考GRE,所以买的。我打算是作为休闲的,增加士气的书使用。
评分很好的书,经典,一系列买下看的,不错不错!
评分速度较快,包装完整,保护的不错。
评分讲的不错,但是注意36淘要在某宝自己买或者网上找资料。36淘题本身也是节选,有时间建议找对应阅读的完整版
评分吾消费京东商城数年,深知各产品琳琅满目。然,唯此宝物与众皆不同,为出淤泥之清莲。使吾为之动容,心驰神往,以至茶饭不思,寝食难安,辗转反侧无法忘怀。于是乎紧衣缩食,凑齐银两,倾吾之所有而能买。东哥之热心、快递员之殷切,无不让人感激涕零,可谓迅雷不及掩耳盗铃儿响叮当仁不让世界充满爱。待打开包裹之时,顿时金光四射,屋内升起七彩祥云,处处皆是祥和之气。吾惊讶之余甚是欣喜若狂,呜呼哀哉!此宝乃是天上物,人间又得几回求!遂沐浴更衣,焚香祷告后与人共赏此宝。人皆赞叹不已,故生此宝物款型及做工,超高性价比之慨,且赞吾独具慧眼与时尚品位。产品介绍果然句句实言,毫无夸大欺瞒之嫌。实乃大家之风范,忠义之商贾。
评分gre核心词汇主机与精炼,同学推荐的
