Summary

[1] The report of the live birth of twin baby girls with genetically engineered genomes caused an uproar around the world. 

[2] Some of the criticism focused on China's allegedly permissive research ethics. 

[3] Chinese scientists resent that characterization, but the incident has set off debate within the country over its regulation of biomedical research. 

[4] The researcher, He Jiankui of the Southern University of Science and Technology in Shenzhen, China, allegedly violated a provision in a regulation that came into effect in 2003, long before gene editing became a common research tool. 

[5] China's scientists and ethicists are now calling for new or revised regulations. 

[6] But some researchers fear a backlash provoked by one group that deliberately ignored existing regulations could result in new rules that will burden even ethical scientists.

标题：主语＝a CRISPR first。把For China放在句首，显然是“矛头”直指中国！

                 ［1］         主语＝The report of the live birth of twin baby girls with genetically engineered genomes

我不喜欢长主语。我也不觉得“the report”是最好的选择。我觉得“live birth”的live是“蛇脚”（多余的）。这次birth如果是“死的”，我们现在不会“热血沸腾”。

［2］         学习一下China's （比如 Zhang’s）

［3］         学习一下that characterization (not this, but that) 和the incident。

［4］         学习一下in Shenzhen, China, (两个逗号，都是我的朋友) 。 He Jiankui 是姓在先，说明他足够出名了。学习用long before。

［5］         有意思，用China's， 而不是Chinese。用for new or revised （regulations）， 说明作者不知道中国有没有regulations？

［6］         我不喜欢用But开头，但是（but），历史的潮流不是我能阻挡的。学习一下could result in。

你也可以参加讨论。
