bluestone1 gg终于公布了答案，偶错的惨不忍睹，不过也罢了，考期将至，没有时间深究了，那位高人将答案评说一下。

5 我在A 和 C之间犹豫了半天，A可能的问题是 a circumstance ， C可能的问题我觉得是which
和it的指代，最后我决定选A。如果which是指代monkfish那后面的its又是指代什么的 .
所以我仍然的认为应该选A

39 偶觉得B没有错误，species是单复同形的，而且和clones也很好的对应。
偶觉得members对应不如B好
为啥选E呢？

31. Because they can reproduce several times each year and produce large numbers of offspring, many insect species can generally adapt quickly to changes in their environment.
A) Because they can reproduce several times each year and produce large numbers of offspring, many insect species
B) Because of many insect species’ ability of reproducing several times a year, along with producing large number of offspring, thus they
C) Because they can reproduce yearly several times, along with producing offspring in large numbers, so many insect species
D) Due to their capability to reproduce several times yearly and to produce large numbers of offspring, many insect species
E) Due to their ability of reproducing several times yearly and to produce offspring of large numbers, many insect species

31为什么会选E，due to 是介词，后面的to produce offspring of large numbers部分是
隶属于ability的，我觉得这个结构很奇怪ability of ... and to ...，另外 produce offspring
of large numbers，我觉得没有 produce large numbers of offspring好，我觉得重点
应该落在large numbers上，而不是offspring上。

另外A中的each year和yearly，我刚刚查了一下郎文和韦氏，确认了一下

each: being one of two or more distinct individuals having a similar relation and often
constituting an aggregate (韦氏)
each is used for any number of people or things taken separetely (郎文)

所以或者可以理解为用在这里不好

A还为什么错，because/due to; can的重复？

请教！

谢谢 solome mm 将题目贴在一起，我把自己做错的题敲一题、贴一题，所以没整理

5. 我也选得 A, 但 there are no xxx, as there are 这种用法确实可能有问题，见 OG 91
但给的答案 C 中，which 指代全句，应该更错。？？？

13. 给的答案 C 中的 amount 也好像有问题

27. 给的答案 B 中的 which 的指代也好像有问题

31. 给的答案 E 中的 ability of reproducing 也好像有问题

34. 给的答案 A 中的 when 也好像分不清指从句中 known 的时间还是 made 的时间

39. 给的答案 E , 我倒想通了

请大牛指点

作者: solome 时间: 2003-12-10 23:50
39 的E 是怎么回事呢？

作者: bluestone1 时间: 2003-12-11 00:31
39.  中 clones 表示个体（有 one another 为证），与 members 都是复数且对应
   A 中them 无指代对象
   B 中 species 是单数，且与 clones 无法对应
   C 、D中 homogeneity 更clones 无法对应

   但 E 中的两个 their 是否有问题，请NN 们发言

一点愚见，抛砖引玉。同意bluestone 5，13，27，39 的答案。
31题我选D
B: Because ... thus  错
34. Scientists have dated sharp-edged flakes of stone found in the fine-grained sediments of a dry riverbed in the Afar region of Ethiopia to between 2.52 and 2.60 million years ago, pushing back by more than 150,000 years the earliest date when it is known that humans made stone tools.

B.at which it is known that humans had made
C.at which humans are known to have made
D. that humans are known to be making
E . of humans who were known to make

C: because ... so    错
E: ability of doing    错 OG 117 明确指出这种用法 unidiomatic ，还有，即使无此错误，and 连接的两部分应该平行对应，不应该分词和不定时同时出现；另外，produce offspring of large numbers 用法也有问题，这里应强调 large numbers
比较容易迷糊的选项是 A，单从语法角度讲， A不错，但从意思上分析，（尤其和 D 比较），D 优。这里讲由于昆虫具备某些能力，所以才如何如何。而 A 的意思是应为他们能做甲和乙，因此如何如何。逻辑意思有差距。

对于 D，大家可能对 capability to 的用法有怀疑，我查了牛津字典，capability to do sth和  capability of doing sth 均可。另外，OG 87 题，就有 capability to 的用法。
在此题中， their capability to reproduce  and to produce  完美搭配，yearly 也好过each year
因此， D 最佳。

B.at which it is known that humans had made
C.at which humans are known to have made
D. that humans are known to be making
E . of humans who were known to make

我选C
A: it指代不清，这里 it 应该指代that humans made stone tools，但意思不通；
B: 同 A 犯一样的错误；
D: that  和不定式的进行时的用法不对；
E: 重心不对，这里 date 是指人造工具这件事发生的时间，而非特定的人的时间，他们被知道造了工具。
C 中，which 指代 date，说明在这个时间发生了什么事。the Key!

请大牛们指点批评！
