E.g. There is a desk in the classroom. 在教室里有一张桌子。 (2) There are + 复数名词+ 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。 考点/易错点4：4、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 little 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、There is a computer on the desk . 在桌子上有一台电脑。 Is there a computer on the desk？ Yes, there is. No, there isnt.考点/易错点5：5、some和any在“there be”句型中的用法： some 一些（some用于肯定句） any 一些（any用于否定句和一般疑问句） 注意：There be句型在变成否定句或一般疑问句时，要注意把句中的some变成any。 E.g.1、There is some water in the bottle .在瓶子里有一些水。 There isnt any water in the bottle.（否定句） Is there any water in the bottle？（一般疑问句） 2、There are some children in the picture. 图片里有一些小孩。 There arent any children in the picture. （否定句） Are there any children in the picture？（一般疑问句）考点/易错点6：6、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 pencils, a pen and some books on the desk. 书桌上有两支铅笔、一支钢笔和一些书。3.There some books，two pencils and a pen on the desk. 书桌上有一些书、两支铅笔和一支钢笔。 考点/易错点7：7、“there be” 和“have”的区别 There be表示“存在有” ；have（has）表示“所属有”。他们都翻译为“有”，但具体用法不相同，且两种结构不能同时合用。 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）三、例题精析【例题1】【题干】1.
