Do you suppose Darwin, one of the greatest scientists of all time, really did foolish experiments? Or did he do experiments that were so simple and basic that other people just thought they were foolish?
Sometimes, people think they already know the answer to a question or the solution to a problem. Sometimes, they really do know an answer or a solution, but without thinking they are important.
Charles Darwin didn’t settle for(满足于)just thinking he knew something. And, he believed all things could be important however simple they seemed to be.
Suppose you drop sheets of paper that are of exactly the same size and shape. If you drop them at the same time in the same place, they will fall in the same way. Now make one of the sheets of paper into a tight little ball and let it drop along with the other sheets. What happens? You have done an experiment that is so simple that you might think it couldn’t be worth anything.
But this simple experiment is important. It explains part of our present-day understandings of physics, ideas that were worked out long ago by Galileo and Newton. And these understandings set aside some of ancient Greek physics.
Scientists sometimes stop to look at very simple things and to think very hard about them. Even the simplest idea, which we might think is foolish, can shake the foundations of science.

Some countries have a large number of earthquakes. Japan is one of them, while others do not have many, for example, there are few earthquakes in Britain. There is often a great noise during an earthquake. The ground vibrates (颤动).Houses fall down. Railways are broken, which causes trains to turn over. Sometimes thousands of people are killed in different ways. About 60,000 were killed in 1783 in the south of Italy. Some people say that earthquakes often happen near volcanoes(火山), but it is not true. The centers of some earthquakes are under the sea. The bottom of the sea suddenly moves. The powerful forces inside the earth break the rocks. The coast is shaken and great waves appear. These waves travel long distances and rush over the land when they reach it, breaking down houses and other buildings. Sometimes they break more buildings than the earthquake itself.
A terrible earthquake happened in Assam, India, in 1986.The land near Shillong suddenly moved 1.5 feet to one side, and then back again. It continued to act like this 20 times a minute. Few buildings could stand what was happening and the great stones flew four feet up into the air. What kind of building stays up best in an earthquake? The Americans carefully studied the results of the earthquake at San Francisco(1906) and believed it best for buildings to be made with concrete(混凝土) walls together by steel frames. Such are the buildings that can't burn or fall easily.
1.Which of the following is NOT true?
A. Trains' turning over is directly caused by the earthquakes.
B. Some earthquakes have their centers under the sea.
C. It isn't certain that earthquakes happen near volcanoes.
D. Buildings with concrete walls are better against earth quakes.
2.Earthquakes often happen .
A. near volcanoes B. Both A and D
C. in Britain D. in Japan
3.___________ make(s) more loss than the earthquake itself.
A. Nothing
B. Volcanoes
C. Forces inside the earth
D. Terrible waves by the earthquake
4.When an earthquake happens, ____________can be heard.
A. trains B. thousands of people
C. a great noise D. the powerful forces
If you go into the woods with your friends, stay with them. If you don’t, you may get lost. If you do get lost, this is what you should do.
Sit down and stay where you are. Don’t try to find your friends — let them find you. You can help them to find you by staying in one place. There is another way to help your friends or other people nearby to find you. Give them a signal by shouting or whistling three times. Stop. Then shout or whistle three times again. Any signal given three times is a call for help. You will be helped by others. Keep up the shouting or whistling, always three times together. When people hear you, they will know that you are not just making noise for fun. They will let you know they have heard your signal. They will give two shouts, two whistles or two gunshots. When a signal is given twice, it is an answer to a call for help.
If you don’t think that you will get help before night comes, try to make a little house and cover up the holes with branches with lots of leaves and grass.
What should you do if you get hungry or need to drink some water? You should have to leave your little branch house to look for a brook. Don’t just walk away. Pick off small branches and drop them as you walk so that you can find your way back. The most important thing to do when you are lost is — stay in one place.
1.How do you let people believe that you are not just making noise for fun?
A. Stop now and then.
B. Go on shouting or whistling.
C. Shout over and over at the top of voice
D. Shout or whistle three times once a while.
2.If nobody answers you after your signal, what should you do then?
A. Give two gunshots. B. Shout louder.
C. Stop shouting. D. Make a house.
3. If you feel thirsty when you are lost in the forest, what should you do?
A. Go and find a brook.
B. Light a fire and make yourself some tea．
C. Go to find a brook and leave marks behind you.
D. Find something to hold the water.
4.What’s the best title for the passage?

As it is known to us, fewer and fewer students do sports regularly, what makes them weak and easily tired.
There are many reasons about this. First of all, some of the students complained that they have too many homework, resulting in less time to take exercise. Beside, some of them think that it is very difficulty for them to keep doing exercise, because it is a very hard thing.
Because lack of physical activities, many students are in poor health. I suggest that our school must take measures to encourage more students to take part in sports. For us students, no matter what busy we are, it is necessary to spare some time to do exercise.
