as引导方式状语从句,限制定语从句和非限制定语从句的区别是什么 1. 方式状语从句:方式状语从句通常由as, (just) as…so…, as if, as though引导。 1)as引导行为方式状语从句时,意为“如同……”､“按照……的方式(样子,办法)”｡这种从句常位于主句之后｡例如: You must try to hold the tool as I do. 你必须像我这样拿工具｡ Leave the things as they are. 别动这些东西｡ We must do as the Party tells us (to do). 我们必须按照党的指示办事｡ 2)(just) as…so…结构中位于句首，这时as从句带有比喻的含义，意思是"正如…"，"就像"，多用于正式文体. 例如： Always do to the others as you would be done by. 你希望人家怎样待你，你就要怎样待人。 As water is to fish, so air is to man. 我们离不开空气，犹如鱼儿离不开水。 Just as we sweep our rooms, so we should sweep backward ideas from our minds. 正如打扫房屋一样，我们也要扫除我们头脑中落后的东西。 2) as if/though引导的方式状语从句比较容易区分,这里不做解释. 2. as引导限制性定语从句时,构成“the same ... as ...”, “such ... as ...”, “as many (much, few, little) ... as ...”等结构｡ as可替代先行词,在从句中作主语､表语､宾语或状语｡ 例如: He isn’t the same person as he used to be. 他不再是过去那个样子了｡ I have never heard such a story as he is telling. 我从来没有听见过像他正在讲述的这种故事｡ Here is a bottle of pure water. You may use as much of it as you need. 这里有一瓶纯净水,你需要多少就用多少｡ This is the same watch as I have lost. 这块表和我丢失的那块表一样｡ In those days, many youths lived in the same way as the villagers did in the mountains. 那些日子里很多青年人跟山区的老百姓一样生活｡ 3. as引导的非限制性定语从句,可以修饰整个主句和主句中的一部分｡从句可位于主句之前､句中或主句之后,通常用逗号将其与主句隔开｡这时as可译为“正如”､“正像”｡例如: As is reported in the newspaper, talks between the two countries are making progress. 正如报纸上报道的那样,两国之间的会谈正取得进展｡ He is an Englishman, as I know from his accent. 从他的口音,我知道他是英国人｡ As was usual with him, he went out for a walk after dinner. 像往常那样,他吃完饭后就出去散步了｡ As is often the case, we have overfulfilled the production plan this year. 像往常一样,我们今年又超额完成了生产计划｡ This machine, as might be expected, has stopped operating. 正如人们所料,这台机器已停止转动了｡ He came very early this morning, as (was) usual. 像往常一样,他今天早上来得很早｡ 常见的这种定语从句还有: as has been said before(如前所述); as is mentioned above(如上面提到的); as may be imagined(正如可想象的那样); as is well known to us all(众所周知); as (sb) all know(众所周知); as often happens(正如经常发生的那样); as has already been pointed out(正如已经指出的那样); as we all can see(正像我们都能看到的那样)等｡ ■比较表 引导非限制性定语从句 引导方式状语从句 as关系代词 连词 的词性 从修饰整个主句或主句的某一部分。as 只修饰主句的谓语动词，表示“用什句 可在从句中作主语、表语、宾语等。某么方式或方法”，as只起引导词的功该从句常表达说话人对话语的态度。 作用，一般不在从句中充担成分。 能 及as 的作 用 位 从句可以置于主句之前，插入主句之从句一般应置于主句之后，有时也可置 中或置于主句之后。 置于主句之前。 其 从句位于主句之后时，as在有些情况从句中的as不能用which来替换。 它 下可以用which来替换。 ■指出下列as引导的从句是哪些从句： 1.He saw the girl, as he had hoped. 2.As you know, Anderson wrote a lot of fairy tales. 3.She cooks fish as my mother does. 4.The earth is round,as everybody can see. 5.As was natural,he married her. 6.John,as you know, writes plays. 7.We must do as the Party tells us to. 8.We should learn a foreign language as Marx did. 9.As you like maths,I like biology. （例3. 7. 8. 9. 为as引导的方式状语从句；其余为非限制性定语从句。） ③as if 与 as though引导的从句 请参阅上文所谈内容。 ④how引导的从句 有些时候，how引导的从句也可以表示一种方式，意为“以 …… 的方式，照 …… 的样子”。 You should behave how your father does. I have a right to do things how I please. ⑤according as引导的从句 according as也可以用来引导让步状语从句，意为“以 …… 的方式，按 ……”，注意：according to 只能构成介词短语，体现方式的含义，但不用来引导从句。 You may go or stay，according as you decide. You will be praised or blamed according as your work is good or bad. According as you behave yourself you will be well treated. 本文来源：https://www.wddqw.com/doc/294a3fc4905f804d2b160b4e767f5acfa0c78324.html
