1.If this dictionary is not yours,_D___can it be?
A.what else B.who else C.which else D.who else's
whose else=who else's吗？

相同。前者是英式用法，后者是美式用法。
这里要选所有格，直接排除ABC。

2.It's no____arguing with Bill because he will never change his mind.
A.use B.help C.time D.way

A.
It's no use doing 固定搭配，做某事没用。其他选项都没有相应搭配。
和Bill争吵是没用的，因为他不会改变心意。

3.Come and see me in____.(C)
—With pleasure.That's what I'm expecting.
A.two or three days' B.two or three day's time C.two or three days' time D.two and three days

A末尾有一撇，相当于一个复合形容词，是作定语的，排除。
B three后面不能加day，要加复数，排除。
D and没有意义，两天或三天，用or。
