(2) There are +复数名词+地点状语.本卷须知: 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

9、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。w W w . There is a teacher and many 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1:变成否认There be句型的否认式的构成和含有be动词的其它句型一样,在be后加上not即可。例

10、如: 例1: There are some pictures on the wall. =There arent any pictures on the wall. 例2:There is a bike behind the tree. = There isnt a 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否认变化也一样。some 用于肯定句, any用于否认或疑问句。There is some water on Mars.

Whats over there There is a little girl in the room.Who is in the room 对地点

12、状语提问:那么用where 引导。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?
