To milk my She-goats, and manage my little Flock, in the Wood; which as it was quite on the other Part of the Island, was quite out of Danger; for certain it is, that these Savage People who sometimes haunted this Island, never came with any Thoughts of finding any Thing here; and consequently never wandred off from the Coast; and I doubt not, but they might have been several Times on Shore, after my Apprehensions of them had made me cautious as well as before; and indeed, I look'd back with some Horror upon the Thoughts of what my Condition would have been, if I had chop'd upon them, and been discover'd before that, when naked and unarm'd, except with one Gun, and that loaden often only with small Shot, I walk'd every where peeping, and peeping about the Island, to see what I could get; what a Surprise should I have been in, if when I discover'd the Print of a Man's Foot, I had instead of that, seen fifteen or twenty Savages, and found them pursuing me, and by the Swiftness of their Running, no Possibility of my escaping them.

羊群在岛的另一边，因此没有什么危险。因为那些偶尔上岛的野人，从来没有想在岛上找到什么东西，所以他们从不离开海岸向岛里走。我也毫不怀疑，自从我处处小心提防他们之后，他们还照常到岛上来过好几次。真的，我一想到我过去出游的情况，不禁不寒而栗。我以前外出只带一支枪，枪里装的也是一些小子弹。就这样我在岛上到处东走走，西瞧瞧，看看能不能弄到什么吃的东西。在这种情况下，假使碰上他们，或被他们发现，我该怎么办呢？因为，我没有多少自卫能力。或者，假定我当时看到的不是一个人的脚印，而是一二十个野人，一见到我就向我追来。他们善于奔跑，我是无论如何跑不过他们的，那我必定会落在他们手里！

I've played the thief But it's been 14 Years of silence It's been 14 Years of pain It's been 14 Years that are gone forever Your stupid girlfriends tell you That I'm to blame Well they're all used-up has-beens Out of the game This time I'll have the last word You hear what I say I tried to see it your way It won't work today You just don't step inside to 14 Years So hard to keep my own head...that's what I say You know...I've been the dealer...

他们都试图打败但它已 14年的沉默这是 14岁的疼痛这是 14岁的一去不复返和我永远也不会再次您的愚蠢女友告诉你，我责怪那么他们都用行动已- beens 出局这一次我要硬道理你听到我说什么我想看到你的方式它不会今天的工作你刚才不一步内到14岁因此，努力保持我自己的头部。。。这就是我要说你知道。。。我一直在该交易商。。。

II. Yet nevertheless of late divers commissions directed to sundry commissioners in several counties, with instructions, have issued; by means whereof your people have been in divers places assembled, and required to lend certain sums of money unto your Majesty, and many of them, upon their refusal so to do, have had an oath administered unto them not warrantable by the laws or statutes of this realm, and have been constrained to become bound and make appearance and give utterance before your Privy Council and in other places, and others of them have been therefore imprisoned, confined, and sundry other ways molested and disquieted; and divers other charges have been laid and levied upon your people in several countie:（y lord lieutenants, deputy lieutenants, commissioners for musters, justices of peace and others, by command or direction from your Majesty, or your Privy Council, against the laws and free custom of the realm.

The Net Charges of main atoms, bond lengths, bond angles, dihedral angles, IR have been calculated by means of HyperChem6. 0 program. 36 kinds of Schiff base derivatives of benzylidene adenine have been designed. Also the net charges of main atoms, bond lengths, bond angles, dihedral angles, IR, the energy gap △E between HOMO and LUMO and the nonlinear second-order polarizability β have been calculated by means of HyperChem6. 0 program.
