19、kly as I could and left in a hurry.()dress改为dressed8.谓语动词的主动形式表示被动意义(1)英语中有很多动词,如sell,wash,open,lock,read,write等,当它们被用作不及物动词来描述主语特征时,常用其主动形式表达被动意义,主语通常是物。这时常与副词easily,well等连用。*The pen writes smoothly.这钢笔书写流利。*His new novel sells well.他的新小说很畅销。(2)表示“发生、进行”等的不及物动词和短语,如happen,last,take place,break out,

21、义相当于动词不定式的被动形式。*The house needs repairing(to be repaired).这房子需要修理。【即学活用】(1)语法填空。All the tickets _(sell)out when they arrived.(2)My T-shirt _and my trousers dont need _so I hardly need to do some washing today.我的T恤衫很好洗,我的裤子不需要洗,所以我今天几乎不需要洗衣服。soldwashes wellwashing/to be washed二、by+v.-ing的用法by+v.-ing意
