倒装结构

5-2:as置于句首

as若置于句首,则表示“因为”之意,为连接副词,等于because。

例:as he is nice, i like him.
= because he is nice, i like him.
(因为他人好,所以我喜欢他。)

as引导的从句,若为主语+一般动词的结构,且为肯定句时,有下列变化:

as he lives here, he may have ample chances to view the beautiful scenery.
---- living here as he does, he may...
(由于他住在这里,因此会有很多机会欣赏美丽的景色。)其步骤为:

第一步;将as句中的动词移至句首,变成现在分词;

第二步:再于主语之后按人称与时态的不同添加助动词do, does或 did。

例:as he works hard, he is sure to succeed.

(1)将works移至句首,改为现在分词working;

(2)由于works是第三人称单数现在时动词,故主语之后,应加does.

即成:working hard as he does, he is sure to succeed.
(由于他努力,因此一定会成功。)

*因此类变化较少见,通常不被使用,此处提出来仅供同学参考,不必模仿。
