介詞的使用看你的基本功了,介詞一般根據(jù)意思來判斷,如in表示“在...里”,但有的介詞詞義較多,還有固定搭配,需點滴積累.
定語從句中“介詞+which”=where/when,在定語從句里作地點或時間狀語,介詞根據(jù)具體情況而變,其實是介詞提前.例如：
Do you still remember the time?We worked on the farm at that time合成定語從句
Do you stiill remember the time when (=at which) we worked on the farm?.
when/at which代替了at that time
Yesterday I visited the park.We planted many trees and flowers in the park last year
.合成定語從句為
Yesterday I visited the park where/in which we planted many trees and flowers last year.
where/in which 代替了in the park
