今日练习题为语法题，题目如下
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 an illness or a physical condition so much as a symptom of another problem that may simply be a reaction to certain medications
B 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
C 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
D 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
E so much an illness or a physical condition but symptomatic of another problem, maybe simply a reaction to certain medications
正确答案：
A
题目解析：
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)
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)。 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。
