概括句意:
A Star Is Born
1 The VLT(Very Large Telescope)is the world's largest telescope(望遠鏡)and is taking astronomers(天文學家)further back to the Big Bang thanthey ever thought possible.Located 2,600 meters up to the Chilean Andes,it has four huge mirrors,each about the size of a Londonbus.The VLT is so powerful it can spot a burning match 10,000 kilometersaway.
2 This astonishing power willallow astronomers to see events in space from the birth of stars to thecollision(碰撞)of galaxies(星系)on the edge of the cosmos(宇宙).The VLT is giving astronomers theirbest-ever view of the cosmos.The power of the VLT to see the smallest detailat the furthest distances makes its designers amazed.
3 Take the case of Eta Carinae,one of the most explosive stars inthe universe.This star produces ultraviolet laser rays(紫外線)and it will destroy itself in afew million years' time.It is five times brighter than the sun and when itexplodes it is going to be a sight worth waiting for!
4 But it is at distances ofmillions,even billions,of light years that the VLT really shows its power.The VLT can detectlight that set out on its journey before the earth even existed.This givesastronomers their first-ever detailed views of events that took place in theearliest days of the cosmos.
5 In other words,the VLT is akind of a time machine.It takes astronomers back to a time when completegalaxies crashed into each other.The effects of these past collisions can nowbe seen by scientists,and astronomers believe the telescope will reveal more about theseexciting events in the years to come.One day,we might be able to say we havetraveled back to the beginning of time,and we will have a much clearer picture ofhow our planet was born.

1.Paragraph 1_________.
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
正確答案:E
答案解析:段落中VLT(大望遠鏡)中反復出現(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B和E,判斷E是答案(VLT是大望遠鏡,段落中也是在強調望遠鏡的“大”(段落中出現(xiàn)了Large,largest,huge),因此判斷E是答案。
2.Paragraph 2_________.
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
正確答案:B
答案解析:段落中VLT(大望遠鏡)和power(能量)反復出現(xiàn),因此這兩個詞是該段主題詞,因此判斷B是答案。
3.Paragraph 3_________.
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
正確答案:C
答案解析:整個段落圍繞Eta Carinae進行介紹: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。
4.Paragraph 4_________.
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
正確答案:A
答案解析:比較被選項:D說“時光機器”,可是該段落提到的儀器是VLT(大望遠鏡),不是“時光機器”,因此D不是答案;A中的狀語結構“before the earth existed”在該段第2句中出現(xiàn)了,該句中沒有提到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“這就使天文學家有史以來第一次觀察到了宇宙早期發(fā)生的事情”,結合這個句意來看A是答案。
5.The VLT will allow scientists to see events _________.
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
正確答案:B
答案解析: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“VLT能使天文學家看見宇宙中最遠地方發(fā)生的最小的事情,這使它的設計者很吃驚!痹摼溟g接的揭示了答案。
6.The designers of the VLT are surprised at _________.
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
正確答案:A
答案解析:借助搭配結構特點:空格處需要名詞性的結構或代詞作介詞at的賓語,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。
7.Eta Carinae is taken _________.
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
正確答案:D
答案解析:可以直接借助常見的搭配結構: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,這樣找到答案相關內容: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.
8.Scientists believe the VLT will tell us more about _________.
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
正確答案:E
答案解析:有兩個選項(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,同時注意句子中出現(xiàn)的比較結構,查找答案相關句: The VLT can detect light that set out on its journey before the earth even existed.該句中沒有比較結構出現(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)了比較級結構,該句說“有一天,我們可以說我們已經(jīng)返回到時間開始的時候,而且我們將對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。
