<正> 介词+关系代词是定语从句中的一个难点,除了要根据先行词确定关系代词外,还要根据与定语从句中的动词或形容词或先行词的某种固定搭配决定选用哪个介词,如:The bird at which he was shooting flew away.(句中 shoot at 为固定搭配的动词词组,意为“瞄准”。)We are standing on the Great Wall,of which we’re proud.(句中 beproud of 为固定搭配的形容词词组,意为“引以为自豪”。)Do you notice the telescope through which we can see many stars far away.(句中 through 与先行词 telescope 搭配,意为“通过望远镜”。)
