Nature 上一个博士生写的小散文，挺不错的：

There’s a book handed down in my lab from previous graduate students called “How to get a PhD”. It can be boiled down to five steps: 1. Become a postgraduate. 2. Choose project question. 3. Get data. 4. Write thesis. 5. Pass thesis defence. But a PhD is more than getting your mates to call you ‘doctor’. (Although that does have a ring about it…) PhD students need to make themselves known to the scientific community, they need to learn many different skills that make them employable as a postdoc, and most of all, they need to publish.
