1. What position did Bacon hold during his days and what was his true interest
2. At first people approved of Galilei’s studies, but later they got angry. Why
Bacon held an important rank under King James (1566–1625) of England. His true interest was the worthy search for knowledge.
They didn’t want to challenge what they had always thought was true.
Careful reading

No. Galilei made mistakes. He believed that the Earth moved round the sun in a perfect circle. But he was wrong.

Because they were unwilling to challenge what they had always comfortably believed.
Careful reading

Understanding Coherence in Context
The repetition of key terms or phrases makes meaning coherent in a text.
The use of synonyms and antonyms helps enhance coherence in a text.
Linking words such as since, so, afterwards, then, although, but, however, etc. can help connect meanings in sentences.
Pronouns such as he, she, it, they, etc. help carry meaning on into the next point in a text.

Language and grammar
Focus on Language: Difficult sentence
It seems obvious now how we acquire knowledge and understanding.
今天，如何获取知识、认识世界，人人皆知。
解析：It是形式主语，后面how引导的从句是真正的主语。
It is + adj +其余成分。
obvious = clear 明显的

Focus on Language: Difficult sentence
At that time, people believed more in the church than in facts, and people like Galileo Galilei (1564-1642), who proved the idea that “the Earth is not the centre of the universe” were often punished by the church with no one coming to their defence. 那时人们相信教会胜过相信事实，像伽利略那样证明了“地球不是宇宙中心”的人物，往往会被教会惩罚，也没有人会为他们辩护。
解析：who引导非限制性定语从句，修饰先行词Galileo Galilei；that引导同位语从句，解释名词idea的内容。其次，with是复合结构，在句中作状语。no one与come之间是逻辑上的主谓关系。
