形容词careful
与careless的搭配与用法
一、careful
的搭配与用法
1. 后接介词
of 或 about,
表示“当心”“留意”等。如：
Be careful of the dog; it sometimes
bites people. 当心那条狗，它有时候咬人。
You must be careful of [about] your
pronunciation. 你要注意你的发音。
be careful 后一般不接介词
for。如：
我希望你要多注意身体。
正：I hope you’ll be more careful of
[about] your health.
误：I hope you’ll be more careful for
your health.
2.
表示做某事时要小心或仔细，其后通常接 in doing
sth。如：
Be careful in crossing the
street. 过马路时小心。
You cannot be too careful
in driving a car.
开车时再怎么小心也不为过。
如果后接名词，则通常用介词with。如：
Do be careful with that vase!
务必小心那个花瓶！
You have to be careful with people
you don’t know. 对不认识的人得当心。
3.
后接不定式，表示注意要做某事。如：
Be careful not to drop it.
小心不要把它掉了。
You must be careful to avoid being
caught. 你必须小心，不要被抓住。
注意该用法与后接in doing
sth的区别。比较：
He’s careful to read every sentence.
他注意读（即不漏读）每一个句子。
He’s careful in reading every
sentence. 他读每个句子都很仔细。
4.
其后可接从句作宾语。如：
Be careful how you hold it.
小心拿好。
Do be careful (about) what you say.
说话一定要小心。
后接 what 从句时，可用介词
of, about 等，但通常省略，但是若是接
that, how, when, where
等引导的从句，则一般不用介词；另外，从句谓语若指将来，通常要用一般现在时代替将来时。如：
Be careful that you don’t hurt her
feelings. (=Be careful not to hurt her feelings).
当心别伤害她的感情。
二careless
的搭配与用法
1.
表示某人做某事很粗心，通常用于it is careless of
sb do sth。如：
It was careless of you to leave your
camera in the taxi.
你把照相机留在计程车里实在太不小心了。
该句式也可换成以“人”作主语的句子。如：
你犯这样的错误真是粗心。
It was careless of you to make such a
mistake.
=You were careless to make such a
mistake.
注意，这样用时句首的it为形式主语，不能改为
that。但是这类句子后面不出现不定式，那么句首的it也可换为
that。如：
It was very careless of him.=That’s
very careless of him. 他太粗心了。
2.
比较be careless to do sth与be
careless in doing sth：前者中的不定式为结果状语，指由于粗心而做了某事；后者中的in
doing
sth表示时间，其中的in相当于while，指在做某事时很粗心。如：
He was careless to make
the mistake. 他很粗心，结果出了错。
He was careless in
typing the letter. 他打这封信时很粗心。
3.
表示“对……不在意或不关心”等，其后可接介词 about, of,
with 等。如：

[with] his health. 她不注意身体。
He is careless with his
pronunciation. 他对语音不注意。
Don’t be so careless with
your money. 你花钱不要这样随便。
