Is Medicine the right major for you
President Xi said since the COVID-19 outbreak, a great number of medical workers have raced against time and fought tenaciously against the virus at the frontlines. They have made significant contributions in fighting the epidemic, and demonstrated the noble spirit of giving priority to saving lives with total devotion and ultimate love.
Medical professionals work hard to keep us healthy. Look at the pictures below and discuss the following questions in pairs.
A surgeon performs operations.
A physician is trained in general medicine.
A chemist prepares and sells medicines in a shop.
A dentist specializes in the care of people’s teeth.

What do you know about genes
A gene is a small section of DNA which controls a particular quality in a living thing that has been passed on from its parents.

Introduction
Para.1: Genome editing brings many exciting possibilities.
Main body
Para.2:
Para.4:
Para.5:
Conclusion
Genes play a critical role in shaping our lives.
Para.3:
Genome editing can help with disease treatment and prevention.
Many people are concerned about how to use genome editing appropriately.
Despite the public argument, genome editing is one of the greatest inventions in the history of science.

Step 2 Careful Reading
Para.2
Main Idea. Aspects
Genes play a critical role in shaping our lives. The of eyes and of math.
Make us and .
Helps determine and affects our chances of .
colour
our talent
grow
develop
lifespan
contracting certain diseases
Fill in the blank
1. What information does our personal genome carry
It carries all the information needed to make us grow and develop from the colour of our eyes to our talent for maths; it also contains information that helps determine our lifespan and affects the chances of contracting certain diseases.
Para.2
3.How might genome editing make it possible to prevent diseases from developing
Para. 3
By correcting abnormal genes early on.
2.How can geneticists make changes to the genome
By correcting, adding, deleting replacing specific parts of the genetic material.
4. What is a “designer baby”
Para. 4
A “designer baby” is a baby whose characteristics have been specifically selected before it is born.
5 .What dose the lecturer compare uncontrolled genome editing to
A car out of control.
Step3 Brainstorming
What other characteristics will you select
step4 Critical thinking
A Chinese researcher, He Jiankui, shocked the world two weeks ago when he revealed that the world’s first genetically edited babies had been born. Jiankui claimed to have edited embryos(胚胎) before implanting(移植) them into the mother.
Jiankui used a easy gene-editing technology to disrupt the gene for CCR5. He claimed that disruption of CCR5 would ensure that these babies would be protected from contracting HIV infection.
Since his bold announcement via YouTube, the scientific community at-large – both in the United States and in China – has strongly denounced this work as deeply unethical and dangerous.
We should use genome editing appropriately. Without appropriate controls, genome editing could be as dangerous as a car out of control.
Thank you.
