able的副词形式及用法!

提问时间:2021-03-01

答案
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.用于 be able to do sth(能或会做做某事).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.
注: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.
I regret not being able to help her.我很遗憾未能帮助她.
3.able 的比较级和最高级通常是 abler 和 ablest,也可以是 more able 和 most able,有时还可用 better able和best able.如:
You are better able to do it than I (am).你比我更有能力做这件事.
She’s the person best able to cope.她是个最能妥善处理问题的人.
4.若要加强语气,其前除可very,quite,perfectly等修饰外,有时还可用well修饰.如:
He is quite [well] able to take care of himself.他完全有能力照顾自己.
He’s a very able student; he’s just too lazy.他是个很有能力的学生,只是太懒了.
若受just,only just修饰,则表示“只能”“仅能”.如:
I was just able to make out a dark figure in the distance.我只能看见远处有个黑影.
5.able的反义词是unable(不能的,不是disable,后者是动词,其意为“使残废”“使无能力”.比较:
They were unable to reach a decision.他们没法做出决定.
Now that he was disabled,his house had become a prison to him.因为他残废了,他的房子就成了他的牢笼.
