Pilates, yoga and the running machine get all the attention when it comes to popular ways to stay healthy.

There is, however, a more humble exercise that might not be so attractive, but has all the benefits — walking.

Certified fitness professional Jolynn Jaekel explains, “What I love about walking is that anyone can do it at any age and any fitness level. Plus, it is good for your heart, your head and your wallet.”

A recent report details the health benefits of walking. The report found that walking regularly to fulfill the 150 minutes of moderate physical exercise every week, recommended by the UK's chief medical officer, could save 37,000 lives each year. Scientists at the Lawrence Berkeley National Laboratory in California found that quick walking reduces the risk of heart disease more effectively than running. They observed participants aged between 18 and 80 over a six­year period and found that walking reduced the risk of heart disease by 9.3%, while running reduced it by 4.5%. And there is even more good news: 30 minutes of quick walking over five days could help you sleep easily, according to research by Oregon State University. The study by the university showed that walking helped participants sleep better and feel more alert during the day.

The sooner you get started, the sooner you'll notice the differences in your mind and body. So, go out for your 30­minute walk in a nearby park or green space.

The human body is a living machine, and, like all machines, it needs "fuel" （燃料） to supply it with energy．This is provided by the food we eat．But how much do we need to stay healthy?

The energy value of food is usually measured in calories．A calorie is the amount of heat required to raise the temperature of 1 kg of water by 1℃．The number of calories people need per day is different．Also, the number of calories you use at any one moment normally depends on the activity you are in．For example, you need more calories for standing than for sitting, more for running than for walking, and so on．

The energy in food is in the form of three kinds of chemical materials-carbohydrate（碳水化合物）, protein（蛋白质）and fat．Carbohydrate provides 3．8 Cal/gm, protein 4．0 Cal/gm, and fat 8．8 Cal/gm．Each food contains different amount of these materials, as the round pictures show．

1．The amount of calories supplied by equal amounts of milk, rice, and peanuts is the largest in the case of ________．

A．milk             B．rice               C．peanuts        D．rice or peanuts

2．Choose one statement from among A-D that agrees with the passage and the pictures above．

A．You need more calories for swimming than for mountain climbing．

B．Food contains energy in the form of carbohydrates, proteins and fuel．

C．Different people need different amounts of energy depending on their age, sex and the activities they are in．

D．3 grams of milk provides 16．6 calories because carbohydrate provides 3．8 Cal/gm, protein 4．0 Cal/gm and fat 8．8 Cal/gm．

3．This article mainly tells us ________．

A．all the energy is in food           B．the human body needs energy

C．the number of calories depends on your activity

D．we must only eat peanuts to get calories

C

As every computer owner knows, when their machines run a complex program they get pretty hot. In fact, cooling the processors can be expensive, especially when you're dealing with huge banks of computer servers. But what if that energy could heat private homes? A Dutch energy firm aims to do just that.

Data centers of large Internet firms, such as Google, Apple, Microsoft and others, contain thousands of computer servers. As they process information they generate enormous amounts of heat requiring cooling towers that dissipate it into the atmosphere.

A Dutch firm thinks paying for electricity to run the servers and then paying again to cool them is a waste of energy.

Boaz Leupe, CEO of the start-up Nerdalize, says it’s actually quite simple.

"We don't actually have to build the data center, which saves a lot of costs in infrastructure and we don't have the cooling overhead, plus that you have the environmental benefit, that the kilowatt hour you are using is used twice, once to heat the home and once to compute the clients task without the cooling overhead," says Leupe.

The company developed what it calls an e-Radiator, a computer server that also works as an alternative heating source. Leupe says that five Dutch homeowners are experimentally using them in their homes.

“We reimburse the electricity the server uses, and that we can do because of the computer clients on the other side, and, in that way, home owners actually get heating for free, and computer users don't have to pay for the overhead of the data center,” says Leupe.

One of the participants in the year-long experiment, Jan Visser, says the amount of heat produced by e-Radiator depends on the work being done by the server’s processors so it cannot be used as the primary source. But he is ready to try it.

“If it gives good enough warmth, you can use less of your existing central heating, and there is the chance for a home owner to pay less bills.”

Nerdalize says e-Radiators generate temperature of up to 55 degrees Celsius and could save up to $440 in annual heating costs.

1.Which one is true according to the passage？

A. It is expensive to deal with huge banks of computer servers.

B. A Dutch energy firm attempted to heat private homes.

C. Computer servers generate large quantities of heat.

D. The cooling tower is a waste of energy.

2.The underlined phrase “overhead” in the third paragraph probably means______.

A. daily cost B. fixture

C. forehead　 D. method

3.What is NOT true about e-Radiator according to the passage?

A. It is a computer server used as an alternative heating source.

B. It has been launched onto the market.

C.It is environmentally friendly.

D. It can save users’ money.

4.Which of the following can be the best title for the passage ?

A. A New Kind of Data Servers

B. Data Servers Could Heat Private Homes

C. How to Heat the Private Homes with Computers

D. An Alternative Heating Source

For all the technological wonders of modem medicine, health care-with its fax machines and clipboards(写字板)—is out of date. This outdated era is slowly drawing to a close as the industry catches up with the artificial-intelligence ( AI) revolution.

Eric Topol, an expert in heart disease and enthusiast for digital medicine, thinks AI will be particularly useful for such tasks as examining images, observing heart traces for abnormalities or turning doctors' words into patient records. It will be able to use masses of data to work out the best treatments, and improve workflows in hospitals. In short, AI is set to save time, lives and money.

The fear some people have is that AI will be used to deepen the assembly-line culture of modem medicine. If it gives a “ gift of time” to doctors, they argue that this bonus should be used to extend consultations, rather than simply speeding through them more efficiently.

That is a fine idea, but as health swallows an ever-bigger share of national wealth, greater efficiency is exactly what is needed, at least so far as governments and insurers are concerned. Otherwise, rich societies may fail to cope with the needs of ageing and growing populations. An extra five minutes spent chatting with a patient is costly as well as valuable. The AI revolution will also enable managerial accountants to adjust and evaluate every aspect of treatment. The autonomy of the doctor will surely be weakened, especially, perhaps, in public-health systems which are duty-bound to cut unnecessary costs.

The Hippocratic Oath(誓言) holds that there is an art to medicine as well as a science, and that “warmth, sympathy and understanding may outweigh the surgeon's knife or the chemist's drug”. There's lots of sense in it: the patients of sympathetic physicians have been shown to recover better. Yet as the supply of human carers fails to satisfy the demand for health care, the future may involve consultations on smartphones and measurements monitored by chatbots. The considerately warmed stethoscope ( 听诊器) ,placed gently on a patient's back, may become a relic of the past.

1.What's Dr Topol's attitude toward AI's coming into medicine?

A.Concerned. B.Doubtful. C.Optimistic. D.Cautious.

2.What does the author of the text attach more importance to?

A.Medical costs. B.National wealth.

C.Longer consultation. D.Greater efficiency.

3.Why is the Hippocratic Oath mentioned?

A.To prove the bright future of AI.

B.To show the advantage of a human doctor.

C.To explain medical equipment is more important.

D.To argue a human doctor performs as well as a robot.

4.What may be the best title for the text?

A.Health care and AI B.AI and its applications

C.Doctors and Patients D.Dr Topol and digital medicine
