Grammar fcus：Attributive clauses
1） 使用“介词+关系代词”引导定语从句的情况当关系代词在定语从句中作介词的宾语时，通常用“介词+关系代词”引导定语从句。如果关系代词在句中指人，则用“介词+ whm”；如果指物，则用“介词+ which”。例如:a. The man by whm the thief was caught was a gd pliceman. 那个抓住小偷的男人是个优秀的警察。b. This is the reasn fr which I was praised by my chemistry teacher. 这就是我得到化学老师表扬的原因。
2)介词选用的规则 介词的选择要根据其与先行词的关系以及句意决定，在定语从句中，经常可以根据谓语动词的搭配习惯来确定介词。
3)其他注意事项 含有介词的动词固定短语在定语从句中一般不拆开，在这种情况下，介词仍然放在后面，如hear frm, lk after等。而在介词处于句尾时，句中的关系代词可以省略。例如:
a.I met the child (whm) | lked after ten years ag. 我遇到了十年前我照料过的那个孩子。 b.I wanted t visit the huse (which) my grandparents Iived in. 我想去看看我祖父母曾经居住过的房子。
