The child seemed to be tired

问题描述:

The child seemed to be tired
the child seemed to be tired
也可以写成the child seemed tired
后者我知道是连缀动词seem后面直接跟形容词tired
我不知道的是为什么第一句要加一个to be ,加一个不定式是虾米意思啊?

seem为连缀动词
seem后面即可跟不定式,也可跟形容词
tired为过去分词,可做形容词用
这句话可以直接写成the child seemed tired
但是如果你硬是要用不定式的话,to后面要跟动词原形
所以不能用to tired,只能用to be,然后再接一个tired
