Supercomputers which can analyse blood samples and predict which patients are likely to become seriously ill could save tens of thousands of lives a year，it was revealed last night，according to The Daily Express.
The artificial intelligence(AI) system，developed at University College London and set to be piloted in NHS hospitals later this year，will screen “at risk” patients so doctors can take early action to prevent death or serious illnesses.Prof.Young，a consultant surgeon at Southend University Hospital，said，“I am so excited about this form of technology.”Instead of people getting sick or dying because they are not picked up in time，this will allow us to step in earlier which will save lives and an enormous amount of money.“I think the potential of AI in healthcare like this is as big as the Industrial Revolution was—and signals a completely new example in the way we manage healthcare.”
The technology is the brainchild of Dr. Vishal Nangalia，a consultant at the Royal Free Hospital in London.He used AI to analyse a billion stored blood samples from 20 different UK hospital trusts dating back up to 12 puters assess blood test results by picking up subtle changes in red and white blood cells，suggesting a patient is going downhill.
He found the technique forecast outcomes of patients with kidney problems with up to 95 per cent accuracy.Traditional methods highlighting serious patient concerns picked up as few as 16 percent of patients who went on to die.“This gives us the opportunity not only to save lives but to prevent serious illnesses，making the health service not only safer but more efficient.” Prof.Young said，“Instead of waiting for people to get worse，we will be able to treat them earlier.”

3．Why did Prof. Young mention the Industrial Revolution
A．To show the influence of AI.
B．To stress the importance of health care.

Microsoft has developed a new smartphone app that interprets eye signals and translates them into letters，allowing people with motor neurone disease to communicate with others from a phone.
The GazeSpeak app combines a smartphone's camera with artificial intelligence to recognize eye movements in real time and convert them into letters，words and sentences.
For people suffering from ALS(渐冻症)，also known as motor neurone disease，eye movement can be the only way they are able to communicate.
“Current eye tracking input systems for people with ALS or other motor impairments are expensive，not robust under sunlight，and require frequent re calibration(重新校对) and substantial，relatively immobile setups，” said Xiaoyi Zhang，a researcher at Microsoft who developed the technology.
“To mitigate the drawback，we created GazeSpeak，an eye gesture communication system that runs on a smartphone，and is designed to be low cost，robust，portable and easy to learn.”
The app is used by the listener by pointing their smartphone at the speaker.A chart that can be stuck to the back of the smartphone is then used by the speaker to determine which eye movements to make in order to communicate.
The sticker shows four grids of letters，which each correspond to a different eye movement.By looking up，down，left or right，the speaker selects which grids the letters they want belong to.The artificial intelligence algorithm(计算程序) is then able to predict the word or sentence they are trying to say.
5．Who is the smartphone app designed for
A．People with motor eye disease.
B．People suffering from eye communication.
C．People with problems in intelligence.
D．People suffering from motor neurone disease.
6．The underlined word “mitigate” in the fifth paragraph probably means ．
A．relieve B．get rid of
C．remove D．find
7．According to the text， ．
A．for people suffering from ALS，eye movement is one of the best ways to communicate
B．a new communication system that runs on a smartphone is designed to be immobile
C．the speaker could use the app by pointing their smartphone at the listener
D．the artificial intelligence algorithm will translate sentences for speakers

Eyesight plays a very important role in our daily life.Every waking moment，the eyes are working to see the world around us.Over forty percent of Americans worry about losing eyesight，but it's easy to include steps into our daily life to ensure healthy eyes. 1 ：
·Schedule yearly exams.Eye care should begin early in life.Experts advise parents to bring babies 6 to 12 months of age to the doctor for a careful check.The good news is that millions of children now can have yearly eye exams and following treatment，including eyeglasses.
·Protect against UV rays(紫外线)．Long term stay in the sun creates risk to your eyes.No matter what the season is，it's extremely important to wear sunglasses. 2 ．
·Give your eyes a break.Two thirds of Americans spend up to seven hours a day using computers or other digital products. 3 ．Experts recommend that people practice the 20/20/20 rule：every 20 minutes，take a 20 second break and look at something 20 feet away.
· 4 ．As part of a healthy diet，eat more fruit and vegetables each day.Vitamins(维生素) C and E help protect eyesight and promote eye health.
·Practice safe wear and care of contact lenses(隐形眼镜)．Many Americans use contact lenses to improve their eyesight.While some follow the medical guidance for wearing contact lenses，many are breaking the rules and putting their eyesight at risk. 5 ．Otherwise，you may have problems such as red eyes，pain in the eyes，or a more serious condition.

F．Always follow the doctor's advice for appropriate wear
G．This frequent eye activity increases the risk for eye tiredness
【语篇解读】 这是一篇说明文。文章指出如果不想近视，保持眼睛的良好状态的话，可以遵循五个建议。一、每年检查；二、阻止紫外线照射；三、让眼睛多休息；四、多吃点维生素以保证眼睛良好的状态；五、练习安全地佩戴隐形眼镜及其妥善保存。
1．B [在说明文文体中，第一段一般起到总领全文的作用，接着文章提出了五个保护视力的建议，故第一段中需要一句总起全文的句子，B选项为总领性句子。故B项正确。]
2．C [文中第三段提到可以戴墨镜阻挡紫外线。在段末处需一句总结性语句。C选项中的代词they指代的是前文中提到的sunglasses，故C项正确。]
3．G [文中第四段提到2/3的美国人一天使用电脑或其他数字产品的时间超过了7小时。而文中给出第三个建议是让眼睛休息一下，说明长时间使用电脑对眼睛是有损伤的。G选项中提到的“this frequent eye activity”指的是长时间使用电脑。故G项正确。]
4．D [根据第五段内容，维生素C、E都能保护人们的视力，维护眼睛的健康。可以看出该段的关键词为vitamins，故D项正确。]
5．F [文中最后一段提到“While some follow the medical...putting their eyesight at risk.”有一些人会遵守医嘱进行正确地佩戴隐形眼镜，但仍有一部分没有遵守医嘱的人，他们就可能面临视力上的危害。因此要时刻遵守医嘱，故F项正确。]

【语篇解读】 这是一篇说明文。文章指出如果不想近视，保持眼睛的良好状态的话，可以遵循五个建议。一、每年检查；二、阻止紫外线照射；三、让眼睛多休息；四、多吃点维生素以保证眼睛良好的状态；五、练习安全地佩戴隐形眼镜及其妥善保存。
1．B [在说明文文体中，第一段一般起到总领全文的作用，接着文章提出了五个保护视力的建议，故第一段中需要一句总起全文的句子，B选项为总领性句子。故B项正确。]
2．C [文中第三段提到可以戴墨镜阻挡紫外线。在段末处需一句总结性语句。C选项中的代词they指代的是前文中提到的sunglasses，故C项正确。]
3．G [文中第四段提到2/3的美国人一天使用电脑或其他数字产品的时间超过了7小时。而文中给出第三个建议是让眼睛休息一下，说明长时间使用电脑对眼睛是有损伤的。G选项中提到的“this frequent eye activity”指的是长时间使用电脑。故G项正确。]
4．D [根据第五段内容，维生素C、E都能保护人们的视力，维护眼睛的健康。可以看出该段的关键词为vitamins，故D项正确。]
5．F [文中最后一段提到“While some follow the medical...putting their eyesight at risk.”有一些人会遵守医嘱进行正确地佩戴隐形眼镜，但仍有一部分没有遵守医嘱的人，他们就可能面临视力上的危害。因此要时刻遵守医嘱，故F项正确。]
