不定冠词连用抽象名词的三种情况1. 有些抽象名词由于可以由于含义的变化,转化成了个体名词,故可连用不定冠词。如:She is quite a beauty. 她真是个美人儿。It’s a pity to leave so early. 这么早就走真是遗憾。It’s a pleasure to be with you. 跟你在一起是愉快的。We judged the London visit a success. 我们认为这次伦敦之行很成功。2. 有些单形的抽象名词是由动词转化来的,也常与不定冠词连用。如:Let’s have a try at it. 让我们试它一下。Give the clothes a good boil. 把衣服好好煮一煮。I felt a touch on my arm. 我觉得臂上有人碰了一下。Shall we go for a swim tomorrow? 我们明天去游泳好吗?3. 用于某些固定搭配中,如at a loss, in a hurry, as a rule, once upon a time, all of a sudden等。如:I was at a loss for words. 我不知说什么好。You aren’t in a hurry but I am. 你不着急,我可着急。■ 不定冠词可用于复数名词前吗少数搭配中可以。主要见于以下情况:1. 用于“不定冠词+形容词+复形抽象名词”结构,这结构多用于表示时间、距离、金钱等,如a full six hours(足足6小时)、a busy two weeks(忙碌的两星期)、a good two miles(足足两英里)、a good five dollars(整整5美元)等。如:I’ve had a busy two weeks. 我忙了两个星期。It’s a good three miles to the station. 离车站至少三英里。Her dress was a full three inches above the knee. 她的连衣裙下摆离膝盖整整三英寸。2. 用于某些习语中,如a few, a great many等。如:A great many people were at the meeting. 很多人参加了会。There were a good few copies sold on the first day. 第一天就卖了许多本。注意:有些名词虽然带有复数词尾,但它们本身可以用作单数可数名词,此时自然可在其前使用不定冠词。如:We came to a crossroads. 我们来到了十字路口。This is a means to an end. 这是达到目的的一种手段。
