拿微软的英库做博士英语作业太爽了

      今天是博士英语作业的deadline,一大早爬起来做作业,发现好难,前不久周明博士来系里作报告推荐了英库,用了一把,作业20分钟就搞定了,英库真是天才。

      作业如下,这里不表,先说说几个好用的功能。

      (1)选择追加形容词搭配

              比如第三题,我想知道option有哪些前缀形容词可以修饰,就用【adj. option】搜索,结果很满意。

      (2)选择合适的名词

              比如第七题,我想知道享受特权,这个特权怎么说,就用【enjoy 特权】搜索,结果依然很满意。

 

      不过还是有些不尽如人意的地方,当然人家做这个不是为了给我做作业,但还是有些功能挺实用的,比如

      我想搜索The moon can be said to be like a large mirror 中间be said to be like可以替换成什么,如果可以搜索 

      【The moon can{}a large mirror.】就好了,可以让检索引擎自动提供{}中可能出现的短语。

      这个功能在写论文的时候,很实用。
