9 . Can you ask … to ring me back , please ? 10 . I\'ll ask … to call you .

Ⅲ . 语法学习

情态动词 must , may , might , can\'t , could …

这些情态动词常用来表示推测。

1 . must 用于肯定句，作“准是；一定是；一定是；相必是”解，对当前发生的情况作出非常肯定的推测。

must 用来表示有把握的肯定推测， ( 否定推测用 can\'t , 不能用 mustn\'t ) 其推测原因往往是根据某项客观存在的条件产生的。

The man talking to the students in the classroom must be a teacher .

2 . can\'t 或 couldn\'t 作“不可能，想必不会”解，以对当前发生的事作出否定的推测，表示出惊异，怀疑的情绪。

He can\'t be waiting for us at the school gate since he is ill .

3 . might , may , could 用于肯定，但它表示一种不太肯定的说法。译成“也许；可能”。这几个词同 must 相比，表示“无客观条件线索”的推测。

She might ( may , could ) be in the classroom .

这里值得注意的是 be supposed to… , 常常表示“应该……”。

3 . 与 so , not 连用。

— Will she come with us ?
