I hope that the little ____ I have been able to do has been of some use.
A.which B.that C.what D.for which
Which one?Why?

优质解答

B.that
I hope that后面是宾语从句（中间的东西下面讲）has been of some use.
the little（that） I have been able to do
我希望,我能够做到的那一点点,会有些用.
little ,only ,the one ,the only one ,first 等序数词.
有以上这些时,定语从句只用that ,不用which
