作者: admin来源: 网络文章 时间: 2019-03-12

一、able

1. 表示“有能力的”“能干的”,可用作表语或定语。如:

He is an able manager. 他是位有能力的经理。

He is old but still able. 他虽年老,但仍有很能干。

2. 通常用于 be able to do sth结构,其意为“能做某事”“会做某事”。如:

He is able to speak English. 他会说英语。

Everyone here is able to type. 这儿的每一个人都会打字。

He will be able to get about in a week or two. 再过一两个星期左右他就能走动了。

He studied hard and was able to pass his examinations. 他学习很努力,所以考试及了格。

be able to 不仅有多种时态形式(通常不用于进行时或与 be going to 连用),而且还可以与某些情态动词连用(通常不与 can 连用),甚至还可以有非谓语形式。如:

Since his accident he hasn't been able to leave the house. 自出事之后,他一直未能离开家。

You might be able to persuade him. 你也许能够说服他。

I hope to be able to do the work. 我希望能干得了这项工作。

二、ability

1. 表示抽象意义的“能力”,为不可数名词。如:

He is a man of ability. 他是位有能力的人。

He is behind the others in ability. 他在能力上比别人差。

若表示不同种类的能力,则可以用复数。如:

listening, speaking, reading and writing abilities 听说读写能力

Men and women have similar abilities and needs. 男人和女人的能力和需要是相似的。

侧重指智慧、天资、天分等方面的意义时,可数或不可数均可能,有时还可用复数形式。如:

The girl has a great musical ability 这女孩很有音乐天才。

Everyone admired his abilities. 大家都敬佩他的才能。

2. 表示有能力做某事或具有做某事的能力等,其后通常要接不定式。如:

He has the ability to speak English fluently. 他能流利地说英语。

The ability to be clearly heard is extremely important for newsreaders. 声音宏亮清晰对新闻广播员来说极为重要。

按英语习惯,ability一般不接of doing sth,但有时可接in doing sth。如:
