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

根据文后未划线部分并列，划线处末尾应为a reaction to …排除BCD（B罗嗦，C中as when中as为代词而非as…as形式，错）

根据句意，是not…but…结构，排除AB

D中it is多余

本题考点：so adj a….固定搭配，而非not so much as   －－－－这个。。对么？

如果对，偶突然转不过弯来了，so much an illness是个类似so clever a boy一个结构么？那much修饰什么呢？我觉得要用much也只能表程度啊  如果把 so clever a boy 这种强调还原，那就是 a clever boy , 那要是把so much an illness还原呢？？

可能是个傻问题，但是转不过来了，或者本身我对这题的理解就有问题，大家指教！！
