STEP1.现在分词作定语
现在分词及其短语可以在句子中作定语,其作用相当于一个定语从句。其动作和谓语动词同时发生,与其修饰词之间是主动关系,也就是说现在分词的动作就是它修饰的那个词的动作。
1.现在分词作定语时的位置
(1)现在分词作定语时多置于它所修饰的名词之前;分词短语用于它所修饰词的后面。例如:
He is an attacking player.他是一个攻击型的运动员。
They lived a room facing the north thirty years ago.
三十年前,他住在一个朝北的房间里。
(2)如现在分词修饰由some/any/no + thing/body/one所形成的不定代词或指示代词those时,分词在这些被修饰词的后面。例如:
Anyone swimming will be punished.正在游泳的任何人都将受到惩罚。
重点把握:动词-ing形式中的动名词也可用作定语,它表示用作…的,而现在分词作定语通常相当于一个定语从句。如:
a writing table = a table used for writing ;a sleeping boy = a boy who is sleeping
2、现在分词作定语时与谓语动词的时间关系
现在分词表进行意味和主动意味,因此,用现在分词作定语时,其表示的动作是与谓语动词同时发生的,或是正在发生的动作。例如:
There were no soldiers drilling.
= There were no soldiers who were drilling.没有士兵在操练。
The man running over there is our an.
= The man who is running over there is our an.
正在朝那边跑的那个人是我们主席。
