7、o Li knows well, is our group leader. 王欣是我們的組長，小李對他很了解。（該句中whom不可省略，亦不可為that取代）which和as引導(dǎo)的非限制性定語從句可修飾整個(gè)主句或主句的一部分，as從句還可置于主句之前。例如：He has to work on Sundays, which he doesnt like.他星期天得工作，這是他不喜歡的。As you know, the work is very difficult.你們知道，這項(xiàng)工作很難。which和whom在引導(dǎo)非限制性定語從句時(shí)常和of或其他介詞連用。例如：The buses, most of
