　　九、阅读与表达
    Several years ago, cell phones were very expensive. Only important people and people with a lot of money had them. These days, the prices have been greatly falling, and they become in small sizes and different colours. So more and more people love using them, even high school students, have one in their hands.
    It is true that it's an easy way to keep in touch with (联系)friends at any time and in any place. But in places like classrooms (They are not allowed to bring into school because some students won't listen to the teacher carefully.)，movie theatres, and museums, where everyone should be quiet or talk in low voice, we can also hear the ringing. That's very bad. Some drivers have accidents (事故)for using cell phones when they are driving. Worst of all, some students who can't pay their phone bills do something illegal (违法的)to get money. So, are cell phones really a help?

    拓展探究
    一、1.be going to的用法点拨
    be going to是一种固定结构，它后面要接动词原形，用来表示按计划或安排要发生的动作，有时也可以表示推测将要或肯定会发生的动作，有“准备;打算”的意思。含有be going to结构的句子中往往有表示将来的时间状语。例如：
    We are going to have a class meeting this afternoon.今天下午我们打算开班会。(安排)
    Look at the black clouds .It's going to rain.看那些乌云，快要下雨了。(推测)
