1 . Aeron McQuillin, 18, Bailey Campbell, 17, and Billy Tarbett, 15, were on their way to a supermarket in Fonthill, Ontario, when they spotted a woman on the side of the road with smoke coming out of her car. They quickly found the problem and determined the car was too dangerous to drive.
The driver couldn’t afford a tow truck (拖车). So, Billy suggested that they push the car. The woman lives more than five miles away. Dan Morrison, who also stopped to help, told CNN the driver’s jaw dropped on hearing the teens’ offer. Bailey told CNN they just wouldn’t want to be stuck like that, so they insisted.
The three bought bottles of water and a speaker so they could “jam out” and started their journey. Morrison drove behind them with his hazard lights (双闪灯) on for safety. Baily said they faced several problems. The first was a big hill 300 yards from the start. Halfway through, they took a break and the battery died. They had to charge it just to get back into neutral (空挡位置).
After more than two and a half hours of pushing, they finally delivered the car back home. Bailey described the motorist as both thankful and amazed. They exchanged hugs, and everyone went home for some much-needed rest. The teens never got the woman’s full name.
Morrison took a couple of pictures of the teens, hoping to turn them into hometown heroes on social media. His Facebook post went viral, with positive comments coming in from as far away as Australia.

3 . Cities across America have set up bike-share programs as sustainable (可持续的) transportation alternatives to ease traffic jams. Yet despite these programs’ advantages and popularity, significant operational challenges remain.
Residential neighborhoods face shortages of bicycles in the morning rush hour, while business districts have a lack of bikes in the evening. What’s more, parking docks can be full at certain hours when riders have reached their destinations. Currently, many systems rebalance their bike supply using box trucks that reallocate dozens of bikes at a given time. This is a costly, time-consuming attempt that enlarges the systems’ carbon footprint. Thus, it is vital that rebalancing be as efficient as possible. With that in mind, my colleagues and I set out to develop advanced algorithms (算法) to deal with the novel challenges of bike-share operations.
One area to which our methods were applied was the Bike Angels program that our collaborators run in cities across the country. Initially, riders of Bike Angels earn points by renting or returning bikes at certain high-need stations.
In a study, we found that these fixed patterns cause inefficiencies when returns are incentivized (激励) in locations where they do not actually help with rebalancing.
The changes to operational patterns we made based on our algorithms can increase the efficiency of the incentives by around 15 percent. And importantly, this form of rebalancing comes with a much better carbon footprint than box trucks!
Our algorithms are applied for other purposes, too. For instance, by analyzing usage information, we were able to help operators make accurate determinations about whether they need to send out crews to fix a broken bike or dock as well as dealing with maintenance (维修) issues in a timely manner.
To be sure, algorithms can’t fix every new transportation problem and they have many limitations. But what is clear is that many challenges that come with new options, including e-bikes and free-floating bike-share systems, require the real-time data-driven approaches.

4 . My name is Pablo. I think I’m a lucky guy. I have a good family, and we live in a nice neighborhood in Puerto Vallarta, Mexico. People travel here from many countries for their vacations. We have beautiful beaches, hotels, restaurants, shopping and sports.
However, in my beautiful hometown, there are also very poor neighborhoods. These areas are crowded and have a lot of crime (犯罪). Life is terrible for many of the children in these areas. Some don’t really have a childhood because they’re homeless and live on the streets. They don’t have education. They don’t have enough food. Many use drugs or have illnesses or other problems.
Last year, I came back to Puerto Vallarta from my university in Mexico City, I spent one year as a volunteer with an organization called Outreach International. They have several programs. I volunteered for one program to help street children.
I worked in a home for street children (all boys, at this one). At this home, the boys have a place to sleep and three meals daily. The home keeps the boys off the streets. It shows them another way of life. As a volunteer, I helped to prepare meals. I taught games—such as basketball, football and art. I helped the kids with their homework. These kids can be fun. They have a lot of energy, but they’re also really tough (坚韧的). Their long and difficult time on the streets make them strong and not always “sweet little children”.
At this boys’ home, I met two other volunteers—Brian from Canada and Greg from Australia. In many ways, we were very similar. We were the same age, came from good homes and had a good education. They were both college students, like me. We became very good friends. Now, we email each other.
It was the best—and most difficult—year of my life. I learned a lot that year.

10 . Many families take their children on vacation. They will usually travel for a few days or weeks during school breaks. But Julie and Tim Smith have planned a longer vacation with their two children. The Smith family is on a one-year trip around the world .They plan to visit 30 countries in all. Right now, the four travelers are about halfway through their trip.
Ms. Smith says they are trying to see as much of their world as they can. Mr. Smith says one of the most interesting experiences of the trip has been meeting new people. He says people have been extremely friendly, very welcoming and love their kids. Eleven-year-old Tyler says he has enjoyed learning about the people they have met. He says, “I learned in Africa that people have very different lifestyles than in America."His sister, 9.year-old Kara, discovers that she likes Thai food. Ms. Smith says that the trip teaches the children a lot.
It took the family a year to prepare for the trip. They had to sell their house and cars. Ms. Smith left her job and her husband is using unpaid leave. They carry small bags filled with lightweight clothing and whatever else they need. Ms. Smith says she enjoys being able to carry everything she needs on her back. .She says she does not miss the things she has back home. “What has become more important is making these memories as a family and taking ”those” with us instead.”
The Smiths will continue to head east for the next six months.
