Unit 49: A Terrific Teacher
第 49 課：一位超棒的老師
Andrew, I'm having a few problems with modal verbs.
Don't worry, Emily. They're a bit like...a jigsaw puzzle! It's simply a question of time. You can do anything if you put your mind to it.
Can you help me then?
No problem! We'll start with one of the most common verbs. The verb "can" expresses ability or permission. "I can play tennis," or "Can I go with you?"
And what about "may" and "could"?
Use "may" or "could" for permission. "May I come in?" or "Could I go with you?"
Right. Aren't "may" and "could" also used for possibility?
Yes. That's right. "It may rain." But for remote possibility, you could use "might." "It might also snow."
And what do I use for obligation?
You must use "must" or "have to." "I must catch my train," or "I have to catch my train."
Right. And what about "should"?
You should use "should" for giving advice and recommendations. "You should drink more water," and "You should try the new Chinese restaurant."
"Will" is for the future, isn't it?
Yes. "Will" is the best form of the future in all cases—even for the first person. "I will see you tomorrow."
And what about "shall"?
"Shall" is for making suggestions and offering help. "Shall we have a drink?" and "Shall I carry your bag?"
Oh, thank you, Andrew. This is a very interesting lesson. You are a terrific teacher! I'm going to make a frame for this lesson to keep forever. Can I also have a photo of you to put it in my frame?
Let me get the frame for you. Then I can dedicate it to you.
To my best student,
With love, from Andrew.
Oh, thank you, Andrew!
