As artificial intelligence (AI) systems become more subtle, we can expect them to be used more often in the world of human medicine and healthcare. AI is designed to imitate the human brain in decision making and learning, so with the computing power to learn tasks in days or even hours, it is possible to create medical AIs that rapidly outperform doctors in certain tasks.
Most of the AI systems working in medicine employ smart algorithms ( 算 法 ), with the machine and deep learning techniques, and are supported by speech recognition and computer or machine vision to make their decisions. It will be some time before researchers can develop artificial general intelligence systems capable of abstracting knowledge and developing their own experiences to share with other AIs. But firms like Microsoft, Google, Apple,
IBM and Facebook are preparing themselves up to deliver the most advanced AI personalized healthcare possible for patients around the world.
Data plays a hugely important role in helping AI systems learn about human medicine. AI systems are trained on large data sets gathered from real-life cases. Providing amounts of detailed patient information is a decisive factor for their success.
One of the most important areas for influencing global health is in the field of epidemiology ( 流行病学).
Predicting disease outbreaks can save millions of lives by having resources ready should the worst happen. Another field where medical AIs are making rapid advances is in diagnostics. Doctors base a lot of decisions on information from X-ray, CT and MRI images. Speeding up diagnoses from patient scans can rapidly improve patient care and outcomes.
Cardiologist (心脏病医生) Rima Arnaout developed an AI that beat human experts at correctly interpreting echocardiograms by 92 percent to 79 percent. She said that despite the result there is no hope of AI replacing human doctors any time soon. "As cardiologists, we read the images and then go see the patient," she said. "So we’re both reading images and practicing medicine. I don't think that the second piece will be taken over so quickly."
1.The purpose of this text is to introduce ________.
A.the speech recognition of AI systems
B.the computer vision of AI systems
C.the rise of AI systems in medicine
D.the development of AI in tech firms
2.What is the key to making medical AI systems successful?
A.Arriving at decisions.
B.Providing patient data.
C.Predicting disease outbreaks.
D.Speeding up diagnoses.
3.What can we infer from Rima's words?
A.She prefers practicing medicine to reading images.
B.AIs do better than cardiologists in seeing patients.
C.She is confident in the irreplaceable role of human doctors.
D.AIs are unable to read images with current technology.

No video games are allowed after 10 pm. It is not allowed to play games for more than 90 minutes on non-holidays. No more than 400 yuan per month is allowed to buy virtual weapons and costumes.
The Chinese government has issued new regulations aimed at controlling teenager’s addiction to video games. Some officials believe that this problem is the reason why more and more young people are suffering from myopia (近视) and poor learning. The rules forbid users under the age of 18 from playing between 10 pm and 8 am. The rules demand that they shouldn’t play more than 90 minutes on non-holidays and more than 3 hours on weekends and other holidays.
Officials have taken stronger measures to monitor large technology companies and promote them to help spread the advocated cultural values. The official media regarded some games as “poisons” and banned some violent games. In addition, minors (未成年人) must use real names and ID numbers when they log into the game. These regulations also limit the a-mount of money that teenagers can use to purchase virtual items such as weapons, clothing, and pets through the app.
Analysts said that these regulations have been largely predicted by the industry and are unlikely to affect its earnings. However, young gamers may also find ways to bypass (绕开) the rules, such as using the parent’s phone number and ID number. “There will always be something imperfect,” said Daniel Ahmad, senior analyst at Niko Partners. However, he added that thanks to the regulations, China is now one of the most regulated video game markets in the world.
Yang Bingben is the owner of an industrial technology company. He noticed that his son often plays games that don’t require networking and is difficult to control. “We have something new to replace the games,” he said, “our thinking should be to build more stadiums, such as football stadiums and basketball courts.”
1.The new regulations will help Chinese teenagers with their ________.
A.intelligence B.personalities
C.study and eyesight D.constitutions and morals
2.What did Daniel Ahmad think of the regulations?
A.They are adjustable. B.They are effective.
C.They are creative. D.They are worthless.
3.What can be inferred from Yang Bingben’s words?
A.Teenagers are spending more time in the stadiums.
B.Football and basketball will be popular with teenagers.
C.Getting rid of the addiction to video games is impossible.
D.Doing sports helps prevent teenagers playing video games.
4.In which section of a newspaper can you read the text?
A.Literature. B.Education.
C.Fashion. D.Sport.

Between sports, games, and playing outside, there is lots of competition for kids’ time. Here are some ways they can still keep up their reading.
1.
Encourage kids to take five or ten minutes at the beginning of each day to read, before doing anything else. They can even set a timer (计时器). It’s always possible that they’ll want to keep going after their time is up.
Match books to activities
Know a child going to soccer camp? Connect him or her with sports stories by authors like Matt Christopher. 2. The Summer of May by Cecilia Galante is a moving story about a girl experiencing her own summer school.
3.
Encourage children to always carry a book with them. It sounds simple, but kids may be surprised to discover all the time during the day they have for reading — on the bus to camp, in a waiting room, or during breaks.
Have family reading time
Just as you set aside time for reading during the school year, ask families to devote 20 minutes a day to book. 4.
Set goals
Some kids will have no problem finishing reading four books in the summer. 5. Meet with kids to determine them.
A.Read for fun
B.Read over breakfast
C.Always carry a book
D.Have a student who’ll be in summer school?
E.Others may need to make sound plans, such as two books a month.
F.Every family member should read during this time, including Mom and Dad.
G.That means three months with books can make a difference in their vocabularies.
