A. did he wake B. he wake C. he wakes D. he did wake
now 和 then 不是要全部倒装的吗?
原题目给的答案是A的,now,then,分别在句首时要全部倒装,如:Now comes the bus. Then came a noise like thunder.不知道now and then合在一起为什么又变成部分倒装了?

A. more and then = often 放在句首时要部分倒装。如:
Often have I told you to do your homework?

now and then 不时,做时间状语,放句首时不必倒装

d
do +动词 表示强调
而且后面用的是过去式,那么前后时态应该一致,所以还用过去式
