题目分析：
略。
选项分析：
A选项：比较对象不对等。本题想比较的不是两个年份，而是两个年份的价格。检查本选项最合理的比较对象可知，我们真正应该比较的是“现在的价格”和“一年前的价格”。如果只用now，相当于比较的是“一年前的情况”和“现在的情况”，这是不对的。因为“价格的情况”和“价格”是不同的，只有价格才能higher（高低），价格的其它情况或者属性是没有高低之分的。
B选项：Correct. 本选项在逻辑和语法上均是正确的。
C选项：比较对象错误同(A)。
D选项：higher+than是习惯表达，不能加as。
E选项：本选项错误同(D)。
比较对象没问题的。 比较状语从句是完整的句子，所以A选项than右边是a year ago，把主谓补充完整就是Prices at the producer level are only 1.3 percent higher now than prices at the producer level are a year ago. 完全没问题。 A选项错误是后半句 are hurting and therefore raised。两个动作hurt跟raise之间如果没有明显的时间状语的改变，时态就要一致。 逻辑上来说，洪水干旱一直伤害着农作物，所以（and therefore）价格上升停止了（raised过去式表示已经结束），逻辑说不通。
