用法辨析
- should是助动词shall的过去式,只用于第一人 称:①用于陈述语气:构成第一人称过去将来时、过去将来完成时以及过去将来进行时。②用于主句中构成虚拟语气:“should+动词不定式的原形”表示虚拟结果时指现在,表示推测结果时指将来; “should+动词不定式的完成式”也表示虚拟结果或推测结果,但使用范围较窄,一般表示一件事情根据条件本可能实现,但由于没有根据条件或条件不存在,因而没有实现,即表示与过去事实相反。在并不强调由于某种条件而产生某种结果时往往不带条件状语或条件状语分句。③构成第一人称委婉、谦逊的语气。④I should like用来表示愿望或意向,有时也可表示犹豫。后接动词不定式的一般式时表示现在或将来可能实现也可能不实现的愿望; 后接动词不定式的完成式时表示对过去一件未做的事情感到惋惜; like用完成式,后接动词不定式的一般式时表示过去有做一件事的愿望,但由于某种原因,这件事未做成,在该结构中like也可以名词作宾语。
- should用作情态动词shall的过去式:①用于陈述语气:shall用于第二、第三人称时表示命令、许诺、威胁、警告、禁止等,当它指的是过去事件时就要用should。在表示意向、要求、决定、建议等意义的从句里,如果主句的谓语动词是过去式,则从句中的should既可看作情态动词shall的陈述语气过去式,也可看作它的虚拟语气,但当句子的语气不够委婉时宜看作前者。②用于虚拟条件从句中,可用于各种人称,有以下两种含意:一是表示对将来事件的推测,相当于汉语中的“万一”,这时主句往往不用虚拟语气,而用陈述语气或祈使语气; 二是表示虚拟让步。③在表示命令、要求、建议等意义的词所支配的分句里,通常也用should来构成虚拟语气,这时无论主句用现在式或过去式,从句都可用should,这样的结构主要有以下两种:一是表示命令、要求、建议等意义的动词(如advice, demand, intend等等)或名词(如recommendation, suggestion等等)+that-clause; 二是It is necessary〔desirable, essential, important等〕+that-clause。④表示惊愕、遗憾、欣慰、悔恨、失望、突然、出乎意料等感情。⑤表示有很大可能性,是预期中的,几乎是必然的。
- should用作独立情态动词:①表示责任、义务或正当的行为。②表示适当、得宜,可以构成劝告或委婉的命令,这是表达说话人意志的谦逊有礼貌的用语。③“should+动词不定式的完成式”表示在某时间之前应已完成但没有完成的行为; 也可表示在某一时间之前做了的事情是应当做的。④should常与疑问词连用表示不感兴趣、难以相信等较强烈的感情。⑤should常用在lest, that, so that, in order that引导的从句中,表示期望、结果或目的。
