一、课文重点知识
（一）.There be 句型的用法：
1.be可以有现在时（there is/are）、过去时(there was/were)、
2.主谓一致
There be 结构中的be动词，主语是不可数名词或单数可数名词时用is（过去时用was）,是复数时用are(过去时用were)。

如:
There is a flower in the bottle. 瓶里有一朵花。

主语是单数
There is some money in the purse. 钱包里有些钱。

主题是不可数名词
There are some students in the classroom. 在教室里有一些学生。

主语是复数
（3）There be 结构的句型转换 (注意时态)
3. 否定句: there be的否定式通常在be后加not构成(在口语中be时常与not缩写在一起)。

如果句中有some,一般要变成any。

如:
There are some children in the picture.
There aren't any children in the picture.
There is a flower in the bottle.
There isn’t a flower in the bottle.
There was a park in our town fifty years ago.
There wasn’t a shopping mall in our town fifty years ago.
There were some funny trains one hundred years ago.
There weren’t any planes two hundred years ago.
4.. 一般疑问句及其答语:把be提到there前,首字母大写,句末用问号即可。

其肯定答语是Yes, there is / are. Yes,there was/were
否定答语是No, there isn't / aren't. No,there wasn’t/weren’t
如: -Are there two cats in the tree? -Yes, there are. (No, there aren't.)
（二）ago常用于一般过去时，表示….以前,请根据中文翻译英文：
十天前十年前
3.or表示选择，意为“或”“还是”
1.My grandma is old, _______she is very pretty.
2.Jack is cheerful_______handsome.

4.You are kind_______generous.
5. The students _______ the teachers are planting trees now.
