我昨晚在知乎搜了一下“收益”，你知道的，我的原意是想搜索一下有关投资这方面的，但最先映入眼帘的问题却是“学英语的收益”。其实，不知为何，我几天前就在知乎搜索过英语了。而在今天呢，看一下咪蒙的文章，没想到也是在为英语打广告，所以，这个世界真的神奇。

I searched the keyword 'profit' in zhihu last night, as you know ,i searched which about investment, but the first line in result is a question——what's the profit of learning english ? To be honest ,i had searched the keyword 'english' a few days ago somehow. Today, i read the article of Mimeng, Unexpectly, the article is a advertisement of english! so, how wonderful this world is.
