The conveniences that Americans desire reflect not so much a leisurely lifestyle as busy lifestyle in which even minutes of time is too valuable to be wasted.

1）如何翻译这句话？

2）上句中 not so much a leisurely lifestyle as busy lifestyle 很难理解，看不懂什么意思？

      看到not so much...as...是什么用法，什么意思呢？

3）可以说not so much...as... = not as much...as...吗？一样吗？

4) 上述的3)中，much究竟是什么成分？为什么会出现在not so...as中呢？以前学过的比较级不就是as...as吗？
