Did you go to their wedding?No, I had not been invited. Did they have a big wedding?The window is dirty.I know. It has not been cleaned for weeks.（2） 需要强调或突出动作的承受者或时间本身。如： All the employees except the manager are encouraged to work online at home.（3） 在文章标题、广告、新闻中。如：Girls wanted.招女工。Millions of pounds worth of damage has been caused by a storm which swept across the north of England last night.（4） 当动作的执行者不是人时。如：The number of deaths from heart disease will be reduced greatly if people are persuaded to eat more fruit and vegetables.3. 注意短语动词和含有情态动词的被动语态（1） 在被动结构中，切不可丢掉动词后面的介词或副词。 如：That old man was often laughed at.那位老人常被人嘲笑。The plan will be given up. 那个计划将要被放弃了。Bad habits have been done away with.坏习惯已经改掉了。（2） 含有情态动词的句子的被动语态结构是：情态动词 + be + 动词的过去分词。如：The plan ought to be put into practice as soon as possible.计划必须尽早执行。4. get + 动词的过去分词可以表示被动，此结构比较口语化，如：She got married last week. 她上周结婚了。He fell off the car and got killed.他从车上摔下来，摔死了。易错知识总结（一） 一般过去时和现在完成时的用法区别1. 一般过去时所表达的一个或一段过去时间是可以具体确定的，与其他时间没有牵连。它所表示的事情纯属过去，与现在情况没有联系。现在完成时表示的事情发生在不能具体指出的过去某个或某段时间。它所表示的事情与现在情况有关系，是过去的事情在现在产生的结果或对现在的影响。2. 比较下面几组句子，体会两种时态的不同：（二） 一般过去时和过去完成时的用法区别1. 一般过去时是相对现在说话时刻而言的，过去完成时则是相对过去某一时刻而言。两种时态建立的时间参照点不同，对过去完成时来说，这个时间参照点十分重要，她是过去完成概念赖以简历的基础，也是和一般过去时相区别的重要标准。2. 过去完成时的时间状语常用by和before引导的短语表示，如by that time, by the end of,before 2000,by the time+句子等。（三） 过去完成时与现在完成时的用法区别1. 两种时态都常与表示一段时间的状语连用，但现在完成时表示的是延续到现在或同现在有关的动作（剧中不可有表示过去特定时间的状语），而过去完成时表示的是在过去某时之前已经完成或延续到过去某时的动作（句中有表示过去特定时间的状语）。2. 比较下面的说法（四） 主动形式表被动意义1. 系动词look，sound，feel，smell，taste，appear，seem，go，prove，turn，stay，become，fall，get，grow，keep + 形容词/名词构成系表结构。如：The steel feels cold.His plan proved（to be）practical.It has gone bad.2. 表示开始、结束、运动的动词，如begin，finish，start，open，close，stop，end，shut，run，move等。如：Work began at 7 oclock this morning。The shop closes at 6 p.m. every day。3. 表示主语的某种属性特征的动词，如read，write，act，iron，cut，draw，drive，sell，wash，clean，wear，open，cook，lock，shut，dry，eat，drink。这类动词一般不单独使用，常有一个修饰语。如：This coat dries easily。这种外衣容易干。Nylon cleans easily。尼龙容易洗干净。Food can keep fresh in a fridge。食物在冰箱里能保鲜。Your speech reads well。你的演说讲得很好。This material has worn thin。这个材料已经磨薄了。The match wont catch。火柴擦不着。The plan worked out wonderfully。这计划制定的很好。The engine wont start。引擎发动不起来。4. 少数动词用于进行时，其主动形式表示被动含义，如print，cook，fry，hang，build，make。如：The books are printing。这本书正在排印中。The meat is cooking。肉在煮。5. 介词in ，on under等 + 名词构成介词短语表被动意义表示方位的介词与含动作意义的名词合用，含被动之意，其意义相当于该名词相应动词的被动形式，名词前一般不用冠词。常见的有：under control（受控制）；under treatment（在治疗中）；under repair（在修理中）；under discussion（在讨论中）；under construction（在施工中）；beyond belief（令人难以置信）；beyond ones reach（鞭长莫及）；beyond ones control（无法控制）；beyond our hope（我们始料不及）；for sale（出售）；for rent（出租）；in print（在印刷中）；in sight（在视野范围内）；on sale（出售）；on show（展出）；on trial（受审）；out of control（控制不了）；out of sight（超出视线之外）；out of ones reach（够不着）；out of fashion（不流行）。如：The rumor is beyond belief（=cant be believed）。His honest character is above all praise。（=His honest character cannot be praised enough。）Today some treasures are on show（=are being shown）in the museum。6. 不能用于被动语态的及物动词或动词短语：fit，have，wish，cost，agree with，arrive at/in，shake hands with，succeed in，suffer from，happen to，take part in，walk into，belong to等。如：This key just fits the lock。Your story agrees with what has already been heard。
