吉林毓文中学 姜晓琳
I. Lead-in
We depend on energy to do many things in our daily life. Can you list some sources of energy?
Sources of energy
coal natural gas oil non-renewable
wind power hydro-electric power solar energy tidal energy geothermal (地热的) energy renewable
Non-renewable resources will be exhausted one day, so what can we do to deal with this problem?
Title:
II. Read for main idea
Main idea:
On May 28, the experimental advanced superconducting tokamak (EAST), or the“Chinese artificial sun”, set a new world record after running at 120 million C for 101 seconds.
Type of writing:
news report
III. Read for questions
1. Compared with the record set by South Korea on Dec 28, what is the Chinese artificial sun like in terms of time and temperature?
2. What is the purpose of EAST?
3. What are the advantages of nuclear fusion compared to nuclear fission?
4. What does Li Jiangang's comment mean?
5. What is the ultimate goal for EAST?
1. Compared with the record set by South Korea on Dec 28, what is the Chinese artificial sun like in terms of time and temperature?
The Chinese artificial sun runs for a longer time (101 seconds) at a higher temperature (120 million C).
2. What is the purpose of EAST?
It is designed to replicate (复制) the nuclear fusion process that occurs naturally in the sun and stars to provide almost infinite clean energy through controlled nuclear fusion.
3. What are the advantages of nuclear fusion compared to nuclear fission?
Firstly, the fuel for nuclear fusion is abundant in seawater.
Secondly, the process of nuclear fusion doesn’t harm the environment.
4. What does Li Jiangang's comment mean?
He expressed his ambition to make use of the power of nuclear fusion and his pride in China.
5. What is the ultimate goal for EAST?
The ultimate goal is to keep the temperature at a stable level for a long time.

Revision of the attributive clause
Find the attributive clauses in the following sentences.
1. The natural resources that human beings depend on for survival, …
2. It is designed to replicate (复制) the nuclear fusion process that occurs naturally in the sun and stars to provide almost infinite clean energy through controlled nuclear fusion, …
3.It’s more like a future technology that’s critical for China’s green development push, …
4. Unlike nuclear fission (核裂变) power plants, which split atomic nuclei (原子核), nuclear fusion merges (融合) atomic nuclei to potentially create huge amounts of cheap and clean energy.
5. … without emitting (排放) any pollutants that harm the environment.
6. However, as the Chinese proverb goes, a journey of a thousand miles begins with a single step.
VI. Thinking
Although our country is striving to develop renewable energy resources, we still need to do something to reduce energy waste.
What measures do you think we should take to reduce energy waste?
A small act can make a big difference in the world!
Thank you!
