第二部分 阅读理解 Passage 1 Cars are a lot of fun, but they could also be dangerous. We have to be careful when we drive them or ride in them. It’s always a good idea to put on your seat belt when you’re in a car. Why? Think about this example: you put an egg on a skateboard and give it a push. If the skateboard hits a stone, it will stop, but the egg won’t. It will fly through the air, hit the ground and break. Now, think what would happen if you tied the egg to the skateboard. When the skateboard hits a stone, the egg won’t go flying, it will stay safely on the skateboard. Volvo, a famous Swedish car maker, was the first to use seat belts in 1849. Air bags are also very important for car safety, because sometimes a seat belt isn’t enough. If the car is going really fast and runs into something, seat belts could even hurt the people who wear them. Most newer cars have air bags in front of and next to the seats. When a car hits something, its air bags will come out quickly – in less than one second – to keep the people inside safe. 6. The passage mainly tells us ________. A. how seat belts work to make cars safe. B. why we must tie the egg to the skateboard C. two important ways to keep safe in cars D. what air bags are 7. The writer gives the example of the egg to ________. A. show why it is important to wear a seat belt when in a car B. tell us what a skateboard is C. show how to wear a seat belt D. tell us that eggs are easy to break 8. Seat belts can make cars safer because ______ A. they are made of strong materials B. they can stop us from hitting other cars C. they can help us stay safely on the seats D. people are interested in them 9. Air bags are also important for cars because they ______ A. are made of plastic B. work together with seat belts to keep us safe C. are put in front of and next to the seats D. can stop cars hitting each other 10. The best title for this passage is _______ A. Useful Seat Belts B. Make Yourself Safe in Cars C. Air Bags Work Well D. Egg on Skateboard

Passage Two What makes a person a scientist? Does he have ways or tools of learning that are different from those of others? The answer is “no”. It is not the tools a scientist uses but how he uses these tools that make him a scientist. You will probably agree that knowing how to use a tool is important to a carpenter. You will probably agree, too, that knowing how to investigate, how to discover information, is important to everyone. The scientist, however, goes one step further, he must be sure that he has a reasonable answer to his questions and that his answer can be confirmed by other persons. He also works to fit the answers he gets to many questions into a large set of ideas about how the world works. The scientist’s knowledge must be exact. There is no room for half right or right just half the time. He must be as nearly as the conditions permit. What works under one set of conditions at one time must work under the same conditions at other times. If the conditions are different, any changes the scientist observes in a demonstration must be explained by the changes in the conditions. This is one reason that investigations are important in science. Albert Einstein, who developed the theory of relativity, arrived at this theory through mathematics. The accuracy of his
