两个gwd，好像没人问过。

Q13:
Plants are more efficient at acquiring carbon than are fungi, in the form of carbon dioxide, and converting it to energy-rich sugars.

1. Plants are more efficient at acquiring carbon than are fungi
   
2. Plants are more efficient at acquiring carbon than fungi
   
3. Plants are more efficient than fungi at acquiring carbon
   
4. Plants, more efficient than fungi at acquiring carbon
   
5. Plants acquire carbon more efficiently than fungi
   答案是c，为什么a不对呢？（fungi不能用are？）
   Q30:Most insomnia is not an illness or a physical condition so much as a symptom of another problem that may simply be a reaction to certain medications, anxiety about travel, or stress before a job interview.
   
   
   
   1. an illness or a physical condition so much as a symptom of another problem that may simply be a reaction to certain medications
      
   2. an illness or a physical condition so much as symptomatic of another problem that may be a simple one, like a reaction caused by certain medications
      
   3. so much an illness or a physical condition but a symptom of another problem that may be as simple as when certain medications cause a reaction
      
   4. so much an illness or a physical condition, but it is a symptom of another problem, maybe a simple one like certain medications causing a reaction
      
   5. so much an illness or a physical condition but symptomatic of another problem, maybe simply a reaction to certain medications
      答案是E，难道两者之间有比较吗？我觉得A也行啊。
      菜鸟级别，见笑了。

下次最好把两个问题分成两个帖子问，这样比较容易讨论：

Q13：

A 的比较结构错误了，are  应该放在 fungi 后面。

而且将 at acquiring carbon放在 than前 很容易造成歧义：到底是吸收碳的效率高呢？还是吸收真菌的效率高呢？

Q30：

原文的意思是：失眠不太像是我们一般意义上的疾病，而是由其他一些问题所引起的症状：也许只是药物的副作用，或是旅行的焦虑，或是工作面试的压力所引起的。

这里用了一个固定搭配 “not so much .... as ”，意思是：“ 与其说....不如说....”

A选项把an illness or a physical condition放在了not 和 so much  之间，使得句子十分confuse，也不符合惯用语法。

此外，problem后面的that在语法上是定语从句，修饰problem。但逻辑上却需要其修饰insomnia。去掉that，而改用逗号则能解决这个问题。

多谢。语法很烂。
但是fungi应该是可数名词吧，只不过属于单复数变化特殊的哪一类而已。所以我觉得还是可以用are的，当然，are的位置不对。我理解
第二个，你说的“not so much .... as ”，但是后面并没有出现as啊。现在我看看a确实太复杂了。然而e还是不那么convincing。

wkz502

嗯，我百度了一下，fungi的确是可数的，抱歉。

关于E中的as，有一种说法是not so much as 的 as 可以用but来代替：
