第一题选D,将来完成时,表示在未来的那个时候（即你到纽约的时候）我已经动身前往伦敦了.
第二题选C,not until在句首要倒装,因为是this morning,时间在过去,所以助动词是did.
1.C 虚拟语气 省略 would
2.C 倒装句 原句是 he did not get up until 9 this morning
B;当你到达美国时,此刻我正在干....,用进行式
C;直到早上9点,他才起床.起床发生在过去了.
A 在你到达纽约的时候，我可能正赶赴伦敦。
C 是一个倒装句，
原句是：He did not get uo until 9 o'clock.
CC
A
等你到纽约时，我应该去往伦敦了。
时间状语用的是一般现在时，显然不是过去，是将来，所以主句用将来完成时，表示在将来某个时间将完成某个动作。
C
今早他直到9点才起床。
显然是过去时。Not until 引起了倒装。
