13. r,s,t are positive integers. Is t/s^2 an integer? (1) t/(rs) is an integer. (2) r/s is an integer (C)

14. a, b are nonnegative numbers and (a-b)/(a+b)=1/2, which one of the following must be true? (Choice C: a>b)

15. Is there any change of the percentage of the number of workers …….？ (后面记不太请了， 但不影响理解) （1）the percent of workers of … in 1991 is 67% (2) the percent of number of workers of … in 1997 is 73％ （其中数字不准，可是这道题关键的叙述就是这样，如有不妥请补充，但这道题是我唯一一道不确定的，紧供大家讨论）

Verbal: 因为我得成绩，就不再写机井误导大家了，免得和我一样。不过这次的经验也许有用。前两题是语法，不难，第三题是一片阅读，40行，三个问题。之后是逻辑。从这样的搭配来看前面的题做的不是很差。 我得问题出在11－20题，很明显，连续三个是语法，证明前两个联错了，之后又是三个逻辑，证明前两个又出问题。由于过分担心逻辑，耗时太多，以致后面放掉最后一个阅读。借此，请即将上考场的G友注意我得经验，如果有用的话。
