英语单选题

您好，请问下面这道题选什么？原因是什么？In my opinion, all Mr White _____good to his students in his class at present .He is very strict in this study.A,does does does B.does do do C.does does do D. did do does

选C.does does do.all Mr White does 指 all that Mr White does 怀特先生所做的一切.do good to 指:对...有好处. 如果要对一个动作进行强调,在这个动词前加do.do do good to 指确实对...有好处.而all Mr White does作为一个整体,后面谓语动词要用单数,所以是all Mr White does does do good to his students.(怀特先生所做的一切确实对他的学生有好处)do 在句中加强动词肯定的语气.eg: He does look tired.他确实显得很疲倦. She did write to say thank you. 她的确写信向你道谢了. Do shut up! 住口!

就是就是，听说过do-se-do， 但没听说过有 do do do 的用法

B all he does说的是一般现在时 ：助动词后面应该是用动词原形。do good to 是对 。。。。好：

选D,句子意思为"在我看来,怀特先生目前在他班上所做的一切都是对他的学生有好处的,在学习上他要求非常严格." all that did do 所做的一切,all that 做主语谓语动词要用单数第三人称形式,所以应该是does good to 固定搭配.对....有好处,有益,与之相反的词组为do harmful to ....对....有害.
