D
同位语从句,解释说明是什么样的evidence(证据)

答案是A。
首先排除B、C，how一般翻译怎么样，很显然，这里面和“怎么样”完全搭不上边；C的Whether经常和or连用，whether...or...有是否的意思，一般会二选一。
这里很容易 把A、D搞混，因为好像两个读上去都蛮通的，那来分析一下句子成分：

答案是A。
首先排除B、C，how一般翻译怎么样，很显然，这里面和“怎么样”完全搭不上边；C的Whether经常和or连用，whether...or...有是否的意思，一般会二选一。
这里很容易 把A、D搞混，因为好像两个读上去都蛮通的，那来分析一下句子成分：
Evidence has been found through years of study____ children's early sleeping problem likely to continue when they grow up.(这里我改了一下标点)
首先，Evidence has been found through years of study 这半句已经是完整的句子了，后面所有的都是用来修饰主语evidence的，（表示针对。。。的证据）所以，这是一句主语从句。而that除了在定语从句里是不能充当任何成分以外，在任何从句里都是要充当成分的，这里children's early sleeping problem likely to continue when they grow up.没有缺成分，因此，that是错的。
故选A。
可能比较深奥，如果还没弄懂，我再和你解释。

evidence②（that）①has been found through years of study _that_ ② children's early sleeping problem （这里应该有个is） likely to continue when ...

evidence②（that）①has been found through years of study _that_ ② children's early sleeping problem （这里应该有个is） likely to continue when ③they grow up
①是定语从句 先行词evidence 连词是that（这个that在句中充当宾语成分,所以可以省略）
②是同位语从句 that不能省
你漏打的is 是这个句子的动词
③是when引导的时间状语从句
