II. Grammar: ?一般将来时 ?there will be ?few,a few,little,a little,much,many 语法小结: 语法小结: 一、一般将来时
  1.用 be doing 表示将来:主要意义是表示按计划、安排即将发生的动作,常用于位置 转移的动词。 如:go,come,leave,arrive 等,也可用于其他动作动词。 We are having fish for dinner. We are moving to a different hotel the day after tomorrow. 这种用法通常带有表示将来的时间状语,如果不带时间状语,则根据上下文可表示 最近即将发生的动作。 A: Where are you going? B: I am going for a walk. Are you coming with me? A: Yes,I am just coming. Wait for me.
  2.用 be going to do 表示将来:主要意义,一是表示“意图”,即打算在最近的将来或将 来进行某事。 Are you going to post that letter? How long is he going to stay here? I am going to book a ticket. 另一意义是表示“预见”,即现在已有迹象表明将要发生或即将发生某种情况。 It’s going to rain. George is putting on weight; he is going to be quite fat.
  3. 用 will/ shall do 表示将来: 主要意义,一是表示预见。 You will feel better after taking this medicine. Do you think it will rain? 二是表示意图. I will not lend the book to you. Take it easy,I will not do it any longer. 基本结构: She will come to have class tomorrow. Will she come to have class tomorrow? She won’t come to have class tomorrow.
What will she do tomorrow? 二、There be 结构
  1. there be 结构中的 be 是可以运用各种时态的。 There is going to be a meeting tonight. 今晚有个会议。 There was a knock at the door. 有人敲门。 There has been a girl waiting for you. 有个女孩一直在等你。 There will be rain soon. 不久天就要下雨了。
  2. 动词 be 单复数形式要跟 there be 之后的真正的主语一致。并且要根据就近一致原则 来变换 be 的单复数形式。 如 There is a book on the desk. 课桌上有一本书。 How many people are there in the city? 这个城市里有多少人口? There is a pen and two books on the desk. 课桌上有一个钢笔和两本书。 There are two books and a pen on the desk. 课桌上有两本书和一个钢笔。 There are some students and a teacher in the classroom.教室里有一些学生和一位老师。 There is a teacher and some students in the classroom. 教室里有一位老师和一些学 生。
  3. 在 there be 引起的句子结构中,用来修饰主语的不定式主动形式和被动形式均可。 There is no time to lose (=to be lost). 时间紧迫。 There is nothing to see (=to be seen). 看不见有什么。 There is nothing to do. (=to be done) 无事可做。
  4、There is no doing. (口语)不可能……. There is no telling when he will be back. 无法知道他什么时候回来。 There is no knowing what he is doing. 无法知道他在做什么。 三、课文难句解析

  2. There will be less leisure time.空闲时间会更少。
