there be句型与have/has的区别
重要句型there be +名词+ding+介词短语
there be句型是一个表示“存在”的句型，它是主语在be动词后面的倒装句。there be句型结构：There be(is，are，was, were )+主语+地点状语。某处有(存在)某人或某物
主谓一致性1. 主语是单数或不可数名词，be动词用is/was。主语是复数形式，be动词用are/were。There is a desk in the rm．There are tw chairs in the rm．There is n fd in the fridge. Let’s buy sme.
2. 两个名词作主语，there be句型采用就近原则。There are sme students and a teacher in the classrm. There is a teacher and sme students in the classrm. 3. 不定代词在句中作主语，谓语动词要用单数形式。There is nthing in the fridge.
there be句型否定句：be + ntThere aren't tw chairs and a desk in the rm．一般疑问句Is there anything wrng with yur ears？Yes, there is／N, there isn't.
反义疑问句（be there），要注意陈述部分的形式。There wasn't a meeting yesterday, was there?如果陈述部分含有little/few/n/nbdy/nne等否定词时，后面的简短问句中要用肯定形式。There is nbdy in the rm，is there？但有的含有否定意义的形容词修饰不定代词时则仍看作肯定句式。There is smething unusual in the rm，isn't there？
There be句型的时态。 be可以有现在时（there is/are） 过去时（there was/were，there used t be） 将来时（there is /are ging t be或there will be） 完成时（there have/has been）There was a knck at the dr.There used t be a church acrss frm the bank.There is ging t be a meeting tnight.
重要句式（有某人在做某事）There be＋主语＋ding sth＋地点／时间状语.There are several children swimming in the river．河里有几个孩子在游泳。
There be 句型表示猜测语气的用法可以在be前面加表示猜测语气的情态动词must，may，can，might等。There must be a pen in the bx.
there be句型和have\has的区别：桌子上有三本书. There are three bks n the desk.我有三本书. I have three bks.
there be句型表示 “存在有”， have\has表示 “拥有” “所有”， 两者不能同时使用。
