　　C. Details of Eta Carinae
　　D. Invention of a time machine
　　E. Biggest telescope
　　F Birth of the new worlds
　　1. Paragraph 1 ___.
　　1 The VLT(Very Large Telescope)is the world’s largest telescope(望远镜)and is taking astronomers(天文学家)further back to the Big Bang than they ever thought possible.Located 2,600 meters up to the Chilean Andes，it has four huge mirrors，each about the size of a London bus.The VLT is so powerful it can spot a burning match 10.000 kilometers away.
　　1. E. 分析: 段落中VLT(大望远镜)中反复出现(第2句中的代词it也是指VLT), 因此判断VLT是该段核心词, 比较被选项B和E, 判断E是答案(VLT是大望远镜, 段落中也是在强调望远镜的“大”(段落中出现了Large， largest， huge))，因此判断E是答案。
　　解题线索：利用段落中的核心词直接判断段落主题。
　　A. Events that took place before the earth existed
　　B. Power of the telescope
　　C. Details of Eta Carinae来源：https://www.hxen.com
　　D. Invention of a time machine
　　F Birth of the new worlds
　　2. Paragraph 2 ___.
　　2 This astonishing power will allow astronomers to see events in space from the birth of stars to the collision(碰撞)of galaxies(星系)on the edge of the cosmos(宇宙).The VLT is giving astronomers their best-ever view of the cosmos.The power of the VLT to see the smallest detail at the furthest distances makes its designers amazed.
　　2. B。分析：段落中VLT(大望远镜) 和power(能量)反复出现，因此这两个词是该段主题词，因此判断B是答案。
　　解题线索：利用段落中的核心词直接判断段落主题。
　　A. Events that took place before the earth existed
　　C. Details of Eta Carinae
　　D. Invention of a time machine
　　F Birth of the new worlds
　　1.Paragraph 3 ___.
　　3 Take the case of Eta Carinae，one of the most explosive stars in the universe.This star produces ultraviolet laser rays(紫外线)and it will destroy itself in a few million years’time.It is five times brighter than the sun and when it explodes it is going to be a sight worth waiting for!
　　3. C。分析：整个段落围绕Eta Carinae进行介绍：段落中的This star和代词it都是指Eta Carinae，因此Eta Carinae是段落的主题词，因此判断C是答案。
　　解题线索：利用段落中的核心词直接判断段落主题。
　　A. Events that took place before the earth existed
　　D. Invention of a time machine
　　F Birth of the new worlds
　　2.Paragraph 4 ___.
　　4But it(it指代前段中的Eta Carinae) is at distances of millions，even billions，of light years that the VLT really shows its power.The VLT can detect light that set out on its journey before the earth even existed.This gives astronomers their first—ever detailed views of events that took place in the earliest days of the cosmos.
　　4.A. 分析：比较被选项： D说“时光机器”，可是该段落提到的仪器是VLT(大望远镜)，不是“时光机器”，因此D不是答案; A中的状语结构“before the earth existed”在该段第2句中出现了，该句中没有提到A中的核心词Events(事件/事情)，但是在该段落的最后一句中出现了Events(事件)，该句说“这就使天文学家有史以来第一次观察到了宇宙早期发生的事情”，结合这个句意来看A是答案。
　　解题线索：被选项中的核心词应该在段落中有呼应的词语或结构。
　　A。 its detecting power
　　B. millions of light years away in space
　　C. the location of VLT
　　D. as an example
　　E. the birth of the earth
　　F. the rotation of the earth
　　6. The VLT will allow scientists to see events ___.
　　6.B. 分析：解题思路1：借助句子句意判断答案：空格前面内容说“VLT允许科学家观察事件…”, 判断B最合适:B作定语修饰前面的events, 整个句子大意是“VLT允许科学家观察发生在距离是数百万光年以外的事件”。解题思路2：借助句子中的特征词scientists和VLT作为答案线索，这样找到答案相关句：
　　1 The VLT(Very Large Telescope)is the world’s largest telescope(望远镜)and is taking astronomers(天文学家)(与scientists是近义词)further back to the Big Bang than they ever thought possible.带领天文学家回到远古的大爆炸时代，这是他们从没想象到的.这句话没有直接揭示答案, 接续看后面的句子,
　　2 This astonishing powe
