4. —Whose T-shirt is this?
—It can’t be John’s. It’s much too small for him.
句中的情态动词must, could, might和can’t分别表示不同程度的推测。现归纳如下： must用于肯定句中，表示说话人对事物的推测把握最大，意思是“一定；准是”。 如： (1) The photo must be Mary’s. Those are her parents.
(2) Alice has been in China for several years. She must be a big girl now.
◎may / might / could这三个词都可以表示说话人对事物的推测，但可能性较小，意思是“有可能；也许”。其中might / could比may较为委婉客气和更加不肯定。如： (1) My friend has lost his watch. This one may / might / could be his, but I’m not sure. (2) —Where is mom now? —I’m not sure. She may / might / could be in the kitchen. ◎can表示推测主要用于否定句和疑问句。can’t表示有把握的否定推测，意思是“不可能”。 如： (1) The hair band can’t be Jack’s. He is a boy. (2) —Look! Mr Hu is on the other side of the street. —It can’t be him. He has gone to Beijing. ◎must / may / could / might + be + doing sth. 表示“一定 / 可能正在做某事”，can’t / may not / could not / might not + be + doing sth.表示“一定不 / 不可能正在做某事”。must / may / could / might + have done sth.表示对过去或已经完成的事情的推测。如： (1) Peter must / may / might be playing football on the playground. (2) Maria must / may / might have gone to the movie. 【热身训练】 1. —Where is Tom? He hasn’t come to school today. —I think he _____be ill.
