Therebe用法全解.doc

There be用法必记 There be表示 “存在有”,即当我们告诉某人某事存在(或不存在)常用这种结构。其中there是引导词,本身无词义;be为谓语动词,后面跟的是名词,也就是主语,也就是说there be结构的运用也就是倒桩的具体运用。其真正的主语在there be 之后。在新课标中对此的考试要求是：掌握There be句式的结构特征和基本用法。在我们的课本中也出现了大量的There be句式如： There are a few simple safe measures to follow while training.(Book3,P51) There are also records of gymnastics being performed in China and some other Asian countries.(Book3, P50) In China, there is only 7% of the land used for growing crops, which feeds more than one fourth of the world population.(Book3, P20) If the population keeps growing so quickly, there will be only standing room left for us next century.(Book2A, P49) There were lots of good English language programs broadcast on TV or on the radio in China.(Book1A, P46) There be结构是如此重要，我们高中生必须对此从以下方面进行了解。 一、 注意事项： 1. 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. 在教室里有一些学生和一位老师。 There is a teacher and some students in the classroom. 在教室里有一位老师和一些学生。 2. 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。 3. 该结构的主语有两个概念结构上there是主语,主谓一致上后边的名词是主语 4. 反意疑问句,. 助词+there? 助词根据谓语的形式判断 There was a knock at the door, wasn’t there? There happened to be a man walking by, didn’t there? 二、 结构变形： 在there be 结构中还可把be 改变从而使得there be结构有了一些改变具体总结如下： 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. 可以和情态动词连用; There might be snow at night.晚上可能有雪。 There shall be an agreement on the date3. 可与形容词或动词连用，常见的有：seem to be/happen to be/be going to be/used to be/be likely to be
