这是一个学英语系列专栏,每次截取一些BBC上面有趣的新闻来体会纯正的英语,并扩充大家的英语词汇量。
最近,一个火星观测卫星发现了火星上的绿色辉光。让我们来通过BBC的报道看一下这个新闻到底是怎么回事,并学习一些词汇和表达。
Scientists have identified a green light in the atmosphere of Mars.A similar glow is sometimes seen by astronauts on the space station when they look to the Earth's limb.
The glow comes from oxygen atoms when they're excited by sunlight.
The phenomenon has long been predicted to occur on other planets but the Trace Gas Orbiter (TGO) - a joint European-Russian satellite at Mars - is the first to make the observation beyond Earth.
先让我看一下那可能不那么熟悉的词汇。
glow n.辉光
limb n.四肢
Earth's limb 这里不是地球的“四肢” 而是指地球边缘
excite (物理学名词)激发
satellite n.卫星
这个片段大意是这样的:
科学家在火星大气层(atmosphere of mars)发现了一种绿光,宇航员在观察地球边缘的时候有时也会发现类似的辉光(glow)。这种辉光来自于被太阳光激发的氧原子(oxygen atoms)。 长久以来,这种现象的已经被预测会发生在其他星球,但是欧洲和俄罗斯共同拥有的微量气体轨道卫星(Trace Gas Orbiter)首次在地球外观测到这一现象。
我们来具体分析一下这句话,
The phenomenon has long been predicted to occur on other planets.
have long been 很长时间以来
It has long been known that the moon shines since it reflects the sunlight.
长久以来我们知道月球发光因为它反射太阳光。
