His mother bought it for him yesterday.这件蓝色的毛衣是李明的，他的妈妈昨天给他买的。The boy belongs to the singing group of Grade One.这个男孩是一年级演唱队的队员。That new bike in the corner belongs to Helen.角落里那辆新自行车是海伦的。2.must(1)must为情态动词，无人称和数的变化，后接动词原形。注意在回答must引起的一般疑问句时，否定式常用neednt或dont have to，意为“没必要”，而mustnt表示“不准；禁止”。如：Must I finish the work on time？我必须按时完成工作吗？Yes, you must./No, you neednt/dont have to.是的，你必须。/不，你不必。（2）must表示推断，通常与be连用，意为“一定是；肯定是”。must这种表示推测的用法只用于肯定句中。如：There must be something wrong with the computer.那台电脑一定是出了什么毛病。注意：must表示肯定推测时，其否定形式是cant，意为“不可能”，表示有把握的否定推测。如：We must be wrong.我们一定是搞错了。（改为否定句） We cant be wrong.我们不可能搞错了。might或could表示肯定推测时，意为“也许是；可能是”，其否定形式是cant。如：The red pen cant be Lucys .It might/could be Lilys.这支红色的钢笔不可能是露西的，它可能是莉莉的。3.take part in, attend与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 3: Practice 1. 【问题探究】1.Mom , must I stay there the whole day?No, you C .You _ come back after lunch if you like.A. mustnt; can B. neednt; must C. neednt; may2.同义句转换：Whose pen is this?Whom does this pen belong to?3.I dont know what to do this afternoon.
