it is a report about the new planet which holds possibility for life.
這是一篇關於發現了一顆有生命可能性的星球的報告。
it shows that european astronomers have discovered a new planet, they name it gliese 581 c.
說歐洲天文學家們發現了一顆新的星球，代號為“gliese 581c”。
it is about 20.5 light years from our earth. they estimated the planet's average temperature at between 0 and 40 degrees centigrade. it is orbiting the red dwarf star, gliese 581.
它距地球約20.5光年。他們估計它的平均溫度約在0℃～40℃之間。它圍繞著紅矮星gliese 581執行。
most important of all, it’s an earth-like planet. there might be mountin, sea and liquid water.
最重要的是，這顆星球和地球非常相似，它可能有山巒，有海洋，還有液態水。
so the astronomers believe that it is potentially habitable.
所以科學家們相信它能支援生命的存在。
however, gliese 581 c might be "tidally locked" to it’s sun-the dwarf star the way our moon is to the earth.
然而，就像月球一樣，它只會公轉，不會自轉。
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.
這就意味著它面對紅矮星的一面會太熱不適合生命體而背對紅矮星的一面則會很寒冷。
this report makes me to realize that how valuable our earth is.
這使我認識到我們地球有多麼珍貴!
everyday, we can see sunrise and sunset.
我們每天都可以看到日出日落。
the day and night keeps on exchanging. it’s not too hot in the daytime while not to cold at night.
一天早晚有變化，晝夜不停地交換使白天不過分熱，夜晚不過分冷。
everyday, i go to school cheerfully in the morning and skip along at the way home as the sun set.
清爽的早晨，我可以揹著小書包高高興興地去上學。夕陽西下，我又蹦又跳地回到家。
