Task 3
P54 A
Write a summary of the lecture transcript.
Use the following ideas to help you.
His personal experience
His ideas on the value of science
When Richard Feynman was young, he thought the only use for science was to make good things for people. However, after he worked on the atomic bomb, he realized that science could also be used for evil. He wondered what the value of science really was and he decided on three values. The first value is that scientific knowledge enables us to do and make all kinds of things. The second is the intellectual enjoyment it can provide us with. And the third value is scientists' freedom to doubt.
analysing, mindmap, summary, retelling
It is our responsibility as scientists, knowing the great
progress that is the fruit of freedom of thought, to
declare the value of this freedom; to teach how doubt
is not to be feared but to be welcomed and discussed;
and to demand this freedom as our duty to all coming
generations.
形式主语
真正的主语:三个并列的动词不定式短语
V-ing形式作原因状语
vt. 声明,宣称
① He declared that he would never go back on his
words.
② She declared herself extremely hurt by his lack of
support.
他宣称他绝不食言。
她说自己非常伤心,因为他没有得到支持。
作为科学家,我们明白巨大进步源于思想自由,因此,我们有责任声明这一自由的价值;有责任教育人们不必害怕怀疑,而要欢迎怀疑、讨论怀疑;有责任强烈要求这一自由,这就是我们对后世的义务。
Sentence analysing for better understanding.
Feynman believes that of all science's many values, the greatest must be the freedom to doubt. How do you understand this
P54 B
Possible answer:
This belief expresses a similar meaning to this unit's opening quote “The scientist is motivated primarily by curiosity and a desire for truth. “Only when scientists raise doubts can they open up the opportunity to explore the unknown, which is what leads to scientific achievements. Feynman further emphasizes this value when he says, “Permit us to question-to doubt-to not be sure.” He points out that scientists must always be allowed to question and doubt things, because he knows it is the key to how science is able to progress.
