Grammar explanation-语法解释
We can use modal verbs for deduction – guessing if something is true using the available information. The modal verb we choose shows how certain we are about the possibility. This page focuses on making deductions about the present or future. 我们可以使用情态动词进行演绎——利用现有信息猜测某件事是否属实。我们选择的情态动词表明我们对这种可能性有多么确定。本页重点是对现在或未来进行推论。
must-必须
We use must when we feel sure that something is true or it’s the only realistic possibility.当我们确信某件事是真实的或者它是唯一现实的可能性时，我们使用“must”。
This must be her house. I can see her car in the garage. 这一定是她的家。我可以在车库里看到她的车。
He must live near here because he always walks to work. 他一定住在这附近，因为他总是步行去上班。
Come inside and get warm. You must be freezing out there! 进来取暖吧。你在外面一定冻坏了！
might, may, could-可能、可能、可以
We use might, may or could to say that we think something is possible but we’re not sure. 我们用 might、may 或 could 来表示我们认为某件事是可能的，但我们不确定。
She’s not here yet. She might be stuck in traffic. 她还没来。她可能会遇到交通堵塞。
He’s not answering. He could be in class. 他没有回答。他可能正在上课。
We regret to inform you that some services may be delayed due to the bad weather. 我们很遗憾地通知您，由于恶劣天气，部分服务可能会延迟。
They all have the same meaning, but may is more formal than might and could.它们都有相同的含义，但“may”比“might”和“could”更正式。
can’t-不能
We use can’t when we feel sure that something is not possible.当我们确信某件事不可能时，我们使用can’t。
It can’t be far now. We’ve been driving for hours. 现在已经不远了。我们已经开了好几个小时的车了。
She can’t know about the complaint. She’s promoted him to team leader. 她不可能知道投诉的事。她已经把他提升为团队领导了。
It can’t be easy for him, looking after three kids on his own. 独自照顾三个孩子对他来说并不容易。
Note that these verbs, like all modal verbs, are followed by an infinitive without to.请注意，这些动词与所有情态动词一样，后面跟着不带 to 的不定式。
