Question

______, I think, and the problem could be settled soon.

A.So long as you keep spirits
B.If you double your efforts
C.Making great efforts
D.A bit more efforts
答案选D，原因是什么？

Answer 1

选D.比较接近口语

A.So long as you keep spirits
B.If you double your efforts
都是引导条件句的，

因为有了and，所以不可能是从句

Making great efforts 是非谓语，就算没有and,这样的表达也不对。现在有

and，更不可能了。

根据排除法选D

A bit more efforts 这里是祈使句，“只要再多一点努力”

and这里是并列连词，用来连接另一句句子the problem could be settled soon

Answer 2

选A。翻译出来的话就是‘只要你充满勇气，我想，问题很快就会被解决的。’
