Here are the results.We found that only fifteen percent of our students exercise every day. Forty-five percent exercise four to six times a week. Twenty percent exercise only one to three times a week. And twenty percent do not exercise at all!We all know that many students often go online, but we were surprised that ninety percent of them use the Internet every day. The other ten percent use it at least three or four times a week. Most students use it for fun and not for homework. The answers to our questions about watching television were also interesting. Only two percent of the students watch TV one to three times a week. Thirteen percent watch TV four to six times a week. And eighty-five percent watch TV every day! Although many students like to watch sport, game shows are the most popular.It is good to relax by using the Internet or watching game shows, but we think the best way to relax is through exercise. It is healthy for the mind and the body. Exercise such as playing sports is fun, and you can spend time with your friends and family as you play together. And remember, “old habits die hard”. So start exercising before it’s too late!Task 1 Fast Reading( )1.What kind of article is it?A. story B. diary C. survey2.

In northern China, corn and wheat (小麦) grow well in the dry weather. So the local people make steamed bread (馒头) and noodles from 6 or wheat. However, it is different in the 7 . There, lots of rain and land near lakes and rivers mean that people can grow and eat rice. The land and weather in Central America is 8 for growing cocoa trees.

When you get better, the headache gets better, too. If you’re not sick. other activities may cause a headache. For example, staying up too late, not eating a meal, or playing in the hot sun too long can set off a headache. Excitement about a special event or worries about something, a school exam, for instance, can also cause headaches. Some kids get headaches from riding in a car or bus or from straining (过度使用) their eyes by spending too much time watching TV or using a computer. Strong smells, such as perfume, smoke or the smell of a new car or carpet (地毯), can start a headache. Some food can cause headaches in some kids, such as bacon, bologna, and hot dogs. The caffeine (咖啡因) in sodas, chocolate, coffee, and tea may cause headaches, too. Kids don’t need caffeine, so it’s a good idea to control it in your diet. Sometimes no one knows why some people get headaches, but if you get them, the chances are someone in your family gets them, too. The headache is often inherited. In other words, it runs in the family.( ) 1. Which of the following activities may cause headaches? A. Eating too much B. Staying up too late. C. Eating breakfast D. Playing sports( ) 2.
