In the country of Veltria, the past two years' broad economic recession has included a business downturn in the clothing trade, where sales are down by about 7 percent as compared to two years ago. Clothing wholesalers have found, however, that the proportion of credit extended to retailers that was paid off on time fell sharply in the first year of the recession but returned to its prerecession level in the second year. Which of the following, if true, most helps to explain the change between the first and the second year of the recession in the proportion of credit not paid off on time? (A) The total amount of credit extended to retailers by clothing wholesalers increased between the first year of the recession and the second year. (B) Between the first and second years of the recession, clothing retailers in Veltria saw many of their costs, rent and utilities in particular, increase. (C) Of the considerable number of clothing retailers in Veltria who were having financial difficulties before the start of the recession, virtually all were forced to go out of business during its first year. (D) Clothing retailers in Veltria attempted to stimulate sales in the second year of the recession by discounting merchandise. (E) Relatively recession-proof segments of the clothing trade, such as work clothes, did not suffer any decrease in sales during the first year of the recession. 这道题错选了A。 思路如下： 题目问的是为什么在经济不好，衣服卖不动的情况下，第一年零售商还不上钱第二年就能还上了。讲的是零售商还钱的问题。 当时留下的是A,C,D 排除D是因为觉得，即使刺激销售量衣服打折也不能说明能还上钱。可能打折卖1块，纵使家当全卖了也不够。 排除C是因为觉得， 那些本身经济状况就很差的在第一年被淘汰掉以后，剩下的那些没说经济状况如何啊，如果也不咋地，第二年还是得淘汰啊。 A选项当时觉得，即使credit extended，对pay off on time也无太大用处，但最起码跟原文意思接近。所以选了A。

as, since和when的用法区别

看不懂，错选C

正确选项E取非怎么理解（我后来直接加强倒是想懂了）

如何解这两道题呢？

18！能被6整出，但不能被6的N+1次方整除，问n是多少？ 解释说求的18！有8个6的因子，哪八个阿？

原文我读到：不诚实就难达成政治compromise，结论是不诚实可以说明运作良好。 最后我剩下了A和C两个选项，A的意思是“达成Compromise不一定说明运作良好”；C的意思是“选民有其他判断标准”。 当时我的反应是“C中说到选民，跟原文意思关系较近”。 想听听老师的解题思路，以及我思路的问题。 谢谢老师。

原文 我是这么理解的 想让我解释为什么水藻擅长在慢流速水生长但是却在极度干旱的情况下（非常慢的水流速） 死翘翘 。 我觉得ABCDE 都无法解释 这个现象。。 D选项在说 什么在澳大利亚会经历一个完全的干旱然后又恢复。我感觉跟没说一样啊。 不知道是如何解释原文的 还希望老师解答 ^.^
