大家好,我是there be句型, 我的中文名字是“有”,表示某处存 在某(物)人。基本结构为"There be +某物(某人)+某地(某时)”。我常见的结构有两种:
1 There is +单数名词(不可数名词) +介词短语
eg. There is a girl in the house.
2 There are +复数名词 +介词短语
eg. There are four desks in the room. There 是个近视眼
就近原则：be动词的单复数要跟there be 句型的第一个主语保持一致，如果第一个主语是单数或者是不可数名词用is,如果第一个主语是附属用are。Check
1.There ____ a student in the classroom.
2.There ____ three books on the desk.
3.There ____ a student and three desks in the classroom.isareisThere be 句型的一般过去式
there be句型的一般过去式表示过去去过某地或某时存在某人或某物，其一般过去时态的陈述句由'' there +was/were+主语+时间/地点状语 ''构成。1.there was后接单数名词
eg. There was a car under the tree a moment ago.
2.there were后接复数名词。
eg. There were two foreign teachers last year.Check
