Personalized medicine changes conventional medicine which typically offers blanket recommendations and offers treatments designed to help more people than they bam but that might not work for you. The approach recognizes that we each possess unique characteristics, and they have an out size impact on our health.

Around the world, researchers are creating precision tools unimaginable just a decade ago: superfast DNA sequencing(排序); tissue engineering, cell reprogramming, gene editing, and more. The science and technology soon will make it possible to predict your risk of cancer, heart disease, and countless other illnesses years before you get sick. The work also offers prospects for changing genes in removing some diseases.

Last spring, researchers at the National Cancer Institute reported the dramatic recovery of a woman with breast cancer, Judy Perkins. The team, led by Steven Rosenberg, an immune(免疫的) treatment pioneer, had sequenced her cancer cells’ DNA to analyze the sudden change. The team also removed a sampling of immune cells and tested them to see which ones recognized her cancer cells' genetic faults. The scientists reproduced the winning immune cells by the billions and put them into Perkins to attack her cancer cells. More than two y cars later. Perkins, a retired engineer from Florida, shows no signs of cancer.

Thirty years ago, scientists thought that it would be impossible to understand our genetic rules and sequence the 3.2 billion pairs of different elements in our DNA. “It was like you were talking fairytales,” Kurzrock said. “The conventional wisdom was that it would never happen. Never And then in 2003, never was over.”

It took the Human Gene Project 13 years, roughly one billion dollars, and scientists from six countries to sequence one gene complex. Today sequencing costs about a thousand dollars. The latest machines can produce the results in a day. The technology, combined with advanced cell analysis, clarifies the astonishing biochemical variations that make every human body unique.

1. What can we know about personalized medicine?

文章大意:本文是一篇说明文。文章主要内容是关于目前医疗领域职业机会的增加,其中两个主要原因是人口老龄化和医疗服务的复杂化。虽然成为医生需要长时间的教育和工作,但是成为医疗助理是一个令人兴奋、安全和高薪的职业选择。医疗助理还可以选择接受额外培训成为护士或医疗从业者,或者接受行政培训成为大型医疗机构的办公室经理。医疗助理的职业领域提供了很多工作灵活性和个人成长的机会。

【推荐1】If you’ve found yourself thinking of a new job or a new career, don’t be upset.     1    

Job opportunities in health care are on the increase.     2     A much larger population of the elderly means a huge increase in demand for medical services and the people that provide them.

    3     Our health care is getting more and more complicated. And that means highly skilled people are needed to deliver the service. Put these two things together and you get higher salaries and more employees are demanded. We all know that doctors make big bucks(赚大钱). But, to be a good doctor, you must endure over 10 years of schooling and work amazingly long hours.

Fortunately, you don’t need to become a doctor to settle into an exciting, secure, and well-paid job. There are many opportunities available, and one of the best ways to get into the field is to be a medical assistant.     4     The position can be part-time or full-time. You can even just work in the evening and at weekends. Working conditions and benefits tend to be excellent, and you can manage to have a life outside of work as well.

Many medical assistants choose to take additional classes to become nurses and health care practitioners(执业医师). Some receive additional administrative training and become office managers for larger practices.     5    

A.Job is less for the old.
B.​The second reason is related to professional aspects.
C.This is due to two factors: Firstly, the American population is aging rapidly.
D.The field of medical assistants offers many options for job flexibility and personal growth.
E.Intelligent technology brings many employment opportunities to human beings nowadays.
F.Your first job as a medical assistant is a more rewarding career in the health care industry.
G.There is one field that’s predicted to grow steadily in the future: health care professionals.

【推荐2】The biomedical world is flooded in data. We have a lot of genomic information from mouse to human, precious health measurements from clinical tests, and a large amount of so-called real-world data from insurance companies and drugstores. Using powerful computers, scientists have carefully researched it with some fine results, but it has become clear that we can learn much more with an assist from artificial intelligence. Over the next decade deep-learning neural networks will likely transform how we look for patterns in data and how research is conducted and applied to human health. This special report explores the future of this new transformation.

Right now the biggest assumptions are being placed in the field of drug discovery, and for good reason. The average cost of bringing a new drug to market nearly doubled between 2003 and 2013 to $2.6 billion, and because nine out of ten fail in the final two periods of clinical tests, most of the money goes to waste. Every large drug company is working with at least one AI-focused start-up to see if it can raise the return on investment.

Machine-leaning algorithms(算法)can get through millions of chemical compounds, narrowing the choices for a particular drug target. Perhaps more exciting, AI systems—free by leading theories and biases—can identify entirely new targets by spotting tiny differences at the level of cells, genes or proteins between a healthy brain and one marked by Parkinson’s—differences that might avoid or even puzzle a human scientist.

That same sharp eyed ability is also being used to explain medical scans. Some systems can already discover early signs of cancer that might be missed by a radiologist or see things that are simply beyond human capacity—such as evaluating cardiovascular(心血管)risk from a retinal scan. The Food and Drug Administration is approving imaging algorithms at a rapid click. Other AI applications lie a bit further down the road.

Will the inefficiencies of today’s electronic health records (EHRs) be solved by smart systems that prevent prescribing mistakes and provide early warnings of disease? Some of the world’s biggest tech giants are working on it.

Despite fears that machines will replace humans, most experts believe artificial and human intelligence will work cooperatively. The bigger concern is a shortage of people with both biomedical knowledge and algorithm proficiency. If this human problem can be solved, the key to creating successful AI applications may depend on the quality and quantity of what we provide them with. “We rely on three things,” says the CEO of one deep-learning start-up. “Data, data and more data.”

1. Why do large drug companies work with AI-focused start-up?
A.Because it is required by the government to do so.
B.Because it helps to explore new medicine with others.
C.Because it saves costs for drug companies to explore AL.
D.Because it’s used to check if the return on investment can be increased.
2. What is the author’s attitude towards the changes that AI has brought to the field of medicine?
A.Positive.B.Negative.
C.Neutral.D.Unclear.
3. What would be the best title for this passage?
A.Why New Technology Will Change Our Life
B.How Artificial Intelligence Will Analyze Data
C.How Artificial Intelligence Will Replace Humans
D.How Artificial Intelligence Will Change Medicine

【推荐3】The number of new deaths from the novel coronavirus(新型冠状病毒)reported in Wuhan, Hubei province, by Monday reaching the lowest in 10 days can indicate a change, said Qiu Haibo, a member on the expert panel of the National Health Commission.

Qiu said in an interview with China Central Television on Tuesday that the number of new infections and new deaths is declining, which means that the measures adopted in the city have gradually taken effect. He said the critically ill patients were treated intensively . The 10 appointed hospitals with 8, 000 beds for critical patients had 1, 000 empty beds on Tuesday.

''Moreover, a large number of national medical teams have arrived in Wuhan since the beginning of February, bringing Wuhan's treatment level to a national standard , '' he said. ''In general, it can be said with caution and optimism that the treatment of critically ill patients has gradually shown its effect through the previous efforts, '' he said.

He said the declining number is also owing to more timely treatment since February when medical resources have become more sufficient. It may also be related to the nature of infectious diseases . As medical resources are becoming more and more sufficient and the country's medical strength is gathered in Wuhan, they are confident that the number of critically ill patients will continue to drop.

He added that the treatment has become more standardized and general patients can now receive more timely treatment to prevent them from becoming critically ill . The treatment concept has also changed from treating a single organ to multiple organs. ''A series of progress in treatment and knowledge can help reduce the proportion of severe illness and increase the recovery rate, '' he said.

1. What is not the factor contributing the reduced number of new deaths?
A.There are many more beds in hospitals in Wuhan.
B.Medical teams from across the country have come.
C.Diverse resources have become more sufficient.
D.The virulence becomes weak as it gets warmer.
2. Where can ''that the virulence may be decreasing as the disease passes from person to person'' be put in the passage?
A.①B.②C.③D.④
3. What is the best title of the passage?
A.Ill patients are treated intensively in Wuhan
B.Decline in new Wuhan deaths shows measures work
C.Treatment has become more standardized
