Yes, he does. No, he doesn't What does he do for us? He works for us.一般过去时 be动词+行为动词的过去式 否定句式:在行为动词前加didn‘t,同时还原行为动词,或was/were+not; was或were放于句首;用助动词do的过去式did提问,同时还原行为动词 例如: Did he work for us? He didn't work for us. He worked for us.一般将来时 am/are/is+going to+do 或 will/shall+do am/is/are/about to + do am/is/are to + do; 一般将来时的表达方法 be going to +动词原形 be +不定式,be to+动词原形,be about to +动词原形 be able to +不定式 be about to+动词原形 will + 动词原形; 例如:He is going to work for us.
