1.C
倒一下就简单了：Nothing can be done until she returns.
not...until..句型,nothing隐含了not.
翻译：知道她回来,才能采取点措施.（她不回来就无计可施.）
____ she returns nothing can be done.
A.Till B.That C.Until D.Whether
2.C
只有C who才能引导这个宾语从句,代指人并做该从句的主语.
Do you know ____will be our class teather?
A.whom B.that C.who D.which
3.A
你是被你老师问问题,对不对?所以此题该填入被动语态并做从句的谓语,前面有个didn't,所以时态是一般过去时.
Why didn't you answer the teather's question when you _____in class,David?
A.were asked B.asked C.are asked D.ask
5.（Unluckily）he did not get the job.(luck)
unluckily adv.不幸地,做句子状语.
6.The other students in my class often ask me (to assist) them.
ask sb to do sth 要求某人做某事
7.Julia works as an English teather in the school.(保持原句意思)
