中考英语知识点解析：There be句子结构
be动词单复数的确定，看be后边第一个名词，当所接主语为单数或不可数名词时，be动词形式为is;当所接主语为复数名词时，be动词为are;当be动词后接两个以上主语时，be动词与最临近主语保持数上的一致。意思为"某地有某人或某物"。如：There is an eraser and two pens on the desk.桌子上有一块橡皮和两支钢笔。
There are two pens and an eraser on the desk.桌上有两支钢笔和一块橡皮。

(2)therebe句型的疑问句就是将be提到句首：Bethere+(any)+名词+地点状语

-No，there aren’t.没有。
(3)特殊疑问句：How many...are there(+地点状语)

There‘s one./There are two/three/some...
有时直接就用数字来回答。One./Two...

(4)如果名词是不可数名词，用：Howmuch+不可数名词+isthere+地点状语
