Answer the following questions How many desks are there in the classroom. How many chairs are there in the classroom. How many doors are there in the classroom. How many maps are there in the classroom. How many blackboards are there in the classroom. Grammar: there be是一个常用的固定结构，“某地有某物”的意思，表示“存在有”。there be不可表示“所有或拥有”，表示这个意思必须用have,第三人称用has.在一般现在时态中，there be的单数形式是there is,复数形式是there are. There be 句型的用法: 如，There is a big ground and some tall trees in front of our classroom.我们教室前有一个大运动场和一些高树。注意：be动词用单数还是复数要依据‘就近原则’。如上面例句也可改成There are some tall trees and a big ground in front of our classroom. 否定句是在be后加not；一般疑问句是将be放在句首。 例如： There is a desk and two chairs in the room．（紧挨着be动词的主语是a desk，是单数，故be的形式要用is） There aren‘t two chairs and a desk in the room．（否定句） Is there a gym next to the dining room？（Yes，there is．／No，there isnt．） Exercises1:根据中文完成句子 1. 桌子上有一本书和两支钢笔.There __a book a
