希望能够帮到楼主

Answer 2

1C: the action (move) is done before the action (live), therefore past perfect tense should be used.
2A: It's a positive answer that you go to bed, but 'did go' is used instead of 'went' because it wants to stress on the waiting time that I had been waiting for him very long.

Answer 3

1，A since 后面要跟过去时，"自从……"。此句的意思：自从他们去了中国，他们就一直住在上海。
2.B not ... until是固定搭配。再加上我没有睡觉是过去发生的动作，所以用过去时。此句意思：你等了他很久吗？是的，我一直到五点才睡。
希望能帮到你。
