I don't know what forges a good leader,but i do know what constitutes a bad one:one who puts his employees in the frontline rather than himself;one who relegates responsibilities;one who tries to please everyone;one who only works from nine to five;one who neither punishes nor rewards.

我不知道什麼是所谓的「成功的领导」，但我知道什麼是「不成功的领导」。就是：不身先士卒的领导；遇事推诿的领导；希望讨好每个人的领导；招九晚五的领导；赏罚不分的领导。

When I meet the engine with its train of cars moving off with planetary motion —— or, rather, like a comet, for the beholder knows not if with that velocity and with that direction it will ever revisit this system, since its orbit does not look like a returning curve —— with its steam cloud like a banner streaming behind in golden and silver wreaths, like many a downy cloud which I have seen, high in the heavens, unfolding its masses to the light —— as if this traveling demigod, this cloud-compeller, would ere long take the sunset sky for the livery of his train; when I hear the iron horse make the hills echo with his snort like thunder, shaking the earth with his feet, and breathing fire and smoke from his nostrils（what kind of winged horse or fiery dragon they will put into the new Mythology I don't know）, it seems as if the earth had got a race now worthy to inhabit it.

当我遇见那火车头，带了它的一列车厢，像行星运转似的移动前进，——或者说，像一颗扫帚星，因为既然那轨道不像一个会转回来的曲线，看到它的人也就不知道在这样的速度下，向这个方向驰去的火车，会不会再回到这轨道上来，——水蒸汽像一面旗帜，形成金银色的烟圈飘浮在后面，好像我看到过的高高在天空中的一团团绒毛般的白云，一大块一大块地展开，并放下豪光来，——好像这位旅行着的怪神，吐出了云霞，快要把夕阳映照着的天空作它的列车的号衣；那时我听到铁马吼声如雷，使山谷都响起回声，它的脚步踩得土地震动，它的鼻孔喷着火和黑烟（我不知道在新的神话中，人们会收进怎样的飞马或火龙），看来好像大地终于有了一个配得上住在地球上的新的种族了。

A person who stays away from power, profit and luxury is clean. However, a man who stays near them but is free from their influence is even cleaner. He who is ignorant of tactics and tricks is noble. Nevertheless,a person who knows them well but distains to use them is even nobler.

面对世上纷纷扰扰地追逐名利的恶行，不去接近是志向高洁，然而接近了却不受污染则更为质量高尚；面对计谋权术这样的奸滑手段，不知道它的人固然是高尚的，而知道了却不去用这种手段者则无疑更为高尚可贵。

I'm sure I'm not Ada,' she said, 'for her hair goes in such long ringlets, and mine doesn't go in ringlets at all; and I'm sure I can't be Mabel, for I know all sorts of things, and she, oh!

&我敢说，我不是爱达，&爱丽丝说，因为她是长长的卷发，而我的根本不卷。我肯定不是玛贝尔，因为我知道各种各祥的事情，而她，哼！她什么也不知道。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
