Scientists study the world and learn about things using a process called the scientific method(方法). By asking important questions and   16  the answers, it is possible to make amazing discoveries! Sometimes a scientist is   17  to answer his own questions, but if he has taken good notes another scientist may come along later who is able to use new knowledge to answer it.

When you use the scientific method to   18  an experiment, you start by making observations(观察) about something that  19  you. Based on your observations, you make a hypothesis. This is using  20  you know to make a smart guess about what you think could happen. Then you are ready to begin your experiment. All   21  your experiment you take down notes, which are   22   experiment date(资料). You are constantly making observations during this time. You may make discoveries that cause you to improve your experiment as you go.   23  , you conclude your experiment and begin to look over your notes to decide what it all means. Based on what you have learned, you make a final statement about   24  your hypothesis was correct or not. You have to have reasons and evidence to support what you are saying.

Using the scientific method can be difficult, but rewarding. Because all the steps are organized in a process, the   25  are more valid(可信的). When you provide observations as evidence to support what you are saying, your ideas are more likely to be accepted.

It was a village in India. The people were poor but they were happy. After all, their forefathers had lived in the same way for centuries.

Then one day, some visitors from the city arrived. They told the villagers there were some people elsewhere who liked to eat frog. However, they did not have enough frogs of their own, and so they wanted to buy frogs from other places.

This seemed like money for nothing. There were millions of frogs in the fields around, and they were useless to the villagers. What they had to do was to catch them. Agreement was reached, and the children were sent into the fields to catch frogs. Every week a truck arrived to collect the catch and hand over the money. The villagers were able to dream of a better future. But the dream didn’t last long.

The change was hardly noticed at first, but it seemed as if the crops weren’t doing so well. More worry was that the children fell ill more often, and there were more insects around lately. The villagers decided that they couldn’t just wait to see the crops failing and the children getting weak. They would have to use the money earned to buy pesticides (杀剂) and medicine. Soon there was no money left.

The people realized what was happening. It was the frog. They hadn’t been useless. They had been doing an important job--- eating insects. Now with so many frogs killed, the insects were increasing more rapidly. They were damaging the crops and spreading diseases.

Now, the people are still poor. But in the evenings they sit in the village square and listen to sounds of insects and frogs. These sounds of the night now have a much deeper meaning.

In order to know a foreign language thoroughly, four things are necessary. Firstly, we must be able to understand the language when we hear it spoken. Secondly, we must be able to speak it ourselves, correctly, with confidence and without hesitation. Thirdly, we must be able to read the language and fourthly, we must be able to write it. We must be able to compose（组成）sentences that are grammatically correct. We must know how to arrange sentences in paragraphs, so as to write a good letter or composition.

There is no easy way to succeed in language learning. A good memory is of great help, but it is not enough simply to memorize rules from a grammar book. It is not much use learning by heart long lists of words and their meaning. We learn words not by ourselves, but in sentences. We must learn by using the language. “Learn through use” is a good piece of advice for those who are studying a new language. Practice is very important. We must practice speaking and writing the language whenever we can.

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

C. different types of gas
