Math: 大概30%都是JJ的。所以做得很快，提前15分钟就结束。

有一题花了很多时间。最后还是随便选了一个。说side dishes可以有n个(1<= n <= 10). E(n)表示side dishes总共可以有几种。

AWA:

AA: Airline, last year, all the airline industry was suffering from high oil price. And Grovia airline increased new lines to 5 new cities, and although the business expended, G airline still suffered profit loss. However, some of other airlines did improve their profit in spite of high oil price . Thus, the new added airline should be the reason for the profit drop.

AI: The governments should be authorized to withhold any information from public as they wish.

RC:

1.Parasite-host relation.一屏半. 以前JJ有原文，要注意的是最后一段有考点，soil temperature的影响，好像是倒数第三个单词。因为有JJ所以看的很快，没注意，导致回到原文找了三遍才找到。差点就放弃了。

2.文艺复兴时女性地位的看法。

另外两篇，JJ没有。感觉RC做得不好，最后一边只有大半屏。
