There be句型的用法

一、構成：There be ...句型表示的是 “某處有(存在)某人或某物”，其結構為There be(is，are，was, were )+名詞+地點狀語。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.

一般疑問句：There be結構的一般疑問句變化只需把be動詞移到句首，再在句尾加上問號即可。例如：
4) There is some money in her handbag.
　→ Is there any money in her handbag? (疑問句和否定句中，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?

特殊疑問句：There be句型的特殊疑問句有以下三種形式

① 對主語提問：當主語是人時，用 “Who’s + 介詞短語?”；當主語是物時，用 “What’s + 介詞短語?”。其中there在口語中常常省略。注意：無論原句的主語是單數還是復數，對其提問時一般都用be的單數形式(回答時卻要根據實際情況來決定)。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 對地點狀語提問：用 “Where is \ are + 主語?”表示（注意其答語變化）：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?【來源：21cnj*y.co*m】

--They’ re in the classroom.
③ 對數量提問：一般有兩種提問方式：

如果主語是可數名詞，無論是單數還是復數，都用“How many +可數名詞復數 + are there + 介詞短語？”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*教育網

如果主語是不可數名詞，則用“ How much + 不可數名詞 + is there + 介詞短語？”表示：

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

反意疑問句：There be或There加其它動詞，其反意疑問句一律用…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動詞的形式要和其后的主語在人稱和數上保持一致。

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

如果有兩個或兩個以上的名詞作主語，be動詞要和最靠近它的那個主語在數上保持一致，也就是我們常說的 “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的情態(tài)動詞、表時態(tài)的短語(如和將來時be going to\ will、現在完成時 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. 英語中有些動詞或短語具有一定的情態(tài)含義，我們稱之為半助動詞。There be句型中的謂語動詞be可與這些半助動詞連用，表達更為復雜的意念。能用于There be句型中的這類詞語主要有：happen to（碰巧），appear ／seem to（似乎），used to（曾經），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在那個俱樂部碰巧有我的一個老朋友。
2)There appear to be several reasons for changing our plans．看來改變我們的計劃有幾個理由。
3)There used to be a cinema here before the war．戰(zhàn)前這里曾有一個電影院。
4．There be +名詞+地點/時間狀語There was a party in the hall last night.

6．由there be構成的固定句型
由there be構成的一些固定句型在英語中很活躍，需很好地掌握。常見的有：
There is no point (in) v-ing：沒道理，沒用，沒必要
There is no use（in）＋v-ing：毫無用處 There is no sense (in) v-ing：毫無道理
There is no need （for sb.）to ＋v：沒有必要
There is no ＋v-ing：不可能，無法。 相當于“It is impossible+ to do sth.”
例如： 1)There is no use in hiding that fact from him ．對他隱瞞那個事實沒什么用。
2) There is no point in arguing further．再爭下去也沒用。
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．他沒有必要再留在上海。
5) There was no sense in making a child suffer likethat．讓一個孩子受那樣的苦是毫無道理的。
