情态动词形式

配规则

课”是客观要求,用have to,主语he为第三人称单数,故用has to.。
真题2(语法填空):
They_(finish)the project by next Friday,so theywork late this week.
答案:will finish;must
解析:第一空“by next Friday”(下周五前)表将来动作,用一般将来时will finish;第二空根据语

解题小妙招
情态动词推测妙招
情态动词表推测,时间语境是关键:
现在推测“must/cant+动原”,过去推测“have done”连:
肯定推测用“must”,否定推测“can't”先:
“since”“for”现完时,“by the time”过去完:
主动被动看关系,被动“be done”结构全。
