I won't tell the student the answer until he_A__on it for more than an hour.

B.will have worked

為什么選哪兩個(gè),還有說明一下until,not until 的題,前后時(shí)態(tài)怎么想
不好意思，第一題C就是you'll find
midnight13說得已經(jīng)比較明白了，
是說主從句要現(xiàn)在時(shí)都現(xiàn)在時(shí)，要過去時(shí)都過去是么
還有“will后面不能加過去時(shí)態(tài)的”應(yīng)該不對。will have worked是將來完成時(shí)，will have been working是將來完成進(jìn)行時(shí)
