留神

Unfortunately for, the experimental philosophy of the female to whose protecting care Oliver Twist was delivered over, a similar result usually attended the operation of _her_ system; for at the very moment when the child had contrived to exist upon the smallest possible portion of the weakest possible food, it did perversely happen in eight and a half cases out of ten, either that it sickened from want and cold, or fell into the fire from neglect, or got half-smothered by accident; in any one of which cases, the miserable little being was usually summoned into another world, and there gathered to the fathers it had never known in this.

接受委托照看奥立弗·退斯特的那位女士也信奉实验哲学，不幸的是，她的一套制度实施起来也往往产生极其相似的结果。每当孩子们已经训练得可以依靠低劣得不能再低劣的食物中少得不能再少的一部分活下去的时候，十个之中倒有八个半会出现这样的情形：要么在饥寒交迫下病倒在床，要么一不留神掉进了火里，要不就是偶然之间给呛得半死，只要出现其中任何一种情况，可怜的小生命一般都会被召到另一个世界，与他们在这个世界上从未见过的先人团聚去了。

My father was always saying the inn would be ruined, for people would soon cease coming there to be tyrannised over and put down, and sent shivering to their beds; but I really believe his presence did us good.

Pickle from their cool green Mason jars, he began to loosen his tie and unbutton his vest, always looking around as if he should be careful and ready to button up again.

他给妻儿分夹心面包，又从冰凉的绿色大口坛里掘出泡菜，一边开始松开领带，解开背心的扣子，但他不时还四处张望，好像必须留神，随时准备把它扣上似的。

Be mindful of any sore or stiff spots spending a bit more time over those areas.

留神看哪里痛和僵硬，就多花几分钟按摩这些地方。

Yeah, I could clearly make sure that she was telling the truth. Then, we could also hear the noise from outside, from the stair well exactly.

很不幸的是，一不留神，居然吃掉了半颗牙，天哪，到时候重新做颗烤瓷牙，总共又得一千多，什么世道，越是没钱犯穷的时候，越是不得已要花一大笔。

They spoke in hushed tones and glanced cautiously about them fearful of being heard or observed.

But when we take the time to explore the paradoxes and vagaries of English, we find that hot dogs can be cold, darkrooms can be lit, homework can be done in school, hours – especially happy hours and rush hours – can last longer than sixty minutes, quicksand works very slowly, boxing rings are square, silverware can be made of plastic and tablecloths of paper, and most telephones are dialed by being punched.

然而，一旦留神去想想那些自相矛盾、稀奇古怪的用法，我们会发现热狗其实是凉的，暗房其实是有灯的，家庭作业原来是在学校完成的，小时——特别是&欢乐时分&&高峰时分&—其实远比60分钟长，流沙其实是慢的，拳击场其实是方的，餐具其实可以是塑料的，桌布其实是纸做的，而且，电话不是拨的而是按的。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
