Step Ⅲ Reading
T:OK.Now please open your books at Page 7.Look at Reading and Writing.Read each passage quickly and find out the answers to the following two questions on the screen.
(Teacher shows the following on the screen.)
1.What plan has helped Chinese scientists make many breakthroughs?
2.Which scientific fields are mentioned in the text?
(After a while,teacher checks the answers.)
T:Have you found the answers?
Ss:Yes.
T:Who’d like to answer the first question?
S4:The plan for “rejuvenating the nation by relying on science and education”.
T:Quite right.The other question?
S5:Exploring space,genetic research,computer engineering and medical science.
(Teacher writes the answers above on the blackboard.)
T:Nice work.Now,please read the passages again carefully,trying to understand them more exactly and pay attention to some detailed information.After that,work in groups to complete the chart after the passages according to what you’ve learnt from the text.After four minutes,I’ll check your answers.
Suggested answers:
Exploring space
Achievements:The Chinese space Agency has developed the highly successful Long March rocket series.
Importance:The rockets are used to prepare for the nation’s first manned space flight.
Genetic research
Achievements:Chinese scientists have completed mapping out their part of the international human genetic project.
Importance:It has proved that Chinese scientists are among the world’s best.It helps to solve the mysteries of life.
Computer engineering
Achievements:Chinese computer engineers have developed the supercomputer Shenwei.
Importance:The nation’s first humanoid robot has been built.
Medical science
Achievements:Scientists have been able to create a chemical element that can fight cancer cells.
Importance:The breakthrough makes the cure of deadly disease possible.
(After that,teacher deals with the language points.)
T:Nice work.I think you must have understood the text very well.Now,let’s learn some useful words and expressions.Please look at the screen.

(Teacher begins to play the tape.)
Step Ⅴ Writing
T:Well,up to now,we’ve read a lot about scientific achievements.Which words in the text can we use to describe scientific achievements?Prepare for a few minutes.Then I’ll collect them from you.
Suggested words:
significant,outstanding,breakthrough…
(Then teacher deals with Writing.)
T:Very good.Now,please look at the Writing part.You’ve been asked by the magazine Modern Science to help them choose the greatest scientific achievement ever.Write a short essay,telling them which achievement you have chosen and explaining why you think that it is the most important.Are you clear about what to do now?
Ss:Yes.
T:In order that you can write your essay better.You’d better read and study the tips at Page 8 carefully before writing your essay.You can begin now.If time permits,I’ll ask some students to read their essay to the rest of the class.A sample essay:
The publication of the detailed structure of 99% of the human genome is the culmination of one of the largest scientific undertakings in history.Initiated in 1990,the Human Genome Project involved the cooperative work of hundreds of scientists in 20 sequencing centres in countries including China,France,Germany,Great Britain,Japan and the United States.
The achievement is important.Not only has it given a glimpse into the extraordinary complexity of the structure of human DNA but it has also demonstrated the huge potential of cooperative scientific endeavour organized on an international basis.
Moreover,the project’s completion has already produced medical breakthrough,scientists assert that the achievement can assist research into cancers such as leukemia,and may also extend far beyond to the other deadly diseases.
Step Ⅵ Summary and Homework
T:Now let’s see what we’ve learnt in this class.First,we’ve read about some China’s significant achievements in science and technology.We know Chinese history is filled with great achievements,not only in the past,but also today.Science and technology makes a country richer and stronger.Science and technology also makes society develop and progress.Do you think so?
Ss:Yes.
T:Second,we’ve practised writing a persuasion essay.We can use some words to describe scientific achievement.Moreover,we’ve learnt some useful words and phrases such as put forward,announce…After class,please practise more to develop your ability to use English.So much for today.Goodbye.
Ss:Goodbye.
