what do they usually do every day?what are they usually do every day?那句话是对的

问题描述:

what do they usually do every day?what are they usually do every day?那句话是对的

第一句为什么用do不用are 呢第一个do 是助动词,而are是实义动词,后面已经有一个实义动词的do了,就不要用are提问了。嘿嘿~~一句话中 不能出现两个 动词吗不能。除非是从句什么的,关键是这个动词的成分很重要,后面一个do是作谓语,那你前面提问用are是想做什么成分?
