4Be動(dòng)詞的用法教案1、b用Be動(dòng)詞的正確形式填空。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。但要注意縮寫(xiě)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 )總結(jié)：am與not 一起時(shí)不縮寫(xiě)；is 與not 縮寫(xiě)為isnt ， are not 縮寫(xiě)為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(家鄉(xiāng))？Yes, there is.Practice:用be動(dòng)詞的正確形式填空。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、助動(dòng)詞be1）be + 動(dòng)詞不定式即be+to do，表示按計(jì)劃安排將要做某事。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?qū)⒁瞿呈隆Ｈ纾篧e 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都是用來(lái)表示將來(lái)時(shí)，區(qū)別如下：1. be going to 表將來(lái) a)按計(jì)劃，安排要發(fā)生的事eg. The book is going to be published next month. b)有跡象要發(fā)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. 在說(shuō)話時(shí)突然作出的決定時(shí)，一般用will的縮約式ll Im tired. I think Ill go to bed. 在有條件從句的主句中，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表示客觀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. (客觀安排，如這兒有場(chǎng)比賽定在明天下午，不去不行，不能由主觀決定)Im going to play football tomorrow afternoon. (主觀安排，如我只是和朋友約了明天下午踢足球以消遣時(shí)間，可去可不去，可由主觀決定)3、There be句型there be句式為：there be+主語(yǔ)部分狀語(yǔ)部分，表示某處存在某物，be常用現(xiàn)在時(shí)，過(guò)去時(shí)和將來(lái)時(shí)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動(dòng)詞的單復(fù)數(shù)形式由后面挨近的一項(xiàng)名詞的單復(fù)數(shù)決定，這就是就近原則。如：There is a pen, two books and many pencils on the desk. 在本句中盡管有鋼筆、書(shū)和鉛筆，但是由于離be動(dòng)詞最近的一項(xiàng)是單數(shù)a pen，因此，be動(dòng)詞用單數(shù)is。There is a book and three cats there. There are three cats and a book there.針對(duì)數(shù)量提問(wèn)的特殊疑問(wèn)句的基本結(jié)構(gòu)是：How many + 名詞復(fù)數(shù) + are there + 介詞短語(yǔ)？How much + 不可數(shù)名詞 + is there + 介詞短語(yǔ)？Eg: How many books are there in your bag?How much water is there in the bottle?There be與have的區(qū)別用法不同：there be 表示某個(gè)時(shí)間或地方“存在”某人或某物，而have表示主語(yǔ)“擁有”某人或某物，作賓語(yǔ)的某人或某物屬主語(yǔ)所有。注意：there be句型不能與have連用 如：不能說(shuō)There have three students in the classroom.There be句型與have，has有時(shí)也可以通用。如：The classroom has ten desks. = There are ten desks in the classroom. 教室里有十張桌子。Practice:選擇填空 ( )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.
