He said two objects of different weight would land together. ———伽利略·伽利莱 All truths are easy to understand once they are discovered; the point is to discover them. 所有的真理一旦被发现就很容易理解；关键是要发现它们. 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。 Who questions much, shall learn much, and remember much. ———弗兰西斯·培根 多问，多学，多得。 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、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。 Plato is dear to me, but dearer still is truth。 . --亚里士多德 --吾爱吾师，吾更爱真理 What’s the main idea of the text A.

Fast reading: Careful Reading: How do people acquire knowledge and achieve understanding now (para 1) questions observe the world around us and study the facts consider possible answers and test each to find the right ones It seems obvious now how we acquire knowledge and understanding. To start with, we need questions. Then, to find answers, we observe the world around us and study the facts. After that, we consider possible answers and test each to find the right ones. Although today we are more used to typing a few key words into a search engine and waiting for the Internet to give us an answer, modern scientists and thinkers are still solving the world’s problems with this type of analysis—luckily for us. 第三课 认识世界 今天，如何获取知识、认识世界，人人皆知。首先，我们需要问题。然后，为了寻找答案，我们观察周围的世界并研究相关事实。之后，我们思考可能的答案并逐个验证，以找到正确答案。尽管我们现在更习惯于在搜索引擎中敲几个关键词，等待互联网为我们提供答案，但当代科学家、思想家仍采用这种分析方式来解决问题———我们应该为此感到庆幸。 How did people acquire knowledge and achieve understanding in the past (para 2-3) Francis Bacon Galileo Galilei Aristotle People in the 17th century Careful Reading: Read paragraphs 2-3.
