知识梳理
Language points
1．invite 动词，意为“邀请”；其名词形式是invitation。
常用短语：①invite sb.to＋地点，意为“邀请某人到某地”。
②invite sb.to do sth.意为“邀请某人做某事”。

在七年级下册第一单元我们已经学了情态动词can的相关用法，本单元主要学习情态动词can引导的一般疑问句及其回答。
1．can引导的一般疑问句需将can放在主语之前。
2．can表示“做某事的能力”，意为“能；会”，对以它开头的一般疑问句作肯定回答用“Yes，主语＋can.”，作否定回答用“No，主语＋can't.”。
eg：—Can you sing in English？你会用英语唱歌吗？
—Yes，I can./No，I can't.是的，我会。/不，我不会。
can 引导的一般疑问句
3. can与第二人称连用，常用于熟人之间表示邀请或
请求,即Can you...
①接受请求或邀请时, 常用Sure, I'd love to./OK，that sounds great./Certainly./Of course.等回答。
②拒绝邀请,一般不直接说No, 而应说(I'm)Sorry, I can't.以示礼貌，然后说明理由；也可用I'd love/like to, but...委婉地说明不能接受的原因并表示歉意。
【注意】发出邀请或请求时,也常用could使语气更委婉、客气。
【拓展】can还可以表示推测,常用于否定句。
eg：That man can't be Mr. Liu because he is in London now.
那个男人不可能是刘先生，因为他现在在伦敦。
