4Be动词的用法教案1、b用Be动词的正确形式填空。1Jane and Tom my friends.2. My parents very busy every day. 3. She my best friend.1).只需在be（am, is, are，was, were）后面加上not 就行。但要注意缩写形式。如：I am not a student.You arent a teacher.He isnt a good man.I wasnt a student. You werent a student. (is not=isnt are not =arent was not= wasnt were not=werent )总结：am与not 一起时不缩写；is 与not 缩写为isnt ， are not 缩写为arent ,2).如： I am a student.-Are you a student? Yes, I am. He is reading books. -Is he reading books? No, he isnt. There is a new school in my hometown. - Is there a new school in your hometown(家乡)？Yes, there is.Practice:用be动词的正确形式填空。1. 5._yourbrotherintheclassroom? 6.Where_yourmother?She_athome. 7.How_yourfather? 8.MikeandLiuTao_atschool. 9.Whosedress_this? 10.Whosesocks_they? 11.That_myredskirt. 12.Who_I? 13.Thejeans_onthedesk. 14.Here_ascarfforyou. 15.Here_somesweatersforyou. 16.Theblackgloves_forSuYang. 17.Thispairofgloves_forYangLing.2、助动词be1）be + 动词不定式即be+to do，表示按计划安排将要做某事。如：The new shop is not to be opened until next Monday. Mary told me that she was to have class at that night. 2) be+going to do，表示打算或将要做某事。如：We are going to plant trees in the park.I didnt know if she was going to come here.be going to, will do, be to do都是用来表示将来时，区别如下：1. be going to 表将来 a)按计划，安排要发生的事eg. The book is going to be published next month. b)有迹象要发生的事eg. Look at the dark clouds, there is going to be a storm.2. will do 是表意愿eg. I will go back home tomorrow. 在说话时突然作出的决定时，一般用will的缩约式ll Im tired. I think Ill go to bed. 在有条件从句的主句中，一般不用 be going to, 而多用will, 如： If you meet difficulties, Ill stay with you and help you3.be to do表示客观安排或受人指示而做某事eg. We are to discuss the report next Saturday.I am to play football tomorrow afternoon. (客观安排，如这儿有场比赛定在明天下午，不去不行，不能由主观决定)Im going to play football tomorrow afternoon. (主观安排，如我只是和朋友约了明天下午踢足球以消遣时间，可去可不去，可由主观决定)3、There be句型there be句式为：there be+主语部分状语部分，表示某处存在某物，be常用现在时，过去时和将来时等。如：There is a park in Sanya.There were many books here last night. There will be a football match in your school next week.注意：There be句型中be动词的单复数形式由后面挨近的一项名词的单复数决定，这就是就近原则。如：There is a pen, two books and many pencils on the desk. 在本句中尽管有钢笔、书和铅笔，但是由于离be动词最近的一项是单数a pen，因此，be动词用单数is。There is a book and three cats there. There are three cats and a book there.针对数量提问的特殊疑问句的基本结构是：How many + 名词复数 + are there + 介词短语？How much + 不可数名词 + is there + 介词短语？Eg: How many books are there in your bag?How much water is there in the bottle?There be与have的区别用法不同：there be 表示某个时间或地方“存在”某人或某物，而have表示主语“拥有”某人或某物，作宾语的某人或某物属主语所有。注意：there be句型不能与have连用 如：不能说There have three students in the classroom.There be句型与have，has有时也可以通用。如：The classroom has ten desks. = There are ten desks in the classroom. 教室里有十张桌子。Practice:选择填空 ( )1.-Again, my computer doest work. - must be something wrong with the CPU A.There B.That C.It D.This ( )2.There some milk ,some eggs and a few apples on the table.
