1、初中there be 句型用法及配套练习一:there be 句型基本认识1、 定义:There be句型表示某处存在某物或某人。2、结构:(1) There is +单数可数名词/不可数名词+ 地点状语. (2) There are +复数名词+地点状语.注意事项: there是引导词,在句中不充当任何成分,翻译时也不必译出。句子的主语是某人或某物,谓语动词be要与主语(某人或某物)的数保持一致。当主语是两个或两个以上的名词时,谓语动词要与跟它最近的那个名词一致。如: There is a bird in the tree. 树上有一只鸟。 There is a teacher and ma
2、ny students in our classroom. 我们教室里有一位老师和许多学生。 There are two boys and a girl under the tree. 树下有两个男孩,一个女孩。二: there be 句型的常考点考点一:各种句型转化。1:变成否定There be句型的否定式的构成和含有be动词的其它句型一样,在be后加上not或no即可。注意not和no的不同:not是副词,no为形容词,not a/an/any + n. 相当于no+ n.。例如: There are some pictures on the wall. There arent any p
3、ictures on the wall. =There are no pictures on the wall. There is a bike behind the tree. There isnt a bike behind the tree. =There is no bike behind the tree.2:变成一般疑问句There be句型的一般疑问句变化是把be动词调整到句首,再在句尾加上问号即可。但同时要注意:当肯定句中有some时,要将其改为any(否定变化也一样)。There is some water on Mars. Is there any water on Mar
4、s? There are some fish in the water. Are there any fish in the water? 3:特殊疑问句对主语提问:当主语是人的时候,则用who 引导,当主语是物的时候,则用what 引导。注意:无论原句的主语是单数还是复数,对之提问时一般都用be的单数形式(回答时却要根据实际情况来决定)。如: There are many things over there. Whats over there? There is a little girl in the room.Who is in the room? 对地点状语提问:则用where 引导。
5、如:There is a computer on the desk. Where is the computer? There are four children on the playground. Where are the four children? 对数量提问:般有两种句型结构: How many+复数名词+are there+介词短语? How much+不可数名词+is there+介词短语?考点二:there be 句型的时态。be可以有现在时(there is/are)、过去时(there was/were)、将来时(there is/are going to be或ther
6、e will be)和完成时(there have/has been);还可用there must be ,there cant be, there used to be等。 如: -There _ a concert this evening.-Yeah. Exciting news! A. are going to be B. is going to be C. is going to have D. will have考点三:there be 句型反意疑问句的构成:be (not) there? 如:There is some milk in the bottle, _ ? Aisnt
7、there Barent there Cisnt it Dare there 考点四:there be 句型的主谓一致:There be 结构中的be动词要和后面所跟名词保持一致,遵循就近原则。如:1.There _ any rice in the bowl. A. are B. is C. isnt D. arent 2.There _ many apples on the tree last year. A. have been B. were C. are D. is 考点五:there be 句型用的其他动词:there be 句型中有时不用动词be ,而用come , live ,s
8、tand , lie, seem to be , happen to be ,等。如:There _ a knife and a fork on the table. (2007黄冈)A. seems to be B. seem to be C. is seeming to be D. are剖析:根据就近原则,首先排除B、D,而 there be 句型中有时不用动词be ,而用come , live ,stand , lie, seem to be等,所以答案应从A、C中选。感官动词一般不用进行时,故C也不正确。注意事项:there be 句型与have句型的区别(1) There be 句
9、型和have都表示“有”的含义。区别如下:There be表示“某处存在某物或某人”;have表示“某人拥有某物/某人”,它表示所有、拥有关系。如: He has two sons. 他有两个儿子。There are two men in the office. 办公室里有两个男人。(2)当have表示“包括”、“存在”的含义时,There be 句型与其可互换。如: A week has seven days. =There are seven days in a week. 一个星期有七天。三:课堂实地演练I. 将下列句子变成否定句和一般疑问句。1.There is some water
10、in the bottle.2.There are many apples in the box.II. 对句子划线部分提问。3.There are seven days in a week. 4.There are lots of books in our library.5.There is a knife over there.6.There is a little milk in the glass. 单项填空。( )8.There_ not _ milk in the cup on the table .A. are, many B. are , much C. is ,many D
