话说There be句型

南昌十九中  宋焘

There be句型是中学阶段必须掌握的重点句型，其用法总结如下。

一、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.。

There was a knock at the door.

There has been a girl waiting for you.

There will be rain soon.

二、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.   

There is a pen and two books on the desk.

    There are two books and a pen on the desk.

三、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。

四、在there be的 be 前还可以加上各种情态词，如：

There must be something wrong.一定有问题。

There ought not to be so many people.不应该有这么多的人。

There might still be hope .可能还有点希望。

五、一些特殊的表达方式：

１There is no sense in doing 做某事是没有用的，没有意义的

There is no sense in making him angry  

There in no sense in going alone.

2 There is no use /good doing 做某事是没有用的，没有必要的

3 There is no need to do 没有必要做某事
