There be 句型是英语中最为常用的句型之一, 主要用来表示“人或事物的存在”或“某地有某物”。
There在此结构中是引导词,已经没有副词“那里”的含义。be后的名词是句子的主语。其基本用法结构为:
There be+名词主语(人或物)+地点
其中,be的形式随着后面的名词时单数还是复数而变化,即:当be后面接的是单数可数名词,则采用is;当be后面接的是复数可数名词,则采用are。如:
There is a man under the tree.
There are some apples on the table.
【注意】1、否定句There be的否定句一般是直接在be后加not,not可以缩略为't。如果原句中还有some,一般要改为any。如:
There isn't a man under the tree.
There aren't any apples on the table.
还有一种否定表达方式是通过no来表达,此时的no相当于not...any。如:
There is no water in the bottle.
There isn't any water in the bottle.
There are no pictures on the wall.
There aren't any pictures on the wall.
2、一般疑问句There be句型要改为一般疑问句,只要把be提到句首即可。其肯定回答为:Yes, there is/are,否定回答为:No, there isn't/aren't。如果原句中含有some,也要改为any。如:
- Is there a man under the tree?
- Yes, there is. / No, there isn't.
- Are there any apples on the table?
- Yes, there are. / No, there aren't.
3、特殊疑问句There be 句型的特殊疑问句主要有how many和how much做引导词两种情况。如:
There are five thousand students in our school. (就five thousand提问)
How many students are there in your school?
There is a little money in my wallet. (就a little提问)
How much money is there in your wallet?
4、反义疑问句There be的反义疑问句一般是以be作为反义疑问部分的助动词来用,它也遵循“前肯后否、前否后肯”的原则。如:
There is a cup on the table, isn't there?
该句前半句为肯定句,所以反义疑问句部分要采用否定的isn't。
There is no juice left in the bottle, is there?
该句前半句为否定句,所以反义疑问句部分要采用肯定的is。
二、主谓一致1、不可数名词作主语
当be后接的是不可数名词时,be要采用is;当其后接的是由表量的名词的复数所连接的不可数名词时,be要采用are。如:
There is some bread on the plate.
There are three pieces of bread on the plate.
2、就近原则
如果There be 后面是几个并列名词时,动词be的形式和最靠近它的那个名词保持数的一致。如:
There is an apple, two plates and five bowls on the table.
There are two plates, an apple and five bowls on the table.
三、时态变化There be 句型中的be可以有一般现在时、一般过去时、将来时和完成时的变化。如:
There are some people talking loudly in the reading room.
There was a car race in the town last year.
There will be a meeting next Friday.
There has been a great increase in population in the city in the past five years.
There be句型也可以与情态动词连用。其基本用法结构为:There+情态动词+be+名词主语+其他成分。如:
There may be a great exhibition in Shanghai next year.
There must be some cakes left in the box.
There used to be a hospital there before the war.
There be句型也可以和be going to 、seem to 、appear to 、used to、be likely to 、happen to等常用句型连用。其基本用法结构为:There+特殊句型+be+名词主语+其他成分。如:
There seem to be a big difference between the twins.
There is going to be a film in the village tonight.
There is likely to be a snowstorm.
There happened to be a man nearby.
There appeared to have been a tragic accident last week.
There be句型中的be有时会被替换为其他行为动词。如:
There came a breeze that his wife had eloped with her lover. (有谣言说他妻子与她情人私奔了。)
Once upon a time, there lived a princess who was very beautiful. (从前,有一位非常美丽的公主。)
There be和have都可以表示“有”的意思,此时两者的用法可以相互转化。如:
There are many small rivers in the ancient town.
The ancient town has many small rivers.
但是,只有There be能够用来表存在,侧重表达某地有某物,而have没有此用法。如:
There are some trees in front of the house.
这句话中的There are就无法转化为have的用法。
There be 结构的非谓语动词形式是there to be 和there being 两种形式。在句中作主语、宾语和状语。
1、作主语
There being a bus stop near my house is a great advantage. (我家旁边有个公共汽车站,很是方便。)
2. 作宾语
there to be可以用作expect、like、mean、intend、want、prefer等动词的复合宾语。如:
I expect there to be no argument about this. (我期望关于这件事不要再争吵了。)
People don't want there to be another war. (人们不希望再有战争了。)
有时也会用作介词的宾语,其形式一般为there being。如:
I never dreamed of there being any good chance for me. (我做梦也没想到我会有好机会。)
3、作状语
作状语时,通常采用“there being”结构。如:
There being no one to help me, I had to do it all alone. (因为没有人帮助我,我不得不独立完成这项工作。)
