TTGWD2-30还是不明白A错在哪,谢谢拉

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

还是不明白A错在哪,谢谢拉

我觉得很多答案存在问题

not so much sth as sth 不是......而是......（此为固定搭配短语，
            参见《高级牛津英汉双解词典》）She is not so much as poor as careless with money. 她倒不是穷而是太不在乎钱了。（词典上的例句）

本题答案应为A。

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.

A. 只不过为了行文方便，便于理解和起到强调作用以便更加明晰句子的意思，将“an illness or a physical condition" 放到了"so much"之前。“正常”的行文应为Most insomnia is not so much an illness or a physical condition as a symptom of another problem that may simply be a reaction to certain medications, anxiety about travel, or stress before a job interview. A选项为完美选项，无任何错误。an illness or a physical condition 与 a symptom of another problem 完美对称。该句的译文为：大多数失眠不是疾病或身理（物理）疾病，而是由于某些药物的反应、旅途的焦虑或工作面试的紧张而产生的一种症状。

B. an illness or a physical condition 与 symptomatic of another problme 不对称；逗号后有谓语动词，但前无连词。

C. not so much but 没有这样的词组（用法）； that may be as simple as when certain medications cause a reaction 不合语法。
                

D. not so much ... but, 没有这样的词组（用法）；逗号后有谓语动词like, 但maybe为副词，不能连接句子。
                

E. not so much but 没有这样的词组（用法）。（有于很多人选E,我多说几句） E选项如用not...but...结构，so much 多余，且an illness or a physical condition 与 symptomatic of another problem 不对称。

该句主要的问题是没弄清词组 not so much sth as sth 的用法所致，所以多查词典对我们学习很有帮助。
                

简单的突破法。SO MUCH 作比较后面要加AS。CDE排除

B中LIKE举例，不好（做“像”讲也不好）。
