原题目:HJ带你读外刊??Universe is expanding faster(每周一篇精读,请各位跟着我一起做到!)

导读

Universe is expanding faster

一直认为科学研究不过乎向内和向外两种,前者好比人类大脑神经和细胞,后者则延伸到浩瀚宇宙。科普文章的阅读难度一般不及人文类文章,固然多几个术语,但不会影响整体理解。考试阅读懂得经常遇到天然科学类的文章,今天就一起来看一篇科学家有关宇宙膨胀的最新报道(摘取167字),温习长句阅读。实在仅仅看一眼这幅2016年5月17日摄自于国际空间站的照片,感到就很美了。世间琐事与此相比,太微小了。

The universe is expanding faster than previously believed ? a discovery that could test part of Albert Einstein’s theory of relativity, a pillar of cosmology that has withstood challenges for a century.

【注1】首段直截了当,为了强调此最新发现,特意突出其对爱因斯坦相对论提出了挑衅,这样才干搞大么~~句子主干是The universe + is expanding + faster than (it was) previously believed,后面a discovery是主句的同位语,that引导定语从句,修饰a discovery;a pillar of cosmology是theory of relativity的同位语,起说明作用,that引导定语从句,修饰a pillar of cosmology。

NASA and the European Space Agency jointly announced the universe is expanding 5% to 9% faster than predicted, a finding they reached after using the Hubble space telescope to measure the distance to stars in 19 galaxies beyond the Milky Way.

【注2】第二段详细解释最新研究与之前的差别。句子主干是NASA and the European Space Agency + announced + (that) the universe is expanding 5% to 9% faster than predicted,后面a finding与第一段a discovery用法一样,they reached … Milky Way是定语从句修饰afinding,省略了that,即a finding (that) they reached…。

The rate of expansion did not match predictions based on measurements of radiation left over from the Big Bang that gave rise to the known universe 13.8bn years ago. One possibility for the discrepancy is that the universe has unknown subatomic particles, similar to neutrinos, which travel nearly as fast as the speed of light, about 186,000 miles (300,000km) per second.

【注3】第三段阐明了可能导致两种研究差异的原因。第一句主干是the rate of expansion + didn’t match + predictions,后面based on…radiation是从前分词短语后置,修饰predictions,相当于predictions which are based on…;left over from the Big Bang同样用法,修饰radiation;that引导定语从句,修饰theBig Bang。

【注4】第二句主干是One possibility is + that引导的表语从句,表现possibility内容;similar to neutrinos是形容词短语后置,修饰unknown subatomic particles;which引导定语从句,修饰neutrinos。

The speedier universe also raises the possibility that Einstein’s general theory of relativity, which serves as the mathematical scaffolding for calculating how the basic building blocks of matter interact, is slightly wrong, NASA said.

【注5】最后一段再次强调新发现对爱因斯坦相对论提出了挑战。句子主干是The speedier universe + raises + the possibility,后面that引导同位语从句,说明possibility的内容。同位语从句中的构造是Einstein’s general theory of relativity + is + slightly wrong,中间which引导定语从句,弥补说明theory of relativity。How引导宾语从句,其结构是how + the basic building blocks of matter + interact。

4.galaxy ['g?l?ks?] n. 星系

5.Milky Way 银河系

6.measure ['me??] v. 测量

7.radiation[re?d?'e??(?)n] n. 辐射

8.leave over 留下,剩下

9.give rise to 导致

10.subatomic [s?b?'t?m?k] adj. 亚原子的

11.neutrino [nju?'tri?n??] n. 中微子

12.scaffolding ['sk?f??ld??] n. 脚手架;框架,平台

13.interact [?nt?r'?kt] v. 相互作用

HJ原创译文:

宇宙的膨胀速度比原先认为的更快??这一发现可能对阿尔伯特?爱因斯坦相对论的部分内容提出了考验,一个世纪以来后者作为宇宙学研究的支柱理论经受住了屡次质疑。

在应用哈勃太空望远镜对银河系之外19个星系的行星距离进行测量后,美国国家航空航天局和欧洲太空总署结合宣布宇宙的膨胀速度比之前预测的快5%-9%。

宇宙膨胀的速度与先前依据大爆炸留下的辐射丈量成果所作的预测不一致,一般认为宇宙是由138亿年前的大爆炸发生的。导致数据不一致的一种可能是:宇宙中存在相似于中微子的未知亚原子微粒,中微子的运动速度亲近光速,到达每秒约30万公里。

美国航空航天局(NASA)以为,宇宙更快的膨胀速度也可能表明爱因斯坦狭义相对论存在稍微的差错,在盘算物质根本组成成分如何相互作用方面,广义相对论一直被当作数学实践基础。
