　　注意：先行詞是表示地點(diǎn)或時(shí)間時(shí)，有時(shí)用where或when，有時(shí)用that(which)引導(dǎo)定語(yǔ)從句，這時(shí)要根據(jù)從句的謂語(yǔ)動(dòng)詞是及物的還是不及物的。如果是及物的就用that(which)，否則用where或when。例如：

　　This is the house that(which)he visited last year.

　　I thought of the happy days when I stayed in Beijing.

　　I have never forgotten the day which we spent together.
