    Last week we held a discussion on which we should do for our school before we graduate．The students in our class have different suggestion．Some students thought that we can collect money to buy some books for the school library or everything else for the school．Other students argue that there's not necessary to spend money．We can study hard and make our school feeling proud of us．

    Most people in the United States don't learn to speak the second language. High schools teach languages. And very few students learn to speak good. Why don't Americans speak other languages? The United States are a very large country. Americans can travel a long distance and not leave the United States. They do not need learn a second language. And many people in other part of the world spoke English. If Americans travel to other countries, they can speak English in here, too. But some Americans think that is a mistake to speak English only. They believe it is very importantly to learn a second language.
