作者：贾利民
生活中什么事都可能会“发生（happen）”。那么，你知道怎样使用happen这个词吗？下面我们就对happen的用法作一小结。
happen是不及物动词，它的用法常见的有如下几种情况：
1. 表示“某地（某时）发生了什么事”，常用“sth.+ happen +地点/时间”这一结构来表达，此时主语应是事情。例如：
The story happened in . 这个故事发生在。
An accident happened in that street. 那条街上发生了一起事故。
2. 表示“某人出了某事（常指不好的事）”，要用“sth.+ happen+to sb.”这一结构来表达。例如：
A car accident happened to her this morning. 今天上午她发生了交通事故。
What happened to you? 你怎么啦？
3. 表示“某人碰巧做某事”，要用“sb.+ happen+ to do sth.”这一结构来表达。例如：
I happened to meet a friend of mine in the street yesterday. 昨天我碰巧在街上遇到了我的一个朋友。
4. happen表示“碰巧或恰巧发生某事”时，还可用“It happens / happened that…”这一结构来表达。例如：
It happened that Brian and Peter were at home that day. 碰巧那天布莱恩和彼得在家了。
It happened that he had to take part in a meeting that afternoon. 碰巧那天下午他不得不参加一个会议。
注：that从句中的主语是人时，此种结构可以与“sb.+ happen + to do sth.”结构互换。例如：
It happened that Brian and Peter were at home that day. = Brian and Peter happened to be at home that day.
情态动词used to在句子中的用法
一、Used to表示过去的习惯动作或状态，现在已不存在，在间接引语中，其形式可不变。如：
1.He told us he used to play football when he was young.
他告诉我们他年轻时经常踢足球。
2.I weigh less than I used to.
我的体重比以前轻了。
3.He is used to eating out all the time.
他已经习惯在外面吃饭了。
4.You’ll get used to it.
你会习惯的。
5.Are you used to the food here?
你习惯吃这儿的饭菜吗?
6.I used to get up early and take an hour’s walk before breakfast.
我过去常常起床很早并且在早餐前散步一小时。
7.Women used to think they were on the shelf at 30.
过去女人一到30岁就认为是过了结婚年龄。
8.Jack used to assist Mary in her lessons.
杰克过去常常帮助玛丽学习功课。
二、在疑问句、否定句、否定疑问句或强调句中，可有两种形式：
1、疑问句
Did you use to go to the same school as your brother?
Used you to go to the same school as your brother?
2、否定句
I usedn’t to go there.
I didn’t use to go there.
3、否定疑问句
Usen’t you to be interested in the theatre?
Didn’t you use to be interested in the theatre?
4、强调句
I certainly used to smoke,but it was a long time ago.
I certainly did use to smoke,but it was a long time ago.
5、其反意疑问句或简略回答中，也有两种形式：
She used to be very fat,didn’t she? (口语+常用)/ use(d)n’t she? (正式+过时)
Did you use to play chess? Yes,I did.
Used you to get up early in the morning? Yes,I did. (Yes,I used to.)
Used to 用法小结
01 一、掌握used to的构成
used to+动词原形，其中to是不定式符号
02 二、掌握used to用法。
used to do sth. 过去常常做某事，它没有人称和数的变化。
其用法有三：
1. 表示过去存在而今不复存在的习惯行为或状态，意为：“过去常常”，其中to不定式符号，后接动词原形，表示今昔对比。如：
I used to walk to school, but now I am used to taking the school bus to school.
我过去常常走路上学，但现在我习惯坐校车上学。
2. used to 与there be 结构连用，表示“过去存在的状态”，而现在不存在此类状态了。如：
There used to be a lot of trees here.这里原来有许多树。(意味着现在没有了)
3. used to 与always， often， sometimes等频度副词连用时，并非表示现在的动作或现在的习惯，仍表示过去习惯、过去经常反复发生的动作或存在的状态。如：
She used to write to her father with pens. 她过去经常用钢笔写信给她父亲。
03 三、掌握used to 的句子结构。
1. used to的肯定句结构
主语+used to+动词原形……如：
I used to go to the cinema, but I never have time now. 我过去经常去看电影，但现在没有时间了。
2. used to的否定句结构，其否定结构有两种形式。
⑴ 主语+did not use to+动词原形……，这种否定句型，就是把used当做实义动词来看，所以变否定句要用助动词did，是美式英语用法。如：
You used to drink. →You didn’t use to drink.
② 主语+used not to+动词原形……，这种否定句是把used当做情态动词，变否定句直接在used后面加not即可，used not可以缩写成usedn’t，是英式英语用法。如：
The shop used to open on Sungdays.→ The shop usedn’t to open on Sunday.
3. used to的一般疑问句结构，其一般疑问句有两种形式。
⑴ Did+主语+use to+动词原形……?这种一般疑问句，就是把used当做实义动词来看，所以变一般疑问句时要用助动词did，是美式英语用法。如：
I used to go swimming in the river when I was young.
→Did you use to go swimming in the river when you were young?
⑵ Used+主语+to+动词原形……?这种一般疑问句是把used当做情态动词，所以变一般疑问句时，直接把used提到句首，是英式英语用法。如：
He used to go to school by bike.→ Used he go to school by bike?
4. used to 的肯定和否定回答结构。
used to用于省略句时，肯定式保留to，否定式不保留to。如：
—— Used you play basketball? 你过去常打篮球吗?
——Yes, I used to.(No, I usedn’t.) 是的，经常打。(不，不常打。)
5. used to的反意疑问句，其反意疑问句有两种形式。
⑴ 在附加疑问部分中借助于助动词did构成，这种反意疑问句，就是把used当做实义动词来看，所以变反意疑问句时要用助动词did，是美式英语用法。如：
She used to go to work by bus, didn’t she?
She didn’t use to do it, did she?
⑵ 在附加疑问部分中直接使用usedn’t。这种反意疑问句是把used当做情态动词，所以变反意疑问句时，直接用used，是英式英语用法。如：There used to be a bookshop here, usedn’t there?
6. used to通常不能与表示次数(如twice, three times 等)或一段时间(如three months, five years等)的词连用。如： 我去过巴黎3次。
正：I went to Paris three times. 误：I used to go to Paris three times
04四、掌握易混词组拓展辨析。
used to do sth.; be used to doing sth.; be used to do sth.; be used for doing sth.; be used as sth. be used by sb.
1. used to do sth. 意为“过去经常做某事”，其中的to是不定式符号，而不是介词，所以其后只接动词原形，不能接动名词。如：
He used to live in Paris. 他过去一直住在巴黎。
2. be used to doing sth. 意为“习惯于做某事”，其中的to是介词，所以其后要接名词或动名词，不能接动词原形;若要强调从不习惯到习惯的过程，用get, become 等代替动词be。如：
He is used to looking after himself. 他已习惯于自己照顾自己。
3. be used to do sth. 意思是“被用来做某事”，其中to是不定式符号，所以其后要接动词原形，等于be used for doing sth.。如：
Knives are used to cut things.=Knives are used for cutting things.小刀是用来切东西的。
4. be used as sth. 意思是“被作为……用”。如：
This book can be used as a text book. 这本书可以被当作课本用。 。
5. be used by sb. 意思是“被某人使用”。如：
The machine is used by workers. 这台机器是工人们使用的。
English is used by people in many countries. 英语被许多国家的人使用。
05 五、掌握used to与would的不同用法
1. 两者都表示过去的习惯，当表示过去习惯性的动作时，可互换。如： When we were children we would [used to] go skating every winter. 我们小时候，每年冬天都去溜冰。
2. 若表示过去持续的状态，通常只用used to，不用would。如：
He used to like you. 他原来还是喜欢你的。
He is not what he used to be. 他已不是从前的他了。
3. 若要强调过去与现在的对比，也通常只用used to。如：
I don’t smoke these days, but I used to. 我现在不抽烟，但我以前是抽的。
I used to drive to work, but now I cycle. 过去我常驾车上班，但我现在骑自行车 。

五分钟搞懂used to的用法区分
基本用法
used to意为“过去常常，过去是”，其后跟动词原形，表示过去存在的某种状态或过去某种经常性、习惯性的行为或动作，并意味着这种情况目前已不复存在，侧重于过去与现在的对比。used无人称和时态的变化。
We used to go there every year.
我们以往每年都去那里。
I used to get up at six in the morning ,but I usually get up at half past five now.
我过去常常早上六点起床，但是现在我通常五点半起床。
Tina is not what she used to be .
蒂娜已经不再是过去的她了。
The old man used to be an excellent player.
那位老人曾是一名出色的运动员。
否定句式
used to 的否定形式是didn’t use to 或used not to ,后者可缩写成usedn’t to ,在口语中常用didn’t use to 进行否定。
She didn’t use to /used not to /usedn’t to play computer games .
她过去不常玩电脑游戏。
一般疑问句式
used to 变一般疑问句可以用Did sb.use to …?或Used sb. to …?
Did you use to /Used you to play football?
你以前经常踢足球吗?
Didn’t your uncle use to /Usedn’t your uncle to live in Beijing?
你叔叔过去不是一直住在北京吗?
反意疑问句
used to 在变反意疑问句时，它的附加问句部分可以用didn’t 或usedn’t .
Martin used to go out for a walk after supper,didn’t /usedn’t he?
马丁过去常常晚饭后出去散步，是不是?
Yes ,he did ./Yes ,he used to .
是的，他过去是这样。
No,he didn’t ./No, he usedn’t to .
不是，他过去不是这样。
英语中的【used to】和【 use to】用法的区别在哪里呢?
used to和be used to的用法与区别
be used to为被动语态。意为“被用来……”，为动词不定式符号，其后跟动词原形。例如：
①Golden trumpets are used to express public opinion here.
这儿金喇叭是用来表达公共舆论的。
②Bamboo can be used to carry water.竹子可用来输水。
【注意】若“used to”后接动词原形，意思是“过去常常”，表示过去经常发生的动作(或存在的状态)现在已不再发生(或存在)了。
例如：
①People used to think the sun travelled round the earth.人们过去曾经认为太阳绕地球转动。(暗指人们现在并不这样认为了。)
used to的否定式可用didn’t use to,或used not to
(缩写为usedn’t to或usen’t to读音为[‘ju:snt]。
若“be used to+名词或v-ing”意思是“习惯于”。试比较：
①He used to walk to school.他过去总是步行到校。
②He is used to walking to school. 他现在习惯于步行上学了。
值得注意的是：
1)used to只用于过去时，不能用于别的时态;be used to则可用于各种时态。例如：
①He is (was, will be, has been, etc.) used to walking to school.
2)be used to 中的be可以用 get, become, grow代替，用这些动词构成的动词词组表示由不习惯到习惯的过程。例如：
①You’ll soon get used to the life in the countryside.
你很快就会习惯乡下的生活的。
Used to 用法小结
as可以作连词、介词及关系代词。现将其用法小结如下:
一、as作连词的用法:
1. 作“当……的时候”,引导时间状语从句。注意与when、while的用法区别。
① when作“当……的时候”解,可以指较短的(一点)时间,也可指一段时间。如:
When he was at college, he could speak several foreign languages. (表示一段时间)
When the clock struck twelve, all the lights in the street went out. (表示时刻)
② while常表示一段较长的时间或一个过程,强调主句谓语动词与从句谓语动词同时发生。如:
Work while you work. Play while you play.
③ 但属下列情形时,只用as, 而不用when或while。
A) 用于表示同一个人的两种动作交替进行,指“一边……,一边……”。如:
The girl dances as she sings on the stage.
He looked behind from time to time// as he went forward.
B)表示两个同步发展的动作或行为,译为“随着……”。如:
As time went on / by, she became more and more worried.
As children get older, they become more and more interested in the things around them.
C)表示两个短促行为或事件几乎同时发生。如:
I thought of it //just as you opened your mouth.
Just as the flying worm hit her face, she gave a loud cry.
D) 后接名词表示某一年龄段时,用as。如:
As a young man, he was active in sports.
2. as=since, 作“既然”、“由于”解,引导原因状语从句,常用来表示已为人们所知或显而易见的原因或理由。如:
As / Since you’re not feeling well, you may stay at home.
As he wasn’t ready in time, we went without him.
3. as=in the way that, 作“像”、“按照……的方式”解,引导方式状语从句。如:
He speaks English as Americans do.
Remember, you must do everything as I do.
4. 用于as…as…或not so/ as…as…中,前一个as是副词(副词后面跟形容词、动词、副词),后一个as是连词(连词后面可以跟动词、形容词、句子),引导比较状语从句。如:
They helped the old man as often as possible.
I don’t speak English so/ as well as he does.
5. 作“虽然”、“尽管”解,引导让步状语从句。常用倒装语序,即adj. /adv. / n.+ as +主语+谓语+主句。如:
Tired as they were, they walked on.
Child as he is, he knows a lot. (child前不用冠词)
二、as作关系代词,引导定语从句,作“正如”、“这一点”解。如:
He is very careful, as his work shows.
As is well-known, Taiwan belongs to China.
另外,当先行词被the same, such等词修饰时,常用as来引导定语从句。如:
Such a clever boy as he can learn anything quickly.
I was reading the same book as he bought yesterday.
三、as作介词的用法:
as引导的介词短语大多用作状语,as译为“作为”;少数情况可引起宾语补足语。如:
As a League member, I’ll take the lead in everything. (状语)
She works as a doctor. (状语)
They have me as one of their own children.(引起宾语补足语)
【英语】分析长难句必备语法点：as用法总结
as主要词性
as 主要有两种词性，分别为介词和连词，并且出现在as…as…这样的固定结构中。as作为介词时，常与一些动词搭配使用，比如view… as… (把……当作)，regard… as…(把……当作) refer to…as…(把……称作) ，use…as (把……用作)。
真题例如：Many consumers seem to have been influenced by stock-market swings, which investors now view as a necessary ingredient to a sustained boom. (Text 3)
这里的as结构是view… as… ，view的宾语是关系代词which，它指代前面的先行词stock-market swings，这句话翻译为：许多消费者已经受到股票市场波动的影响，而投资者们正在将这些波动视为经济长期繁荣必要因素。
as作为连词词性时，可以引导各类从句。
as 引导定语从句
as引导定语从句时，既可以引导限制性定语从句，又可以引导非限制性定语从句。as引导限制性定语从句可见于such…as结构中，可代替先行词或物的名词。如Let’s discuss only such problems as concern us.让我们只讨论与我们有关的问题。as还可引导非限制性定语从句，代替整个主句，对其进行说明。如As might be expected, the response to the question was very mixed. As代替后面的主句，在从句中做主语。正如所料，人们对于这个问题的观点不一。
as引导让步状语从句
as引导让步状语从句, 此时相当于although，意思是虽然，尽管。as引导的让步状语从句一律采取倒装形式。如Angry as he was, he couldn’t help smiling.尽管他很生气，但他还是忍不住笑了。
真题例句：Symbolic of national unity as they claim to be, their very history-and sometimes the way they behave today-embodies outdated and indefensible privileges and inequalities.(Text 1)
前半句话是由as引导的让步状语从句，是部分倒装结构，正常语序为as they claim to be symbolic of national unity，修饰主句。
译文：尽管他们宣称自己代表着国家统一，但是正是他们以往的历史以及现在有时的行为方式体现了已经过时的、站不住脚的特权和不公平。
as引导时间状语从句
as引导时间状语从句，可以翻译成“当……时候;随着……”如He gets more attractive as he gets older. 随着年龄的增长，他变得愈发有魅力。
真题例句：
Now utopia has grown unfashionable, as we have gained a deeper appreciation of the range of threats facing us, from asteroid strike to epidemic flu and to climate change.(Text 3)
译文：现如今这种空想的美好社会已经过时了，我们对面临的威胁范围有了更深刻的认识，从彗星撞击到流行感冒，再到气候变化。
as引导原因状语从句
as引导原因状语从句，表示的是双方都知道的原因。可翻译成既然，由于。如As it was getting late, I decided to book into a hotel.因为天色已晚，我决定找间饭店投宿。
as引导的方式状语从句
as表示按照，以……方式，像……一样，正如。如Careful surveys have indicated that as many as 50 percent of patients do not take drugs as directed.这里的as是以……方式，按照。这句话翻译为仔细的调查表明，多达50%的病人未按规定服药。
as引导的比较状语从句
as引导比较状语从句，其基本结构是as…as。前一个as是副词，后一个as是比较状语从句的连词。如It’s not as good as it used to be.这个不如以前的好。
高中英语语法知识点：as…as…用法小结
(1)…as+形容词(副词)原级+as…;not as/so+形容词(副词)原级+as…
Their factory is as large as ours.他们的工厂和我们的一样大。

Although he is young, he knows a lot.
=Young as he is, he knows a lot.

4.as for / as to
两者都可以表示“至于”。as for 更倾向于比较性，两者有一定的对比。有时可以包含说话人的一种轻蔑、冷淡、不屑、甚至是厌恶之感;as to更倾向于客观陈述，谈话的内容大家都有所了解。
You can have a bed; as for him, he’ll have to sleep on the floor.
你可以有张床，至于他嘛，打地铺去吧。
As to your ability to overfulfil the target, I never had the slightest doubt.

好了，今天就先聊这些吧，现在终于是把as完全弄清楚了。

百分比?percent、per cent、percentage
先从释义和例句，直观地看看这三个词是什么意思?
1、percent
n. 百分之…
The net income per head rose by about 16 percent in the past three years.
在过去的三年里每人的净收入增长了大约 16%。
There is a Green party but it only scored about 10 percent in the vote.

2、per cent
20 to 40 per cent of the voters are undecided.
20% 到 40% 的选民还犹豫不决。
We aim to increase sales by 10 per cent.
我们的目标是将销售额提高10%。
3、percentage
n. 百分率;百分比
A high percentage of the female staff are part-time workers.
女职员中，兼职工作的人占很高的比例。
What percentage of the population is/are overweight?
身体超重的人占人口多大的百分比?
现在进行区分：
(1)从词义和用法上，percent 和 per cent 完全相同。 英国习惯用per cent，而美国习惯用 percent。
现在来区分 percent 和 percentage：
(2)从用法上，percent 是跟在 数字 后面的，意思上是代替 %(单位)。
如 16 percent 对应的中文是16 %。
而 percentage 不能 和数字一起用。 意思上是表示 百分比。 常用的用法是：(the / a percentage of sth)(一个东西的百分比) 对应什么变化、是多少。
可以说 a small percentage 或 a large percentage，形容百分比大小，但是就是不能跟数字一起用。
as if 用法
一、as if 从句的作用
1. 在look, seem 等系动词后引导表语从句。
如：
She looks as if she were ten years younger.
她看起来好像年轻了十岁。
It seems as if our team is going to win.
看来我们队要胜了。
2. 引导方式状语从句。
如：
She loves the boy as if she were his mother.
她爱这男孩，就好像她是他的母亲一样。
The child talked to us as if he was a grown up.
那孩子跟我们谈起话来，像个成年人似的。
二、as if 还可用于省略句中如果as if 引导的从句是“主语+系动词”结构，可省略主语和系动词，这样as if 后就只剩下名词、不定式、形容词(短语)、介词短语或分词。
如：
He acts as if (he was) a fool.
他做事像个傻子。
Tom raised his hands as if (he was going) to say something.
汤姆举起手好像要说什么。
She left the room hurriedly as if (she was)angry.
她匆忙离开房间好像生气的样子。
三、as if 从句的语气及时态
1. as if 从句用陈述语气的情况。 当说话者认为句子所述的是真实的或极有可能发生或存在的事实时。
如：
It sounds as if it is raining.
听起来像是在下雨。
He talks as if he is drunk.
从他谈话的样子来看他是醉了。
2.as if 从句用虚拟语气的情况。 当说话人认为句子所述的是不真实的或极少有可能发生或存在的情况时。从句虚拟语气动词时态的形式如下：
(1)如果从句表示与现在事实相反，谓语动词用一般过去时。
如：
You look as if you didn’ t care.
你看上去好像并不在乎。
He talks as if he knew where she was.
他说话的样子，好像他知道她在哪里似的。
(2)从句表示与过去事实相反，谓语动词用“had+过去分词”。
如：
He talks about Rome as if he had been there before.
他说起罗马来好像他以前去过罗马似的。
The girl listened as if she had been turned to stone.
那女孩倾听着，一动也不动，像已经变成了石头似的。
(3)从句表示与将来事实相反，谓语动词用“would/could/might+动词原形”。
如：
He opened his mouth as if he would say something.
他张开嘴好像要说什么。
It looks as if it might snow.
看来好像要下雪了。
语法学习：as if虚拟语气的用法
as if虚拟语气的用法
有时用虚拟语气，若表示与现在事实相反，谓语动词用一般过去时;若表示与过去事实相反，用过去完成时;表示将来的可能性不大，用would (might, could)+动词原形。
(1) 从句所表示的内容若为事实或可能为事实，也可用陈述语气：
例：It looks as if we’ll be late.
我们似乎要迟到了。
This meat tastes as if it has already gone bad. 这
肉吃起来似乎已经坏了。
在现代英语中，有时即使从句内容不是事实，也可能用陈述语气：
例：
I feel as if [as though] I’m floating on air.
他感到好像漂浮在空中。
The stuffed dog barked as if it is [were, was] a real one.
玩具狗叫起来像真狗。
(2) 注意 It isn’t as if…的翻译：
例：
It isn’t as if he were poor.
他不像穷的样子(或他又不穷)。
It isn’t as if you were going away for good.
又不是你离开不回来了。

6. 关于 as…as, 用法注意：
(1) 中间只能用形容词或副词的原级，不能用比较级或最高级。如果在第二个as之后使用独立的人称代词，一般说来用主格 (较正式)或宾格 (非正式)均可。如：
He’s as old as she
her. 他年纪跟她一样大。
注意：
要是第二个as之后的人称代词跟有谓语动词，则该人称代词只能用主格。如：
He is as old as she is.
但是有时用主格或宾格含义差别很大。如：
You love him as much as I (=as I love him). 你爱他像我爱他一样。
You love him as much as me (=as you love me). 你爱他像爱我一样。
(2) 在肯定句中用as…as, 在否定句中用not as…as或not so…as 均可。如：
He doesn’t study as [so] hard as his brother. 他学习不如他弟弟努力。
(3) 要注意比较对象的一致性，即比较的双方必须是可以比较的的同类人或物，否则会出错。如：
正：The population of China is much larger than that of Japan. 中国人口比日本人口多得多。
误：The population of China is much larger than Japan.
(此句错在将 the population of China 与 Japan 来比较，比较对象不一致)
(4) 如果涉及数量或程度，可用以下两个结构。如：
①as much+ (不可数名词+) as
②as many+ (可数名词复数+) as
You must speak English as much as possible. 你必须尽可能地多说英语。
You’ve made as many mistakes as I have. 你犯的错误和我犯的一样多。
(5) 请注意下列结构的词序。如：
她和她妈妈一样是位好厨师。
正：She is a cook as good as her mother.
正：She is as good a cook as her mother.
误：She is as a good cook as her mother.
(6) 修饰as…as结构的常见词语有nearly, almost, just, exactly, half, quite, twice, three times等，请注意这些修饰语都只能放在as…as 结构之前 (而不能置于其中或其后。如：
This rope is twice aslong as that one. 这根绳子比那根长一倍。
(7) as…as结构的下列用法，属于“异质比较” (注：主、从句的主语和谓语一致时，从句的主语和谓语有时可以省略)。如：
The room is aslong as (it is) wide. 这房间的长宽尺寸一样。
The news was asunexpected as (it was) welcome. 这消息来得突然，但受人欢迎。
She is as clever as (she is) beautiful. 她既聪明又漂亮。
Oneis as light as the other is heavy. 一个轻，另一个重。
(8) as…as结构在一定的上下文中可以用其省略结构 (即省去其中的一个 as)。如：
She’s clever, but her brother is just as clever. 她很聪明，但她兄弟也一样聪明。
The woman married a man pooras herself. 这个女人嫁给了一个与她一样穷的男人。
1、others相当于other+复数名词,如：
注意：所指的其他人并非其他所有的人,指其他部分的全部,请看“2、”
ome people like walking.Some like running.Others like swimming.
有些人喜欢散步,有些人喜欢跑步,其他人喜欢游泳.
He is always ready to help others.
他总是乐于助人.
2、the others 其余的，相当于the other的复数形式,特指某一范围内的其他全部,如：
Two boys will go to the zoo,and the others will stay at home.
两个男孩将去动物园,其余的留在家里.
Thirty of them are boy students and the others are girls.
