(2) There are +复数名词+地点状语.,There be + sth + 地点状语（介词短语） There is a flower in the bottle. 瓶里有朵花。 There is some money in the purse. 包里有些钱。【不可数名词be动词用is】 There are some books on the desk.桌上有些书。【可数名词be动词用are 】 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。 【就近原则】 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 under the tree. 树下有两个男孩，一个女孩。,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 pictures 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 Mars? 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。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：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？ 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there will be)和完成时(there have/has been)；还可用there must be ,there cant be, there used to be等。,练习,变成疑问句并作否定回答，和否定句。 There is a cup on the table. 疑问句： 否定回答： 否定句： 用a，an，the填空 Give me _book . Which book? _book on the desk.,对句子划线
