英语必修5人教版新课标Unit 1第5教案
Period 5 Reading and writing (Using Language)
Teaching Goals: 1. To develop Ss’ reading ability.
2. To develop Ss’ writing ability.
3. To get Ss to learn something about Nicolaus Copernicus.
Teaching Procedures: Step 1. Warming Up
Purpose: To lead Ss to the topic and arouse their interest in Copernicus. Ask Ss to discuss the questions below:
1. Who is the man in the left picture? 2. What about the right picture?
3. Do you know the relationship between them? Ask Ss to present their views. Step 2 Reading
Purpose: To find some details in the text.
1. Ask Ss to discuss the following questions in pairs and answer them. Q1. What made Copernicus confused?
Q2. Why couldn’t he tell about his theory? Q3. What’s Christian’s view of universe? Q4. When did he first show his theory? To whom? Q5. What’s his friends’ reaction to the theory? Q6. When was the theory published? Why? Q7. What’s the evaluation of the theory?
Suggested answers:
A1. His mathematical calculations led to the same conclusion: that the earth was not the center of solar system.
A2. He could not tell anyone about his theory as the powerful Christian Church would have punished him for even suggesting such an idea.
A3. They believed God had made the world and for that reason the earth was special and must be the center of the solar system. A4. In 1515 he showed it privately to his friends.
A5. His friends were enthusiastic and encouraged him to publish his ideas. A6. He did not want to be attacked by the Christian Church, so he only published it as he lay dying in 1543.
A7. Now people can see that there is a direct link between his ideas and the work of Isaac Newton, Albert Einstein and Stephen Hawking. 2. Group work
Divide Ss into three groups and discuss the following question. Ask every group to present their ideas.
If you were Nicolaus Copernicus, would you have hidden your theory for so many years? Why?
Step 3. Writing
Purpose: To learn to write a persuasive essay.
Write a short letter asking Copernicus to publish his ideas so that everyone can read them.
First you need to collect your ideas. For example: ? He believes his new theory is true. ? There are problems with the present theory.
? He has done many years of observations to prove his new theory is true. ? Science can not develop unless people publish their ideas. ? Time will show if his theory is true of now. Here is a plan:
Beginning: Tell Copernicus who you are and why you want him to publish his ideas.
Paragraph 1: Reason 1 and evidence. Paragraph 2: Reason 2 and evidence.
Summing up: Ask him to think again about publishing his ideas.
One Possible version: Dear Nicolaus Copernicus,
I am a student studying astronomy and I would very much like to read your new theory about the solar system. I hope you will publish it for several reasons. I understand the problems with the present theory. The way the planets move is not what you would expect if the earth was the center of the universe. It is also odd that the brightness of some stars seems to change. So I agree with you that we need a new theory.
I know your observations have been very carefully carried out over many years. Now you must have the courage to publish them. Science can never advance unless people have the courage of their beliefs. I know you worry about what will happen if you publish your new theory. No matter how people oppose it, time will show if your ideas are right or wrong.
So I hope you will feel you can publish your new theory.
Yours sincerely,
***
Step 4. Extension
Purpose: To deepen what we have learned in the Writing part.
Let us pare a persuasive essay with a report, a description and a creative piece and then find similarities and differences between these kinds of writing.
Report Description Creative writing/story Formal language with few Vivid use of words with Vivid use of language adjective No speech similes and metaphors and more informal style. except No speech except to help Speech to show feelings, the description reactions etc. quotations
