Once your business becomes international,________ constantly will be part of your life.(Unit3-5)为什么用flying不用flight?请分析一下句型或语法.可是我认为这里缺主语,constantly应该修饰will be part of这里面的动词.

问题描述:

Once your business becomes international,________ constantly will be part of your life.(Unit3-5)
为什么用flying不用flight?请分析一下句型或语法.
可是我认为这里缺主语,constantly应该修饰will be part of这里面的动词.

看到constantly吗 副词修饰形容词和动词
前面显然不能用名词flight
当然flying也有名词的意思
但是这句话是动词ing作主语的形式
