难理解的句子，来源于阅读，听力。通常是长难句难理解，但是有时也会因为极其exactly的用词，culture disparity等因素而难以理解，所以有必要accumulate。
听力的句子读起来并不难理解，可是听起来就不一样了，尤其平时听的少的。尤其一些习惯的倒装和clause，听起来会容易跟不上，尤其很狗的考试会在这种地方突然speed up，你就懵逼吧。
还有名人名言也插进来了，idiom也挑精髓一点的，不是人云亦云的加进来好了。
英语，跟练肌肉这些东西一样，不是一日之功，你学个几天，跟几天前的你自己，差别不大。尤其还是处在用不到的语言环境下，没个考试根本不会去碰，更别谈什么积累了，都是临时抱佛脚，学的都是哑巴英语。
现在机器翻译基本问题不大，机器作文更是秒杀大多人，唯一还难替代的就是听说，奈何这还是大多人的软肋。所以学了这么多年英文为了什么，都是国家的牺牲品。
更可气的是，生活英语，侧重俚语和名词。哭晕了吧？
最后，终身学习，这一点知易行难。
