1、-There be 句型用法归纳-第 3 页There be 句型用法归纳1. 定义:There be句型表示某处存在某物或某人。2. 结构: (1) There is /was+单数可数名词/不可数名词+ 地点状语. (2) There are/were +复数名词+地点状语. there是引导词,在句中不充当任何成分,翻译时也不必译出。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。 eg. There is a bird in the tree. 树上有一只鸟。 There is a teache
2、r 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。 3. There be句型与have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。 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。 (2)当ha
3、ve表示“包括”、“存在”的含义时,There be 句型与其可互换。 eg. A week has seven days. =There are seven days in a week. 一个星期有七天。 变脸一:否定句 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
4、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. 变脸二:一般疑问句 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,此为调整法。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)。看看下面两句是如何改头换面的吧: There is some water on Mars. Is there any water on Mars?
5、There are some fish in the water. Are there any fish in the water? 变脸三: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Whos+介词短语?;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 i
6、s in the room? 2)对地点状语提问:提问地点当然用Where is / are+主语?啦!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? 3)对数量提问:一般有两种句型结构: How many+复数名词+are /were there+介词短语? How much+不可数名词+is/was there+介词短语?4)反意疑问句:There be或There加其它动词,
7、其反意疑问句一律用there? 例如:There is a beautiful girl in the garden, isnt there?There used to be no school here, used there did there?注意事项:1. There be句型中be动词的形式要和其后的主语在人称和数上保持一致。如果句子的主语是单数的可数名词,或是不可数名词,be动词用“is”“was”。例如:There is a basketball in the box. There is a little milk in the glass.如果句子的主语是复数名词,be动词就用
8、“are” “were”。例如:There are many birds in the tree. There were many people in the street yesterday. 如果有两个或两个以上的名词作主语,be动词要和最靠近它的那个主语在数上保持一致,也就是我们常说的 “就近原则”。例如:There is an orange and some bananas in the basket. There are some bananas and an orange in the basket. 2. There与be中间可插入一些表推测的情态动词、表时态的短语和一些动词短语
