为什么选这个答案？请教高手。

Question

It ___ as if they could see and hear us in action.
A. was
B. were
C. should be
D. will be
正确答案是D，为什么用这种时态？
原句是：They will be able to see and hear us in action.
O(∩_∩)O谢谢

Answer 1

原句：They will be able to see and hear us in action.
我们的一举一动他们都将能够看到和听到。

原句用的是将来时，所以也用将来时。

It will be as if they could see and hear us in action.
我们的一举一动他们好像/貌似都将能够看到和听到。

Answer 2

这个主要是根据上下文选择。原句想必不难理解，一般将来时态。
题目中as if是一个虚拟语气，后面的从句用一般过去时，翻译成“貌似”比较恰当，因为不是真的。比如
You are acting as if I owned you one.
你现在的表现好像我欠你情似的（实际不欠）。
