Like many other nations , mainland China also has air pollution problems. The government believes that if people know more about the problem , they will want to do something about it.
請問知識大大們,此句後段the problem為什麼不是用複數the problems呢?如果用複數the problems,那後面接得句子是不是要變成 they will want to do something about them.呢?謝謝:)
