1、Welcome to the unit & Reading (I)As we know, fitness matters. Can you name the benefits of keeping fit?Lead-in1.Make ourselves energetic. 2. Keep us in good health condition. 3. Get doctors away. 4. Keep a nice figure. 5. Build a strong body. 6. Keep your body at a proper weight. 7. Give you a good

2、mood. 8.Improve your will powerand physical strength. Welcome to the unitSince staying healthy is so crucial in life, who should we turn to if we get sick?Doctors, of course!1. What jobs are shown in the pictures? Write the letters in the boxes.bdcaWelcome to the unitWould you like to be a medical p

3、rofessional? Why or why not?Yes, I would like to be a medical professional. Medical professionals often have very specialized career fields, such as being a dentist, surgeon or chemist. Professionals in these fields help people live healthy lives by healing their diseases and even sometimes saving t

4、hem from death. For this reason, I believe that as a medical professional, I can contribute to society in an important way. Welcome to the unitNo, I would not want to be a medical professional. Working in that field is very challenging and requires someone who could cope with the constant pressure o

5、f worrying about whether they have made the correct decisions. Deciding suitable treatments may not always deliver the results that either the patient or the doctor has hoped for. So, even though I know that I can act responsibly, I dont think I could handle the pressure.Would you like to be a medic

Why is genes critical in shaping our lives?Because everything from the colors of our eyes to our talent for maths depends on gene.While-readingIt carries all the information needed to make us grow and develop. It also contains information that

10、helps determine our lifespan and affects our chances of contracting certain diseases.2.

What are the specific examples listed for the usage of genome editing?We will be able to use genome editing t

13、o increase the human resistance to colds and flus, to make people taller, to help their muscles develop faster, to sharpen all of their senses or to make them more intelligent. We will also be about to select specific characteristics for children before they are born, creating designer babies.Should

14、 we restrict our use of this technology to the treatment and prevention of disease?Should we prohibit geneticists from using it to enhance healthy bodies?Is the idea of designer babies a good thing?What consequences might it have?2. What are the questions that arise about how to use it appropriately

15、?We should put controls in place to make sure that genome editing will work to our advantage. 3. How can we keep the technology from running wild?What is the lecturers attitude toward genome editing?A. Disapproving B. Doubtful C. Neutral D. SupportiveDEvidence:Despite the public argument over this t

16、echnology, its possibilities have been creating much excitement throughout the entire medical community and beyond. Without doubt, genome editing is one of the greatest inventions in the history of science.Post-reading1. The lecturer mentions that one day we will be able to create “designer babies”.

17、 What do you think of “designer babies”?I dont think we should design babies unless it is because of serious physical or mental health concerns. There is no need to design a baby if its parents are perfectly healthy. Natural gene selection ensures diversity among our species, so if “designer babies”

18、 become the norm, the diversity level will drop. Over time, this could lead to the majority of people being born with similar intelligence levels, similar physical features and perhaps, even similar personalities. Humans could evolve into “super-beings”, which some people may believe to be good for

19、us, but interfering with our natural evolution could result in disaster. I dont think we should take the chance. 2. What controls can we put in place to make sure that genome editing will work to our advantage?Post-readingGovernments around the world should work together to make laws and regulations

20、 about when genome editing can and cannot be used. First, these laws and regulations should cover various aspects of genome editing, such as ethical issues and security, and they may have to be introduced at multiple levelsglobal, national and even regional. Second, genome editing equipment needs to

21、 be strictly controlled so that it does not get into the wrong hands. Finally, governments, scientists, stakeholders and the public need to work together to enforce appropriate usage of genome editing. The application of these laws regarding genome editing will only be successful if all parties concerned cooperate.pFinish B1 on P33.pSurf the Internet and learn more about genome editing.
