　　A Star Is Born

　　1 The VLT(Very Large Telescope)is the world’s largest telescope(望遠(yuǎn)鏡)and is taking astronomers(天文學(xué)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.

　　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.

　　3 Take the case of Eta Carinae，one of the most explosive stars in the universe.This star produces ultraviolet laser rays(紫外線)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!

　　4 But it 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.

　　5 In other words.the VLT is a kind of a time machine.It takes astronomers back to a time when complete galaxies crashed into each other.The effects of these past collisions can now be seen by scientists，and astronomers believe the telescope will reveal more about these exciting events in the years to come.One day, we might be able to say we have traveled back to the beginning of time，and we will have a much clearer picture of how our planet was born.

　　答案與解析:

　　第一步: 分析文章標(biāo)題A Star Is Born

　　標(biāo)題中的星星到底是什么?結(jié)合文章開(kāi)頭的句子：

　　文章第一段中沒(méi)有出現(xiàn)Star這個(gè)詞，但是根據(jù)文章中出現(xiàn)的中文注釋：望遠(yuǎn)鏡，天文學(xué)家，星系，宇宙(第二段)等詞，可以知道文章標(biāo)題中的Star應(yīng)該是指宇宙中的某顆星星。從標(biāo)題內(nèi)容來(lái)看，這篇文章應(yīng)該是說(shuō)明文，可能將具體講述某顆星星的誕生過(guò)程。

　　解題第2步：結(jié)合文章主題(文章標(biāo)題所揭示的內(nèi)容)分析概括大意被選項(xiàng)之間的關(guān)系。

　　A. Events that took place before the earth existed

　　B. Power of the telescope

　　C. Details of Eta Carinae

　　D. Invention of a time machine

　　E. Biggest telescope

　　F Birth of the new worlds

　　被選項(xiàng)中B和E都涉及到“telescope(望遠(yuǎn)鏡)”，因此推測(cè)這兩個(gè)選項(xiàng)中應(yīng)該至少有一個(gè)是答案(提示：相關(guān)選項(xiàng)中通常出答案); F 與文章主題(一顆星星的誕生)呼應(yīng)，所以成為答案的可能性較大， C中出現(xiàn)了特征詞Eta Carinae，所以C在解題中容易被判斷。

　　第3步：直接解題，在解題中注意各種解題技巧的巧妙運(yùn)用。

　　A. Events that took place before the earth existed

　　B. Power of the telescope

　　C. Details of Eta Carinae

　　D. Invention of a time machine

　　E. Biggest telescope

　　F Birth of the new worlds

　　1. Paragraph 1 ___.

　　1. E. 分析: 段落中VLT(大望遠(yuǎn)鏡)中反復(fù)出現(xiàn)(第2句中的代詞it也是指VLT), 因此判斷VLT是該段核心詞, 比較被選項(xiàng)B和E, 判斷E是答案(VLT是大望遠(yuǎn)鏡, 段落中也是在強(qiáng)調(diào)望遠(yuǎn)鏡的“大”(段落中出現(xiàn)了Large， largest， huge))，因此判斷E是答案。

　　解題線索：利用段落中的核心詞直接判斷段落主題。

　　A. Events that took place before the earth existed

　　B. Power of the telescope

　　C. Details of Eta Carinae

　　D. Invention of a time machine

　　F Birth of the new worlds

　　2. Paragraph 2 ___.

　　2. B。分析：段落中VLT(大望遠(yuǎn)鏡) 和power(能量)反復(fù)出現(xiàn)，因此這兩個(gè)詞是該段主題詞，因此判斷B是答案。

　　解題線索：利用段落中的核心詞直接判斷段落主題。

　　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. C。分析：整個(gè)段落圍繞Eta Carinae進(jìn)行介紹：段落中的This star和代詞it都是指Eta Carinae，因此Eta Carinae是段落的主題詞，因此判斷C是答案。

　　解題線索：利用段落中的核心詞直接判斷段落主題。

　　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：比較被選項(xiàng)： D說(shuō)“時(shí)光機(jī)器”，可是該段落提到的儀器是VLT(大望遠(yuǎn)鏡)，不是“時(shí)光機(jī)器”，因此D不是答案; A中的狀語(yǔ)結(jié)構(gòu)“before the earth existed”在該段第2句中出現(xiàn)了，該句中沒(méi)有提到A中的核心詞Events(事件/事情)，但是在該段落的最后一句中出現(xiàn)了Events(事件)，該句說(shuō)“這就使天文學(xué)家有史以來(lái)第一次觀察到了宇宙早期發(fā)生的事情”，結(jié)合這個(gè)句意來(lái)看A是答案。

　　解題線索：被選項(xiàng)中的核心詞應(yīng)該在段落中有呼應(yīng)的詞語(yǔ)或結(jié)構(gòu)。

　　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：解題思路1：借助句子句意判斷答案：空格前面內(nèi)容說(shuō)“VLT允許科學(xué)家觀察事件…”, 判斷B最合適:B作定語(yǔ)修飾前面的events, 整個(gè)句子大意是“VLT允許科學(xué)家觀察發(fā)生在距離是數(shù)百萬(wàn)光年以外的事件”。解題思路2：借助句子中的特征詞scientists和VLT作為答案線索，這樣找到答案相關(guān)句：

　　1 The VLT(Very Large Telescope)is the world’s largest telescope(望遠(yuǎn)鏡)and is taking astronomers(天文學(xué)家)(與scientists是近義詞)further back to the Big Bang than they ever thought possible.帶領(lǐng)天文學(xué)家回到遠(yuǎn)古的大爆炸時(shí)代，這是他們從沒(méi)想象到的.這句話沒(méi)有直接揭示答案, 接續(xù)看后面的句子,

　　2 This astonishing power (指代VLT的驚人能力)will allow astronomers (與scientists是近義詞)to see events in space from the birth of stars to the collision of galaxies(星系)on the edge of the cosmos.該句也沒(méi)有直接揭示答案, 接續(xù)看后面的句子: 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.該句說(shuō)“VLT能使天文學(xué)家看見(jiàn)宇宙中最遠(yuǎn)地方發(fā)生的最小的事情，這使它的設(shè)計(jì)者很吃驚?！?該句間接的揭示了答案。

　　考點(diǎn)：考察考生對(duì)文章中重要細(xì)節(jié)內(nèi)容的歸納總結(jié)。VLT是文章中涉及到的重要細(xì)節(jié)。

　　A。 its detecting power

　　C. the location of VLT

　　D. as an example

　　E. the birth of the earth

　　F. the rotation of the earth

　　6. The designers of the VLT are surprised at ___.

　　6. A。分析：借助搭配結(jié)構(gòu)特點(diǎn)：空格處需要名詞性的結(jié)構(gòu)或代詞作介詞at的賓語(yǔ)，所以D肯定不是答案; 利用句子中的核心詞designers of the VLT 和修飾詞surprised作為答案線索，這樣找到答案相關(guān)句：

　　The power of the VLT to see the smallest detail at the furthest distances makes its designers amazed(surprised的近義詞)，判斷A是答案。

　　考點(diǎn)：考察近義詞的替換。

　　C. the location of VLT

　　D. as an example

　　E. the birth of the earth

　　F. the rotation of the earth

　　7. Eta Carinae is taken ___.

　　7. D。分析：可以直接借助常見(jiàn)的搭配結(jié)構(gòu)： take…as…(把…看成是…)判斷D是答案. 也可以利用句子中的核心詞(也是特征詞)作為答案線索, 這樣找到答案相關(guān)內(nèi)容:　Take the case of Eta Carinae，one of the most explosive最容易爆炸的stars in the universe.　“Take the case of …”是“以…為例”, 判斷D是答案.

　　C. the location of VLT

　　E. the birth of the earth

　　F. the rotation of the earth

　　8. Scientists believe the VLT will tell us more about ___.

　　8. E。分析: 有兩個(gè)選項(xiàng)(E和F)提到了“地球”，因此判斷它們中出答案的可能性較大，利用“the earth”作為答案線索，同時(shí)注意句子中出現(xiàn)的比較結(jié)構(gòu)，查找答案相關(guān)句：

　　6 The VLT can detect light that set out on its journey before the earth even existed. 該句中沒(méi)有比較結(jié)構(gòu)出現(xiàn)，所以不看，繼續(xù)看后面的句子：(文章最后一句) One day, we might be able to say we have traveled back to the beginning of time，and we will have a much clearer picture of how our planet (指地球)was born.該句中出現(xiàn)了“地球”，而且也出現(xiàn)了比較級(jí)結(jié)構(gòu)，該句說(shuō)“有一天，我們可以說(shuō)我們已經(jīng)返回到時(shí)間開(kāi)始的時(shí)候，而且我們將對(duì)我們所在的星球是如何誕生的有更加清楚的理解?！?，借助該句判斷E是答案。

　　提示：相關(guān)的選項(xiàng)中往往出答案。

　　文章中的難句和長(zhǎng)句：

　　1. Located 2,600 meters up to the Chilean Andes，it has four huge mirrors，each about the size of a London bus.

　　2. The VLT is so powerful it can spot a burning match 10.000 kilometers away.

　　spot ? see --watch

　　3. It is five times brighter than the sun and when it explodes it is going to be a sight worth waiting for!

　　4. The effects of these past collisions can now be seen by scientists，and astronomers believe the telescope will reveal more about these exciting events in the years to come.
