sure与certain的用法与区别 篇一

一、两者在用法上的相同点

两者都可用作表语,表示“一定”或“确信”,有时可互换。互换的场合应注意以下几点用法:

1. 表示说话者的态度或看法

即表示说话者自己的态度或看法,其意为“一定会”“肯定会”。此时主要用法有:

(1) 单独用作表语。如:

One thing was sure [certain]: they'd be late. 有一件事是确定无疑的,他们会迟到。

(2) 后接不定式。如:

He's certain [sure] to win. 他一定会成功。

They're certain [sure] to need help. 他们肯定需要帮助。

If you do this, you are certain [sure] to be found out. 如果你这样做一定会被发现。

2. 表示句子主语的判断或信念

即表示句子主语对某一情况的判断或信念,其意为“相信”“确信”“有把握”等。此时通常用于以下结构:

(1) 后接of [about] sth。如:

He is certain [sure] of success. 他确信会成功。

Are you certain of [about] that? 你对此有把握吗?

(2) 后接 of doing sth。如:

Our team is certain [sure] of winning. 我们队有把握赢。

You can be sure [certain] of his agreeing. 你可以放心他会同意。

比较同义句:

He is certain [sure] of winning.

=He is sure [certain] that he will win. 他自信会赢。

(3) 后接 that / whether / if 从句。如:

I am sure [certain] that he is honest. 我肯定他是诚实的。

I'm sure [certain] that it's not your fault. 我敢肯定这不是你的错。

Are you certain [sure] that this is the right road? 你肯定这条路对吗?

注:当be sure [certain]为肯定式或疑问式时,后接that从句;当be sure [certain]为否定式时,后接whether [if]从句。如:

I'm not sure [certain] whether he still works there. 我不能肯定他是否还在那里工作。

I wasn't sure [certain] whether he would agree. 我不太肯定他是否会同意。

He wasn't sure [certain] whether he would be able to get back in time. 他不能肯定他是否能准时回来。

(4) 后接其他从句。如:

I'm not sure [certain] where she lives. 我不能肯定她住在哪里。

I'm not certain [sure] who wrote it. 我不太清楚这是谁写的。

二、只能用certain的情形

以下情况通常只用certain,而不用sure:

1. 当句中用了形式主语或形式宾语 it 时。如:

It's certain that he'll come tomorrow. 他明天肯定会来。

I thought it certain that he would be late. 我肯定他会迟到。

It's certain that prices will go up. 价格肯定会上涨。

It's not certain how much it will cost. 这要花多少钱还不确定。

2. 当表示“某一”“某些”时。如:

A certain Mr Green wants to see you. 有个叫格林先生的人想见你。

Certain plants are good to eat but others are not. 有些植物好吃, 而其他一些则不好吃。

三、只能用sure的情形

在 Be sure (not) to do sth.(一定要或不要做某事)这类祈使句中通常不用 certain。如:

Be sure not to forget it. 千万别忘记啦。

Be sure to get there before nine. 务必在九点前到达。

Be sure to turn off the light when leave. 离开时一定要关灯。

四、两者在习语中的用法

1. 用于 for certain / for sure, 意为“肯定地”“确切地”等,两者可互换。如:

I can't say for certain [sure] when he will come. 我不敢肯定地说他什么时候来。

risk的用法 篇二

1. 用作动词时,为及物动词,表示“冒……的危险”“使遭受危险”。如:

They risk their lives in order that we may live more safely. 他们冒了生死危险使我们生活得更安全。

后接动词作宾语时,要用动名词,不能用不定式。如:

They risked losing everything. 他们冒失去一切的危险。

A lot of people run the risk of being killed. 许多人冒着被杀害的危险。

2. 用作名词时,注意以下用法:

(1) 要表示冒危险,通常与动词run, take等搭配。如:

Why run the risk? 为什么要冒这种危险?

There was so much to lose (that) we couldn’t take any risks. 损失这么多,我们不能冒任何风险了。

(2) 表示“……的危险”,其后通常不接不定式,而接 of doing sth。如:

He dare not run [take] the risk of being caught by the police. 他不敢冒被警察抓住的危险。

There’s not much risk of losing money if you bet on that horse. 如果你押那匹马,输钱的风险不太大。

比较run [take] the risk of doing sth与run [take] a risk in doing sth:前者指冒做某事的危险或风险,其中的of doing sth为修饰the risk的定语;后者指做某事有危险或冒风险,其中的in doing sth是状语,in有类似when的含义。如:

I took a risk in telling him the news at that moment. 我那时把消息告诉他,那是冒了风险的。

(3) 注意以下习语的用法:

①at risk 处境危险,在危险中

How much at risk is the smoker? 吸烟者的危险性有多大?

②at one’s own risk 对发生的事负责,自担风险

Persons swimming beyond this point do so at their own risk.游泳者超越此界限若有意外后果自负。

③at the risk of 冒……的危险

He saved my life at the risk of losing his own. 他冒着生命危险救了我的性命。

*好作文 www.haozuowen.net*二、bother 的名词用法:bother作名词讲时,主要有两个意思:一个是“麻烦”;另外一个是“烦恼”。

例句:It's no bother. What can I do for you?

不麻烦。我能为你做什么呢?

注意事项:

(1)在口语中说 don’t bother(…), 主要用于谢绝对方主动提出的善意帮助,一般翻译为“不用费心(……)了”“不用麻烦(……)了”。

(2) can’t be bothered (to do sth) 是一个惯用句式,翻译为“嫌麻烦而不做某事”“偷懒”。

bother的动词用法和名词用法就是这么多,同学们只要理解了例句,并且记住了例句,我想这个单词也就算掌握了。

risk作名词的意思: 篇七

危险,冒险;保险额;被保险人或物

risk的英语音标: 篇八

英 [risk] 美 [rɪsk]

so far用法归纳 篇九

1. 表示“到如此之距离”,可视为far的加强说明,此时可根据情况选用时态。如:

My feet are very sore from walking so far. 走了这么远的路,我的脚非常痛。

My mother lives so far away that we hardly ever see her. 我母亲住得那么远,我们很少见到她。

2. 表示“到如此之程度或范围”,根据情况选用适当时态。如:

I can only help him so far. 我只能帮他到这种程度。

Was it wise to push things so far? 把事情弄到这种地步明智吗?

3. 表示“到目前为止”“至今”(=until now),注意它所连用的时态:

(1) 若强调so far所描述的谓语动作一直持续到现在,则谓语动词用现在完成时。如:

So far there has been no bad news. 到现在为止还没有什么坏消息。

So far 50 people have died in the fighting. 到现在为止,已有50人在战斗中丧生。

有时还可修饰句中的非谓语动作,虽然此时的谓语不一定要使用现在完成时,但其中的非谓语动词通常可视一个完成时态简化而来的,如下面一句中的非谓语动词found可视为which have been found之省略:

It is one of the funniest things found on the Internet so far this year. 这是今年互联网上发现的最有意思的事情之一。

(2) 若不强调so far所描述的谓语动作一直持续到现在,则只是侧重描述一种客观现象,则可用一般现在时(谓语动词通常为某些状态动词)。如:

So far, it is only talk. 至今还只是空谈。

This is likely to be the biggest conference so far. 这很可能是迄今为止规模最大的一次会议了。

(3) 若so far并非描述谓语动作,而是间接地说明句中的某个名词,此时的句子谓语需要具体语境来使用时态。如:

She gave us a brief resume of the project so far. 她给了我们一份该项目迄今为止的历程简介。(句中的so far间接地修饰名词the project)

The new prime minister is facing his toughest political test so far. 新首相正面临迄今为止最为严峻的政治考验。(句中的so far间接地修饰名词his toughest political test)

(4) 有时用于省略句,句子时态被隐含在语境中。如:

So far, so good. 到目前为止,一切顺利。
