Question

I hope that the little _____ I have been able to do does good to them all. A.which B.where C.when

I hope that the little _____ I have been able to do does good to them all.
A.which B.where C.when D.what
这里的little到底是名词还是形容词啊？I have been able to do是否为这个句子的插入语？这道题应该怎么做？（要有解题思路）
好吧我错了，其实是A.which B.what C.that D.when``````
打字的时候不小心把上一题的选项写上去了···

Answer 1

这里没有答案， 答案应该是 that, 先行词为the little.
little 在这里是不定代词，和all 等词一样， 被定语从句修饰时关系代词不能是which, 而应该是that
I hope （主句主谓语）that the little宾语从句主语）【that】I have been able to do（修饰主语little的定语从句） does（宾语从句的谓语） good to them all（从句双宾语）.

全句意为：
我希望我的微薄之力能对他们所有的带来好处

追问

如何判断是否句子的一个部分是否为插入语啊，比如我上面那句中的I have been able to do和He often helps the students who he thinks are not quick at their studies中的he thinks，为什么第一句不是插入语第二句是插入语啊？怎么区别？

追答

插入语是可要可不要的， 可是此句中that I have been able to do 如果没有， the little 就不知所云了。再说插入语也无需一个关系词来引导。
He, I think(插入语,前后要有逗号和句子隔开）， is an actor.

Answer 2

你好。最好的答案是 that. the little 已经是限定了，所以，如果有定语从句来修饰the little，应该用that而不是which来充当从句的宾语。 还有以下例子，一起记住吧：
the best THAT she can do
the worst day THAT we had there
the many people THAT she has met for today
the least possibility THAT there is of his survival in a bad car accident
the smallest house THAT we see here a family of ten lives in.

Answer 3

that
little在此是名词，that I have been able to do 是定语从句，修饰the little(指事物），而the little在从句中作宾语。
