发明的才能

They also toppled the theory that humans could not leave Africa until they had invented Acheulean technology.

同时，这也颠覆了人类直到发明阿歇尔技术之后才能离开非洲的理论。

I had never handled a tool in my life, and yet in time by labour, application, and contrivance, I found at last that I wanted nothing but i could have made it, especially if 1 had had tools; however i made abundance of things, even without tools, and some with no more tools than an adze and a hatchet, which perhaps were never made that way before, and that with infinite labour.

我一生从未使用过任何工具，但久而久之，以我的劳动、勤勉和发明设计的才能，我终于发现，只要有适当的工具，我什么东西都能做。尽管我没有什么工具，却也制造了许多东两，有些东西制造时，仅用了一把手斧和一把斧头。我想没有人会用我的方法制造东西，也没有人会像我这样付出无穷的劳动。

I had never handled a Tool in my Life, and yet in time by Labour, Application, and Contrivance, I found at last that I wanted nothing but I could have made it, especially if I had had Tools; however I made abundance of things, even without Tools, and some with no more Tools than an Adze and a Hatchet, which perhaps were never made that way before, and that with infinite Labour: For Example, If I wanted a Board, I had no other Way but to cut down a Tree, set it on an Edge before me, and hew it flat on either Side with my Axe, till I had brought it to be thin as a Plank, and then dubb it smooth with my Adze.

我一生从未使用过任何工具，但久而久之，以我的劳动、勤勉和发明设计的才能，我终于发现，我什么东西都能做，只要有适当的工具。然而，尽管我没有工具，也制造了许多东西，有些东西我制造时，仅用一把手斧和一把斧头。

His skillful contrivance of answers to every problem.

不要把你的发明才能浪费在找借口上。

His contrivance in the main represented the principle of the kite.

他的发明才能主要体现在那只"大鸟"的原理上。

Sometime I contriv'd to dig a Hole under the Place where they made their Fire, and put in five or six Pound of Gun-powder, which when they kindled their Fire, would consequently take Fire, and blow up all that was near it; but as in the first Place I should be very loth to wast so much Powder upon them, my Store being now within the Quantity of one Barrel; so neither could I be sure of its going off' at any certain Time, when it might surprise them, and at best, that it would do little more than just blow the Fire about their Ears and fright them, but not sufficient to make them forsake the Place; so I laid it aside, and then propos'd, that I would place my self in Ambush, in some convenient Place, with my three Guns, all double loaded; and in the middle of their bloody Ceremony, let fly at them, when I should be sure to kill or wound perhaps two or three at every shoot; and then falling in upon them with my three Pistols, and my Sword, I made no doubt, but that if there was twenty I should kill them all: This Fancy pleas'd my Thoughts for some Weeks, and I was so full of it, that I often dream'd of it; and sometimes that I was just going to let fly at them in my Sleep.

就我目前的境况而言，我其实不缺多少东西。可是，我总感到，由于受到那些野蛮的食人生番的惊吓，因而时时为自己的安全而担惊受怕。以往，为使自己的生活过得舒服，我充分发挥了创造发明的才能，但现在就无法充分发挥了。我本来有一个煞费苦心的计划，想试验一下能否把大麦制成麦芽，再用麦芽来酿起酒。现在，这一计划也放弃了。当然，这实在也是一个荒唐的念头，连我自己也经常责备自己把事情想得太简单了。因为我不久就看出，许多酿造啤酒必不可少的材料我都没有，也无法自己制造。首先，没有啤酒桶。前面说过，我曾尝试做木桶，但怎么也做不好。我曾花了许多天、甚至许多星期、许多个月，结果还是没有成功。其次，没有啤酒花使酒经久不坏，没有酵母发酵，没有铜锅铜罐煮沸。可是，尽管如此，我还是坚信，要是没有对食人生番的惊惧和恐怖，我早就可能着手去做了，甚至也许已做成功了。

Before the invention of the postage stamp, letters were 'franked'. This meant that it was marked on the letter that delivery had been paid for. This could have been either written or stamped. A post-mark was also stamped on the letter. Invented in 1660 in England, this was a mark that showed where and when the letter had been posted. It was used to see how long it took to deliver the letter-to make sure the service was reliable.

在邮票发明之前，信件被用来做印记的，这就意味邮件付费了才能在你的信上标记号，可以用手写，也可以做印记，那么邮政记号也会被印到这个信上，在1660年英国发明邮票之前，那么有一个记号会显示哪里什么时候这个信寄出，那么主要用来发送这个信多长时间来确保这个服务可靠性。

As in my present Condition there were not really many Things which I wanted; so indeed I thought that the Frights I had been in about these Savage Wretches, and the Concern I had been in for my own Preservation, had taken off the Edge of my Invention for my own Conveniences; and I had dropp'd a good Design, which I had once bent my Thoughts too much upon; and that was, to try if I could not make some of my Barley into Malt, and then try to brew my self some Beer: This was really a whimsical Thought, and I reprov'd my self often for the Simplicity of it; for I presently saw there would be the want of several Things necessary to the making my Beer, that it would be impossible for me to supply; as First, Casks to preserve it in, which was a Thing, that as I have observ'd already, I cou'd never compass; no, though I spent not many Days, but Weeks, nay, Months in attempting it, but to no purpose.

The answer is 40.the scientists were jerry mariment、jim fanteso and jack kilty their first device could add、subtract、multiply and divide.it had 12byte of memory close to nothing compared to today's heavy powerful calculators and it weighed more than 1 kilogram.but it was powerd by batteries that meant it could be taken anywhere.other electronic calculators had to be plugged into electricity.not only that they weighed close to 24kilograms

答案是40年前。3位科学家分别是JERRY、JAMES和JACK，他们发明的第一台计算器可以加、减、乘、除。并且有12字节的内存，这当然与今天的强大的计算器所无法比较的，它重1公斤。但是它是靠电池驱动的，这意味着可以被带到任何地方。其他的电子计算器带插头，必须接电源才能使用，而且重达24公斤几乎和打字机一样大。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.
