Why do earthquakes happen? Scientists explain that the outside of the earth is made of a number of different plates . For example, at San Francisco the Pacific Plate which is moving towards the northwest meets the North American Plate. The Pacific Plate is moving very slowly-at 5. 3 centimetres a year. Sometimes these two plates stop and do not move for years. Then suddenly, they jump and an earthquake is felt. As the movement of these plates, West America near the sea has always been a bad place for earthquakes. When the 1906 earthquake happened, the Pacific Plate jumped 5-6 metres to the north. We cannot stop earthquakes, but we can do things to make sure they don't destroy the whole of cities. First ,it is not a good idea to build houses along the lines, where two of the earth's plates join together. Second, if you think there may be an earthquake, it is better to build houses on rock not on sand. Third, you must make the houses as strong as possible. Weak buildings will fall down in an earthquake, but strong ones may stay up. We can't stop _ . A) earthquakes from destroying the whole of cities B) earthquakes C) building houses along the earthquake line D) building weak houses at San Francisco

To make Chinese students healthier and stronger, China's Ministry of Education has started a campaign. The campaign asks students to run every school day. Te campaign has started since October last year and will last until April this year. Kids at primary schools have to run 1km per day. It's 1.5kms for middle school students and 2 kms for high school and university students. And records will be set for every student. By the end of April 2009, a primary school student has to run 120kms in total/ A middle school students have to run 240kms by that time. Since the campaign started, people have had different ideas about it. Some people think it is good for students. They think the campaign can make students healthier. Some students have little exercise and the campaign can make them run. But some people don't think so. They think some schools don't have enough place for students to do running. If students have to run on the road, maybe it is not safe. They also think there are many ways to become healthier; running is not the only way. So they think the campaign is not a right decision. How many kilometers will a high school student run in total during the campaign? A) 120kms. B) 180kms. C) 240kms. D) 200kms.

Joan worked in a hospital as a nurse. One evening there was a big dance at the hospital. Most of the doctors and nurses would be there, but it was Joan's turn to look after the sick children. She liked dancing very much, so she felt very sorry for herself. She went to each sick child one after another and said good-night, until she came to one little boy, Dickey. He was eleven years old, but he was already able to talk like an adult( ). Poor Dickey had a very serious illness, and now he was hardly able to move any part of his body except his hands. Joan knew he would never get any better, but he was always happy and always thinking about other people instead of about himself. Dickey knew that Joan loved dancing, so now when she came to say good-night to him, he greeted her with the words, "I' m very sorry that you have to miss the dance because of us. But we are going to have a party for you. If you look in my drawer , you ' Il find a piece of cake. I saved it from my supper today, so it' s quite fresh. And there is also a dollar there, You can buy something to drink with that. And I' d get up and dance with you myself if I was able to," he added. Suddenly the hospital dance seemed very far away and not at all important to Joan. Joan felt unlucky that evening mainly because _ . A) there wasn't a dance ball at the hospital B) of her unpleasant job C) she couldn't look after the sick children D) she would miss the big dance
