15、he usage of genome editing?1.to increase the human resistance to colds and flus2.to make people taller,to help their muscles develop faster,to sharpen all of their senses or to make them more intelligent.3.to select specific characteristics for children before they are born,creating designer babies.

18、pite the public argument over this technology,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.What do you think of“designer babies”?Post-readingI dont thin

19、k 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”become the norm,the diversity level will drop.Over time

20、,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 us,but interfering with our natural evolution could result in di

22、 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

23、 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.In a nutshell566Homework:检查周二发的五篇语法是否完成检查周二发的五篇语法是否完成 KKL P56&59 早自习安排：早自习安排：1.word list 2.Reading 3.7.40 开始听写（听写找班主任要开始听写（听写找班主任要word文档）文档）587Homework:KKL P56&59 早自习安排：早自习安排：1.word list 2.Reading 3.7.40 开始听写（听写找班主任要开始听写（听写找班主任要word文档）文档）
