___There is going to be a policy change___of those things is going to change.A.Uless;few B...

答案：C.
翻译：如果没有一个政策变化,那些东西没有一样会变化.
1.few修饰的是可数名词,如果few of...做句子主语,则其谓语动词不可能用单三形式,由此可以排除AB.
如：Few of us (are) going to Beijing next week.
下个星期,我们中几乎没人会去北京.
2.unless = if...not...,意思是“如果不/除非”,引导条件状语从句.
则句子可以改写成：Unless there is going to be a policy change,none of those things is going to change.
= If there isn't going to be a policy change,none of those things is going to change.
如果没有一个政策变化,那些东西就没有一个会变化.
3.until则变化为：
Until there is going to be a policy change,none of those things is going to change.
= None of those things is going to change until there is going to be a policy change.
此句为隐形的not...until...句型,因为none隐含有not的含义.
翻译为：直到会有一个政策变化,那些东西才会变化.
4.此题只能说出的不好,其实CD都没有多大问题,而且此题的主从句时态都有误.
一般从句会使用一般现在时,而主句使用一般将来时.
