呃……小樹葉兒這回答我不敢茍同……
先翻譯一下：
1. We'll go to a place where my parents once lived.這里用where,為什么呢?因?yàn)楹竺嬷桓艘粋€(gè)live,無介詞.
我們說 live in a hotel,live in a resturant；而說live here,live there對(duì)不對(duì)?where和here\there的用法是一樣的,所以live 后面沒有介詞的時(shí)候前面就寫where.
2. We'll go to one place in which my parents once worked.如果溟鑾同學(xué)你看到前面有一個(gè)介詞in 或者在尾巴上有一個(gè)in,這個(gè)時(shí)候就用which.
其實(shí)不用管那么多語法概念的,看本題中這個(gè)動(dòng)詞是及物還是不及物動(dòng)詞,然后用這個(gè)動(dòng)詞造個(gè)短語,記得which只能指代一個(gè)物品一個(gè)名詞,比如love it,我們可以說love which；go to school就只能說成go to which,不能說 go which,這種情況下要么說to which 要么就用where.
呃……說了好多啊,但愿你能聽懂……
