therebe句型解析（3篇）
1.therebe句型解析 篇一
1、当动词be后所接的名词是单数可数名词或不可数名词时，be 应该取单数is;当其后所接的名词是复数的.可数名词时，be用复数are。
There is some apple juice in the bottle.
瓶子里有些苹果汁。
There are some strangers in the street.
大街上有一些陌生人。
2、There be 句型中动词be可以有一般现在时、一般过去时、将来时和完成时。

3、There be 句型可以和各种助动词、情态动词连用。

there be句型和have区别：
1、相同点：在表示结构上的含有时，既可以用there be 句型，也可以用have来表示。
How many days are there in March?/How many days does March have?
三月份有多少天?
2、区别点：there be 意为存在，强调某地有某物，不表示所属关系;have 表示所有关系，强调某人或某地有某物，这是其基本用法。
There are some trees in front of the house.
房前有些树。
there be句型其他用法：
1、there be 结构作宾语时，通常用there to be ，常作这样一些词的宾语：expect，like， mean，intend，want，prefer，hate等。
I expect there to be no argument about this.
我期望关于这件事不要再争吵了。
2、there be作介词宾语时，如果是介词for，只能用“there to be”其它介词用“there being”。
I never dreamed of there being any good chance for me.
我做梦也没想到我会有好机会。
2.therebe句型解析 篇二
一、基本结构
There be+名词+方位介词短语。含义:某地有某物。其中There be是“有”的意思。如:
There is a book on the desk.
“有”“某物”“某地”
有时为了强调“某物”的位置, 可以把“某地”放在句子开头。例如,
Under the tree there are many flowers.“under the tree (某地) ”放在句首, 起强调作用。
二、与have/has (有) 的区别
There be句型是:某地“有”某物。只知道“某物”存在于“某地”, 不强调或者不交代“某物”的主人。该句型重在表达“存在”, 故被称之为“存在的有”。如There are some boxes in the room.此句中只说明“boxes”“in the room”, 而不知道“boxes”的“主人” (拥有者) 。
而have一般表示“所有、拥有”, 知道东西的主人。该句型通常是:sb have (has) sth, 某人拥有某物。
三、与there be相关的题型及解题对策
1. 变为一般疑问句
方法:直接将be动词移到句首。 (some要改成any, 人称、大小写作相应的变化。)
如:There is some juice in my bottle.
→Is there any juice in your bottle? (应该将some<常用于肯定句>改成any<常用于否定句和疑问句>。my改成your<人称变化规律:一、二交换三不变>) 。
2. 变为否定句
方法:直接在be动词后面加上not。
如:There are some bags near the chair.
→There aren’t any bags near the chair.
或:There are no bags near the chair.
3. 对划线部分提问
(1) 对句中的名词提问
方法:What’s+方位介词短语?
如:There are three apples on the tree.
→What’s on the tree?
(2) 对句中的方位介词短语 (表示地点) 提问
方法:Where+一般疑问句?
如:There are twelve pears in the box.
→Where are there twelve pears?
(3) 对句中可数名词的数量提问
方法:how many+可数名词的复数+一般疑问句?
如:There are three apples on the table.
→How many apples are there on the table?
(4) 对句中不可数名词的数量提问
方法:How much+不可数名词+一般疑问句?
如:There is a bottle of milk in the box.
→How much milk is there in the box?
4. 变为反意疑问句
方法:在该句末尾加上一个简短问句 (简短问句即该句变为一般疑问句的前两个单词。须注意的是, 若主句为肯定, 则简短问句为否定;若主句为否定, 则简短问句用肯定。)
如:There is much water on the floor, ?
→There is much water on the floor, isn’t there?
5. 单、复数变化
方法:is与are交换, a/an与some交换, 名词单数与复数交换。
如:There are some oranges in the basket. (改为单数形式)
→There isanorange in the basket. (be和名词作相应的变化)
6. 和have进行同意句转换
如:There are five pencils in Tom’s hand.
→Tom has five pencils in his hand.
7. 用动词的适当形式填空
There_______ (be) a pen and eleven ball-pens in the pencil-box.
答案:is。虽然共计有12支笔, 但是距离be动词最近的名词a pen是单数, 所以仍然要使用is而不使用are。这就是英语中的“就近原则”。
8. 选择
There________a film (电影) in our school tomorrow.
A isB have
C will beD will have
答案:C。分析:因为tomorrow表示将来发生, 所以选项A、B均不符合要求。该句是一个there be句型, 故不能选用have, 所以只能选C。
牛刀小试:
1.—What did you see on the desk then?
—There________ a bottle of orange.
A.was B.were
C.has D.had
2.There____ an English film here tomorrow.
A.has
B.is going to be
C.will have
3.Thereto few
(选择错误的一项)
4.—What’s on the plate?
—There_________ some bread on it.
A.is B.are
C.has D.have
5.There__________ a clock on the wall.
A.is B.are
C.have D.has
6.—__________there a radio on your desk?
—Yes, ___________.
A.Is, it, is B.Are, they are
C.Is, there is D.Is, there isn’t
7.There _________a pencil, a book and two pens on the table.
A.is B.are
C.am D.have
8.—______there_________ shops near here?
—No, there are __________shops near here.
A.Is, some, not
B.Are, some, any
C.Is, a, no any
D.Are, any, no
3.Units9－10重点句型解析 篇三
1. should表推测的用法
【课文原句】I should be home in about ten minutes.
【经典考例】
—When can I come for the phones? I need them tomorrow afternoon.
—They_______be ready by 12:00.
(NMET 1998)
A. can B. should C. mightD. need
【考点解析】答案为B。should表推测，指有一定主观根据的判断，意为“估计；按理应当”；can表推测常用于否定句或疑问句中，表示“有时会；可能”；might表示没有把握的推测，语气较弱；need表“必须；需要”，不符合句意。
2. no matter ＋疑问词引导的状语从句
【课文原句】The answer seems to be that we have a need to stay in touch with friends and family no matter where we are or what we are doing.
【经典考例】He tried his best to solve the problem, _______difficult it was. (2005重庆)
A. howeverB. no matter
C. whatever D. although
【考点解析】no matter这个词组的意思是“不管”，“无论”，常用what，who，when，where等疑问词连用，引导一个表示让步的状语从句，分别表示“不管何事、何人、何时、何地”等意思，可以和“疑问词＋ever”相互换用。答案为A。 B项应在no matter后加how才对。
3. in case的用法
【课文原句】Having a cellphone also makes us feel safer, since we can call for help in case of an emergency.
【经典考例】
1. John may phone tonight, I dont want to go out _______ he phones.（NMET 2000春招）
A. as long asB. in order thatC. in caseD. so that
2. I dont think Ill need any money but Ill bring some _______ .（NMET 2000）
A. at lastB. in caseC. once againD. in time
【考点解析】例1答案为C。in case可引起目的状语从句，表示“以免；以防”，句意为“约翰今晚可能给我打电话，我不想出去以便接他的电话。”此外in case还可单独使用，如例2，答案为B。at last意为“最后”，once again意为“再一次”，in time意为“及时”，只有in case符合句意“我认为我不需要钱但我将带一些以防万一。”
4. be used to句型结构
【课文原句】They are all used to their environment.
【经典考例】In my opinion, life in the twenty-first century is much easier than_____. （2007 安徽）
A. that used to beB. it is used to
C. it was used toD. it used to be
【考点解析】答案为D。used to do sth意为“过去常常……”，表示过去经常发生的动作或存在的状态，而现在不再这样了，含有“今昔对比”的意味；句意“在我看来，21世纪的生活比过去的要容易多了。”be / become used to (doing) sth. 意为“习惯于做某事”，to为介词，后接名词或动词的-ing形式；be used to do sth 意为“被用来做某事”，此结构中的used为动词use的过去分词形式。
5. either… or句型结构
【课文原句】The animal or plant has to either adapt to the change or find a new place.
【经典考例】_______ either he or you going with me when the play _______ here?
A. Is; is put on B. Is; is put upC. Are; is put on D. Are; put up
【考点解析】either… or…意为“或者……或者……”，“不是……就是……”，当连接两个主语时，其谓语动词与最近的一个主语在人称和数上保持一致。本题答案为A。
6. what引导的名词性从句
【课文原句】If we find out more about what we should do, we can help Steven and others like him keeping animals and plants from becoming endangered.
【经典考例】
—What did your parents think about your decision?
—They always let me do _______I think I should.（NMET 2006）
A. whenB. whatC. how D. that
【考点解析】what引导名词性从句，表示“……的事情”，在句中可充当主语、宾语或表语。句中的do后接一个名词性从句做宾语，I should后省略了动词do，故空白处应用what，此处的what相当于the thing that。答案为B。
二、长难句解析
1. You can move any side as many steps as you wish.
句中的as many steps as为同级比较，前一个as是副词，后一个as是连词，故形容词、副词应置于第一个as之后，如又有表示倍数的词修饰则常置于第一个as之前。例如：
You can eatas much as you like.你想吃多少就吃多少。
Americans eat more than twice as many vegetables per person today as they did in 1910.美国人现今每人蔬菜摄食量是1910年的两倍多。
当表示金钱，距离，时间，重量，雨量等概念时，常用as much as结构。例如：
When he worked there, he could earn as much as 500 dollars a week. 当他在那里工作时，一周能挣到500美元。
2. … we may be able to take measures before it is too late, …
句中的before用作连词，引导状语从句，意为“在……之前；还没来得及”。例如：
Three weeks went by before she realized her mistakes. 过了三周，她才意识到自己的错误。
before作连词引导时间状语从句，从句的时态通常用一般现在时代替一般将来时。其基本意思是“在……之前”，但是具体译法视上下文而定。例如：
We do want to buy something now before prices go up. 在物价上涨之前我们的确想买点东西。
Someone called me up in the middle of the night, but they hung up before I could answer the phone.(NMET2000) 半夜里有人给我打电话,可是我还没来得及接,电话就挂断了。
He will die before he will tell them what they want to know. 他宁死也不说出他们想知道的事情。
3. We human beings could not survive without all the plants and animals around us.
句中的without和but for一样引出的短语表示一个非真实的条件，相当于一个if引导的含有否定意义的条件句If there were no all the plants and animals around us。 故句中用了虚拟语气，表示与现在事实相反的假设，例如：
A fish couldnt live long without water. = A fish couldnt live long if there were no water.没有水鱼就活不了多久。
I cant speak English without making mistakes.我一讲英语就出错。
有的语法学家称这种句子为条件否定句，又因为这种句子表示“没有……就不（没有）”的意思，起着强调语气的作用，所以也有的语法学家称之为强调句。现在有不少老师称之为双重否定句是错误的。双重否定的定义是两个否定词用来否定同一个意念或词，表示说话者的踌躇不决，起着缓和语气的作用，例如：
I said so not without any reason. 我这么说不是没有任何理由的。
