七年级英语There---be句型讲解和练习.doc

1、 There be句型 一、专题讲解 There be句型1、定义： There be 结构主要用以表达 “某地有某人(某物)”。其基本句型为“There be + 某物或某人(主语) + 某地”。 2、be动词的选择： There be 结构中的谓语动词be（is / are）在人称和数上应与其后的主语保持一致。主语是不可数名词或单数可数名词时用is ；主语是复数时用are。 3、具体结构：(1) There is + 单数可数名词/不可数名词+ 地点状语. E.g. There is a desk in the classroom. 在教室里有一张桌子。 (2) There are + 复

2、数名词+ 地点状语. E.g. There are 5 apples in the box. 盒子里有五个苹果。 口诀： “有”字放前面，有“啥”放中间； 时间地点放后面； 单数is, 复数are 注意be的两变化。 4、句型变化： (1)、否定句：there be的否定式通常在be后加not。 E.g. There is a bike under the tree. 树下有一辆自行车。 There isnt a bike under the tree. E.g. There are 2 little girls in the room.在房间里有两个小女孩。 There arent 2 li

3、ttle girls in the room. (2)、一般疑问句及其答语： 1、一般疑问句：把be动词提前,首字母大写,句末用问号即可。 2、回答时，“用什么问，就用什么答”，用Is / Are there来提问，就用there is / are来回答。 肯定回答：Yes, there is / are. 否定回答：No, there isnt / arent. E.g. 1、There are two cats in the tree.树上有两只猫。 Are there two cats in the tree? Yes, there are. No, there arent. . 2、T

6、ear here? - No, there are _ shops near here. A. some, not B. some, any C. any, not D. any, no 2There are some tables on the floor.（变为否定句） 6、就近原则： there是个近视眼。若句子中有几个并列的主语时, be的形式要与离其最近的一个主语在人称和数上保持一致。 E.g. 1.There is a pen, two pencils and some books on the desk. 书桌上有一支钢笔、两支铅笔和一些书。 2.There are two pe

8、同时合用。 E.g.1、I have a book .我有一本书。 （注：书归我所有，我是书的主人。 所属有） 2、There is a book on the desk .在桌子上有一本书。 （注：书只是存在于桌子上，但书不属于桌子所有。 存在有） 8、常见的的介词和介词短语： 介词：at 在. in 在.里面 on 在.上面 under 在.下面 behind 在.后面 near 在.附近 介词短语举例： at home 在家 in the box 在盒子 on the floor 在地板上 under the tree 在树下 behind the door 在门后面 near the
