There be句型的用法

一、構(gòu)成：There be ...句型表示的是 “某處有(存在)某人或某物”，其結(jié)構(gòu)為There be(is，are，was, were )+名詞+地點(diǎn)狀語(yǔ)。例如：1) There is a pencil in my pencil-case.21*cnjy*com

二、各種句式：

否定句：在be后加上“not”,也可用“no”來(lái)表示。如：1) There is an orange in her bag.→There isn’t an orange in her bag. →There is no orange in her bag.

一般疑問(wèn)句：There be結(jié)構(gòu)的一般疑問(wèn)句變化只需把be動(dòng)詞移到句首，再在句尾加上問(wèn)號(hào)即可。例如：
4) There is some money in her handbag.
　→ Is there any money in her handbag? (疑問(wèn)句和否定句中，some改為any, something改為anything.)

5) There is something new in today’s newspaper.→Is there anything new in today’s newspaper?

特殊疑問(wèn)句：There be句型的特殊疑問(wèn)句有以下三種形式

① 對(duì)主語(yǔ)提問(wèn)：當(dāng)主語(yǔ)是人時(shí)，用 “Who’s + 介詞短語(yǔ)?”；當(dāng)主語(yǔ)是物時(shí)，用 “What’s + 介詞短語(yǔ)?”。其中there在口語(yǔ)中常常省略。注意：無(wú)論原句的主語(yǔ)是單數(shù)還是復(fù)數(shù)，對(duì)其提問(wèn)時(shí)一般都用be的單數(shù)形式(回答時(shí)卻要根據(jù)實(shí)際情況來(lái)決定)。如： 6) There is a bird in the tree. →What’s in the tree?
7) There are some bikes over there. →What’s over there?www-2-1-cnjy-com

8) There is a little girl in the room. →Who is in the room?

② 對(duì)地點(diǎn)狀語(yǔ)提問(wèn)：用 “Where is \ are + 主語(yǔ)?”表示（注意其答語(yǔ)變化）：例如：
9) There is a computer in my office. → Where is the computer? ----It’s in my office.
10) There are four children in the classroom. →Where are the four children?【來(lái)源：21cnj*y.co*m】

--They’ re in the classroom.
③ 對(duì)數(shù)量提問(wèn)：一般有兩種提問(wèn)方式：

如果主語(yǔ)是可數(shù)名詞，無(wú)論是單數(shù)還是復(fù)數(shù)，都用“How many +可數(shù)名詞復(fù)數(shù) + are there + 介詞短語(yǔ)？”表示：11) There are twelve months in a year. →How many months are there in a year?

12) There is only one book in my bag. → How many books are there in your bag?

13) There is a cat in the box. → How many cats are there in the box?21·世紀(jì)*教育網(wǎng)

如果主語(yǔ)是不可數(shù)名詞，則用“ How much + 不可數(shù)名詞 + is there + 介詞短語(yǔ)？”表示：

14) There is some money in my purse.→ How much money is there in your purse?

反意疑問(wèn)句：There be或There加其它動(dòng)詞，其反意疑問(wèn)句一律用…there? 例如：

15）There is a beautiful girl in the garden, isn’t there?2·1·c·n·j·y

三、用法：

1. There be句型中be動(dòng)詞的形式要和其后的主語(yǔ)在人稱(chēng)和數(shù)上保持一致。

1) There is a basketball in the box.　 There are many birds in the tree.　21·cn·jy·com

如果有兩個(gè)或兩個(gè)以上的名詞作主語(yǔ)，be動(dòng)詞要和最靠近它的那個(gè)主語(yǔ)在數(shù)上保持一致，也就是我們常說(shuō)的 “就近原則”。例如：5) There is an orange and some bananas in the basket.
6) There are some bananas and an orange in the basket.
2. There與be中間可插入一些表推測(cè)的情態(tài)動(dòng)詞、表時(shí)態(tài)的短語(yǔ)(如和將來(lái)時(shí)be going to\ will、現(xiàn)在完成時(shí) have\has + pp. ) 例如：1) There must be a pen in the box.

2) Is there going to be a dancing party tonight?4) There has been a big tree on the top of the hill.

3. 英語(yǔ)中有些動(dòng)詞或短語(yǔ)具有一定的情態(tài)含義，我們稱(chēng)之為半助動(dòng)詞。There be句型中的謂語(yǔ)動(dòng)詞be可與這些半助動(dòng)詞連用，表達(dá)更為復(fù)雜的意念。能用于There be句型中的這類(lèi)詞語(yǔ)主要有：happen to（碰巧），appear ／seem to（似乎），used to（曾經(jīng)），have to（必須），be likely to（很可能），be bound to（必定）等。例如：
1)There happened to be an old friend of mine in the club在那個(gè)俱樂(lè)部碰巧有我的一個(gè)老朋友。
2)There appear to be several reasons for changing our plans．看來(lái)改變我們的計(jì)劃有幾個(gè)理由。
3)There used to be a cinema here before the war．戰(zhàn)前這里曾有一個(gè)電影院。
4．There be +名詞+地點(diǎn)/時(shí)間狀語(yǔ)There was a party in the hall last night.

6．由there be構(gòu)成的固定句型
由there be構(gòu)成的一些固定句型在英語(yǔ)中很活躍，需很好地掌握。常見(jiàn)的有：
There is no point (in) v-ing：沒(méi)道理，沒(méi)用，沒(méi)必要
There is no use（in）＋v-ing：毫無(wú)用處 There is no sense (in) v-ing：毫無(wú)道理
There is no need （for sb.）to ＋v：沒(méi)有必要
There is no ＋v-ing：不可能，無(wú)法。 相當(dāng)于“It is impossible+ to do sth.”
例如： 1)There is no use in hiding that fact from him ．對(duì)他隱瞞那個(gè)事實(shí)沒(méi)什么用。
2) There is no point in arguing further．再爭(zhēng)下去也沒(méi)用。
3)Is there any point in going on？有必要再繼續(xù)下去嗎？
4)There was no need for him to remain in Shanghai．他沒(méi)有必要再留在上海。
5) There was no sense in making a child suffer likethat．讓一個(gè)孩子受那樣的苦是毫無(wú)道理的。
