描写水星的英语作文篇一:

Ever wonder what it's like on other planets? On this Moment of Science, find out what it's like on Mercury.

The great astronomer(天文学家) Carl Sagan used to say that if he were transported anywhere in the solar system he would know which planet he was on just by looking around. In this spirit of knowing your neighborhood, here's something we call . . . What's It Like There?

Today we ask: What's it like . . . on Mercury?

You're standing at the equator(赤道) on Mercury just before sunrise. We'd better put you in a protective shelter, because it's mighty(很，非常) cold–something around three hundred degrees below zero, Fahrenheit(华氏温度计的). That's cold enough to freeze methane(甲烷，沼气).

But things are looking up–by midmorning(上午中段时间，上午十点左右) it should be a (1)balmy(温和的) eighty degrees outside. Of course, because of its rotation(自转) and orbit(公转), midmorning on Mercury comes twenty Earth days later, so you have a long wait.

When it finally arrives, though, you step outside in a protective suit and (2)bounce(跳) around in the low gravity. The ground is rocky and covered in craters(火山口). There's no atmosphere at all, so the sky overhead(在头顶上) is black, even though the sun is perfectly visible.

In fact, the sun is far bigger, and brighter, than you've ever seen it on Earth–imagine a sun eleven times as bright! Not only that, the temperature is still climbing(上升的). By high noon it will be up to eight hundred degrees Fahrenheit, hot enough to melt zinc(锌). Clearly this is no place for humans.

Every Mercurial day, which lasts one hundred and seventy six Earth days, the planet undergoes the same unbelievable temperature fluctuation(温度波动) from super-cold to super-hot. Makes you glad to have a nice, temperate planet like Earth to come back to.
