[求助]og9的一句話

gigiga0118

However, it is important to note that other factors,

(45) such as volcanic particulates or variations in the amount

of sunlight received by the Earth, could potentially have

affected the climate. The advantage of the Milankovitch

theory is that it is testable: changes in the Earth’s orbit

can be calculated and dated by applying Newton’s laws

(50) of gravity to progressively earlier configurations of the

bodies in the solar system. Yet the lack of information

about other possible factors affecting global climate does

not make them unimportant.

關於這句話,我反覆的讀

順不太起來

1.作者的態度到底是什麼??

開頭出現了yet(轉折詞)

後來又有not.....unimportant

不明白阿

2中間那個them是指代什麼東西??

是指Milankovitch和Newton定律的運用嗎???

還是factors???

暈阿

1/not unimportant= important.

2/我认为指changes.

這段一開始提到了

1However,還有其他因素也需要注意

(作者態度轉變,對M的理論轉向負面)

2後來又出現the advantge

(作者態度再轉變,變成支持M的理論)

3最後有yet出現,Yet the lack of information

about other possible factors affecting global climate does

not make them unimportant.

缺乏其他資訊關於影響氣候的因素,使的改變變的重要???

(作者的態度又轉回了負面)

還是不懂最後一段的層次關係

然後作者對M理論的態度

解释中有一些对文章总体架构的分析，供参考：

49

D is the best answer.

In the first paragraph, the author describes Milankovitch”s theory and explains why the theory previously had been considered untestable. In the second and third paragraphs, the author describes a scientific break-through that has made it possible to test and provide support for Milankovitch’s theory. Although the author also mentions other factors that potentially could have affected the Earth’s climate, the passage as a whole is concerned primarily with Milankovitch’s theory and the scientific method that has been used to test that theory.

A, C and E do not accurately reflect the content of the passage. Although the passage does describe a new research method supports rather than casts doubt on Milankovitch’s theory.

50.

D is the best answer.

In lines 9-16, the author states that a recent discovery has made it possible to establish a precise chronology of the Earth’s ice ages. Scientists have used this discovery to test the basic premise of Milankovitch’s theory—that the ice ages were caused by variations in the Earth’s orbit around the Sun. The author notes in lines 53-56 that the data have established a “strong connection” between orbital variation and ice ages, which confirms the plausibility of Milankovitch’s theory. However, one can infer from the last paragraph that the author believes factors other than variations in the Earth’s orbit could provide plausible explanations for global climate change.

我觉得你说最后一段第1、2句有意思的转折，我同意。但是第3句仍是在支持第2句的内容，没有再发生转折了。从全文来看，这一段是在进行qualification.即，先做了个让步，然后，继而认可所让步的内容并没有使M所强调的地球轨道变动的重要性降低，从而再度支持了M理论。

理解了...

可是一般來說,看到轉折字,就會出現態度或內容上的不同

這邊第3個轉折字yet的出現讓我誤以為作者對M的理論持有負面態度

所以,不是轉折字出現,就一定表示態度改變囉??

是不是一切還是以上下文而定

嗯，是啊，转折词是个标志，具体的意思要稍稍把握一下才好。阅读关键在于文意的理解。

我觉得这个yet的理解关键在于them的指代，很显然在them指代changes的时候，完全可以很容易得出50题的答案是D而不是E。只是这个them的指代实在很难弄清楚，必须弄清楚原文整个论述过程才能判断出来。

另外，yet并不总表转折，我更认为这里的yet只是副词表递进可以译作“另外”的意思，而不是连词表“然而”的意思。
