Parents usually teach their children how to cross the street safety, by looking both ways for cars.1. The city of Honolulu, Hawaii wants everyone to learn that lesson.
2.Beginning on October 24, you will be fined from ＄ 15 to ＄ 99 if you step into a Honolulu street while looking at your phone. Honolulu is the first major U.S. city to ban what is called “distracted walking”. It recently passed a law in a seven to two vote. The law says, “No pedestrian shall cross a street or highway while viwing a mobile electronic device.’ 3.
The law includes all electronic devices with screens: cellphone, tablets, gaming devices, digital cameras and laptop computers.4. Pedestrians may use such devices in the street to call emergency services and rescue workers, such as firefighters and police officers.
Pedestrian deaths have been increasing as the use of cellphones rises. The Governors Highway Safety Association, or GHSA, says pedestrian deaths in the United States increased 25 percent 2010 and 2015. That trend continued in 2016 with the number of pedestrian deaths rising to almost 6000, 11% higher than in 2015.
5.The state of Washington was the first to outlaw distracted driving back in 2007. Now, 46 other states as well as D. C. , Puerto Rico, Guam and the U. S. Virgin Islands, have laws against texting while driving.
If you etill want to text while walking, you could avoid being fined in Honolulu by using a voice-controlled digital assistant such as Siri or Google Assistant. Or you could just wait until you are again, safely, off the street.
A. The law does permit an exception.
B. Other U. S. cities may follow Honolulu
C. But do they also teach them to put away their cellphones?
D. Texting while crossing the street will soon be banned in the city.
E. Do you like Honolulu’s new law that bans texting while walking?
F. In other words, do not look at a screen when you cross the street or you could be fined.
G. The law’s creator hope it will lower the number of people hit and killed by cars in the city.
Getting stitched(缝合) up by Dr. Robot may one day be reality. Scientists have created a robotic system which did just that in living animals without a real doctor pulling the strings. Much like engineers are designing self-driving cars, the medical research is part of a move toward autonomous surgical robots, removing the surgeon’s hands from certain tasks that a machine might perform all by itself.
Doctors wouldn’t leave the bedside they’re supposed to watch. Plus they’d handle the rest of the surgery. In small tests using pigs, the robotic arm performed at least as well, and in some cases a bit better, as some competing surgeons in stitching together intestinal(肠的) tissue. “The purpose wasn’t to replace surgeons, ”said Dr. Kim who led the project. “If you have all intelligent tool that works with a surgeon, can it improve the outcome? That’s what we have done.”
If you’ve heard about machines like the popular Da Vinci system, you might think robots already are operating. Not really. Today many hospitals offer robot-assisted surgery where surgeons use the machinery as tools that they control by hand to operate through tiny openings in the body. But robot-assisted surgery has been controversial, as some studies have shown it can bring higher costs without better outcomes.
Kim’s team at Children’s Sheikh Zayed Institute invented the new STAR system—it stands for Smart Tissue Autonomous Robot—works sort of like a programmable sewing machine. They added sensors to help guide each stitch and tell how tightly to pull. But the approach wasn’t perfect. In the living animals, the robot took much longer and made a few stitching mistakes while the surgeon sewing by hand made none. Kim said the robot can be sped up. He hopes to begin human studies in two or three years.

Recently a study，led by Pedro Hallal of the Federal University，suggests that nearly a third of adults，31%，are not getting enough exercise. That rates of exercise have declined is hardly a new discovery. Since the beginning of the industrial revolution，technology and economic growth have helped to create a world in which taking exercise is more and more an option rather than a necessity. But only recently have enough good data been collected from enough places to carry out the sort of analysis Dr. Hallal and his colleagues have engaged in.
There are common themes in different places. Unsurprisingly，people in rich countries are less active than those in poor ones，and old people are less active than young ones. Less obviously，women tend to exercise less than men—34% are inactive，compared with 28% of men. But there are exceptions. The women of Croatia，Finland，Iraq and Luxembourg，for example，move more than their male countrymen.
Malta wins the race for most slothful country，with 72% of adults getting too little exercise，and Swaziland and Saudi Arabia are in close behind，with 69%. In Bangladesh，just 5% of adults fail to exercise enough. Surprisingly，six Americans in ten are active enough according to Dr. Hallal’s study，compared with fewer than four in ten British.
These high rates of inactivity are worrying. Human beings seem to have evolved to benefit from exercise while deliberately avoiding it whenever they can. In a state of nature it would be impossible to live a life that did not provide enough of it. But that is no longer the case. Actually lack of enough activity these days has nearly the same effect on life span as smoking.

When I moved to Senegal in 2007 to work for a charity organization, the first thing I did was to hit the streets. Dakar, the capital, leans out into warm Atlantic wind. It has a relaxing atmosphere that makes it a favorite destination.
Not far from the city center, it also has one of Africa’s biggest slums(贫民区)and its share of beggars. Street kids would tail me, begging. During a previous trip to Senegal, I was once cheated by a man. I'd wondered for years whether to give money to beggars in West Africa.
Near my apartment, I passed a group of young men in wheelchairs whom I took to be beggars. Head down, I walked by them quickly. As the months went by, I'd often come across them. I’d often see them at an outdoor basketball court near my office. They’d sit on the ground with their chairs upside down, tightening and adjusting wheels, waiting until the other guys left so they could play.
I'd stay and watch them warm up. They played with speed, rolling down the court as fast as I could run. A few weeks later I introduced myself to them with the help of Mafall, who was one of the guys and could speak a little French. I started spending more time with them and eventually became something like an assistant coach.
The players quickly grew on me. I started referring to them as “my guys” to my colleagues. It was the most fun I’d had since I got to Dakar. Life on the street had made my players strong and they didn’t back down easily. I was proud of them.
Toward the end of the season, Mafall invited me to where he lived—found many of the players there, with their wives and children. I learned that most of them were born with disabilities. As Mafall and I chatted, I knew something had changed. They were no longer beggars. They were basketball players, my guys, and my friends.

A. To be afraid of being recognized by them.
B. To prevent himself from being stolen.
C. To be afraid of being cheated by them.
D. To be careful enough to find his way home.
3.Why did the author call the disabled young men “my guys”?
A. They often played tricks on the author.
B. They were loved by the author.
C. They used to cheat others when begging.
D. They always quarreled while training.
4.What is the whole text mainly about?
A. The author refused to be cheated by beggars in Dakar.
B. The author helped the locals in Senegal out of poverty.
C. The author coached the young men in Senegal to play basketbal1.
D. The author helped to change some disabled young men in Dakar.
