（单词翻译）
These huge tracks of rainforest close to the Queensland coast are essential because they regulate the flow of water and the sediment1 it contains. That’s important, because there’s an awful lot of water here.
Hot humid tropical air gives rise to vast amounts of rainfall. It pours for at least 120 days a year. And as much as 60 centimeters can fall in a single day. It’s one of the wettest places on earth. Left unchecked by the forest, the water would wash out
sediments2 and
smother3 marine4 life. But waterways flowing off the rainforest are
relatively5 clear, and many are spectacular.
