OG-29-Q-180

谢谢WANGYU 版版，我还是不要太钻牛角尖的好，：）

180。在两类说的学者对prokaryote并不分true bacteria和 archeateria。所以他说prokaryote就是说true bacteria，后面的原文一致。我明白OG的解释，它是说prokaryote还有一种archebateria,这些不form a coherent group所以排除该选项。可这不正搬石头砸自己脚吗？

以下是引用fair_sword在2004-7-6 16:46:00的发言：

180, the question asks which  of the following is consided by researchers working under the two-category hypothesis as correct.  the researchers never mention anything about the coherent group.  the materials that related coherent is developed by some techniques.

If this question asks which of the follwing is correct according to the passage, then the choice you mentioned is correct.

可能唯一的解释也只能是上面fair_sword说的了，两类说学者没有研究过coherent group 的问题。不知这样理解是否正确，不过和OG 的解释不同。

177. According to the passage, which of the following statements about the two-category hypothesis is likely to be

true?

(A) It is promising because it explains the presence of true bacteria-like organisms such as organelles in

eukaryotic cells.

(B) It is promising because it explains why eukaryotic cells, unlike prokaryotic cells, tend to form multicellular

organisms.

(C) It is flawed because it fails to account for the great variety among eukaryotic organisms.

(D) It is flawed because it fails to account for the similarity between prokaryotes and eukaryotes.

(E) It is flawed because it fails to recognize an important distinction among prokaryotes.

怎么找到定位，og揭示的定位30-31并为说道二分发呀？ 18行道提到了similiarity . confused

sorry, i made a stupid mistake in lastest question. skip it.

明白了，谢谢FAIRSWORD斑竹。这题出的够损的。

tony 6 错了。因为proXXX里面存在第三种生命，所以不是coherent group.见og解释

我觉得fair_sword这样解释180不选A的理由是因为hypothesis定位这个说法不太让人信服啊

OG解释说A错误的原因在于prokaryotes还包括one respect也就是有新的分支：archaebacteria。

原文6行说：true bacteria are prokaryotic cells并不能说明prokaryotes就等同于true bacteria啊，从某种程度上，prokaryotes 应该是包括true bacteria的。所以180题中A说prokaryotes form a coherent group 是不对的，如果说true bacteria 就对了，这就是为什么181题对A的解释说：Lines 37-38 supported the idea of "true bacteria indeed for a large coherent group" of the kind postulated by the two-category hypothesis，从红字划线部分可见OG 是同意true bacteria form a coherent group这个是two-category hypothesis的观点的

还是有些晕，这题180题反正开始我是做错了

还是同意hncsxj斑竹的说法

文中30-31的三分法得出的结果揭示了19-20二分法的错误。

181. All of the following statements are supported by the passage EXCEPT:

(A)  True bacteria form a distinct evolutionary group.

(B)   Archaebacteria are prokaryotes that resemble true bacteria.

(C)   True bacteria and eukaryotes employ similar types of genetic coding.

(D)  True bacteria and eukaryotes are distinguishable at the subcellular level. (E)

(E)   Amino acid sequences of enzymes are uniform for eukaryotic and prokaryotic organisms.

原文：其中涉及到e选项的部分：

But even where the molecular processes are the same, the details in

(15) the two forms are different and characteristic of the respec-

tive forms. For example, the amino acid sequences of vari-

ous enzymes tend to be typically prokaryotic or eukaryotic

我觉得可能没有看懂原文的意思，我觉得就是e选项阿，为什么og说contradict?
