难以取悦地

But never was a Fight manag'd so hardily, and in such a surprizing Manner, as that which follow'd between Friday and the Bear, which gave us all (though at first we were surpriz'd and afraid for him) the greatest Diversion imaginable: As the Bear is a heavy, clumsey Creature, and does not gallop as the Wolf does, who is swift, and light; so he has two particular Qualities, which generally are the Rule of his Actions; First, As to Men, who are not his proper Prey; I say, not his proper Prey; because tho' I cannot say what excessive Hunger might do, which was now their Case, the Ground being all cover'd with Snow; but as to Men, he does not usually attempt them, unless they first attack him: On the contrary, if you meet him in the Woods, if you don't meddle with him, he won't meddle with you; but then you must take Care to be very Civil to him, and give him the Road; for he is a very nice Gentleman, he won't go a Step out of his Way for a Prince; nay, if you are really afraid, your best way is to look another Way, and keep going on; for sometimes if you stop, and stand still, and look steadily at him, he takes it for an Affront; but if you throw or toss any Thing at him, and it hits him, though it were but a bit of a Stick, as big as your Finger, he takes it for an Affront, and sets all his other Business aside to pursue his Revenge; for he will have Satisfaction in Point of Honour; that is his first Quality: The next is, That if he be once affronted, he will never leave you, Night or Day, till he has his Revenge; but follows at a good round rate, till he overtakes you.

紧接着，星期五和那只大熊之间展开了一场最大胆、最惊人的大战。这场大战起初确实使我们胆战心惊，最后却使大家开怀大笑。熊的身体笨重，行动蹒跚，跑起来当然没有狼那样轻快。因此，他的行动有两个特点。第一，对人来说，他一般不把人当作猎食的对象；当然，像现在这样大雪遍地，极端饥饿的时候，这笨拙的大家伙是否也会吃人，那就很难说了。一般来说，要是在树林里遇到熊，你不去惹它，它也不会来惹你。不过，你得特别小心，要对它客气，给它让路，因为它是一位特别难以取悦的绅士，即使是一位王子走来，它也不肯让路。如果你真的害怕，最好不要看它，继续走你的路。如果你停下来，站着正视它，熊就认为是对它的侮辱。如果你向它丢点什么东西，打中了它，哪怕是一根小小的树枝，只有你手指头那么粗，熊也认为是一种侮辱。这时，它会把一切丢开不管，一心只想报仇，不达目的决不罢休。这有关它的荣誉问题，它一定要把面子挣回来才算满足。这是熊的第一个特点。第二个特点是，熊一旦受到侮辱，就会不分昼夜地跟着你，一直到报了仇才罢休，哪怕绕上许多路，也要赶上你，抓住你。
