【小编摘要】这个原始人真是事后诸葛亮！
I invented fire, but now everyone is using it for free. In hindsight, maybe my first invention should have been intellectual property law.
我发明了火，但是现在每个人都在免费使用火。事后想一想，也许我首先应该发明知识产权法。
知识点津：
1. invent 发明
invent an excuse 找借口
2. for free 免费
Some channels will be given away for free, while others are for paying subscribers only.
一些频道将会免费开放，而另外一些则只有付费用户可以观看。
3. hindsight n. 后见之明 in hindsight 事后回想
4. intellectual property right 知识产权，常常简写为IPR。
