as much....as....  连接的两部分是不是要严格对称呢,可以并列两个句子吗?

as much as这样的机构又有什么差异呢

eg:

Retailers reported moderate gains in their November sales, as much because of their sales of a year earlier being so bad as that shoppers were getting a head start on buying their holiday gifts.

1. of their sales of a year earlier being so bad as that
2. of their sales a year earlier having been as bad as because
3. of their sales a year earlier being as bad as because
4. their sales a year earlier had been so bad as because
5. their sales of a year earlier were as bad as that

要对称的，和than表比较可以对比来看，这是个很重要的考点！比较的对象一定要形

式对称，概念对等.
