课堂探究

1. -Jenny, can you come to my part yon Saturday afternoon?

-珍妮，星期六下午你能来参加我的聚会吗?

-Sure，1'd love to. -当然可以，我很愿意。

(1)句式Can you do......？可用来客气地邀请某人做某事，can可以用could来替换。

否定回答通常用I‟m sorry, I can't/I'd love/like to，but...

即学即练一

( )1. -Can you stay here for dinner?

-Sorry, I______. I have something important to do.

A. don't

B. didn't

C. needn't

D. can't

( )2. -_____ you play tennis with me tomorrow

-Sure, I'd love to.

A. Can

B. Should

C. Need

D. Must

2. I have to help my parents. 我必须帮助我的父母。

（1）have to意为“必须，不得不”，后跟动词原形，其第三人称单数为has to。

例如：She has to look after her mother. 她必须照顾她妈妈。

（2）help为动词，意为“帮助”。help sb. (to) do sth.帮助某人做某事。

例如：could help me (to) carry these boxes? 你能帮我搬这些箱子吗？

have to与must含义均为“必须”，且都接动词原形。不同之处在于have to表“不得已而为之”，must表责任义务所在。have to有人称、有时态变化（has to/had to/will have to）,must 为情态动词，无人称、时态变化。have to的否定或疑问借助助动词do/does/did等；must的否定为Must…？问句否定答语为needn‟t；not have to=needn‟t，must 表示确切判断“一定”，反义词为can‟t“不可能；一定不”

4. Thanks for asking.谢谢您的邀请。

Thanks for…表示“因什么而感谢某人”，介词for后可接名词、代词或动名词，相当于thank you for…。

thank 的其他短语

thanks to意为“幸亏；由于”，头是介词，后面接名词、代词或动名词。

例如：Thanks to a lot of hard work, it was all a great success.

由于尽心竭力，这件事取得了巨大的成功。
