重点语法 行为动词的一般过去时及其回答。
重点句型 —Did you sing a song at the party? —Yes, I did/No, I didn’t.
I missed the chair and fell down. How could you lie to me?
Kangkang made a silent wish and them he blew the candles out in one breath.
重点讲解
1 Did Kangkang enjoy himself?康康玩得开心吗？
Enjoy是及物动词，后接名词，代词或是动名词，意为“喜爱，欣赏，享受……的乐趣。”
enjoy oneself = have a good/great time玩得愉快 enjoy doning sth. 喜欢做某事
巧辩异同 like, love与enjoy
(1)like喜欢（程度较弱）like doing/to do
(2) love热爱（程度较强）love doing/to do
(3)enjoy喜爱，欣赏，享受……的乐趣enjoy doing
2 It’s your turn.该你了。
turn 是名词，意思是“轮流”，It’s one’s turn to do sth.轮到某人做某事。还可以做连系动词，意为“变成……”，后接形容词做表语。
3 反身代词oneself变化如下：①第一二人称用形容词性物主代词+self(selves)
I→myself you→yourself(yourselves) ②第三人称用人称代词宾格+self(selves)
he→himself they→themselves
4 What happened to Michael at the party?聚会上迈克发生什么事情了？
happen to sb. 某人发生某事，to是介词 happen to do…碰巧干某事，to是不定式符号
