1、You should take care of your -self.（名词）2、I don’t care for smoking.（动词）3、Be carefu l when you cross the street.（形容词）4、Som e careless person has broken the glass.（形容词）5、Walk carefully,or you may fall.（副词）在英语的十大词类中,动词无疑是最为活跃的词类之一.动词是构成句子的重要组成部分,它有谓语动词和非谓语动词的区别,有及物动词和不及物动词的区别,有瞬间动词和延续动词的区别,有主动语态和被动语态的区别和时态的区别.动词又可以与其他的词搭配构成丰富多彩的词组.以m ake为例：m ake friends with sb.…（与…交朋友）,m ake a film（拍电影）,make mistakes（犯错）,m ake a noise（吵闹）,make a fire（生火）,make money（挣钱）,make progress（取得进步）,make use of（利用）以及由make构成被动语态的多种用法,如：be made of…,be made from…,be made by…,be made for
…,be made in…,be made upof…等,希望考生要弄清以上这些问题.
