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. As to和As for的用法区别如下: 一、用法不同 1.As to 用法:表示涉及某点:as to常放于句中,表示“关于……方面”、“有关……之事”,但为了突出要提及的人或事之时,也可将as to置于句首,以示强调。但只涉及内容,而不涉及讲话人的态度。 2.As for 用法:as for可以用来表示讲话人对某人或某物持有“轻蔑”或“冷淡”的态度,甚至有憎恶之感,讲话时要重读引出的词语并在其后稍作停顿,以示强调,口气上带有嘲讽意味,译作汉语的“至于……嘛”。 二、含义不同 1.As to 释义:至于;关于。 2.As for 释义:至于,就……方面说。 三、侧重点不同 1.As to 解析:用以重提旧事:as to引出的内容都是前文曾经提到过的或者谈话对方都有所了解的,表示“说到”之义。 2.As for 解析:用以转换话题:在有前文的情况下as for总是出现在下文的句首,用来引出另外一方或者新的谈话内容,但与前文内容也有一定的联系,起到补充前文又突出后文的作用,使之与前文形成对照,译作“至于”。
as用作连词用法如下: 一、表示伴随 意为“随着”。如: As time passed, things seemed to get worse.随着时间的推移,情况似乎变得更糟了。 若其后不接从句,而接名词,则用介词with表示“随着”。如: With the development of modern agriculture and industry, more and more waste is produced.随着现代工农业的发展,污染越来越严重了。 二、表示让步 意为“虽然”“尽管”,要用于倒装句(相当于though,但语气稍弱)。如: Boy as he was, he behaved like a girl.他虽然是个男孩,但举止却像个女孩。 Much as I like you, I couldn’t live with you.我尽管很喜欢你,却不能和你一起生活。 Try as he would [might],he couldn’t open the door.他试过多次了,却仍打不开门。 三、表示时间 意为“当……时候”。如: He dropped the glass as he stood up.他站起来时,把杯子摔了。 As I was coming here, I met your brother.我来这里时碰到了你的弟弟。 注意,as引导时态状语从句时,其谓语动词通常只能是动作动词,而不能是静态或状态动词。如: 她出生后不久父母双亡,是由姑母抚养大的。 误:Her parents died as she was a baby and she was brought up by her aunt. 正:Her parents died when she was a baby and she was brought up by her aunt. 四、表示原因 引导原因状语从句时,其谓语动词可以是动作动词,也可以是状态动词。如: As you weren’t there I left a message.因为你不在那里,我留了个信儿。
