5*6*1=2*3*5=30
7+2+1=……=2+3+5=10

原文是unrefine A错 oa少=a少 推出质量高

，with widespread swelling and stiffness immobilizing the injured area是一个独立主格结构 ，with独立主格结构

关于E选项为什么错
①it's wrong, because "until healing" would apply to the subject "swelling and stiffness". those don't heal; the injured area does.
②instead出现很多余 因为unlike就表示的这个意思

就算选E appear也应该是appears

反对的是计划 而不是目标

去掉B中的its 对吗？

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。

for doing表示已经发生过的事情（原因），而to do表示还未发生的事情（目的）

A is to B what C is to B

these foreshocks indicate nothing about the magnitude of an impending quake and are indistinguishable from other minor tremors that occur without large earthquakes.
