Part-time jobs give students a sense ofachievement and acplishmentthrough contributing to the society.这句话中为什么contribute要用ing的形似呢

网友回答

1 Part-time jobs(主语) give (谓语)students(间接宾语) a sense ofachievement and acplishment(直接宾语)
through contributing to the society(方法状语)
2 through contributing to the society--------through是介词,介词后面的动词必须是“动名词形式”.
======以下答案可供参考======
供参考答案1:
因为前面是through介词,相当于介宾结构,ing是动名词,可以组成介宾结构
供参考答案2:
through是介词,介词后动词用现在分词
供参考答案3:
through在这里是介词解释因为,后面的动词用-ing形式
