数学狗三只，作文狗一只～

刚考完，回报CD，放几只记得的狗，祝大家都取得好成绩。

数学：
以下哪个选项满足 -|3x^2-2|/[(4x^2-5x)-(3-2x)^2]>0。
选项中有三个里含有x与5/4，3/2的大小关系的，另外两个分别是-9/7<x<9/7和x<9/7。题干没错，就是求分母什么条件下小于0。

另外碰见了42题，不过条件稍微不一样，我碰见的是：
walker和jogger往喷泉走，walker速度为6mile/h,jogger速度为10mile/h，jogger在passing walker10分钟后到达喷泉，求jogger走到喷泉处所用时间。答案有1，3+2/3，12，15，16+2/3

刚刚又想起来一只数学狗：
一个square table 的周长是120inch， 另有一个长方形table的长和这个square table一样，宽是square table的一半，求多少个边长为3inch的square能完全cover这个长方形。先求出长方形面积，再除以边长为3inch的square的面积。


IR和Verbal就不放了。

作文：
biotech industry is a rapidly growing industry and new biotech companies are good for the economies of the towns they based. However, the biotech industry  needs high skilled workforce and state of the art lab space with most advanced technologies. In neighbor university town Martinton,some university graduates set a successful biotech lab,but the government of Martinton closed the lab. Martinton's short sightseeing close of the lab will benefit the town of Zaneville. Thus, "somebody"said that Zaneville should give financial support to biotech labs since those labs will contribute to the economy of Zaneville. 意思就是这样。
