Step 2: Read and Practice
1. 总结may的用法,用may表示事情发生的_______________.
补充:还可以用__________表示事情发生的_______________.
may的用法:
a. 表示许可或征求对方的许可,有“可以”的意思。
e.g. You ______ go now. 你可以走了。________ I use your computer 我用一下你的电脑可以吗?
b. 回答以 may 开头的疑问句有如下表达法:
-May I smoke here 我可以在这儿抽烟吗?-Yes, you may. / Yes, please. 请抽吧。
-No, you can't. / No, you mustn't. / No, you'd better not. 请不要抽烟。
c. 表示猜测,通常只用于陈述句。
e.g. You may be right. 你可能是对的。
d. 在口语中 can 可以代替 may 表示许可,但 can 较随便,may 更正式。
e.g. Can I use your bike, John 约翰,我可以用一下你的自行车吗?
May I have a look at your license please, sir 先生,我可以看一下你的执照吗
2. 完成Part A练习。
Step 3: Presentation

2.When Xi Wang was six months old, what did she begin to eat
She began __________(eat) __________ when ……
3.What did Xi Wand learn to do when she was 20 months old

总结:当句子中已经有谓语动词, 而我们又要表达不止一个动作概念时, 其余的动词可以使用非谓语形式表达。动词不定式就是动词的一种非谓语形式, 其基本形式是“to+动词原形”。
注意:
动词不定式在句子中不作谓语, 因此没有人称、数和时态的变化。
动词不定式在句中常作谓语动词的宾语, 这一类谓语动词常见的有:
agree choose decide forget
hope learn like plan
prepare promise refuse remember
seem want wish would like
动词不定式的否定形式是“not to + 动词原形”。如:
You must promise not to be late again.
2. 小组合作找出哪些动词后可以接不定式做宾语,越多越好。检查预习作业。
3. 完成Part B部分。
Step 4:Presentation
补充学习动词不定式做宾语补足语的例子。
如:ask sb to do sth, invite sb to do sth
你能写出更多的这类固定搭配吗
