7、e_some_pocket_money_left*have sth.left 意为“有留下/剩下”是 “have sth.过去分词” 的结构，表示宾语是宾语补足语动作的承受者，即宾语与其后的过去分词在逻辑上是动宾关系。The man had his arm hurt.*“havesth.to do”表示“有(应做的事)要做” 。 Andy has a lot of work to do every day.*“havesb.不带 to 的动词不定式” 表示“要求/命令/安排某人做某事” 。如：I will have my brother repair my computer.2and abou

11、(主语)谓语动词动作的承受者(宾语)被动语态：动作的承受者(主语)be动词的过去分词by动作的执行者*被动语态强调动作承受者，被动语态的基本形式为：系动词 be及物动词的过去分词。被动语态的不同时态是通过系动词 be 的时态变化来体现的，其人称和数应与主语保持一致。3*掌握主动语态与被动语态的相互转换：一般现在时的被动语态：am/is/are done如：We clean the classroom every day.The classroom is cleaned(by us)every day.一般过去时的被动语态：was/were done She hurt me.I was hurt
12、 by her.*注意被动语态的几个特殊情况：(1)带双宾语的两种被动语态形式：如：She gave me a book. I was given a book by her./A book was given to me by her.(2)感官动词和实义动词如 make，see，feel 等后所省略的动词不定式 to 需被还原。如：My teacher made me do my homework. I was made to do my homework by my teacher.(3)有些动词(如：happen，appear，come out，sell well)和动词短语(如：take place)是没有被动语态的。
