2017年成人学位英语考试重点短语语法精讲十三

1.as far as=so far as

就……而言,至于

【例句】As far as I am concerned, I'm not against your plan.

就我而言,我并不反对你的计划.

远到

【例句】He walked as far as the railway station yesterday evening. 昨天傍晚,他一直散步到火车站.

【总结】表示"直到……为止"之意时,as far as既可用于肯定句,也可用于否定句;在表示"直到……程度"之意的借喻说法中,as far as和so far as都可使用,但前者不及后者用得普遍.在表示"就……而论"之意时,as far as和so far as可互换使用.在表示"只要"、"尽……所能"之意时,应用as far as,不用so far as.

2.as if 似乎、好像

【例句】She treats himas if he were a stranger.

她待他如陌生人.

【总结】(一)as if 从句的作用.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.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.

(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.

(三)as if 从句的语气及时态 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.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:

a.如果从句表示与现在事实相反,谓语动词用一般过去时.如:ou look as if you didn't care. 你看上去好像并不在乎.

b.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.

c.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.

3.as long as=so long as

只要

【例句】As long as you don't betray me, I'll do whatever you ask me to (do).

只要你不出卖我,要我做什么我都愿意.

as long as: 和……一样长

【例句】This line is four times as long as that one.

这条线是那条线的四倍长.

【总结】?当用于同级比较时,as.....as 既可用于肯定中也可用于否定句中,

而so....as 只能用于否定句中.

His pencil is as long as mine.

His pencil isn't so/as long as mine.

当表示只要时,两者没有什么区别,可以替换.

e.g.Our profits will be good as/so long as the dollar remains strong.

【词语辨析】as long as ,as far as

as long as有"只要"的意思

As long as you keep working, you will get what you want.

as far as的意思比较抽象,可以表示距离上的"远到,直到"也有"据我所知"的意思,翻译起来可根据上下文语境灵活处理.

As far as I can see, it is a perfect plan.

在我看来,这是个完美的计划.

4.as well as

①和……一样

【例句】She as well as you is an English teacher.

她像你一样也是英文教师.

②与……一样好

【例句】He speaks Spanish as well as English. 他说西班牙语像说英语一样好.

【总结】A as well as B的结构里,语意的重点在A,不在B.成人英语三级考试
