問題1是對的
問題2的句子一是對的.句子二why不能等于什么了吧.
后面的看不懂了,你想表達(dá)什么?
沒有at the day,只有at that moment就是的確是which等關(guān)系代詞前的介詞以先行詞前所需加的介詞決定的是對的？我的意思是： The reason why he was fired was not clear 的why 能不能用for that 代替？就是我不知道是the reason for 還是the reason of因為不收說that前的介詞以先行詞前所需加的介詞決定的嘛 那么就是加of 還是加for 的問題了 你確定我的問題1里說的對嗎which等關(guān)系代詞前的介詞以先行詞前所需加的介詞決定的不能用for that或 the reason of代替那定語從句的why 不能像where when一樣被替代嗎？Don't forget the day when you were received into the Youth League中的when 是不是也能用on which代替呀？回答下Don't forget the day when you were received into the Youth League可以還原成不是從句的狀態(tài)， you were received into the Youth League on that day ,don't forget it。......因為on that day 可以用on which 或when 代替，所以該情況成立那reason可以換成 for which 吧？另一邊我提問說可以換成for which 但就是沒有for that 是嗎
