Step Ⅲ Careful reading

Read the text again and try to answer the following questions:

Para.1:

Q1:What do you know about the great thinkers from Paragraph 1?

(Thinkers who have changed the world do not seem to have much in common.They come from different cultures and have different backgrounds,and only some of them did well at school.)

Q2:How do you think of creativity/creative thinking?

(Creativity is not about getting hight test scores,having a hight IQ or being smart.Instead,it seems that creative thinking,which is one of the most highly valued skills in society,is a matter of habits.)

Q3:How can we become more creative?

(By thinking about the way we think and practising good thinking strategies,we can become more creative.)

Para.2:

Q4:What're the relations among the knowledge,learning and thinking?

(Knowledge and learning are important if we want to be successful,but we must also realise that what we know and what we have learnt may also limit our thinking.)

Q5:Why do inventors often rephrase a problem and try "impossible " or "crazy" solutions?

(If we look only for the correct answer and reject ideas that do not provide a complete answer,we may get stuck.Partial solutios,and even failures,give us more information and clues that help us move towards a better solution.)

Q6:What's "creative thinking"?

(Creative thinking is a conscious effort to break away from old thought patterns in order explore new possibilities.)

Para.3:

Q7:Where do good solutions and new ideas come from?

Q8:What can creative thinkers find by looking at a problem in as many ways as possible?

(creative thinkers can find solutions that would otherwise remain invisible.)

Q9:What can improve our understanding and make it easier to discover new possibilities?

(Each new way of looking at a situation improves our understanding and makes it easier to discover new possibilities.)

Para.4

Q10:How and why should we connect the new and the old ideas ?

(We should try to combine new and old ideas in as many different ways as possible.

because every new thought or idea has to be connected to what we already know.Unfortunately,it is easy to limit the possibilities of a new idea by connecting it to only area of our previous knowledge.)

Para.5

Q11:Are good ideas accident?Why?

(Good ideas are no accident.They are the result of a long process of trial and error.)
