　　Discovering useful structures
　　1. Lead-in
　　T: Look at the picture, the man is carrying a pile of books. So he can carry heavy books. He wants to enter the room, but he couldn’t open the door by himself. So he is making a request to ask for help from the woman by saying “Could you open the door, please?”
　　(The teacher writes the three sentences on the blackboard. 1.So he can carry heavy books. 2. He couldn’t open the door by himself. 3. Could you open the door, please?)
　　T: Look at the three modal verbs in each sentence and try to get their meanings.
　　S: The modal verbs “can” and “couldn’t” mean one’s ability to do something. They are similar to “be able to do something”.
　　S: “could” in the third sentence means making a request..
　　T: Well-done! These are the basic meanings of “can” and “could” , which are quite familiar to you. Of course, there’re other meanings of them. So today we’ll focus on the five pairs of modal verbs.
　　2.  Explanation of the use of modal verbs
　　1. can and could
　　4 表示能力（ability），指有能力做某事，意为“能够”。例如：
　　注意：表示现在，将来“能够”可用be able to 替换。表示过去“能够”并成功了只能用was/ were able to, 不能用could。例如
　　My grandma is over eighty, but she can/ is able to read without glasses.
　　We can/ will be able to talt the matter later.
　　I talked with her for a long time, and at last I was able to make her believe me.(不能用could)
　　5 表示请求（request）或允许（permission）。意为“可否”、“可以”。 Could 比can 更有礼貌，在此不是can的过去式。
　　Can you wait a moment please?
　　Liz, can you do me a favor?
　　Excuse me, could you tell me the way to the station?
　　I wonder if you could help me. (request)
