1 . School buses are familiar to most people. However, Sam Balto, an elementary school teacher, creates a brand-new ______ of school buses in Portland, Oreg. ______ loading kids into the yellow vehicles, he involves them in a school “bike bus”. The bike bus ______ differently from the way school buses do. There’re two meetup locations for kids. After the two groups ______, the children cycle to school together.

Though popular in some areas, bike buses are still ______ in the U.S. Balto’s idea for that began as an initiative for Earth Day, which surprisingly became a ______, with most students in Balto’s school participating. Then he decided to ______ . Now ______ the bike bus in action. “Kids ______ the ride. Parents notice on bike bus mornings, kids get up and out of home ______. They’ re eager to be with friends,” said Balto. Actually, its ______    go beyond promoting socializing. The physical activity helps ______ kids’ strength and it’s also climate action.

Right now, Balto feels it’s ______ to offer the bike bus once a week and he’s relying on volunteers and seeking official ______. “It can be a daily way to transport kids if cities or schools pay adults to lead it,” Balto explained. If possible, he encourages other Portland schools to ______ them. “More kids across the city should have such pleasant experiences.”

2 . On the eve of this week’s rail strikes, it was reported that the industry bosses are planning to weed out paper train tickets and close almost 1,000 station ticket offices in England. The transport secretary, Grant Shapps, has made no secret of his desire to see costs saved in this way. Some stations sell only a handful of tickets each week and the vast majority of transactions (交易) have moved online.

In the name of cost-cutting, station ticket offices are likely to follow the telephone booth on the comer and become memory. For those who have grown used to the benefits of organizing travel via smartphones, there will be little to feel sorry for. But for people without online access or skills ― who tend to be older, poorer, and more fragile-another social barrier will have been built.

From medical appointments to payment apps for parking, more and more key services are now delivered digitally. As this revolution takes place, the interests of a significant minority are being ignored to some extent. In the case of health and social care, for example, it will often be those most in need of assistance who are least able to employ electronic devices.

The debate over ticket offices offers an opportunity to reflect more broadly on the increasing role of technology in our social landscape. The unavoidable trend towards technology is predictable, but its possible consequences need to be managed with more care. With the expanding range and increasing complexity of digital requirements, the aged are gradually withdrawing from increasing social services in their lives. Ros Altmann, the former pensions minister, recently wrote of being contacted by an elderly woman who no longer drives to her local park, because she cannot download the car parking app required.

Much more needs to be invested in helping gain easy online access. Alternative offline options must be maintained for important services. Contactable telephone numbers of relevant staff should always be available. These will cost more. But that is the price of digital transformation.

Bullet trains tailored (量身定做) for the high-speed railway network linking the Indonesian cities of Jakarta and Bandung are unveiled (公开) in Eastern China, marking an important milestone of the project     1     preparing for the line’s scheduled opening, China Railway International says.

A total of 11 sets of bullet trains and an inspection train, all adopting Chinese standards, are showcased in Qingdao, Shandong Province. They     2     (ship) to Indonesia soon.

According to China Railway International, a subsidiary (子公司) of China State Railway Group,     3     is overseeing the project, the trains, designed and developed by CRRC Qingdao Sifang Co, Ltd, are based on     4     (advance) and mature technologies of China-made Fuxing bullet trains which operate at the speed of 350 km per hour. The CRRC has also made    5     (change) to adapt to the local environment and routes, as well as incorporating (融入) Indonesia’s cultural elements     6     (give) passengers more comfortable traveling experience.

The 243-kilometer-line,     7     landmark project of the China-proposed Belt and Road Initiative,     8     (begin) construction in 2018 and is expected to open to traffic in June, 2023.

With trains capable of     9     (reach) speeds of up to 350 km per hour, the line will cut the journey between Jakarta and the capital of Indonesia’s West Java Province from over three hours     10     just 40 minutes.

4 . This week, Parisians have been treated to the sight of ecotaxis, transporting people up and down the river Seine. They are called SeaBubbles and are being tested ahead of the decision to introduce them into the Parisian transport network. The SeaBubble is still in its early testing period, using technological know-how from several industries. The boat sits in the water as the passengers get on and off but once the door is closed the boat starts moving at 12 kmh (7.5 mph) along the surface. It is 100% electric.

The foils(箔) they use are not new technology. They date back to 1898 and an Italian engineer called Enrico Forlanini. The Germans tested foil boats in the 1940s, the first hydrofoil ferry(水翼渡船) was used between Switzerland and Italy in the 1950s and by 1965, a hydrofoil boat was good enough for the James Bond baddie in Thunderball. What has changed, however, is the technology, which has improved to the point where it can now succeed in dealing with some of the shortcomings which prevented their widespread use.

The company has big goals; it wants to use the world’s waterways—and not roads—to transport people from A to B, and it wants to do so with “zero wave, zero emission(排放), zero noise.” The SeaBubbles would travel at the same speed as cars and the goal is to provide these at the same cost as a taxi, with customers ordering them through an app as they would an Uber.

Anders Bringdal, SeaBubbles CEO, told Associated Press that he hopes to change the way people move about cities. SeaBubbles are one more example of how shared public transport can change the mobility of large cities, much like shared bikes are now doing. People are increasingly looking to rivers as a means of moving around large cities to compete with the subway or buses—in London, travel cards are now accepted on river boats.
