弗朗西斯·培根（1561-1626）,英国哲学家，英国唯物主义和现代实验科学的始祖。历任律师、下院议员、掌玺大臣、大法官。提出“知识就是力量”。对归纳法做了系统的论述，被认为是归纳逻辑的创始人。
伽利略·伽利莱（1564-1642），意大利物理学家、天文学家，近代实验科学的奠基者之一。伽利略从实验中总结出自由落体定律，推翻了亚里士多德的很多学说。还发现了惯性定律和抛体运动规律等，确定了力学相对性原理，因此被认为是经典力学和实验物理学的先驱。他是利用望远镜观察天体取得大量成果的第一人。

Understanding Cherence in CntextThe repetitin f key terms r phrases makes meaning cherent in a text. The use f synnyms and antnyms helps enhance cherence in a text.Linking wrds such as since, s, afterwards, then, althugh, but, hwever, etc. can help cnnect meanings in sentences.Prnuns such as he, she, it, they, etc. help carry meaning n int the next pint in a text.
Circle the linking wrds in the text that the writer used in rder t express his / her pinin cherently.
It seems bvius nw hw we acquire knwledge and understanding. T start with, we need questins. Then, t find answers, we bserve the wrld arund us and study the facts. After that, we cnsider pssible answers and test each t find the right nes. Althugh tday we are mre used t typing a few key wrds int a search engine and waiting fr the Internet t give us an answer, mdern scientists and thinkers are still slving the wrld’s prblems with this type f analysis—luckily fr us.Hwever, in the 17th century when Francis Bacn (1561-1626) suggested that this type f thinking was the way t gain knwledge, he was ging against the views f the day. Althugh Bacn held an imprtant rank in King James’ ryal curt f England, his true interest was nt the day-t-day, slw and inefficient wrking style f the gvernment, but the wrthy search fr knwledge. This was certainly nt the interest f mst peple in his days. At that time, peple believed mre in the church than in facts, and peple like Galile Galilei (1564-1642), wh prved the idea that “the Earth is nt the centre f the universe”, were ften punished by the church with n ne cming t their defence.
Therefre, ur understanding f the wrld arund us is cnstantly grwing and changing. In ther wrds, we learn mre every day and nne f us can ever sit back and say, “We knw it all.” We need t thank the great men f the past fr their wisdm. They understd that we dn’t knw everything and prbably never will, as this wuld mean a wrld with questins.We we s much f ur knwledge and understanding f the wrld t peple like Bacn and Galilei, wh were brave enugh t step ut frm the shadws f cnventinal thught in rder t find the kingdm f knwledge that tday’s civilisatin is built upn. These men knew that knwledge and understanding are things t fight fr; mre vital t a man, and mre beneficial t mankind, sme might say, than all the mney in the wrld.
Think and share1. What d yu think the last sentence f the passage means?I think the last sentence f the text means that knwledge and understanding are mre imprtant than mney. They are mre helpful and useful because they can guide ur ways f learning abut the wrld and help us slve prblems all the time while mney can just buy certain gds and slve prblems fr sme time.

2. What is the writer’s attitude twards the way t acquire knwledge? Hw did the writer make his / her pinin clear t the readers? Underline the expressins that shw the writer’s attitude.The writer’s attitude t acquiring knwledge is t keep asking questins and respect facts. We d nt just accept answers frm authrity.The writer illustrated his / her pints by using examples f Galilei and ideas frm great thinker like Bacn.The expressins that shw the writer’s attitudes are like: it seems bvius, luckily fr us, hwever, it is nt surprising, primitive ideas, it felt like, make the assumptin, was wrng at times, sit back and say, a wrld with questins, we s much ... t, step ut frm the shadw, t find the kingdm f knwledge, mre vital t, mre beneficial t ...
