导语:ability 几个表能力单词巧辨析
Lesson two
搞笑神句
问:Does the pig have the ability to fly?
答:The monkey has the ability to see.
【惯用句式】have/has the ability to do sth 有能力去做某事
例:One must have the ability to work with others.
【词中词法】able(有才能的, 能够的)
ability是able的名词形式,其反义词为unable
补充句式:be able to do sth
例:Will you be able to come and help us clean the room?
������易错点:can与able辨析
巧记两个点—区分重在时态和位置的用法不同������
can/could 表示能力;可能 (过去时用could),
只用于现在式和过去式(could)。be able to可以用于各种时态。
They will be able to tell you the news soon.
������������ could限(现过),be able to 不限时态
2)只用be able to
a. 位于助动词后。 b. 情态动词后。
c. 表示过去某时刻动作时。 d. 用于句首表示条件。
e. 表示成功地做了某事时,只能用was/were able to, 不能用could。
He was able to flee Europe before the war broke out. 在战争爆发前逃往欧洲。
注意:could不表示时态
1)提出委婉的请求
(注意在回答中不可用could)。
— Could I have the television on?
—Yes, you can. / No, you can't.
2)在否定,疑问句中表示推测或怀疑。
He couldn't be a bad man.
