拓展阅读（课内同源 + 课外同源）

Passage1（课内同源：情态动词表推测）

　　We use modal verbs to talk about how sure we are about something. When we are almost sure, we use “must”. For example, “The site must be thousands of years old.” When we are not very sure, we use “may”, “might” or “could”. For example, “King Tut’s death could be related to an illness.” We can use “can’t” to say that something is impossible. For example, “It can’t be easy, but I’ll try my best!” For things in the past, we use “modal verb + have + past participle”. For example, “She must have been a rich lady” and “The Mayans must have built each pyramid on top of the other.” With these modal verbs, we can talk about ancient objects and people in an interesting way.
