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.
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。
eg. ① There is a bird in the tree. 树上有一只鸟。
② 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。
③ There are two boys and a girl under the tree. 树下有两个男孩,一个女孩。
3. There be句型与have的区别:
(1) There be 句型和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。 eg.
①He has two sons. 他有两个儿子。
②There 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。
eg. A week has seven days. =There are seven days in a week. 一个星期有七天。
变脸一:否定句
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 aren't any pictures on the wall. =There are no pictures on the wall.
There is a bike behind the tree. → There isn't a bike behind the tree. =There is no bike behind the tree.
变脸二:一般疑问句
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,此为\"调整法\"。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)。看看下面两句是如何\"改头换面\"的吧:
There is some water on Mars. → Is there any water on Mars?
There are some fish in the water. →Are there any fish in the water?
变脸三:特殊疑问句
There be句型的特殊疑问句形式有以下三种变化:
① 对主语提问:当主语是人时,用\"Who\'s+介词短语?\";当主语是物时,用\"What\'s + 介词短语?\"。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. →What's over there?
There is a little girl in the room.→Who is in the room?
② 对地点状语提问:提问地点当然用"Where is / are+主语?\"啦!例如:
There is a computer on the desk. → Where is the computer?
There are four children on the playground. →Where are the four children?
③ 对数量提问:一般有两种句型结构:
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?
