There be 句型考点分析：There be 句型是考试的重点。重点：There be 句型的知识点。难点：让学生能够掌握There be 句型的知识点。考点一：There be 句型1、【定义】There be 句型用于表达“.地方有.”。即“某地有某物”。2、【结构】（1）There be句型的构成形式一般为“there is/are +某物/人 + 地点”。它既可以表示某地方有什么东西，也可以表示某地方有什么人。例子：There is an apple on the desk. 桌子上有一个苹果。 There are many students on the playground. 操场上有许多学生。 There is some water in the bottle. 在瓶子里有一些水。注意：观察以上两个句子，在there be 句型中，be是怎么变化的？当后面的物体是可数名词单数时，be要用_.当后面的物体是可数名词复数时，be要用_.当后面的物体是不可数名词时， be要用_.（2）There be 句型的肯定形式，否定形式，和一般疑问句形式。肯定否定一般疑问句回答There is a computer on the desk.There is not a computer on the desk.Is there a computer on the desk?Yes, there is.No, there isnt.There is some water in the bottle.There is not any water in the bottle.Is there any water in the bottle?Yes, there is.No, there isnt.注意：some和any的用法： 在肯定句中用some, 在疑问句和否定句中用any。（3）常见的There be 特殊疑问句及回答。How many/How much观察下列句子。-How many students are there on the playground?-There are four students on the playground.-How many buildings are there in your school?-There are six buildings in your school.-How many apples are there on the desk?-There is only one apple on the desk.由此可知，无论回答的事物是单数名词还是复数名词，其How many 的句型不变，即为：How many + _ + _ _ + 其它部分。How muchHow much用于对不可数名词的提问。例如：How much orange is there in your cup?How much water is there in the lake?3、【常考点】（1）就近原则。 就近原则指的是谓语动词根据离它最近的单词决定它的单复数。即“近水楼台先得月”。例如： 我们教室里有一块黑板和二十二张桌子。There is a blackboard and 22 desks in our classroom.试想一下，如果我们先说二十二张桌子，再说一块黑板，There be 句型中的be还会一样吗？应该是怎么样的句子呢？_（2）There be 句型后如果有行为动词，就用动词的ing形式。例如：There are some boys playing basketball over there.There are some students doing their homework.【课堂练习】（一）句型变换。1.
