GRE Issue 写作 的考场实战中，广大考生的首要痛点之一就是感觉时间非常紧迫： 要么面对一道很尬聊的题无从下手，比如像面对第146原题“无聊虽然伴随着自我满足，但是它会导致尴尬”， 稍微有些思路的时候一晃眼七八分钟已经过去。 要么强迫症爆发，非要在记忆宫殿中挤出来一个高大上的事例，并且逐字逐句精雕细琢，结果时间一到，连半个屏幕都没有写满。 面对这个痛点，我的原则是，实战至上，拒绝花拳绣腿，希望能够帮助大家剔除任何拖沓实战速度的累赘。 提速之前，点题是3分上下的分水岭。 有些题目设计得很微妙狡猾，如果想当然地发挥没有缜密地钻透彻题目真正的用意，那么往往会导致如下现象：考完试自我感觉极为良好，但是分数一出来却很低。 比如第55原题： The main benefit of the study of history is to dispel the illusion that people living now are significantly different from people who lived in earlier times. 这道题有的同学会讨论我们为什么和以前的人们不一样，因为科技在不断颠覆，为什么又一样，因为我们的基因没那么突变，所以我们的激素，欲望，动机还是和古人一样。 以上的思路足够能让考生自我感觉良好，但是实际上却跑题了

One advantage of Reason ML over JavaScript is that it provides a Map type that uses structural equality rather than reference equality. However, I cannot find usage examples of this. For example, how would I declare a type scores that is a map of strings to integers? /* Something like this */ type scores = Map<string, int>; And how would I construct an instance? /* Something like this */ let myMap = scores(); let myMap2 = myMap.set('x', 100); The standard library Map is actually quite unique in the programming language world in that it is a module functor which you must use to construct a map
