Everyone knows that walking is one of the best means of exercise for health, so physicians often recommend 150 minutes a week. But that’s a measure of volume (量). What about the walking speed? Does that make a difference? A recent paper indicates the answer may be yes.
Previous research had only focused on total amounts of exercise in minutes or steps. A team of experts in Sydney looked at whether people who walked similar distances but at different speeds gained more or less health benefits
The researchers studied 11 English and Scottish population-wide reports that included more than 50,000 regular walkers with an average age of late 40s. The walkers were grouped according to four walking speeds: slow, average, brisk(轻快的) and fast. Lastly, the researchers figured out the death( from heart disease and cancer) rate during an average follow-up period of 9.2years.
New researchers showed marathoners had less arthritis(关节炎) than non-runners.
Participants who walked at an “average” speed, as opposed to ” slow ” , had a 20 percent lower risk of death. Those walking at a “ brisk ” or “ fast ” pace enjoyed an additional 4 percent lower death rate. While the best speeds vary with one’s own age and fitness, a pace below 20 minutes per mile is considered average, and below 18 minutes per mile is considered brisk. All the benefits came from lower heart-related deaths. Walking pace had no effect on cancer rates.
“Our paper is the first paper to keep apart walking pace from the physical activity volume ,”
Explained Emmanuel Stamatakis , a professor of the Charles Perkins Center. “We also took steps to role out ( 排除 ) the possibility that the slow walkers were in poor health to begin with.”
“Walking more is better than walking less. But don’t fall into the trap of thinking that any walk improve health. Keep out of the ‘ slow ’ zone. Make sure you’re putting some effort into your walk”, Stamatakis noted. “ An appropriate effort for those in a comfortable walking routine might be slightly out of breath.”
When you’re short of time, simply walk faster to increase the pay-off. “ A faster pace means you are challenging yourself to make adaptations for better health and fitness,” said Stamatakis.

Next time you go shopping, keep in mind that there may be hidden cameras analyzing your habits. According to a 2015 survey of 150 managers from Computer Services Corporation, a quarter of British shops use facial recognition software to collect data on shopper behavior.
With concerns that face-recognition cameras“ are kind of invasive(冒犯的)”, British analysis firm Hoxton Analytics has come up with a new way of measuring footfall (客流)—by filming people's shoes. The technology can collect a large amount of personal information. "We have cameras at 50 cm off the ground and they point down so they are less invasive than facial recognition," Duncan Mann, Hoxton's officer said.
As modern cities get fuller—70 percent of the population will live in urban areas by 2050—cameras and other technologies are taking over public spaces and collecting our data. Their purpose is to keep people safe, provide efficient services and prevent disasters and crimes.
But some are not happy with the cameras as far as their privacy(隐私) is concerned. "Very few of us have any real concept of what data smart cities are gathering," said Renate
Samson.
We begin giving away data as soon as we wake up. When we enter the transport system, we are giving away even more details about ourselves through smart cards, mobile phones or credit cards.
Nick Millman, director at a consulting firm thinks statistics are the key to the privacy concern. He used the example of Google Maps, which is to monitor the flow of traffic in Stockholm. He explained, "It is basically adding privacy controls to statistics so that you only see the data you need to know about". In this case, Google gets enough data to improve traffic but not so much that it shows individual journey patterns.

3.According to the author, cameras in modern cities_______.

4.What is Renate Samson's attitude toward the rise of smart cities?
A. Worried.
B. Optimistic.
C. Confused.

My First Marathon（马拉松）
A month before my first marathon, one of my ankles was injured and this meant not running for two weeks, leaving me only two weeks to train. Yet, I was determined to go ahead.
I remember back to my 7th year in school. In my first P.E. class, the teacher required us to run laps and then hit a softball. I didn’t do either well. He later informed me that I was ＂not athletic＂.
The idea that I was ＂not athletic＂ stuck with me for years. When I started running in my 30s, I realized running was a battle against myself, not about competition or whether or not I was athletic. It was all about the battle against my own body and mind. A test of wills!
The night before my marathon, I dreamt that I couldn’t even find the finish line. I woke up sweating and nervous, but ready to prove something to myself.
Shortly after crossing the start line, my shoe laces(鞋带) became untied. So I stopped to readjust. Not the start I wanted!
At mile 3, I passed a sign: ＂GO FOR IT, RUNNERS!＂
By mile 17, I became out of breath and the once injured ankle hurt badly. Despite the pain, I stayed the course walking a bit and then running again.
By mile 21, I was starving!
As I approached mile 23, I could see my wife waving a sign. She is my biggest fan. She never minded the alarm clock sounding at 4 a.m. or questioned my expenses on running.
I was one of the final runners to finish. But I finished! And I got a medal. In fact, I got the same medal as the one that the guy who came in first place had.
Determined to be myself, move forward, free of shame and worldly labels(世俗标签), I can now call myself a ＂marathon winner＂.
1.A month before the marathon, the author ____________.

C.made up his mind to run D.lost hope

A.To acknowledge the support of his teacher.

D.To share a precious memory.
3.How was the author’s first marathon?
A.He made it. B.He quit halfway.
C.He got the first prize. D.He walked to the end.
4.What does the story mainly tell us?
A.A man owes his success to his family support.
B.A winner is one with a great effort of will.
C.Failure is the mother of success.
D.One is never too old to learn.

A friend of mine named Paul received an automobile from his brother as a Christmas present.
On Christmas Eve when Paul came out of his office, a little boy was walking around the shiny new car, admiring it. "Is this your car, Mister?" he asked.
Paul nodded. "My brother gave it to me for Christmas." "The boy was astounded. "You mean your brother gave it to you and it didn't cost you anything? Boy, I wish..." He hesitated.
Of course Paul knew what he was going to wish for. He was going to wish he had a brother like that. But what the lad said jarred Paul all the way down to his heels.
"I wish," the boy went on, "that I could be a brother like that” Paul looked at the boy in astonishment, then impulsively he added, "Would you like to take a ride in my automobile?"
"Oh yes, I'd love that."
After a short ride, the boy turned and with his eyes aglow, said, "Mister, would you mind driving in front of my house?"
Paul smiled a little. He thought he knew what the lad wanted. He wanted to show his neighbors that he could ride home in a big automobile. But Paul was wrong again. "Will you stop where those two steps are?" the boy asked.
Paragraph1:
He ran up the steps.
