There be 句型
There be ...句型表示的是“某处有(存在) 某人或某物”。1. 肯定句结构：There be (is，are)+名词+地点状语e.g. 在我的铅笔盒里有两块橡皮。 _____ ___ tw erasers in my pencil bx. 在房子前有一棵大树。_____ __ a tall tree in frnt f the huse.2. 否定句结构：There isn’t / aren’t…e.g. 大桥街上没有银行。______ _____ a bank n Bridge Street.教室里没有篮球。 ______ ______ any basketballs in the classrm.

Is there

(公共汽车是属于我们工厂所有的)2.当表示某物的构成和组成部分时, 用there be 和have均可。例如： Our schl has twenty classes. (= There are twenty classes in ur schl.)
