4周搞定2000+托福核心词
metabolism = meta(超过) + bol(抛) + ism(行为) = 抛弃旧的,完成超越→新陈代谢
metabolic = meta(超过) + bol(抛) + ic(…的) = 抛旧变新→新陈代谢的
meteor = meta(在上) + eora(空中的) = 在空中飞过→流星
meteoroid = meta(超过) + eora(空中的) + oid(像) = 流星体
appetite = ad(去,往) + pet(寻求) + ite(人或物) = 去寻求美食→食欲
magnetite = magnet(磁) + ite(人或物) = 磁铁矿
流星→陨星
meteorite
常考释义
Iridium is an element that is usually uncommon near Earth's surface, but it is abundant in some meteorites.
铱元素在地球表面很不常见,但在陨石中含量丰富。

Under that argument, academics say the giant reptiles mostly froze or starved to death when a huge cloud of particles kicked up by the meteorite blocked the world's sunlight for months.
根据这种观点,学者们认为当陨星扬起的巨大粒子云挡住了阳光,阳光长达数月无法照射到地球上时,这种大型爬行动物大部分被冻死或饿死。
It's entire life, ever since it was a bit of meteorite.
穷其一生,从它还是块陨石的时候起。

I mean, it's easier to find an iron meteorite or stony iron.
我的意思是,找到一个铁陨石或石铁更容易。

他们实际上几乎占据了所有的落到地球上的陨石材料。
来源于:听力OFFICIAL13 L6Now, we’ve been finding meteorites on earth for thousands of years.
现在,几千年来,我们已经在地球上发现的陨石,
来源于:听力OFFICIAL13 L6The larger ones that make it through the atmosphere and hit the ground are called meteorites.
较大的成功穿越大气层并砸在地面上的块片,被称为陨石。
来源于:听力OFFICIAL13 L6Uh, the thing is, what’s especially interesting about meteorites is that they come from interplanetary space, but they consist of the same chemical elements that are in matter originating on earth, just in different proportions.
呃...事情是关于陨石特别有趣的是,他们来自星际空间,但它们由来源于地球上相同的化学元素组成,只是在比例不同。
来源于:听力OFFICIAL13 L6Male professor: OK. I want to go over the different types of meteorites and what we’ve learned about them from the formation of earth and the solar system.
教授:OK,我想复习一下不同类型的陨石,我们从它们身上已经了解的地球形成的内容,以及太阳系。
来源于:听力OFFICIAL13 L6After all, the Sun has many more atoms of any element, say iron, than does a meteorite specimen, but the ratios of iron to silicon in the two kinds of matter might be comparable.
毕竟,太阳含有的任何一种元素的原子数都要比一块陨星样品含有的多,但是两者间的铁和硅的比率可能是具有可比性的。
来源于:阅读OFFICIAL22 P3To compare the compositions of a meteorite and the Sun, it is necessary that we use ratios of elements rather than simply the abundances of atoms.
为了比较陨星和太阳的组分,我们需要比较元素的比率,而不是简单地比较原子的丰度。
来源于:阅读OFFICIAL22 P3All these diverse constituents are aggregated together to form chondritic meteorites, like Allende, that have chemical compositions much like that of the Sun.
所有这些各种各样的组分被凝聚到一起形成了球粒陨石,就像与太阳具有很多相似化学组分的阿伦德陨星。
来源于:阅读OFFICIAL22 P3The first meteorite from this fall was found in the village of Pueblito de Allende.
在皮柏里托•德•阿伦德村发现了这次坠落的第一块陨石。

来源于:阅读OFFICIAL33 P3Explanations for the K-T extinction were revolutionized in 1980 when a group of physical scientists led by Luis Alvarez proposed that 65 million years ago Earth was stuck by a 10-kilometer-wide meteorite traveling at 90,000 kilometers per hour.
然而,在 1980年,路易斯•阿尔瓦雷茨带领的一组物理学家提出,在六千五百万年前,有一个10公里宽的陨星以每小时九万公里的速度撞击了地球,这使K-T灭绝成因发生革命性变化。
来源于:阅读OFFICIAL33 P3By the 1960s, both analysis of meteorites and refinements of solar evolution models converged on an age for the solar system, and hence for Earth, of 4 5 billion years.
这种方法很快让人类意识到,地球肯定有几十亿年之久,以及核融合可以为太阳长时间的发光持续供能。
