使用被动语态应注意的问题

1.当句子的主语是动作的执行者时,谓语动词用主动语态;当句子的主语是动作的承受者时,谓语动词要用被动语态。被动语态由“助动词be+动词的过去分词”构成,动词的时态通过助动词be的形式变化表现出来。例如:1)一般现在时:Y ou are required to do this.2)一般过去时:The story w as told by her.3)一般将来时:The problem w illbe discussed tom orrow.4)现在进行时:The question is being discussed in the m eeting room.5)过去进行时:The new road was being m ade.6)现在完成时:The novelhas been read.7)过去完成时:H e said thatth…

点击现在进行时

As引导的时间状语从句的用法

As作连词引导时间状语从句时,着重强调主句和从句中的动作同时发生,并且从句通常放在主句之前。归纳起来有下列两种情况: 1)状语从句的谓语动词是持续性动词,从句时态常用进行时态。如: As he Was waiting,he suddenly heard a voice from above…… (JB,Ⅳ.L3) As Bethune and the other doctors were climbing the hills,they could see the enemy entering the village in the valley below.(JB,Ⅴ.L10) 2)状语从句的谓语动词是终止性动词,从句时态常用一般时态。如: As she stood there,she heard the first bell.(JB,Ⅴ.L4) As they looked up,they saw another cloud coming towards them.(JB,Ⅴ.L5) As they watched.it came nearer and nearer.     

说说系动词

系动词本身有一定的意义,但其后必须加上名词、形容词或动词的-ing形式,构成名词性复合谓语。英语里系动词很多,但be是最常见的系动词。例如:I am a student.(名词作表语)H e is very young.(形容词作表语)She w as here yesterday.(副词作表语)The news is exciting.(动词的-ing形式作表语)The fog is gone.(过去分词作表语)英语中除了be以外,还有其他的系动词。归纳起来,这些系动词可以分为两大类:一、表示“变化”的系动词有:1.becom e意为“变成”、“成为”。例如:Itbecom es m uch warm er.天气变得暖多了。Later she becam e a fa…

高考中英语学科的错误大致可分为语法错误、词汇错误和上下文关系错误,在近几年高考英语改错中,这三类错误涉及以下几个方面:1.主谓一致方面的错误改错行中出现谓语动词时,就要找出它的主语,看看句子的主语和谓语在人称和单复数上是否一致。这方面的问题是改错中最为常见的。①N ow m y picture and the price is hanging in thelibrary.(2000.9题)应把is改为are。②B ut one and a half year later,I now thinkE nglish is fun to learn.(2005.4题)应把year改为years。③Their w ord w ere a greatencouragem entto m e.(2003.10题)应把w…

倒装句大盘点

在英语句子中,主语在前、谓语动词在后的句子叫陈述句;谓语动词在前,主语在后的句子叫倒装句,倒装句又分全部倒装和部分倒装。若把整个谓语动词放在主语之前,则叫全部倒装;若把谓语动词的一部分移至主语之前,就叫部分倒装。下面作一简述。一、全部倒装1.在there,here,now,then引起的全部倒装句子中,谓语动词常为be,com e,go等。例如:H ere com es the bus.汽车来了。There goes the bell.铃响了。N ow com es your turn.现在该轮到你了。注意:如果主语是代词时,则无需倒装。例如:H ere you are.给你。A w ay she w ent.她走开了。2.以in,o…     

小议动词不定式的特殊用法

动词不定式是由“to+动词原形”构成的,to是动词不定式的符号,没有实际意义。动词不定式是一种非谓语动词形式,它没有人称和数的变化,在句子中可用作主语、表语、定语、状语、宾语及宾语补足语等,但有几种特殊用法应该引起我们的注意,现将它们归纳如下:一、当动词不定式用作后置定语时,如果动词是不及物动词,应在其后增加一个适当的介词。例如:1.W e have a lotofthings to do.(do为及物动词)2.W e can give her som ething differentto eat.(eat为及物动词)3.E ach person w illhave enough space to live in.(live为不及物动词)4.There …

“单句改(选)错”题的常见错误例析(英文)

中考英语中的“单句改(选)错”题既考查考生的基础知识,又考查考生的逻辑思维能力和综合运用语言的能力。这是一种综合性很强的题型。命题人在这种题型中设计的常见错误可归纳如下:1.主语与谓语在人称和数上不一致。例如:The C CTV news begin atseven o clock in the evening every day.A B C D犤简析犦错项为B。因为主语news是不可数名词,谓语动词应为第三人称单数形式begins。2.谓语动词的时态或语态错误。例如:H e w entto sleep w hen there was a loud knock on the door.A B C Doolrden犤简析犦错项为A。此题意为“他将要入睡…

说说being

being既可以是谓语动词,也可以是非谓语动词。作为谓语动词,其用法比较简单,主要用于构成进行时态(含被动语态的进行时态);作为非谓语动词,其用法则比较复杂,可用于引出短语构成主语、宾语、宾语补足语、定语、状语等。 一、being用作谓语动词1.当being为助动词时,用作谓语动词的being主要与过去分词连用,构成被动语态。如:I!m always being criticized.我总是挨批。He is being interviewed now.他现在正在接受面试。He is being met at the stationtonight.今晚有人去车站迎接他。2.当being为连系动词时,用作谓语动词的being主要与形…
