One possible version:
My American friend’s school starts at 9:00 a.m. and finished at 4:00 p.m. They have lunch at school. After lunch, they chat with each other. Sometimes they listen to pop music. They have a lot of time to do after-school activities. There are twenty-five students in each class. They don’t have to wear uniforms. There is a library in their school. They often go there to read or borrow books. They also have a big football field and a swimming pool. They don’t have much homework. They only have to spend half an hour on homework every day.
这是以提纲提供情景的作文。这种形式本身的要点已经很明确，重点也很突出，只要把各个提纲加以发挥，注意遣词造句的灵活性和语法规则的正确性，就不会造成审题不清而偏离主题，但要注意，文章必须覆盖所提供的各个提纲的要点。为了保证文章层次分明、条理清楚，要把时间固定下来，;写经常发生的事或对人物的描写，要用一般现在时。整个文章中的人称要一致，首尾呼应，不要随意改动，以免造成误解。
