I attended a concert yesterday so it might still be in the music hall.我不记得了！昨天我参加了一场音乐会，所以我可能把它放在音乐厅了。take part in, attend, join这组词都有“参加，加入”的意思，其区别是：take part in 侧重参加某项群众性、集体性的事业、工作或活动，突出参加者在其中发挥一定的作用。attend 侧重参加或出席会议或学术活动等。join 普通用词，指加入党派、团体或游戏活动等。如：We all attended the meeting.我们全体都参加了会议。If you join the club, you have to obey its rules.如果你参加俱乐部，你就得遵守它的规章。Step 2 小结训练(A)1.Diaoyu Islands _China ever since ancient times.A.belong toB.is belong inC.is belonging to(B)2.Students in our school know _shouting is not allowed in the library.A.can B.must C.may(A)3.Whats wrong with Mary?She was ill,she didnt _the meeting and she wont _the activities tomorrow.A.attend;take part inB.attend;joinC.take part in;attend(B)4.The boy must be Li Wen.I think it_ .Li Wen is ill at home.A.mustnt B.cant C.neednt环节说明：学生进一步巩固对单词attend,must 等的理解和掌握。Step 3 问题探究1.Mom,must I stay there the whole day?No,you _.You _come back after lunch,if you like.A.mustnt; canB.neednt; mustC.neednt; may【解析】答案是C。注意mustnt 是不准的意思，neednt 是不必的意思。2.同义句转换：Whose pen is this?_【解析】答案是Who does this pen belong to?或者Whose is this pen?3.同义句转换：J.K.Rowling is her favorite writer._【解析】答案是She likes the writer J.K.Rowling best或者Her favorite writer is J.K.Rowling。4.Whats wrong_ him?Something terrible happened_ him.A.with；with B.with；
