Have you noticed that it's getting warmer
and warmer every year? To put it simply
that's because of air pollution. Scientists tell
us that because of air pollution, the earth's
heat cannot escape. This is known as global
warming. If this situation is allowed to
continue, it will just keep getting hotter an
hotter. Then, can you imagine what will
happen? We should all, therefore, do our
part to stop polluting the air and help save
the world.
全球氣溫上升
你有沒有注意到天氣一年比一年變得還要暖和了呢?簡言
之，那是因為空氣污染的緣故。科學家告訴我們由于空氣污染，
地球的熱氣無法散出去。這就是為人所知的全球變暖。如果我們
任由這種情形一直持續下去，地球就會變得越來越熱。那么，你
能想像會發生什么事嗎?因此，我們全都應該盡一己之力來防止
污染空氣并拯救地球。
