1. Robertson was a doer, not a thinker. 罗伯逊是个实干家，不是个思考者。
2. Now though the doer of it be a duke's son he shall rue it! 哼，即使做这件事的人是公爵的儿子，他也要后悔的！
3. As I have been writing and talking about space flight for the best part of 20 years, a sudden switch of interest to the depth of the sea doer seem peculiar. 在20年的绝大部分时间里，我一直在撰写和谈论太空飞行，突然对深海探险者的兴趣发生了转变，这似乎有些奇怪。
4. Even if there is no concrete benefit paid in response to your good deed, at the very least, the doer of the good deed has the opportunity to enjoy a kind of spiritually enlightened moment. 即使你的善行没有带来任何具体的回报，至少行善的人有机会享受一种精神上的启迪。
5. I think what Aesop was suggesting is that when you offer a good turn to another human being, one can hope that that good deed will come back and sort of pay a profit to you, the doer of the good deed. 我认为伊索的意思是，如果你对别人行善，你可以希望这一善事会反过来使你，也就是做这件善事的人，在某种程度上受益。
