4．Health is the thing that makes you feel that now is the best time of the year.
— Franklin P．Adams
健康是这样一个东西，它使你感到现在是一年中最好的时光。
——富兰克林·P.亚当斯
One of the most difficult things to accept about life is the fact that suffering is a part of it.People die，get sick，hurt each other and hurt themselves.One of the most important lessons I have learned is that it is very important to accept the bad with the good，the light with the dark and the pain with the joy.I have learned that without pain I wouldn't know joy.I have learned that because of things like illness and death it is that much more important to love and live life to the fullest.Great lessons are learned from terrible tragedies，tremendous growth takes place when we are pushed to our very limits，and although I don't necessarily like the “tough stuff” I am learning to live with it.
Early in the COVID19 pandemic (流行病)，scientists in China uploaded the virus's genetic sequence to genetic databases.A Swiss group then synthesized (合成)the entire genome and produced the virus from it—essentially teleporting the virus into their laboratory for study without having to wait for physical samples.Such speed is one example of how wholegenome printing is advancing medicine and other endeavors (努力，试图)．
Wholegenome synthesis is an extension of the booming field of synthetic biology.Researchers use software to design genetic sequences that they produce and introduce into a microbe，thereby reprogramming the microbe to do desired work—such as making a new medicine.So far genomes mainly get light edits.But improvements in synthesis technology and software are making it possible to print ever larger swaths(长条)of genetic material and to alter genomes more extensively.
