GWD3-5-7(火星隕石)

[agk99]

GWD-3-Q5 to GWD-3-Q7:
In 1994, a team of scientists led
by David Mckay began studying the
meteorite ALH84001, which had been
Line discovered in Antarctica in 1984.
(5) Two years later, the McKay team
announced that ALH84001, which
scientists generally agree originated
on Mars, contained compelling evi-
dence that life once existed on Mars.
(10) This evidence includes the discovery
of organic molecules in ALH84001,
the first ever found in Martian rock.
Organic molecules—complex, carbon-
based compounds—form the basis for
(15) Terrestrial life. The organic molecules
found in ALH84001 are polycyclic aro-
matic hydrocarbons, or PAH’s. When
microbes die, their organic material
often decays into PAH’s.
(20) Skepticism about the McKay team’s
claim remains, however. For example,
ALH84001 has been on earth for
13,000 years, suggesting to some
scientists that its PAH’s might have
(25) resulted form terrestrial contamination.
However, McKay’s team has demon-
strated that the concentration of PAH’s
increases as one looks deeper into
ALH84001, contrary to what one would
(30) expect from terrestrial contamination.
The skeptic’s strongest argument,
however, is that processes unrelated
to organic life can easily produce all
the evidence found by McKay’ steam,
(35) including PAH’s. For example, star
formation produces PAH’s. Moreover,
PAH’s frequently appear in other
meteorites, and no one attributes
their presence to life processes.
(40) Yet McKay’s team notes that the
particular combination of PAH’s
in ALH84001 is more similar to the
combinations produced by decaying
organisms than to those originating
form nonbiological processes.
--------------------------------------------------------------------------------
GWD-3-Q5:
The passage asserts which of the following about the claim that ALH84001 originated on Mars?

A. It was initially proposed by the McKay team of scientists.
B. It is not a matter of widespread scientific dispute.
C. It has been questioned by some skeptics of the McKay team’s work.
D. It has been undermined by recent work on PAH’s.
E. It is incompatible with the face that ALH84001 has been on Earth for 13,000 years.

--------------------------------------------------------------------------------
GWD-3-Q6:
The primary purpose of the passage is to

A. describe new ways of studying the possibility that life once existed on Mars
B. revise a theory regarding the existence of life on Mars in light of new evidence
C. reconcile conflicting viewpoints regarding the possibility that life once existed on Mars
D. evaluate a recently proposed argument concerning the origin of ALH84001
E. describe a controversy concerning the significance of evidence from ALH84001
--------------------------------------------------------------------------------
GWD-3-Q7:
The passage suggests that the fact that ALH84001 has been on earth for 13,000 years has been used by some scientists to support which of the following claims about ALH84001?

A. ALH84001 may not have originated on Mars.
B. ALH84001 contains PAH’s that are the result of nonbiological processes.
C. ALH84001 may not have contained PAH’s when it landed on Earth.
D. The organic molecules found in ALH84001 are not PAH’s.
E. The organic molecules found in ALH84001 could not be the result of terrestrial contamination.

這原文讀起來不難，但題目都不好選，想請大家幫幫忙
像是3-5，打死我也想不到是B
3-6 不能選C嗎
3-7 該如何判定

[liwuu]

3-5
從文章中第五行到第九行可以知道ALH84001起源於MARS是普遍被接受的,所以如同答案B所述B. It is not a matter of widespread scientific dispute.再仔細看一下題目所問的內容唷
Two years later, the McKay team announced that ALH84001, which scientists generally agree originated on Mars, contained compelling evidence that life once existed on Mars.

[liwuu]

3-6
小弟覺得文章全文圍繞在於有關ALH84001所代表證據的爭議(如同答案E),相對於答案C將重點放在文章引申出去的火星是否存在生物,答案E感覺比較貼切.全文瀏覽幾遍,全文主旨在於Mckay Team和其他科學家針對ALH84001所做的攻防戰

[liwuu]

3-7
從文章中第20行到25行可以知道科學家舉例說ALH84001在13000前就存在地球了,而PAH的存在則是因為後來落到地球上後所發生的.所以如同答案C,當初ALH84001落到地球時,是沒有PAH的

[kikisky]

大哥~我記得老師好像有說過
at 的文章不會出現 compare 類型的文章
所以3-6考 the primary purpose of the passage...
就不會有C. reconcile conflicting.......這種說法

不知道這種說法對不對????????????????????????????

謝謝各位
了解了

小弟解解看
In 1994(注意時間), a team of scientists led
by David Mckay(注意人物) began studying the
meteorite ALH84001(研究主旨-全文主軸,主旨題要對),(句子已經結束,後面只是補述) which had been
Line discovered in Antarctica in 1984.
(5) Two years later, the McKay team
announced(發表研究成果,要看清楚) that ALH84001, (廢話先跳過)which
scientists generally agree originated
on Mars, contained compelling(strong) evi-
dence that life once existed on Mars.(看完在回去看跳過的在講啥) (哈~居然考一題:大多數都同意)
(10) This evidence includes the discovery
of organic molecules in ALH84001,
the first ever found in Martian rock.(這裡可能考infer:之前都沒證據)
Organic molecules—(破折耗費話跳過)complex, carbon-
based compounds—form(重要動詞) the basis for
(15) Terrestrial life. The organic molecules
found in ALH84001 are polycyclic(poly開頭就是"多") aro-
matic hydrocarbons, or PAH’s(記這個就好). When
microbes die(開始解說成因-看到董為止,必考), their organic material
often decays into PAH’s.
(20) Skepticism(重要反對派出現-看清楚在反對啥,如何反對) about the McKay team’s
claim remains, however. For example,
ALH84001 has been on earth(動詞片語:出土發現) for
13,000 years, suggesting to some
scientists that its PAH’s might have
(25) resulted form terrestrial contamination(兩個字都要背:地表的污染-也就是反對者認為A裡的PAH這種東西是到地球後才加上去的,不是還就有了).
However(語氣轉折意但因是研究者回應,因此仍為正向), McKay’s team has demon-
strated(可考如何回應:用舉証法) that the concentration of PAH’s
increases as one looks deeper into
ALH84001,(越深越多,不可能是地表污染)(後一句廢話重複-跳過) contrary to what one would
(30) expect from terrestrial contamination.
The skeptic’s strongest(最強的懷疑-看清楚會考) argument,(又出來亂)
however(廢話), is that processes unrelated
to organic life can easily produce all
the evidence found by McKay’ steam,
(35) including PAH’s(天哪有3行-不過就是講證據可偽造). For example(已知核心意義即可跳過), star
formation produces PAH’s. Moreover,
PAH’s frequently appear in other
meteorites, and no one attributes
their presence to life processes. (哈~輕鬆掃過四行)
(40) Yet McKay’s team notes(老大出來回應) that the
particular(關鍵字-這次發現的不一樣) combination of PAH’s
in ALH84001 is more similar to the
combinations produced by decaying
organisms(兩個字都要背-腐敗的生物) than to those originating
form nonbiological processes. (可考infer:有PAH不一定是生物)
看文章時就要知道結構,其實粉簡單,研究成果-質疑-回應-再質疑-再回應

GWD-3-Q5:
The passage asserts(表示) which of the following about the claim that ALH84001 originated on Mars?

A. It was initially proposed by the McKay team of scientists. (X,已經出土一萬三千年)
B. It is not a matter of widespread scientific dispute. (沒錯,可是不敢選-長的太不像了)
C. It has been questioned by some skeptics of the McKay team’s work. (沒有,只質疑是地表污染跟偽造)
D. It has been undermined by recent work on PAH’s. (沒有)
E. It is incompatible with the face that ALH84001 has been on Earth for 13,000 years. (沒有,為違背出土一萬三前年的事實)

--------------------------------------------------------------------------------
GWD-3-Q6:
The primary purpose of the passage is to
(看選項前心裡就要有主旨:討論研究發現的可信度)
A. describe new ways(新研究法-沒有,不用再看直接刪) of studying the possibility that life once existed on Mars
B. revise(沒有revise直接刪) a theory regarding the existence of life on Mars in light of new evidence
C. reconcile conflicting viewpoints(沒有conflict point也無從reconcile-刪) regarding the possibility that life once existed on Mars
D. evaluate(並沒有evaluate,只有陳述研究發現跟正反意見) a recently proposed argument concerning the origin of ALH84001
E. describe a controversy(有) concerning the significance of evidence(證據的顯著性就是可信度) from ALH84001
--------------------------------------------------------------------------------
GWD-3-Q7:
The passage suggests that (the fact that廢話不看) ALH84001 has been on earth for 13,000 years has been used by some scientists to support which of the following claims about ALH84001?(回文看一下一萬三千年再幹麻-若有take note則知備用來說可能是地表污染,不需回文)

A. ALH84001 may not have originated on Mars. (錯,大家都信)
B. ALH84001 contains PAH’s that are the result of nonbiological processes. (不是講無生物)
C. ALH84001 may not have contained PAH’s when it landed on Earth. (對)
D. The organic molecules found in ALH84001 are not PAH’s. (錯,是PAH但可能來自地表)
E. The organic molecules found in ALH84001 could not be the result of terrestrial contamination. (錯在not)

回應lowuu戰友
reconcile應該是指將兩方(或以上)意見"融合"成一個結論,而本文只有攻防戰,並沒有reconcile

回應kikisky戰友
compare是比較"如何相同"
就是疊起來看是不是全部一樣
看雙胞胎就是
是真的沒出現過
但印象裡好像有看過compare對的
應該不是考主旨
記得有講到"差異"
可能是compare the difference

[liwuu]

Dear大衛...
我的意思就是指全文主旨在於Mckay Team和其他科學家針對ALH84001所做的攻防戰...同意沒有reconcile!!

ps.推一下這麼詳細的解題過程...看來AT在你手中應該穩死了!!

版大~
我不太懂你說的(ㄛ~不要誤會~是我中文程度不好的關係~)
不過
compare的確會出現在 對 的選項中

是在 寫作技巧 的題型裡

而非main idea的題型裡
所以我才會醬說

另外
不要叫人家戰友啦~人家已經脫離at苦海粉久了~不想再回頭了~ :P

[davidlee0222]

回應kikisky
不稱戰友
那稱同窗好了...
compare跟contrast反意
知道contrast是在比"不同"
compare是在比相同
就像看雙胞胎一樣
記得是跟juxtapose"併列"同意

回應liwuu
哈哈　　　見笑~

在這看到大衛實在很感動...
這樣的分析是大陸的牛牛也比不上的啊

GWD-3-Q6:
C. reconcile conflicting viewpoints(沒有conflict point也無從reconcile-刪) regarding the possibility that life once existed on Mars

想請問一下，第二段不是確確實實有提到conflicting viewpoints
(就是McKay和其他持反對觀點的scientists各自的觀點)，而且作
者的確是先描述那些scientists的反對觀點，再提出McKay的觀點
來反駁，這樣的動作，不算是reconcile嗎?還是我對reconcile這個
字的含義誤解了呀
煩請板友大大們解惑囉^^~~~3Q

compare/reconcile 比較事物的"相同"點
contrast/distinguish 比較事物的"不同"點
二段中兩方各持己見，無共同點的產生，所以用reconcile這字眼是錯誤的。

GWD-3-Q6:
C. reconcile conflicting viewpoints regarding the possibility that life once existed on Mars


除了reconcile的錯誤, 小弟再提供另一種想法, 不知道對不對
用OG11的觀點, 本文呈現導致火星上有生物的evidence這個過程有攻防戰, 並非火星生物曾經存在的 "可能性", AT考法中, verbal三個部分都有的就是對於比較關係中的元素相當重視, 也就是說被拿來比較的個體是甚麼,通常會是考點
