There be句型知识归纳
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.
下面这首歌诀可帮你巧记there be句型结构:
There be放句首,主语跟在后。地、时放句末,强调置前头。如:
There is a book on the desk.
有时为了强调地点,也可把介词短语放在句首。如:
On the desk there is a book.
二、各种句式:
1.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 bag.
→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.
2.一般疑问句: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, something改为anything.)
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?
3.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 little 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:
a.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?
b.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 in your purse?
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。
a.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.
b.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.
c.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 be句型和have\has的区别:
There 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:
a.桌子上有三本书. There are three books on the desk.
b.我有三本书. I have three books. |
