英语中do和be动词的提问有什么区别
do 和be都可以作实意动词和助动词。如果句子中的动词是实意动词,一般用助动词do进行提问,或者变为否定句。助动词do可以构成疑问句、否定句、倒装句、或者强调祈使句。系动词be后跟表语(形容词、作表语的副词、名词、代词、数词、介词短语、分词、不定式、动名词、表语从句等), 助动词be可以构成进行时,被动语态,there be 结构。如:
They work hard. Do they work hard? What do they learn? They don't work hard. Do be quiet! Never do they come late.
He is ill. He is a teacher. He is in the room. He is out. His job is to tend the woman. Five plus two is eight. He is excited. The news is exciting. He is killed. There is a pen on the desk. They are planting trees.
