问题详情:
Water is a hquid (渍体) ; but it can also be a solid when it is very cold and turns to ice. It can also be a gas, when it evaporates (蒸发) and become water vapour (水蒸气) .
The water cycle
Water is very important, and without it life on Earth should be impossible. The oceans that
cover three quarters of the Earth’s surface can be thought of as our great water reservoirs. All the
time, water is being evaporated from the ocean’s surface by the warmth of the sun. High in the sky this water vapour, turns into clouds which drift (漂浮 ) over the land, often creating rainfall. As the rain falls,it seeps (滂漏 ) into the soil and then into rivers that flow back into the oceans, where it is ready to begin all over again!
下而是被打乱的有关The water cycle(水循环)的信息,请根据短文内容重新排序。
请将*编号涂卡。首句己给出:

A. Rains falls from the clouds. B. The rivers take the water back to the sea. C. The clouds drift over the land. D. The water seeps through the soil and back into rivers. E. At the watch vapour cools,it turns into clouds. |
