There be 句型1) 定义：There be句型表示某处存在某物或某人。2) 结构： There is+第三人称单数可数/不可数名词+地点状语例：There is a ruler on the desk. 书桌上有一把尺。There is some water in the bottle. 瓶子里有一些水。 There are+复数名词+地点状语例：There are four apples on the tree.树上有四个苹果
4、。There are many flowers in the park.公园里有许多花。 there是引导词，在句中不充当任何成分，翻译时也不必译出。注意：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。21cnjycom There is a bird in the tree. 树上有一只鸟。 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 und
5、er the tree. 树下有两个男孩，一个女孩。www.21-cn-3) There be 句型转换变脸一：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.。There be否定句型中的not any与no可以互换。not any强调一个都没有。21cnjy1.

7、the tree. There isnt 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
8、 in the water? 肯定回答为：Yes, there is/are. 否定回答为: No, there isnt/arent.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： 对主语提问：当主语是人时，用 “Whos+介词短语?”；当主语是物时，用 “Whats + 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：21教育网来源:学。科。网There are many things over there.
