6、 你必需现在就干。（说话人认为必须现在干） I have to go now. （客观条件必须现在走） 5. need 的主要用法 1） need作情态动词，表“需要”，多用在否定式或疑问句中.

My father may be at home.（2）. maybe是副词

10、，相当于perhaps, probably, likely，常用于句首。Its eight oclock now. Maybe my father is at home. 11.had better 最好.had better do sth. / had better not do sth. （重点）You had better keep silent in class. 四、易错点：（一）、can, may, must , need, should的提问与应答：（1）.
