期末重难点牛津深圳版七年级英语上册.docxVIP

深圳版牛津版七年级上?期末重难点 1、 There be句型： 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：?? 1）There are some pictures on the wall. ? ?→There arent any pictures on the wall. ??? =There are no pictures on the wall.? ?2）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 can’t be, there used to be等。如：---There ______ a concert this evening. ---Yeah. Exciting news!??? A. are going to be?? ?B. is going to be??? C. is going to have??? D. will have ?key: B ? 三、there be 句型反意疑问句的构成：be (not) there??如： There is some milk in the bottle, ____ ? ??A．isnt there?? B．arent there?? C．isnt it??D．are there key: A? 四、there be 句型的主谓一致： There be 结构中的be动词要和后面所跟名词保持一致,遵循就近原则。如： 1.There ___ any rice in the bowl. ? A. are????B. is??? C. isn’t???D. aren’t?2.There ___ many apples on the tree last year.?? A. Have been??? B. were???? C. are???D. is key: B; B?? ? 五、注意事项：there be 句型与have句型的区别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。?如：He has two sons.?? 他有两个儿子。 There are two men in the office.??? 办公室里有两个男人。
