2019七年级英语语法复习 Be动词的用法总结及专项练习(无答案) (新版)外研版 (7)

There be句型的用法一、构成：There be ...句型表示的是“某处有(存在)某人或某物”，其结构为There be(is，are，was, were )+名词+地点状语。

例如：There are fifty-two students in our class.There is a pencil in my pencil-case.There was an old house by the river five years ago.二、各种句式：否定句：There be句型否定句式的构成和含有be动词的其它句型一样，在be后加上“not”。

也可用“no”来表示。

即：no + n.（名词）= not a\an\any + n.（名词）。

注意：no + n.（可数名词单数）= not a\an + n.（可数名词单数）；no + n.（可数名词复数）= not any + n.（可数名词复数）；no + n.（不可数名词）= not any + n.（不可数名词）。

例如：There is an orange in her bag.→There isn’t an orange in her ba g.→There is no orange in her bag.There are some oranges in her bag.→There aren’t any oranges in her bag.→There are no oranges in her bag.There is some juice in the bottle.→There isn’t any juice in the bottle.→There is no juice in the bottle.一般疑问句：There be结构的一般疑问句变化只需把be动词移到句首，再在句尾加上问号即可。

例如：There is some money in her handbag.→ Is there any money in her handbag? (疑问句和否定句中，some改为any, somet hing改为anythin g.)There is something new in today’s newspaper.→There isn’t anything new in today’s newspaper.→Is there anything new in today’s newspaper?特殊疑问句：There be句型的特殊疑问句有以下三种形式：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?”。

其中there在口语中常常省略。

注意：无论原句的主语是单数还是复数，对其提问时一般都用be的单数形式(回答时却要根据实际情况来决定)。

如：There is a bird in the tree. →What’s in the tree?There are some bikes over there. →What’s over there?There is a lit tle girl in the room. →Who is in the room?②对地点状语提问：用“Where is \ are + 主语?”表示（注意其答语变化）：例如：There is a computer in my office.→ Where is the computer? ----It’s in my office.There are four children in the classroom.→Where are the four children?—They’ re in the classroom.③对数量提问：一般有两种提问方式：如果主语是可数名词，无论是单数还是复数，都用“How many +可数名词复数 + are there + 介词短语？”表示：There are twelve months in a year.→How many months are there in a year?There is only one book in my bag.→ How many books are there in your bag?There is a cat in the box.→ How many cats are there in the box?如果主语是不可数名词，则用“ How much + 不可数名词 + is there + 介词短语？”表示：There is some money in my purse. How much money is there inyour purse?反意疑问句：There be或There加其它动词，其反意疑问句一律用…there? 例如：There is a beautiful girl in the garden, isn’t there?There used to be no school here, used there \did there?三、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 b asketball 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“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 (如和将来时be going to\ will、现在完成时 have\has + pp. 、used to结构等连用，注意其构成形式,这一内容在我们日常练习中经常出现错误,是一难点,也是历年中考试题中的一个考点.)。

例如：There must be a pen in the box.There happened to be s ome money in my pocket.There is going to be a meeting tonight.There has been a big tree on the top of the hill.There used to be a church across from the bank.3. There be句型和have\has的区别：Th ere be句型表示“存在有”, have\has表示“拥有” “所有”,两者不能同时使用.例如：桌子上有三本书. There are three books on the desk.我有三本书. I have three books.4. There be + 主语 + doing +介词短语. 例如：There is a truck collecting rubish outside.There is a wallet lying on the ground.四、练习：Choose the best answers.1. There isn’t _____water in the glass.
