　　在我们享受的时候懂得珍惜

　　cherish what we are enjoying

　　it is a report about the new planet which holds possibility for life.

　　这是一篇关于发现了一颗有生命可能性的星球的报告。

　　it shows that european astronomers have discovered a new planet, they name it gliese581c.

　　说欧洲天文学家们发现了一颗新的星球，代号为“gliese581c”。

　　it is about light years from our earth. they estimated the planet"s average temperature at between 0 and40 degrees centigrade. it is orbiting the red dwarf star, gliese581.

　　它距地球约光年。他们估计它的平均温度约在0℃～40℃之间。它围绕着红矮星gliese581运行。

　　most important of all, it’s an earth-like planet. there might be mountin, sea and liquid water.

　　最重要的是，这颗星球和地球非常相似，它可能有山峦，有海洋，还有液态水。

　　so the astronomers believe that it is potentially habitable.

　　所以科学家们相信它能支持生命的存在。

　　however, gliese581c might be "tidally locked" to it’s sun-the dwarf star the way our moon is to the earth.

　　然而，就像月球一样，它只会公转，不会自转。

　　it means that it must always show its same face to its sun, and that while one side would be too fiercely hot to support life, the other side would be too cold.

　　这就意味着它面对红矮星的一面会太热不适合生命体而背对红矮星的一面则会很寒冷。 《1》《2》
