想请教各位,
有个问题想请教您, 以下的这个句子是我自己造的:
The citizens of that area have long ignored the threat of air pollution,
causing their health to become worse year by year.
想请问:
1. causing 也可写成 ,which causes; 指的是ignoring 这件事. (不知是否正确?)
2. 如果我想要说明的是 air pollution 这个现像, 那这在个句子中, 我要怎么用关
代来修饰呢? (是不是就用 which causes; which 前面不加逗点, 不知是否正确)
谢谢
