seem的用法是什么?
seem相当于系动词 在英语所有的连系动词中,除了be这个最常见的外,seem应该算是最常见的连系动词之一.而对于seem的用法,许多同学有个误解,就是以为seem后接表语时,表语前可随意地加上to be,也可随意地去掉to be.其实,seem后to be的省略和保留有不少讲究和值得注意的地方,本文归纳以下五种情况,供同学们参考. 一、后接形容词时 当seem后接形容词作表语时,如果谈的是客观事实,即看上去肯定是真实的东西,通常用seem to be;如果谈的是主观印象,则通常只用seem.但由于这种区别在没有上下文的情况下并不总是很清楚,所以在许多情况下两个结构均可以用.如: He seems (to be) ill. 他似乎生病了. He seems (to be) quite happy. 他似乎很高兴. He seems (to be) quite rich 他似乎相当富有. She seems (to be) very sleepy today. 今天她看上去很困倦. 但在有些情况下,由于其语境比较特殊,可能用其中一个结构比另一个结构更合适,如下面一句中的seems后最好不用to be: He seems older than he is. 他看上去比实际年龄大. 二、后接名词时 在名词前通常要用seem to be(尤其是当名词前带有定冠词或物主代词修饰时),如以下各句中的to be均不能省略.如: He seemed to be the owner of the car. 他好像就是车主. I spoke to a man who seemed to be the boss. 我跟一个人说话,他看上去像是老板. Washing the car seems to be your main hobby. 洗车似乎是你的主要爱好. 但是,在着重表现主观感受的名词短语前,有时可以省去to be.此时名词前通常会有一个描绘性形容词修饰.如: It seems (to be) a good idea. 那似乎是个好主意. It seems (to be) a real bargain. 这东西似乎很便宜. 下面一句中的fool前虽然没有形容词修饰,但a fool本身相当于形容词foolish: He seems (to be) a fool. 他似乎是个笨蛋. 三、后接非谓语动词时 后接不定式的被动式时,有时可以省略to be,而只保留过去分词(尤其是当其中的过去分词可用作形容词时更是如此).如: Ann and Robert seem (to be) made for each other. 安和罗伯特真似天生的一对. She didn’t seem (to be) convinced by the argument. 这个论点似乎没有使她信服. 但后接不定式的进行式时,通常不能省略to be,因为seem后习惯上不接现在分词作表语.所以,下面各句中的to be均不宜省略: He seems to be saying something. 他似乎在说什么. History seems to be repeating itself. 历史似乎在重演. His health seems to be improving little by little. 他健康状况看来正在好转. 注:如果seem to be doing sth结构中的doing 不是现在分词,而是形容词,则可省略其中的to be.如: His idea seems (to be) exciting. 他的主意看来令人激动. She seemed (to be) lacking in enthusiasm. 她似乎缺乏热情. 四、用于there be结构时 当seem用于there be结构时,其通常的表现形式为There seems to be…,其中的to be可以省略,也可以保留,但以保留为多见.如: There seems to be something wrong here. 这儿好像有点不大对劲. There seems to be a mistake in these figures. 这些数字中好像有个错误. There seemed (to be) nobody about, so I went in. 附近似乎没有人,因此我就走了进去. There seems (to be) every reason to believe that business will get better. 看来完全有理由相信生意会转好. 注:省略to be后,seem便直接充当了be的作用. 五、后接表语形容词时 在作表语用的以a-开头的形容词前通常不能省略to be.
