2、要在句子后面加逗号，假如放在主句后则不用加。1.变疑问句将助动词移到句首.Hadshefinishedherhomework?2.变否认句在助动词后面加not.Shehadntfinishedherhomework.3.肯定回答及否认回答.Yes,shehad.No,shehadnt.4.特殊疑问句：Whathadshedone?构成：主语+助动词have,has+过去分词用法：1)表示过去发生的和如今有某种联络的动作，常和just,usually,already,since等时间副词连用Ihavejusthadlunch.(饱了，不用再吃了)Hehashadacupoftea.(不渴了，不用

3、再喝)Theyhavealreadyhadtheirholiday.(不能再度假了)Theboyhasalreadyreadthebook.(已经知道书的内容了，不用再看了)2)询问别人能否做过某事一般用如今完成时：Haveyoufinishedyourhomework?HaveyoubeentoBeijing?Haveheseenthefilm?3)表示开场于过去并持续到如今的动作IhavelivedinBeijingfortwentyyears.Ihaveworkedforthisschoolfor1year.4)表示一种经历，经历：去过地方，做过事情，经历过事情Ihaveneverhad
