aux.(助动词)

could为助动词can的过去式,其后可接不带to的动词不定式。

could有两种否定形式,即couldnot和could not,其缩写形式为couldn't。这两种否定形式英美均通用,当使用could not时,特别强调not。

could用于疑问句中并不表示过去时,而是表示现在时,此时语气比较委婉,有时表示把握不大或犹豫; could用于特殊疑问句常含有惊讶、迷惑等感情色彩。

could表示“允许”,可用于人,也可表示环境、条件、法律的“允许”。could在表示“允许”时,只能指过去泛指的一般许可,而不能表示过去具体的许可。表示过去的具体许可时,可用实义动词allow, permit等。

could也可用于表示“可能性”,即环境或其他因素产生的“可能性”。这种可能性可以是将来存在的(但把握不大),也可以是现在存在的实际可能,还可用来对过去的可能性进行推测。“could+动词不定式的完成式”可表示对过去发生情况的推测,也可表示过去没有实现的可能。前者只能用于否定句和疑问句中,肯定的回答只能用could; 后者则有时带有责备意味。“could+动词不定式的完成式”可用于虚拟语气,即能做却未做的事。用于否定式则意为“虽尽力而为,但仍达不到目的”; 用于if引导的非真实条件句中,可表示与事实相反或实现的可能性不大的情况。

could还可表示过去的一般“能力”,即过去体力或智力上具有能够完成一件事情的能力或环境赋予的能力。在表示过去的一般能力时不可表示过去的“具体能力”,即过去某一特定场合进行某项具体活动的能力,并施展了这种能力。表示过去的“具体能力”时,通常用was/were able to, managed to等。但在否定句或含有否定意义的句子中,用could或was/were able to均可。

could用于虚拟语气可表示can的各种意义,如可表示能力、可以、禁止、拒绝、可能、愿望等,但比can语气委婉。

could也可用于建议做可能的事或值得做的事,还可用于表示一种结果或请求。

如果条件从句中有could,连词可省略,句子要倒装,此用法多用于书面语。

aux.(助动词)

could, can

could是can的过去式,但都表现在和将来:can比较直接,不留余地; could比较委婉,含有一定的感情色彩。
