There be 句型 知识点和练习

There be 句型1.There be句型表示“某处有某物”（1）其中there is 用于单数名词或不可数名词，如： There is a pencil case in the school bag. There is some soup/milk /tea/coffee/juice/water/chocolate.（2）There are用于可数名词的复数，如： There are some desks in the classroom. （3）There be 句型的就近原则：be动词后面如果跟的是不止一种物品，就根据离它最近的物品选用is或are.如：There _ some pictures and a telephone. There _a telephone and some pictures. 2.There be 句型的否定形式：在be动词的后面加not（is not可以缩写为isnt，are not可以缩写为 arent）注意：有some 的要改成any。 例：There is a pencil in the pencil-box.（改为否定句） There _ a pencil in the pencil-box. There are some crayons on the desk.（改为否定句） There _ _crayons on the desk. “some”和“any”都有“一些”的意思.“some”一般用于肯定句，“any”用于否定句和一般疑问句。但在一些表示委婉请求，想得到对方肯定回答的疑问句中，也用“some”. 例：1.There are some watermelons in the basket.(肯定句) 2.There arent any birds in the tree.(否定句) 3.Are there any toy trains on the table?(疑问句)4.Would you like some tea?(表委婉请求)3.There be句型的疑问句（1）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?（2）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： 1. 当主语是人时：用“whos +介词短语”2. 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，对之提问时一般用be动词的单数形式is。（回答时却要根据实际情况来决定）1. There are many books over there. over there?2. There is a little girl in the room. in the room? 对地点状语提问：提问地点用Where is / are+主语? 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? 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?句型转换：
