We use modal verbs to say how sure we are about something. 我们用情态动词去讲我们对一个事情有多确定。 1 must 1 必须，一定
We use must when we feel sure that something is true because there’s very strong evidence. 当有强有力的证据的时候，我们用must去表示我们觉得某件事是真的。 He must live near here because he comes to work on foot. We don’t know where he lives but we’re sure it’s not far away.Come inside and get warm – you must be freezing out there. You’re a zookeeper? That must be very interesting. Notice that must is followed by an infinitive without ‘to’. 注意must是跟着一个不带to的不定式的。 2 might, may, could 2 可能
We use might, may or could to say that we think something is possible but we’re not sure. 当我们觉得某事可能是真的，但是我们还不确定的时候，我们用might、may和could。 Did you hear that? I think there might be a burglar downstairs. She’s not sure there’s a burglar but she thinks it’s possible. We’ll try to get there early but we may arrive late if there’s a lot of traffic. Don’t put it up there. It could fall off and hit someone. Might, may and could are also followed by an infinitive without ‘to’. 这三个词同样跟着一个不带to的不定式 3 can’t 3 不可能
We use can’t when we feel sure something is not true. 当我们确信某事不是真的的时候，我们用can’t。 It can’t be a burglar. All the doors and windows are locked. He doesn’t know it’s not a burglar but he feels sure it’s not. It can’t be far away now. We’ve been driving for hours. Where’s the map? Really? He has to work on Christmas Day? He can’t feel very happy about that. Like the other verbs, can’t is followed by an infinitive without ‘to’. Can’t 跟上面提过的情态动词一样，也是跟着一个不带to的不定式。 Remember that all of these modal verbs– must, might, may, could and can’t have other uses. These are covered in another section. 记住，所有这些情态动词都有其他用法，在另外一节介绍里会提到。 |
