靠,这题我都做过,Carol的年龄正好跟他爸是数字反着的.个位和十位之和是10.
咱们讨论一下.可能有如下几种,
Carol19他爸91
Carol28他爸82
Carol37他爸73
Carol46他爸64
Carol55他爸55. ⊙﹏⊙b汗
显然从常识上讲只有Carol37他爸73 和 Carol46他爸64 两种情况 符合情理一点吧.当时我看到这题也挺乐的,我还想他爸是26岁生的他还是18岁生的?我当时忘记我怎么做对了,貌似当时选项能排除.
发展商的土地的湖泊临街有X尺.成若干块,每块有80尺或100尺湖岸.若1/9的地块每块有80尺湖岸,而剩下的40块地每块有100尺湖岸,那么x是多少?
回答：4400
1/9的土地是80尺 剩下40块占了全部块数8/9 也就是一共有45块地 40块是100尺的 5块是80尺的!总共多少呢?40*100+5*80=4400
然后给你介绍一下数学复习吧.我跟你说没别的,就是 大白本（知道大白本吧?GRE那个题库） 掐时间做!你别看简单,你试试半小时做完正确率多少!我第一次30分钟做完错了8道.当时就崩溃了.数学尽可能得满分,但是真不像新东方老师说的不是满分就不是中国人.我和我身边的好多人都没满分.但是你要是数学下750那就太亏了,申请会受影响!
一定要每天都恰时间做大白本.掐时间太重要了,你稀稀拉拉做感受不到时间紧读不清题的压力.
还有一个我想说的,好多人的误区,其实GRE并不是最重要的,从我申请的经历我认为托福比GRE重要.GRE过线不卡,托福决定发offer的顺序!
