语言素材：
"Who questions much, shall learn much, and remember much."-Francis Bacon (1561 -1626)
It seems obvious now how we acquire knowledge and understanding. To start with, you need questions. Then, to find answers, you observe the world around you and study the facts. After that you consider possible answers and test each to find the right ones. Although today we are more accustomed to typing a few key words into a search engine and waiting for the Internet to spit the answer out for us, modern scientists and thinkers are still solving the world's problems with this type ofanalysis-luckily for us.
However, in the17th century when Francis Bacon suggested that this type of thinking was the way to gain knowledge, he was going against the views of the day. Bacon held an important rank under King James (1566-1625) of England but his true interest was not the day to day bureaucratic details of the government, but the worthy search for knowledge.
