12 我本来也选了C，看了讨论之后还是觉得B最好！

should问一下should这一句怎么理解,倒装还是什么??

should = if    [modal verb] formal use this when something might happen in the future but it is not likely

- We've planned everything very carefully, but should there be any problems, contact me immediately.

- Should you ever find yourself in Oxford, I'm sure Uncle Eric would be glad to see you.

哈 终于有人跟我问一样的问题   

建议你 单字问题 查字典比较快

12 (C) provide a standard of comparison against which the impact of human activity on the gene flow among salmon populations should be measured

请问C中 which 指代什么?

谢谢

我觉得是standard

measure somebody/something against somebody/something phrasal verb
to judge someone or something by comparing them with another person or thing
Bridget did not think she had to measure herself against some ideal standard.

Measured against our budget last year, $2.7 million seems small.

第12题我选C。

文章第一段第一句就说了"Over the last 150 years, large stretches of salmon habitat have bben eliminated by human activity  ...However, habitat loss also has the potential to reduce genetic diversity.  This is most evident in cases where it results in the extinction of entire salmon populations. 我觉得这就是主题句，强调两种因素，人为及自然的对照。

再看第三段第一句，Although no one has quantified changes in the rate of straying as a result of the disturbances caused by human, there is no reason to suspect that the effect would be qualitatively different than what was seen in the aftermath of the Mount Saint Helens eruption."。 简而言之，既然人为因素的影响没有量化，也就没有理由来怀疑自然因素造成的后果有质的区别。

C选项中的standard of comparison 就是“ ... qualitatively different than what was seen in the aftermath ...” than 之后的东西。

请指教！

討論看了半天, 還是要自己拿主意選答案囉!!

关于12题, 答案应该是B

B强调的是对基因genetic diversity的影响

D强调的是对数量population的影响

本文首先提到的是人类活动对数量的影响, 又提出对基因的影响. 从对基因的影响提出了stray这个概念. 之后解释stray, 解释人类活动如何影响stray, 但都是基于基因的多样性受影响而发起的讨论. 相反的, 对于population的讨论淡化了. 所有的讨论是围绕着基因多样性不足展开的, 而stray是直接原因.

因此, the aftermath of the Mount Saint Helens eruption 不可能跳到文章一开始去修饰强调已经不是文章中心的population.

请指正.

我本来被你说服了
后来发现了B一个重要的陷阱："EXTEND"+"genetic structure"

自细读B，他说aftermath of the eruption提给了一个程度指标。
后面的修饰语加入一读，那个"程度指标"是在"genetic structure"方面
也就是说，eruption的结果造成了genetic structure改变到一个程度，那个程度是人类也可能造成的。
但63行仅指出eruption将鱼回流时的走失率由16%提高到40%>>至于对genetic structure的影响到什么程度，完全没有提到。

所以B非常狡猾，等于自行加入了 "影响走失率的程度" 就是 "影响genetic structure的程度" 的前提。>>ETS标准的跳跃思考的混淆选项!!!!!

C正确

要求nn来解决问题

我现在是觉得b也有道理是，c也有道理
