1 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

Monorails (单轨列车) have been around for more than a century and examples can be found all over the world,     1     they’ve never quite fulfilled the futuristic promises of their early promoters. That said, there are a few places where the unique     2     (quality) offered by monorails are ideally suited to their environment.

Chongqing, a megacity which     3     (locate) in southwestern China, is home to the world’s longest and one of its busiest monorail system, carrying millions of passengers a year on two high-capacity “straddle beam” lines     4     (total) 61 miles in length. At just over 34 miles, Line 3 is also the world's longest single monorail line     5     an annual ridership of around 250 million.     6     (put) into operation between 2005 and 2016, the two lines have 70 stations with a mix of underground and elevated sections.     7     (famous), one section of Line 2 passes through the heart of a high-rise apartment block.

Back in the 1990s, the city’s unique geography, with extreme differences in altitude between its densely populated mountain plateaus and the Yangtze and Jialing river valleys,     8     (force) Chongqing’s transport authorities to seek     9     alternative to conventional subway trains. Monorail’s capacity     10     (negotiate) steep climbs and tight curves made it the ideal solution when this megacity needed to transform its public transport system.

2 . 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.
