语法There be句型（课件）通用版通用版英语六年级下册

There be句型 Dacy老师 There be 句型的用法 表示某个地方存在某物或某人,Be动词的单复数必须依主语的变化而变化。(单数is 复数are ) eg:There is a table in the room. 房间里有一张桌子。 There are some birds on the tree.树上有很多鸟。 一、 There be 句型的结构 1.常见句型结构 (一)There is+单数可数+地点状语 eg:There is a ruler on the desk. 书桌上有一把尺。 (二)There are+复数主语+地点状语 eg:There are four apples on the tree. 树上有四个苹果。 There are some flowers in the park. 公园里有许多花。 (三)there is + 不可数名词 +地点状语 (即使有some 也是 单数) eg:There is some water in the bottle. 瓶子里有一些水。 (水是不可数名词) 2. There be选择就近原则: There be句型的就近原则是There be句型中语法项目的重点考点。There be句型中be动词的单复数形式由最挨近的一项的单复数决定。 如:There is a pen, two books and many pencils on the desk. (在本句中尽管有钢笔、书和铅笔,但是由于离be动词最近的一项是单数a pen,因此,be动词用单数is。) 二、There be 句型的疑问句及回答 (一)There be 句型的疑问 1. 在“There is/are...”的疑问句中,要把Be动词放在there之前,并将句号变问号。难点:句中出现的some要改成any。 2. 肯定回答为:Yes, there is/are. 3. 否定回答为: No, there isn’t/aren’t. eg: 可数名词单数1. 肯定句There is an apple on the tree. 疑问句 Is there an apple on the tree? 肯定回答: Yes, there is. 否定回答: No, there isn’t. 可数名词复数2. 肯定句There are five pens on the desk. 疑问句Are there five pens on the desk? 肯定回答: Yes, there are. 否定回答 No, there aren’t. 不可数名词的时候 3.肯定句 There is some water in the cup.

(二)There be 句型的特殊疑问句: There be句型的特殊疑问句形式有以下三种变化: ① 对主语提问:当主语是人时,用\"Who\'s+介词短语?\"; 当主语是物时,用\"What\'s + 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)。) ② 对地点状语提问:提问地点用"Where is / are+主语?\“ ③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? eg:How many people are there in the picture? How much water is there in the bottle ? 三、There be 句型的否定形式 There be 句型的否定: 否定形式只要在be动词后面加not即可,is not =isn’t are not= aren’t 但要注意的是句中如果出现some则改成any. 1.There is a knife in the kitchen. ——否定:There is not a knife in the kitchen. 2.There are five apples on the tree. —— 否定:There are not five apples on the tree. 3.There is some water in the bottle. ——否定:There is not any water in the bottle. 4.There are some birds singing in the tree. ——否定:Th
