there be句型结构
1、There be句型中的be应和其后出现的补充
语在数上一致，即“就近原则”，如：
There is a lamp on the table.
There are some apples in the bowl.
There are five books,two pens and a ruler in the school bag.
There is a ruler,two pens and five books in the school bag.
2、如果补语是复数名词，却表示一笔金额或一个总数或表达一个单个概念时，则仍用单数be形式，如：
There is five hundred dollars to pay.
There is still another 20 miles to drive.
There is duck and green vegetables for supper.
3、There be 中的be 有时可以是lie,stand,used to be,seem to be,appear to be 等，如：
There lies a river to the south.
There lived an old man in the small house.
There stood a temple near the river.
There used to be a castle at the foot of the hill.
4、There is(was)+not +doing结构相当于It is(was) impossible to +动词原形，如：
There is not going home. =It is impossible to go home.
There is not living with him.=It is impossible to live with him. 。
There is not knowing what may happen. =It is impossible to know what may happen
