Answer 1

B 前一个句子有yesterday，所以用一般过去时。后一句用先在完成时，因为那个动作对现在有影响。
C当我正在工作的时候我不希望被打扰
D答案不肯定，可能是虚拟语气

A 句中有before，问在这之前有没有干某事。后一句表明已经看过了，用一般过去时
C现在完成时，体现的是一种到现在为止的一种状态，要用持续性动词

Answer 2

B
前面的有时间状语所以用一般过去时。后面没有，只是强调事情发生。
C
表示的是一个延续的状态
是不是应该是finifhes呢...应该是一般现在时
A
before提示现在完成时
C
three years提示延续性，所以是C

好像college前面只能是in吧...:)
