第一句是正確的：一周前我搬家了.
第二句是錯(cuò)誤的,由于move是瞬間動(dòng)詞,不能和時(shí)間段連用,所以改為：I have been in the new house for a week.我已經(jīng)在新家住一個(gè)星期了.（說明你已經(jīng)搬家一星期了）如果想強(qiáng)調(diào)搬家呢，i was ??? moved???不行噢，如上所說，moved瞬間動(dòng)詞，不能和時(shí)間段 for a week 連用?；蛘吣憧梢赃@樣表達(dá) I have been busy moving into a new house for a week. 我忙了一周在搬新家。表示“狀態(tài)”才能夠和時(shí)間段連用。
