It happen'd, being in Company with some Merchants and Planters of my Acquaintance, and talking of those things very earnestly, three of them came to me the next Morning, and told me they had been musing very much urn what I had discoursed with them of, the last Night, and they came to make a secret Proposal to me; and after enjoining me Secrecy, they told me, that they had a mind to fit out a Ship to go to Guinea, that they had all Plantations as well as I, and were straiten'd for nothing so much as Servants; that as it was a Trade that could not be carried on, because they could not publickly sell the Negroes when they came home, so they desired to make but one Voyage, to bring the Negroes on Shoar privately, and divide them among their own Plantations; and in a Word, the Question was, whether I would go their Super-Cargo in the Ship to manage the Trading Part upon the Coast of Guinea?

有一次，我与一些熟悉的种植园主和商人又很起劲地谈论这些事情。第二天上午，有三个人来找我。他们对我说，他们对我昨天晚上的谈话认真思考了一番，特前来向我提出一个建议。但他们说，这建议必须保密。因此他们要求我严守秘密。然后，他们对我说，他们想装备一条船去几内亚。他们说，他们都像我一样有种植园，但最感缺乏的是劳动力。他们不可能专门从事贩运黑奴的买卖，因为他们回巴西后不可能公开出售黑奴，因此，他们打算只去几内亚一次，回巴西后把黑奴偷偷送上岸，然后大家均分到各自的种植园里去。简而言之，现在的问题是，我愿不愿意管理他们船上的货物，并经办几内亚海岸交易的事务。

Here, I'm firing up a subshell to execute the ping -i 1 -c 1 command, which on my system requests ping have a 1-second timeout, and selects (as Sean Connery's character said in The Hunt for Red October so eloquently) ''one ping only''.

这里，我们创建了一个子进程来执行 ping -i 1 -c 1 命令，这个命令只会 ping 目标主机一次，而且设置了超时时间为1秒。并选择（像肖恩-康纳利在《追击红色十月》里演的那个角色一样非常意味深长地说）"只 ping 一次"。

Or we could tell of that cake the pirates cooked so that the boys might eat it and perish; and how they placed it in one cunning spot after another; but always Wendy snatched it from the hands of her children, so that in time it lost its succulence, and became as hard as a stone, and was used as a missile, and Hook fell over it in the dark.

或者我们还可以讲讲，海盗们做的那只孩子们吃了就会死去的大蛋糕，海盗们怎样一次又一次把它放在巧妙的地方。可是，温迪每次都从孩子们手中把它夺走；渐渐地，那蛋糕的水分干了，硬得像块石头，可以当作一个飞弹来用。夜里，胡克不小心蹴上了它，摔了一跤。
