Do you remember the days when we chatted with each other all night? 2. Do you remember the days that/which we spent studying together in the classroom? 3. I don't know the reason why he didn't turn to his good friend for help yesterday. 4. We won't accept the reason that/which you have given. 5. Can you recognize the house where you used to live with your parents? 6.Can you recognise the house that/which Tom sold three years ago? 注意辨析 表示时间、地点及原因的名词作先行词时，从句的引导词用关系代词还是关系副词可以用以下方法判断： ①把先行词代入宾语从句中，若作主语或宾语用关系代词；作状语则用关系副词； ②定语从句中的谓语动词是及物动词，后面无宾语，用关系代词；是不及物代词则用关系副词。 1. Is this the place ______ you were born? A
