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.

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。

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。

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.

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。
