I must stop writing now，as I have rather a lot of work to do．我必须停笔了，因为我还有许多工作要做。
3．引导方式状语从句或比较状语从句，作“正如，(如)像”解。例eg：
As in your country，we grow wheat in the north and rice in the south．正如(像)你们国家一样，我们在北方种小麦，在南方种大米。(方式状语从句)
When at Rome，do as Romans do．入乡随俗。(方式状语从句)
4．引导让步状语从句，作“虽然，尽管”解。这时从句常用倒装语序，即把从句中的表语、状语或动词原形放在as之前。eg；
Strange as it may seem，it is true．尽管这事看上去很奇怪，但却是真的。
Try as he might，Tom could not get out of the difficulties．不管怎样努力，汤姆还是摆脱不了困境。
四）as作关系代词。
1．引导限制性定语从句，用在“such．．．as”,“the same．．．as”，“as．．．as”等结构中，常译作“像．．．一样的人(或物)”，“凡是．．．的人(或物)”。例eg：

My hometown is no longer the same as it was．我的家乡再也不像过去一样了。
2．引导非限制性定语从句，用来指代它前面的整个句子(即先行句)，意思是“这一点”。这个分句可以位于句首、句中或句末。eg：

五）含as的固定词组的用法

2．as／so long as作“只要”解，eg；
As／So long as you study hard，you'll make progress．只要你努力，你就会取得进步。

as...as的用法
as...as意为"和……一样"，表示同级的比较。使用时要注意第一个as为副词，第二个as为连词。其基本结构为：as+ adj./ adv. +as。例如：
(1)This film is as interesting as that one.这部电影和那部电影一样有趣。
(2)Your pen writes as smoothly as mine.你的钢笔书写起来和我的一样流畅。
其否定式为not as/so +adj./ adv. +as。例如：
This dictionary is not as/so useful as you think.这本字典不如你想象的那样有用。
若有修饰成分，如twice, three times, half, a quarter等，则须置于第一个as之前。例如：
Your bag is twice as expensive as mine.你的袋子比我的贵一倍。
几个关于as...as的常见句型：
(1)as...as possible
Please answer my question as soon as possible.请尽快回答我的问题。
(2)as...as usual/before
She looks as pretty as before.她看起来和以前一样漂亮。
(3)as long as... (引导条件状语从句)

(4)as far as
He walked as far as the railway station yesterday evening.昨天傍晚，他一直散步到火车站。

一些带有as...as结构的常见短语归纳：

as easy as ABC像ABC一样容易
as deep as a well像井一样深
as light as a feather像羽毛一样轻
as soft as butter像黄油一样软
as rich as a Jew像犹太人一样富裕
[解题过程]
as + 形容词或副词原级+ as
1）在否定句或疑问句中可用so… as。He cannot run so/as fast as you.
2）当as… as 中间有名词时采用以下格式。
as +形容词+ a +单数名词
as + many/much +名词
This is as good an example as the other is.
I can carry as much paper as you can.
3）用表示倍数的词或其他程度副词做修饰语时，放在as的前面。
This room is twice as big as that one.
Your room is the same size as mine.
4) 倍数+ as + adj. + as<=> 倍数+ then + of
This bridge is three times as long as that one.
This bridge is three times the length of that one.
Your room is twice as large as mine.
Your room is twice the size of mine.
necessary+for还是to?
一般情况下是+ to,若是表示“对某人有必要的、是必须的”之意，即necessary后面直接跟人称代词，就+ for。看一些例句就知道了：
1）Sleep is necessary to health. 睡眠对健康是必要的。
2）Sometimes it is not necessary to go inside in order to buy the hamburgers.
有时候要买汉堡包不需要进入这些餐馆。
3）It is necessary for older people to understand what they think and feel.
年长的人有必要了解年青人在想些什么,他们有什么感觉。
“It’s +adj.+of+sb.+to do”和“It’s+adj.+for+sb.+to do”区别
It is+adj.+of sb. +to do sth中的adj.跟sb.有关,
这个adj.是用来形容sb.的,
表示某人这么做真是太adj.了．
你会发现在这个句型中你把sb.和adj.提出来可以造个句sb. is(are) adj.
如It's very kind of you to help me.
把里面的sb.和adj.提出来可以发现you are kind是说得通的.
而It is +adj.+for sb.+to do sth表示做某事对某人来说很adj.
这里的adj.是do sth.的属性
里面的sb.跟adj.没有直接联系
如It's difficult for you to deal with the problem.
你就不能说you are difficult了吧
It's adj of sb to do sth 中adj 是针对事件，修饰sb
It's adj for sb to do sth 中adj 是针对sb，修饰事件
用of常用于描述人的性质友好、可恨、善良等。
用for常用于描述事情的性质容易、重要、关键
例如：It”s very nice (kind, friendly) of you to help me carry the baggage.你真友好，帮我搬了行李。
It” s very important for you to solve the problems.
解答出那些难题对于你来说非常主要。

as well 与as well as的用法区别
as well 与as well as的用法区别
as well与as well as只有一词之差，但意义和用法却相差甚远。
一、as well 用法：
1、as well常用作状语，作“又；也”解，相当于too或also，常位于句末，无须用逗号与句子分开。如：
I am going to London and my sister is going as well（＝going，too）.
我要到伦敦去，我妹妹也要去。
I not only play the guitar，I sing as well（＝I also sing ）.
我不但弹吉他，而且还演唱。
2、as well 在口语中也可用于句中，作“也好，也行”或“倒不如”解，用来缓和语气。如：
You may as well go、你去也好。
The weather was so bad that we might（just）as well have stayed at home.
天气太坏了，早知道如此，倒不如呆在家里为好。
3、as well 可以直接用于just后，用作应答语（可视为It's just as well、的省略），作“幸亏，幸而；无妨；没关系”解。如：
—We were too late to see the film.我们去得太晚了，没有看上电影。
—Just as well、I hear it isn't very good.不必遗憾，我听说电影也不怎么样。
二、as well as 用法
1、as well as常用来连接两个并列的成分，作“也，还”解。它强调的是前一项，后一项只是顺便提及。因此连接并列主语时，谓语动词与前一项一致；而用not only ...but also...连接时，谓语动词与后一项
一致。如：
Your wife as well as you is friendly to me.不仅你而且你的妻子也对我很友好。
（＝Not only you but also your wife is friendly to me、）
Electric energy can be changed into light energy as well as into sound energy.
电能既可以被转变成声能，又可以被转变成光能。
2、as well as 用来表示同级比较，指“一样好”。如：
You look as well as you did ten years ago.你的身体看起来还和十年前一样好。

With的用法全解 with结构是许多英语复合结构中最常用的一种。学好它对学好复合宾语结构、不定式复合结构、动名词复合结构和独立主格结构均能起很重要的作用。本文就此的构成、特点及用法等作一较全面阐述，以帮助同学们掌握这一重要的语法知识。 一、 with结构的构成 它是由介词with或without+复合结构构成，复合结构作介词with或without的复合宾语，复合宾语中第一部分宾语由名词或代词充当，第二部分补足语由形容词、副词、介词短语、动词不定式或分词充当，分词可以是现在分词，也可以是过去分词。With结构构成方式如下： 1. with或without-名词/代词+形容词； 2. with或without-名词/代词+副词； 3. with或without-名词/代词+介词短语； 4. with或without-名词/代词 +动词不定式； 5. with或without-名词/代词 +分词。 下面分别举例： 1、 She came into the room，with her nose red because of cold.（with+名词+形容词，作伴随状语）

其基本意思为“与…一样”，其中的第一个as为副词，其后通常接形容词或副词(用原级)，第二个as可用作介词(后接名词或代词)或连词(后接从句)。使用时应注意以下几点。如： (1) 在否定句中，第一个as 也可换成so。如： He doesn’t study as [so] hard as his brother. 他学习不如他弟弟努力。 (2) 在该结构的两个as之间通常接形容词或副词的原级，但若涉及数量或程度，可用“as much+不可数名词+as”和“as many+复数名词+as”。如： You’ve made as many mistakes as I have. 你犯的错误和我犯的一样多。 I haven’t got as much money as I thought. 我不像原来想像的有那么多钱。 其间接形容词时，有时该形容词还可修饰另一名词，但这个名词应带有不定冠词(注意词序)。如： She is as good a teacher as her mother. 她和她妈妈一样是位好老师。 也可说。如：She is a teacher as good as her mother. 但不说。如：She is as a good teacher as her mother. / They are as good teachers as us. (3) 第二个as后接从句时，该as通常为连词，但有时这个as还充当其后从句的主语或宾语，此时该as实为关系代词。如： I gave him as much as he could eat. 他能吃多少，我就给了他多少。 We’ve got food for as many people as want it. 我们的食物，无论多少人吃都够了。 (4) 该结构根据情况可用使用以下修饰语。如：(not) nearly, almost, just, nothing like, exactly, not quite, half, one-ten, twice, three times, 30 per cent等，并且这些修饰语必须置于第一个as之前，而不能置于其后。如： He doesn’t play half as well as his sister. 他演奏的水平不及他姐姐的一半。 This dress is twice as expensive as that. 这件连衣裙比那件贵一倍。 (5) 若第二个as引导一个表示将来意义的从句，则该从句可用现在时表示将来，也可直接使用将来时态。如： We’ll get there as soon as you do [will]. 你一到，我们就到。
with用法归纳 （1）“用……”表示使用工具，手段等。例如： ①We can walk with our legs and feet. 我们用腿脚行走。 ②He writes with a pencil. 他用铅笔写。 （2）“和……在一起”，表示伴随。例如： ①Can you go to a movie with me? 你能和我一起去看电影'>电影吗？ ②He often goes to the library with Jenny. 他常和詹妮一起去图书馆。 （3）“与……”。例如： I’d like to have a talk with you. 我很想和你说句话。 （4）“关于，对于”，表示一种关系或适应范围。例如： What’s wrong with your watch? 你的手表怎么了？ （5）“带有，具有”。例如： ①He’s a tall kid with short hair. 他是个长着一头短发的高个子小孩。 ②They have no money with them. 他们没带钱。 （6）“在……方面”。例如： Kate helps me with my English. 凯特帮我学英语。 （7）“随着，与……同时”。例如： With these words, he left the room. 说完这些话，他离开了房间。 [解题过程] with结构也称为with复合结构。是由with+复合宾语组成。常在句中做状语，表示谓语动作发生的伴随情况、时间、原因、方式等。其构成有下列几种情形： 1.with+名词(或代词)+现在分词 此时，现在分词和前面的名词或代词是逻辑上的主谓关系。 例如:1)With prices going up so fast, we can't afford luxuries. 由于物价上涨很快，我们买不起高档商品。（原因状语） 2)With the crowds cheering, they drove to the palace. 在人群的欢呼声中，他们驱车来到皇宫。（伴随情况） 2.with+名词(或代词)+过去分词 此时，过去分词和前面的名词或代词是逻辑上的动宾关系。

With复合结构的用法小结 with结构是许多英语复合结构中最常用的一种。学好它对学好复合宾语结构、不定式复合结构、动名词复合结构和独立主格结构均能起很重要的作用。本文就此的构成、特点及用法等作一较全面阐述，以帮助同学们掌握这一重要的语法知识。 一、with结构的构成 它是由介词with或without+复合结构构成，复合结构作介词with或without的复合宾语，复合宾语中第一部分宾语由名词或代词充当，第二 部分补足语由形容词、副词、介词短语、动词不定式或分词充当，分词可以是现在分词，也可以是过去分词。With结构构成方式如下： 1. with或without-名词/代词+形容词； 2. with或without-名词/代词+副词； 3. with或without-名词/代词+介词短语； 4. with或without-名词/代词+动词不定式； 5. with或without-名词/代词+分词。 下面分别举例： 1、She came into the room，with her nose red because of cold.（with+名词+形容词，作伴随状语） 2、With the meal over ，we all went home.（with+名词+副词，作时间状语） 3、The master was walking up and down with the ruler under his arm。（with+名词+介词短语，作伴随状语。）The teacher entered the classroom with a book in his hand. 4、He lay in the dark empty house，with not a man ，woman or child to say he was kind to me.（with+名词+不定式，作伴随状语）He could not finish it without me to help him.（without+代词+不定式，作条件状语） 5、She fell asleep with the light burning.（with+名词+现在分词，作伴随状语）Without anything left in the cupboard，shewent out to get something to eat.（without+代词+过去分词，作为原因状语） 二、with结构的用法 在句子中with结构多数充当状语，表示行为方式，伴随情况、时间、原因或条件（详见上述例句）。 With结构在句中也可以作定语。例如： 1.I like eating the mooncakes with eggs. 2.From space the earth looks like a huge water-covered globe with a few patches of land sticking out above the water. 3.A little boy with two of his front teeth missing ran into the house. 三、with结构的特点 1. with结构由介词with或without+复合结构构成。复合结构中第一部分与第二部分语法上是宾语和宾语补足语关系，而在逻辑上，却具有主谓关系，也就是说，可以用第一部分作主语，第二部分作谓语，构成一个句子。例如：With him taken care of，we felt quite relieved.（欣慰）→（He was taken good care of.）She fell asleep with the light burning. →（The light was burning.）With her hair gone，there could be no use for them. →（Her hair was gone.） 2. 在with结构中，第一部分为人称代词时，则该用宾格代词。例如：He could not finish it without me to help him. 四、几点说明： 1. with结构在句子中的位置：with 结构在句中作状语，表示时间、条件、原因时一般放在
get的各种用法，你get到没？ Do You Get It “ Get是大家最为熟悉的几大动词之一了，不过你确定完全get了这个词的用法了吗？好词要充分利用啊，我们来仔细整理一下它的用法。 1 receive / have 得到 Are you getting a refund? 你能拿到退款么？ Are you getting any reception? 有人招待你吗？ Don't expect to get a high-paying job right out of school. 别刚一毕业就期待能得到高薪的工作。 Can I get change for a twenty? 我能换20块的零钱么？ It's super important that I get this internship. 得到这份实习对我来说超级重要。 Let's get an objective opinion.

这是折扣的时候买的，我只花了四块钱。 I only got four hours of sleep last night. 我昨晚只睡了四个小时。 I've gotten a lot of positive feedback on it. 我收到了很多积极反馈。 2 become 变成 I can definitely tell you're getting better. 我可以明显看出来你正在好转。 I get distracted so easily! 我很容易分心。 I want to try to shed a few pounds and get back in shape. 我想要减轻体重，恢复原来的体形。 It's getting harder and harder to earn a living as a photographer these days. 现在当摄影师，真是越来越难过活了。 3 go / come / arrive 去、来、到达
第一个as是副词，第二个as是连词as用法小结 一）as作副词，表示程度，意为“同样地”。在“as．．．as．．．”，“not as．．．as．．．”结构中的第一个as是副词，作“和／与．．．(不)一样”解。eg： Jack is as tall as his father．杰克和他的父亲一样高。 He doesn't speak English as／so fluently as you．他的英语说得不如你流利。 二）as作介词。 1．作“如，像”解。eg： They got united as one man．他们团结得像一个人一样。 2．作“充当，作为”解。eg： As a writer，he was famous．作为作家，他是很有名的。 三）as作连词，常用来连接主句和状语从句。 1．引导时间状语从句，作“当．．．的时候”解，有“随着．．．”之意，与while意义相近，强调两个动作同时发生；或某事一发生，另一事立即发生。eg： He shouted aloud as her ran along．他一边往前跑，一边高声地呼喊。 I was startled as he opened the door．他一开门，我吓了一跳。 as作连词，相当于when。eg； As a little boy (When he was a little boy)he began to learn to play piano．他小时候就开始学弹钢琴。2．引导原因状语从句，作“因为，由于”解，与because的用法相近。eg； I must stop writing now，as I have rather a lot of work to do．我必须停笔了，因为我还有许多工作要做。 3．引导方式状语从句或比较状语从句，作“正如，(如)像”解。例eg： As in your country，we grow wheat in the north and rice in the south．正如(像)你们国家一样，我们在北方种小麦，在南方种大米。(方式状语从句) When at Rome，do as Romans do．入乡随俗。(方式状语从句) 4．引导让步状语从句，作“虽然，尽管”解。这时从句常用倒装语序，即把从句中的表语、状语或动词原形放在as之前。eg； Strange as it may seem，it is true．尽管这事看上去很奇怪，但却是真的。
