Answer 1

C

【解析】

試題分析：句意:-你知道昨天8點(diǎn)的時(shí)候Millie和Andy在做什么嗎？-Millie看電視的時(shí)候，Andy去開門歡迎Tom。根據(jù)這個(gè)情景可知，這里表示的是過(guò)去一個(gè)時(shí)間，即昨天8點(diǎn)時(shí)正在發(fā)生的事情，as 引導(dǎo)的是一個(gè)時(shí)間狀語(yǔ)從句，所以第一空應(yīng)該用過(guò)去進(jìn)行時(shí)；第二個(gè)空的open是一個(gè)瞬間性動(dòng)詞，故用一般過(guò)去時(shí)態(tài)。故選C。

考點(diǎn)：考查動(dòng)詞時(shí)態(tài)。
