7年级上册的重点句型,如：there.......be

现在时：there is/are 过去时：there was/were
eg:There is a book on the desk.
There are many books on the desk.

There was a girl in the classroom.
There were many girls in the classroom.

"There be"是英语中最常见的又是非常重要的句型,它是表示"存在" 的一种基本方式,其句型结构通常为:There be + sb./sth. + somewhere/doing sth.但作为英语教师,仅仅知道这点用法还远远不够,"There be"还有更多较为特殊的用法。下面笔者想通过例子来共同商榷。

我们都知道 "There be" 后面可跟一个名词或动名词,请看下面例句:

1. There is a shop at the corner, where you can buy fruits.

在拐角处有家商店,你可以在那里买水果。

2. There is no knowing what may happen tomorrow.

谁也不知道明天将发生什么。

同时,我们也可以根据表达的需要,在There与 be之间用上恰当的情态动词can,may,must,should,will等,构成:There will /may/must/can,etc. be... 请看:

1. There will be another bridge across the Yellow River with the quick development of the economy of China.

随着中国经济的飞速发展,黄河上将有另一座桥。

2. There must be some rules for the changes.
