There is not enough oil in the world now. As time goes by ,it becomes less and less ,so what are we going to do when it runs out? Perhaps we will go back to use horses ,carriages and bicycles .

 In the Second World War ,some people didn't use gas made from petroleum (石油)in their cars .They made gas from wood and plants instead . The cars didn't go fast ,but they ran ,so this was better than nothing. However, in the future, we can't cut down all our trees to make gas; we need our trees for other things, too.

Besides different types of gas, we can also use electricity(电)to run our cars but first we must make the electricity !Some countries have coal and they make electricity with that, but we might not always have coal, either. Other countries have big ,strong rivers and they can use the power of water to turn turbines(涡轮机) and make electricity more easily and cheaply.

We are also able to get power from the ocean tides. We put turbines into the mouth of the river .Then the tide comes in ,the water turns the turbines and then it goes out ,it turns them again.

Which of these ways will be used to run our cars in the future?

1.When might people have to go back to using horses and carriages?

A. When they are poor    

B. When they run out of oil

C. When they need more exercise

D. When there aren't any big trees in the world

2.How many ways are suggested to make electricity in the passage?

A.2           B.5          C.4                 D.3

3.The passage is mainly about             .

A. how to run our cars

B. what to do when oil runs out

Thirty years ago, Lake Ponkapog in Hartwell, New Jersey, was full of life. Many birds and animals lived beside the water, which was full of fish. Now there are few birds, animals, and fish. The lake water is polluted. It is in a colour of dirty brown, and it is filled with strange plants.

How did this happen? First, we must think about how water gets into Lake Ponkapog. When it rains, water comes into the lake from all around. In the past, there were forests all round Lake Ponkapog, so the rainwater was clean.

Now there are many homes around the lake. People often use the chemicals (化学制品)in their gardens. They use other chemicals inside their houses for cleaning and killing insects. There are also many businesses. Businesses use chemicals in their machines of shops. Other chemicals fall onto the ground from cars or trucks. When it rains, the rainwater picks up all the chemicals from home and businesses and then carries them into the lake . They pollute the water and kill the animals.

Boats on the lake are also a problem. Lake Ponkapog is a popular place for motorboats(汽船). But oil and gas from boats often get into the lake. So more bad chemicals go into the water this way.

People in Hartwell are worried . They love their lake and want to save it. Will it be possible? A clean lake must have clean rainwater going into it. Clean rainwater is possible only if people are more careful about chemicals at home and at other chemicals on the ground. And they mustn’t use motorboats any more on the lake. All these may change people’s lives. Only then can Lake Ponkapog be a beautiful, clean lake again.

1.In the past, the water in Lake Ponkapog was made clean by ________.

3.Cleaner rainwater will mean _________ .

A.more boats on the lake                   B.more dirty things in the lake

4.To save Lake Ponkapog, people need to ________.

A.be more careful about chemicals           B.use the water

C.grow fewer plants in the gardens            D.use more motorboats on the lake

5.The passage is about ________.

Ladies and gentlemen, I returned to this year in a time machine. In the year 2500, we are able to travel through time to any year in the history of the earth. This year is your last chance your lifestyle to save the earth.

  Beginning in the middle of the 20th century, a few people were worried about polluting the earth’s water and air, but most people did not change their way of life. Instead, they continued to pour(倒) dangerous chemical(化学物品) and other waste into lakes and seas, to drive more and more cars and trucks, and to cut down trees.

  By the year 2200, the earth’s water was completely polluted. People could no longer drink water, and they had to use other types of liquids(液体). Scientists said that in the future there might be too many people on the earth. But not enough was done.

  So by the year 2300, there were so many people that food became scarce. There was no water to grow food and all of the fish in lakes and seas died because of pollution. Terrible wars broke out between the rich and the poor. Scientists were working very hard to find another planet in space where humans could live.

  By the year 2400, the air was too polluted for humans to breathe. So we had to leave the earth. But only the rich were able to leave. Where did we go? Nowhere. And everywhere. You see scientists did not find another safe planet, so now we must travel around the universe in our space ships. We are still looking for a place to call our home.

  So it is up to you to change history. There is still hope. You must change your lifestyle now, before it is too late.

1.Which problem is NOT talked about in Paragraph 2?

A. Water        B. Air        C. Lifestyle     D. Food

2. The underlined word ‘scarce’ means ‘______’ in Chinese.

A. 昂贵的       B. 充足的       C. 缺乏的       D. 特殊的

3.Which of the following is NOT true?

A. Only a few people changed their lifestyle in the 20th century.

B. There was no clean water for people to drink by the year 2200.

C. All the fish died because of the pollution by the year 2300.

D. We found a new home in another planet by the year 2400.

4.What’s the best title of the passage?

Future and Today
It is well known that everyone has his own dream as well as his own future. But do you know what future really is? I have to say that future is now. That is to say we must treasure every minute now. If we want to have a bright future, we should know how important time is and use it well.
There is an old English saying:“Gain time, gain life”Then what’s time? Time is something that we can’t see or touch, but we can feel it passing by. Time is always with us. When we are at table, time passes; when we play, time goes by unnoticeably. We always say “Time is money”, but time is even more precious(珍贵的) than money, because when money is spent, we can earn it back. But if time is gone away, it will never return. So, some of us even say time is priceless.
We should always remember: future is now. For us students, we should try our best to work hard in order to create a great future of our own. We should make the best use of every hour and be the master of today. We should do everything before us as well as possible. And never put off what can be done today till tomorrow.
As we all know,“Time and tide wait for no man.”If you waste today, you will regret tomorrow. So from now on, work hard. Tomorrow will be better, and your future will be brighter. Remember:“No pains, no gains.”Today’s hard work is the cause of tomorrow’s harvest.
