宾语补足语是用来说明宾语的性质特征的,例如:You will find him at work.这里介词短语at work就是用来补充说明him的动作特征的.
定语是用来修饰名词的,相当于形容词的作用.只不过介词短语作定语是要后置修饰名词,例如:The cute boy in blue jeans.这里介词短语in blue jeans就是后置修饰boy.译为:穿蓝色裤子的那个男孩
宾语和宾语补足语有一个重要特点:就是在宾语的后面加上be动词,若能构成一个语义通顺的句子,则是补足语,否则是直接宾语.请看例句:
I made John our chairman (加be动词,John is our chairman,这讲的通所以our chairman 是补足语)
I made John a cake (加be动词,John is a cake,这显然不合逻辑,所以a cake 是直接宾语)
再回过头来看前面那个例子:You will find him at work(加be动词,He is at work,这讲的通,所以at work这个介词短语是宾语补足语)
很晚啦就讲到这,
