问题描述：
高人请解答几道SAT的语法题
1、普林斯顿上的
thanks to the rapid growth of the internet,the internet service provider 【gained 】three million subscribes by 1996 and by 1996,was gaining as many as a thousand new customers each week.
这道题错的地方是Gained,我可以理解 但是后面的and by 1996怎么和前面的重了 而且was gaining 为什么这样用呢 be doing用在这里对么?
2、because his experience in the navy medical corps had been rewarding,Bob applied to medical school after hew was discharged from the navy.
这句话是没有错的,但是我觉得rewarding 是不是应该或者可以改成rewarded 呢 就是之前的经历是被奖赏过的 我知道rewarding可以 那么如果是rewarded是对的么?
