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?

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 (得到) time, gain life.” Then what’s time? Time is something that we can’t see or touch, but we feel it passing by. Time is always with us. When we are at table, time passes; when we play, time goes by unnoticeable. We always say “Time is money”, but time is even more precious (珍贵的) than money, because when money is spent, we can make it back. But if time is gone away, it will never return. So, some of us even say time is priceless (无价的).

  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 (推迟) 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.
