____ you be able to travel at the speed of light,you would not reach that star in more than a thousand years.
A.Might B.Could C.Should D.Would
Why Meaning?
答
1. 答案：C.
2. 翻译：如果你(将来)能够以光速旅行，你在一千多年内也达到不了那个恒星。
3. 解释：
1）此题考查if引导条件状语从句的虚拟语气时，从句的倒装和省略用法。
2）如果是对将来动作的虚拟，if从句可以使用“should + 动词原形”，而主句使用“should/would/might/could + 动词原形”。
3）而if从句如果含有should的话，又可以直接将should提前，并去掉if.
即：If you should be able to travel at the speed of light
=Should you be able to travel at the speed of light
答
这是个虚拟语气，因为要达到光速是不可能的，should可提前，因为句子省略了if
