英语单词superadd怎么读

A. 英语高手帮忙翻译一下吧，给高分+追加分

The average age of China in 1949 was just over 30 years old, but in 2009 it was more than 70 years. Although there were many wars before, but there is also a factor which plays a vital role, that is medical technology.

From the historical process of human development, with the development of medical technology, we can better understand the human body and its possible health conditions, such as the invention of the microscope ,which contributed a comprehensive understanding of microscopic substances ,such as human cells; th discovery and application of penicillin saved countless lives; th applicationof medical equipment allows physicians to diagnose the patient's disease; th invention of vaccine enables humans to better prevent disease. Progress in medical technology has indeed made the threat to human health, such as diseases, timely prevented,diagnosed and treated, and the quality of human life improved as well as human life cycle extended.

Let's do a bold vision, along with the development of better medical technology, perhaps a few more years later, it will not be merely a dream for human to live to two hundred years or even five hundred years . Human cloning technology can be used to clone the organs needed to invent a universal medicine to cure cancer and other fatal diseases; we can also use gene technology to diagnose and treat currently intractable diseases. Perhaps mankind can really live forever, unless, 2012 end of the world really happened.

In fact, the current medical standards are far advanced to imagine, there are many incurable diseases threatening our lives. Therefore, we still have a lot of things to do, there is still a long way to go.

B. 求阿克顿(Lord Acton) 英语原文:权力导致腐败,绝对权力导致绝对的腐败

阿克顿原话出自下面这段信(Dalberg-Acton, John Emerich Edward (1949), Essays on Freedom and Power, Boston: Beacon Press, p. 364)：
"I cannot accept your canon that we are to judge Pope and King unlike other men with a favourable presumption that they did no wrong. If there is any presumption, it is the other way, against the holders of power, increasing as the power increases. Historic responsibility has to make up for the want of legal responsibility. All power tends to corrupt and absolute power corrupts absolutely. Great men are almost always bad men, even when they exercise influence and not authority: still more when you superadd the tendency or certainty of corruption by full authority. There is no worse heresy than that the office sanctifies the holder of it."
但是通常引用的时候都是用的简化的更上口的形式：
Power corrupts; absolute power corrupts absolutely.

C. 英语单词 有一个单词，中文意思是证实还是证明，但是是以super打头的，怎么想也想不起来了。

superable 可以胜过的,可征服的
superadd 再加上,添加
substantiate 用事实支持(某主张、说法等);证明,证实
super开头的貌似没有证实 证明 找到一个s开头的证明证实 不知道是不是这个
