【題目】—Excuse me, Mum. When can we have dinner?
—Not until it in half an hour.
A.will be prepared
B.is prepared
C.has prepared
D.was prepared

Answer 1

【答案】B
【解析】句意：—打擾了，媽媽。我們什么時(shí)候可以吃晚飯？—直到半小時(shí)后晚飯準(zhǔn)備好才可以。until引導(dǎo)的時(shí)間狀語從句用一般現(xiàn)在時(shí)態(tài)表示將來，只有B答案為一般現(xiàn)在時(shí)態(tài)，所以答案是B。
