Need I to do exercise two hours every day?还是Do I need toexercise two hours every day?

问题描述:

Need I to do exercise two hours every day?还是Do I need toexercise two hours every day?

need 既可作情态动词 后跟动词原形,也可作实义动词后跟to do.
前一句把to去掉就是对的,后一句应该为Do I need to do exercise two hours every day?才是对的

是Do I need toexercise two hours every day?
