summary
first two paragraphs successfully attract audiences’ attention by using a poetic comparison between planet and human body, then gave us a news of Nobel prize issue in this year.
middle 11 paragraphs introduce how they carry out experiment and what they learned from the results. These three scientists used fruits flies to isolate a gene that controls the rhythm of living organism’s daily life. We don’t care about details in their work,
last 13 paragraphs use new knowledge to guide people’s sleep habit ,and give the terrible insight body changes causing of sleep deprivation. And list several diseases that may easily end your life.
for a very long time, people tend to believe it is the light that influence plants’ daily rhythm of life. the 2017 Nobel prize in physiology and medicine was awarded to three scientists jointly who used fruit flies to isolate a gene that controls the rhythm of a living organism’s daily life. It is the first time that we obtained scientific proof to elucidate that all living organisms contain a tiny body clock influencing our daily rhythm of life. This tiny clock is crucial to human health.
这篇文章主要介绍了实验组成，果蝇实验发现控制时间的主基因和作用机理，哺乳动物此类基因表达的主要集中区域，并以此说明光线对睡眠的影响。通过分析实验得到新的知识：此时钟基因影响身体各器官的工作状态，并分析了睡眠不足所导致一些疾病，给出一些建议。最后例举了海军和青少年作息制度的改变
learned
《黄帝内经》有了科学依据，而不只是经验总结
theoretical proof not just experience conclusion
Huangdi Neijing, a traditional Chinese medical work, was proved scientific indicating that it is not just a summary of experience.
2.
睡眠不足或是不规律导致肥胖／高血压／器官加速衰老的重要原因
sleep deprivation or irregularity account for obesity, high blood pressure, heart disease, organ failure and so on, if you would like to live longer, please obey the regulation of circadian rhythm.
3.
避免作息不规律，保证充足睡眠
Modern lifestyle will lead to long-time health consequences by messing the natural circadian cycle.so we should avoid irregular sleep patterns and guarantee enough rest on the right time.
4.we always confuse about why the doctor perform cardiac surgery in the afternoon, evidence supported by this study shows that blood pressure in the morning is highest during one day.
5.I believe that many people would like to know if this master gene will change to adapt to modern life style several centuries later, and what would happen cause of this change.
好奇是否未来的人的这种基因。。。
修改会怎么样？
the article is engaging or informative?
both
It tell us the truth of sleep and give us some advice, it is very useful for us nerve graduate students to keep healthy and not to die early.It is informative because of the writer not only describe the new discovery but also apply new knowledge into life and work for trying to explain the actual harm did by sleep deprivation.
a problem? A solution?
it put a common problem of not just in western society but also in east society, and use the new discovery and analyzation to give us advice
