我先做的第一题 一开始错选了A 答案选B those代指price 实际上比较的是price of now和price of 1year ago比较
然后做到第二题的时候 错选了E 我认为应该和前面那道题一样也是两个不同时间的price在比较 但是这道题选A 表示比较的是两个时间

有点混乱了 为什么第一个句子比较的就是不同时间的price 第二个句子比较的就是不同时间呢 求帮忙指点一下 感谢！

唉。。我也感觉比较结构特别混乱

GMAT400

第一题整个句子的主语是Prices at the producer, 简单的主系表结构，在than之前没有任何定语和状语的修饰，所以对比只能够比较主语prices
而第二题在than之前是有明确的时间状语的，所以than比较的是时间状语。另外第二题的E选项 rise和higher重复..

感觉用RON 的方法看就可以解决了呢
比较结构也是一种平行，平行的话就先看关键词右边的。第一道题A than右边是a year ago,但是在左边找不到对应的平行啊
B的话 those of a year ago，就有price平行来比较了
第二题的话 than右边就是last 左边就有this year 平行
我是这样理解的，错了的话请指教~~
