一、教学课题： There be 句型的使用二、教学目标：学生通过微视频的学习，能够正确地运用句型“There is ”“There are”来描述某处有某物。并能够在真实环境中熟练运用。三、教学重难点：能够在真实环境中熟练运用句型“There is ”“There are”来描述某处有某物。四、教学过程：Step One : 考点大观 1 There be 句型定义 There be 句型表示“某地存在某人/物”。它的构成形式:There areis某物人地点。即可以表示某地方有什么东西，也可以表达某地方有什么人。There is a cat under the tree.树底下有一只猫。There are two students in the classroom. 教室里有两个学生。 2 There be 句型的结构肯定句：there be + 其他There is a bag on the desk.否定句：there be + not + 其他There isnt a bag on the desk.疑问句：be + there + 其他Is there a bag on the desk?注意：询问的时候，be动词只能用单数is， 而回答时需视情况而选用单复数“Whats + 表示地点的介词短语”用there be句型来回答。Whats on the desk?There are 5 eggs on the desk.Step Two 易错辨析 1 There is +单数可数名词不可数名词There is a book on the desk .桌子上有一本书。There is some water in the bottle.瓶子里有些水。 2 There are +复数名词There are some pictures on the wall.墙上有些图画。There are two apples in the basket.篮子里有两个苹果。 3 There be 就近原则：若句子中有几个并列主语时，be动词的形式要与离其最近的一个主语在人称和数上保持一致。1.There is a girl and two boys under the tree.2.There are two boys and a girl under the tree. 4 There be与have的区别have/has与主语是 “所属关系”，强调的是 “拥有，占有” 。there be表示“存在关系”，强调某地“有”某物， （某地存在）I have many friends. 我有很多朋友。There is a book on the desk. 桌子上有一本书。Step Three 通关训练【典例1】What_ on the shelf?
