回答：1.  不知道对方是否在伦敦，是“过去”不知，所以用过去时。
2.  同上，我的“想”是过去的，后面的过去将来时刚好和它在时态上配合，即“一般过去时+过去将来时”。
3.  until引导的时间状语从句用一般现在时，表示“在......之前”，主句要用一般将来时与之配合。
4.  时态上配合，即“一般过去时+过去将来时”。
5.  句子后半句意思是“我听不清发言人正在说什么”，显然该用现在进行时。
6.  “误车”一事是现在说出来，但是还没有成为事实，所以that引导的补语从句用一般将来时就可以了，表示误车的可能性较大。
7.  “系动词be+动词不定式”具有表示将来动作的含义，关键要看be的词形，如果是am，is或者are，表示一般将来的语法范畴，反之如果是was或者were，则表示过去将来。
