Billions of years ago，there was a time before stars or before lights，called the Dark Ages.There used to be not enough material of high densities(密度) to cause nuclear explosion.Without nuclear explosion，there were no stars. 2 What ended the Dark Ages was the birth of the first stars，thought to be the Cosmic(宇宙) Dawn.And this marked the age of light in our universe.Stars began shining and galaxies started forming. Those first stars burned fiercely and died quickly.None of them survived to the present day. 3 They shone so brightly that their light may still be visible today after traveling billions of light years. Recently，a team of astronomers used 70 hours of observing time to take pictures of six extremely distant galaxies. 4 They also calculated that the Cosmic Dawn started to burn between 250 and 350 million years after the Big Bang.That means it took a long time for the initial gas out of the Big Bang to cool and form the first generation of stars. Hopefully，upcoming missions will be able to directly observe those galaxies in greater detail.And some star mysteries will be disclosed. 5 How long did it take for the first stars to live and die? How did the stars transform the cosmic to give us the universe that we know today? A．Nevertheless，they left their mark. B．Accordingly，there was no visible light either. C．Each one also poured out light into the empty universe. D．It was much darker than it is today with only a little light. E．For example，when did the Cosmic Dawn exactly take place? F．Based on their observations，they were able to estimate the age of the galaxies. G．They’re so far away that we can’t capture them even with powerful telescopes. 语篇解读　这是一篇说明文。本文阐述了最早的星星是什么时候开始发光的。 1．答案　C 解析　根据下一句“But when did the first stars shine？”可知，C项“每一颗星星都把光注入了空荡荡的宇宙”切题，引出下文的问题，且与前一句的句式一致，选项中的“light”对应下一句中的“shine”。故选C项。 2．答案　B 解析　上文提到了黑暗时代没有核爆炸，也就没有星星，因此，B项“相应地，那时也没有可见的光”切题，与上文构成递进关系，该选项中的“no visible light”与上文中的“before lights”相呼应。故选B项。 3．答案　A 解析　上文提到第一批恒星猛烈燃烧，很快就消失了，没有幸存至今，而下文则说到它们发出的光至今可见，由此推知A项“然而，他们留下了自己的印记”切题，承上启下，且该选项中的“left their mark”对应下文中的“still be visible today”。故选A项。 4．答案　F 解析　根据上一句可推知，下文可能提到这些天文学家的观测结果，因此，F项“基于他们的观测，他们可以推测这些星系的年代”切题，该选项中的“observations”对应上文中的“observing”。故选F项。 5．答案　E 解析　根据上一句“And some star mysteries will be disclosed.”可知，E选项承接上文，阐述了第一个可能被解决的问题：宇宙黎明究竟是什么时候发生的，且与下文的两个问题构成时间上的先后顺序。故选E项。 学科网（北京）股份有限公司 $$
