GWD6-Q5 to Q7: (生物類)
According to a theory advanced
by researcher Paul Martin, the wave
of species extinctions that occurred
in North America about 11,000 years
(5) ago, at the end of the Pleistocene era,
can be directly attributed to the arrival
of humans, i.e., the Paleoindians, who
were ancestors of modern Native
Americans. (PM先生認為動物的消滅都是人類的祖先幹的) However, anthropologist
(10) Shepard Krech points out that large
animal species vanished even in areas
where there is no evidence to demon-
strate that Paleoindians hunted them. (SK先生則認為沒有證據支持是人幹的)
Nor were extinctions confined to large
(15) animals: small animals, plants, and
insects disappeared, presumably not
all through human consumption. (同時小動物的滅絕也不能記在人類頭上)Krech
also contradicts Martin’s exclusion of
climatic change as an explanation by
(20) asserting that widespread climatic
change did indeed occur at the end of
the Pleistocene. (SK同時認為PM沒有提到天氣的變化相當有問題)Still, Krech attributes
secondary if not primary responsibility
for the extinctions to the Paleoindians,
(25) arguing that humans have produced
local extinctions elsewhere. But,
according to historian Richard White,
even the attribution of secondary
responsibility may not be supported
(30) by the evidence. (RW先生則是認為,即便是SK的看法也缺少證據)
White observes that
Martin’s thesis depends on coinciding
dates for the arrival of humans and the
decline of large animal species, and
Krech, though aware that the dates
(35) are controversial, does not challenge
them; (PW先生認為,PM的看法其實只是巧合)
yet recent archaeological
discoveries are providing evidence
that the date of human arrival was
much earlier than 11,000 years ago. (第四種看法,意味支持「動物的滅絕確實不是人幹的」,也就是同意PW的看法)--------------------------------------------------------------------------------
Q5:
Which of the following is true about Martin’s theory, as that theory is described in the passage?
A. It assumes that the Paleoindians were primarily dependent on hunting for survival. 題目沒那麼直接說,只說人要負責,並非直接說是被人宰來吃
B. It denies that the Pleistocene species extinctions were caused by climate change. 從SK的看法就能推出
C. It uses as evidence the fact that humans have produced local extinctions in other situations. 是SK不是PM
D. It attempts to address the controversy over the date of human arrival in North America. 並沒有
E. It admits the possibility that factors other than the arrival of humans played a role in the Pleistocene extinctions. 並沒有
--------------------------------------------------------------------------------
Q6:
Which of the following, if true, would most weaken Krech’s objections to Martin’s theory?
A. Further studies showing that the climatic change that occurred at the end of the Pleistocene era was even more severe and widespread than was previously believed 是support
B. New discoveries indicating that Paleoindians made use of the small animals, plants, and insects that became extinct SK認為不是人幹的,這裡卻發現有人吃動物,直接weaken了SK
C. Additional evidence indicating that widespread climatic change occurred not only at the end of the Pleistocene era but also in previous and subsequent eras 要是天氣不好是持續的,則就不能歸因於天氣,要死早死了
D. Researchers’ discoveries that many more species became extinct in North America at the end of the Pleistocene era than was previously believed 無關
E. New discoveries establishing that both the arrival of humans in North America and the wave of Pleistocene extinctions took place much earlier than 11,000 years ago 無關
--------------------------------------------------------------------------------
Q7:
In the last sentence of the passage, the author refers to “recent archaeological discoveries” (lines 36-37) most probably in order to
A. refute White’s suggestion that neither Maritn nor Krech adequately account for Paleoindians’ contributions to the Pleistocene extinctions 支持才對不是refute
B. cast doubt on the possibility that a more definitive theory regarding the causes of the Pleistocene extinctions may be forthcoming 沒有提及
C. suggest that Martin’s, Krech’s, and White’s theories regarding the Pleistocene extinctions are all open to question 有結論才對,不會沒結論
D. call attention to the most controversial aspect of all the current theories regarding the Pleistocene extinctions 不只是注意而己,而是更積極的起了否定PM與SK的作用
E. provide support for White’s questioning of both Martin’s and Krech’s positions regarding the role of Paleoindians in the Pleistocene extinctions這裡提到的證據,剛好直接證明RW先生對另兩位科學家的觀察
