高分请教英语语法！高手请进~

问题有点多，但是时间紧迫~~回答得好的再加分！
《复合句》
定语从句：
1）
do you remember tha day when he came to see you?
do you remember tha day (that)we spent in the woods?
2）
this is the house where he lived last year.
this is the house (which) he visited last year.
3）
i know the reason why hee did so.
i know the reason (that) he explained at the meeting.
这几句定语从句我是怎么也弄不明白。比如第一句，书上是说：要看先行词在句中是起副词作用作时间状语，还是起代词作用作宾语。我实在搞不拎清~~到底要怎么分析呢？
