seem用法

一．seem常常和不定式，形容词，分词，名词和介词短语搭配。如:1．seem+不定式（短语）Iseemedtohearavoiceinthedistance我好像听到那边有声音。Youradviceseemstobedoingmeafavor.你的建议似乎帮了我个大忙。Iseemtohavecaughtacold.我好像感冒了。注意：1.seem后跟不定式（短语）时，要注意不定式所表示动作发生的时间，以此来确定不定式的时态。不定式的一般式(todo)表示的动作或状态通常发生在谓语动作之后或同时发生进行式(tobedoing)表示其动作正在进行，与谓语动词发生的动作同时进行。完成式(tohavedone)表示的动作或状态通常发生在谓语动作之前。2.seem后不定式的否定式习惯上用don’t来代替，放在seem前：Youdon’tseemtobequiteyourselftoday(=Youseemnotbequiteyourselftoday.)2.seem+形容词a)Sheseemsquitehappytoday.b)Theenemyseemspowerfulbutinfactitisweak.[注]此句式可看作是seem+tobe+adj.句式的一种简化形式。如例a可转换为：Sheseemstobequitehappytoday.例b可转换为：Theenemyseemstobepowerfulbutinfactitisweak.但目前由于英语的发展，seem+tobe+形容词结构的用法已越来越少，seem+adj的结构已趋成型，属口语语体。4、seem+名词a)Sheseemsaclevergirl.b)Hermotherseemsateacher.c)Itseemedalongtimebeforemyturncame.5.seem+介词短语Theyseemedinhighspirits.seem常用句型用于说明主语的特征或状态，表语多为名词或形容词，有时是其他的词或短语。Tomseems(tobe)averycleverboy.Mr.Blackseemed(tobe)quitehappy.一、主语+seem+(tobe)+表语二、“主语+seem+不定式”此句型中的seem与不定式一起构成复合谓语。Theyoungmanseemedtohavechangedmuch.MrsGreendoesn’tseem（或seemsnot）toliketheidea.Itseems+that从句It是形式主语，that引导主语从句。ItseemsthatnooneknowswhathashappenedintheparkItseemstomethatMrBrownwillnotcomeagain.Thereseemtobe+名词tobe可以省略，seem的单复数形式要根据后面作主和的名词的单复数形式而定。Theredoesn'tseemtobemuchhopeofourbeatingthatteam.Thereseemsnoneedtowaitlonger.
