您好，請問下面這道題選什么？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

選C.does does do.all Mr White does 指 all that Mr White does 懷特先生所做的一切.do good to 指:對...有好處. 如果要對一個動作進行強調,在這個動詞前加do.do do good to 指確實對...有好處.而all Mr White does作為一個整體,后面謂語動詞要用單數,所以是all Mr White does does do good to his students.(懷特先生所做的一切確實對他的學生有好處)do 在句中加強動詞肯定的語氣.eg: He does look tired.他確實顯得很疲倦. She did write to say thank you. 她的確寫信向你道謝了. Do shut up! 住口!

就是就是，聽說過do-se-do， 但沒聽說過有 do do do 的用法

B all he does說的是一般現在時 ：助動詞后面應該是用動詞原形。do good to 是對 。。。。好：

選D,句子意思為"在我看來,懷特先生目前在他班上所做的一切都是對他的學生有好處的,在學習上他要求非常嚴格." all that did do 所做的一切,all that 做主語謂語動詞要用單數第三人稱形式,所以應該是does good to 固定搭配.對....有好處,有益,與之相反的詞組為do harmful to ....對....有害.
