15、 know. 我住得离工作单位很远，这你是知道的。2.只有as的情况：以下两种情况，习惯只用as，不用which。在such,as, the same后引导定语从句时只能用ash。如：I never heard such stories as he tells.我从未听过他讲那样的故事。Its the same story as I heard yesterday. 这故事跟我昨天听到的一样。This is the photo which shows my house. 这张照片拍的是我的住宅。 当从句位于主句前面时，只用as。如：As is known to everybody, the m
16、oon travels round the earth once every month.月球每月绕地球转一周，这是每个人都清楚的。3.值得注意的情况：以下三种情况值得注意。as 引导的非限制性定语从句应与主句在意义上和谐一致，但which无此限制。比较：He went abroad, as which was expected.他出国了，这是大家预料到的。He went abroad. which was unexpected.他出国了，这让大家感到很意外。（不用as)2as 引与非限制性定语从句时，先行词通常不能是主句中某个具体的词，而应是整个句子、整个短语或某个短语推断出来的概念，而wh
17、ich则无此限制。如：The river which flows through London,is called the Thames.这条流经伦敦的河叫泰晤士河。（不用as)(3）当as 引导非限制性定语从句作主语时，其谓语通常应是连系动词，而不宜是其他动词，而 which则无此限制：She has married again, as which seemed natural.她又结婚了，这似乎很自常。She has married again. which delighted us.她又结婚了，这使我们很高兴。（不用as)关系代词who与whom的区别两者均只用于人，从理论上说，who
18、为主格，whom为宾格，但实际上，除非在正式文体中，宾格关系代词whom 往往省略不用，或用who或that代之。如：The man(that.who. whom) you met just now is called Jim.你刚遇见的那个人叫吉姆。不过，值得注意的是，直接跟在介词后面作宾语时，只能用whom，而且不能省略。如：She brought with her three friends. none of whom I had ever met before. 她带了3个朋友来，我以前都没见过。另外，引导非限制性定语从句目作宣语时，who 和whom均可用，但以用 whom 为佳，此时也不能省略。如：This is Jack, who whom you havent met before. 这是杰克，你以前没见过。学科网（北京）股份有限公司
