A travel insider has warned Brits planning holidays that flight ticket prices are due     1     (soar) over the coming months. With inflation (通货膨胀) soaring     2     more than 10% and many households struggling to keep up with rocketing gas bills, the latest news will be a     3     (particular) unwelcome one for British people desperate to get away this year.

Willie Walsh, director general of the International Air Transport Association, has said that rising oil prices in part     4     (cause) by the war in Ukraine would lead ticket costs to jump up. “Oil is the single     5     (big) element of an airlines’ cost base and ultimately the high oil prices     6     (pass) through to consumers.”

Mr. Walsh also warned that flight cancellations would push up demand for     7     (seat) on other planes, inflating prices British Airways has grounded tens of thousands of services until the end of October, meaning     8     (it) typical summer schedule has been reduced by 18% in total. At the same time difficulty filling vacancies in hotels, bars and restaurants in the UK, along with sharply rising prices,     9     (mean) staycations are more expensive than ever.

The warning of rising plane ticket prices will make the prospect of going away     10     difficult one for families weighing up whether to stay in the UK or go abroad this summer.

Not satisfied with pushing the boundaries of speed, endurance and civil engineering, Chinese companies are among the first in the world     1     (introduce) new technology such as driverless train operation and advanced signaling and control technology.

The driverless bullet trains     2     (connect) Beijing and Zhangjiakou in northern Hebei Province are capable of hitting speeds up to 350 kph, which makes them the world’s     3     (fast) driverless trains. The new route, opened in December 2019 as part of preparations     4     the Beijing 2022 Winter Olympic and Paralympic Games,     5     (reduce) travel time for the 174-kilometer journey from three hours to less than 60 minutes so far.

    6     (build) in just four years, the line has 10 stations serving two of the major Winter Games venues (举办地), plus another at Badaling Changcheng, making the Great Wall of China faster     7     (access) for tourists.     8     latter is the world’s deepest high-speed railway   station, situated 102 meters underground. These stations are like airport     9     (terminal), with acres of spotless polished marble and glass, enormous information screens and lounges     10     passengers are held until their train is called.

At the end of the 19th century, nearly 40 percent of American cars were electric. In cities with early electric systems, battery-powered cars were     1     popular and reliable choice, compared with their gas-powered competitors.     2     early car batteries were expensive and inefficient. At the same time, new     3     (discover) of oil fields lowered the price of gas, and new advances made gas-powered cars more appealing. That's why gas-powered cars     4     (rule) the roads for the next 55 years. Aside from some special-purpose vehicles, electric cars were nowhere to be found.

However, in the 1980s, the tide began to turn. Studies associating car emissions     5     smog(霾) encouraged governments to reconsider electric vehicles. Many companies were developing increasingly efficient batteries at that time. In 2008, Tesla Motors went further,    6     (attract) the attention of the world with its lithium-ion-powered (锂电的) sport cars,     7     could travel more than 320kms on a single charge. Since then, electric vehicles     8     (improve) in cost, performance, efficiency and availability. They can accelerate     9     (fast) than gas powered sports cars. And though some models still have a high upfront cost, they save their drivers money in the long run.

As governments around the world focus on slowing climate change, electric vehicles are now expected     10     (replace) gas-powered ones altogether. Soon, electric cars will reclaim their place on the road.
