选择题
In my opinion, all Mr Li ______ good to his students in his class at present. He is very strict with them in their studies.
A．does does does
B．does does do
C．does do did
D．did do does
答案
答案：B
题目分析：考查定语从句和强调句型。All是先行词，all后面省略了that，that作为does的宾语。第一个does是定语从句的谓语动词。第二个does表示强调，强调do。句意：在我看来，李先生坐的所有事情的确对他班里的学生有好处，在学习方面对学生很严格。故B正确。
点评：定语从句的考查关键在于句子成分的分析，强调句型的关键在于被强调成分的认定。
