草滩小恪与英语单词--弱爆的小程序

草滩小恪一直为如何学习英语而苦恼， 特别是单词的记忆。临近考试啦，草滩小恪想恶补一下英语单词， 但是草滩小恪又是very lazy 所以 草滩小恪就找到了草滩大学的历年英语考试卷， 想背一下 阅读 里面出现的高频词汇。草滩小恪认为这idea真TM太机智啦！！！。 但是， 很快草滩小恪就发现， 寻找短文里面的高频词汇真TN的不是人能干的事。那么问题来啦， 咋办呢？ 机智的读者想必早已知道了咋办。 是的， 就是这么办的。

程序说明：

主要功能： 统计一篇英语文章里的高频词汇

附加功能：练习拼写这些高频词汇的一个小游戏。

参数： 建立文本文件file1并保存目的文章。 建立包含你不希望统计的高频词汇（如， is ， am are等）的文本文件file_namol。

好啦， 开始游戏吧！
