careful的用法
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(www.yywords.com): 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。 (摘自《中学英语高频词详解词典》金盾出版社) 引用地址: |
