should make use of sea water by removing the salt in it. If we can take these steps, fresh water won’t be used up.

1.The world is thirsty for water because _______.

A. we don’t have enough fresh water      B. a lot of water goes into sewer systems

C. only 70% of the earth’s surface is water                  D. sea water is widely used rather than fresh water

2.From this passage, we know acid rain _______.

A. is only bad for living things       B. is not bad for buildings and factories

C. can be produced in factories        D. is bad for people, animals, plants and buildings

3.One difficult way we can solve the problem is to _______.

A. use the water with salt in it           B. remove the salt from sea water

C. get water from underground              D. reuse the water in cities

4.What is the best title for this passage?

A. Fresh water and sea water               B. A thirsty country

C. The importance of water  D. The world’s water problem

We can not live a modern life without traveling. The fastest way of traveling is by air. With a plane

one can travel in one day to places which it took a month or more to get to a hundred years ago. 

Traveling by train is slower than by plane, but one can see the country he is traveling through. 

Modern trains have comfortable seats and dinning-cars. They make even the longest journey enjo

yable.

Some people prefer to travel by sea when possible. There are large luxury liners or river boats

.They are not as fast as trains or planes, but traveling by sea is a very pleasant way to spend a holi

day.

Many people like to travel by car. They can make their own timetable. They can travel hundred

Studying in groups is becoming more and more popular in class. It has many advantages. For example, we can not only save time but also encourage each other when we study in groups.

I still remember when I was in Grade 8, my physics was very poor. I had a really hard time with it. Once in class, the teachers asked us to discuss it with each other, but I was very shy, I could not do it like what they told me. My physics teacher encouraged me to face others and talk with someone else bravely. Then I studied with some classmates together. When I did not understand any questions, they could give me some advice, I could quickly find out the ways to deal with the problems. After that, I felt very relaxed and asked my classmates a lot of questions about physics. I did not feel stressed out at all. At last, I finished my homework by myself for the first time. How excited I was!                 

Because of studying in groups, I am not worried about physics any more. With my classmates’ help, I get more confidence. It also gives me more chances to improve myself in many ways.

  It is well known that Albert Einstein was one of the greatest scientists of all time and he was also a really great person. Here are some interesting things about him.

     When Einstein started to work in America, someone asked him what he needed. He said he needed a desk, some paper and a pencil. He also asked for a big waste-paper basket to hold all of his mistakes. This shows that he knew even the cleverest man in the world can only learn by making mistakes.

     Einstein regarded time as very important. He never wore socks and he thought putting on socks was a waste of time as people already wore shoes. He also thought it was a waste of time remembering things that could quickly be found in a book. That's why he never remembered his own phone number, which was in the phone book. He knew what was worth remembering. It is true that if we are going to do great things in our lives, we can not waste our time.    

     Einstein liked to joke too. Once in an exam a student asked him why all the questions were the same as last year's. Einstein replied the questions were the same but the answers were different!
