Many drivers dream of the day 【小题1】 they can sit back while their car drives itself. 【小题2】 several companies are working hard to make it a reality, self-driving cars still face many problems.

Google was one of the first 【小题3】 (get) into this industry. It 【小题4】 (develop) self-driving cars since 2009, and its new driverless car is called Firely.

According to the MIT Technology Review, the current driverless cars can’t react like a human driver. They can’t drive in heavy rain or snow.

Chris Urmson, director of the Google car team, said that this is because the detection technology is not yet good enough to separate certain objects from weather conditions. In the cars’eyes, raindrops and snowflakes are the same 【小题6】 rocks, and cars stop for them. But if the manhole (下水道入口) ahead is uncovered, they drive over it without hesitation.

But even at that time, driverless cars won’t be truly “driverless”.

In the US, only 【小题8】 someone sits in the driver’s seat are driverless cars allowed on roads in certain states.

European countries, Mexico, Chile, Brazil and Russian follow the United Nations Convention on Road Traffic. The convention used to say: “Every driver 【小题9】 at all times be able to control his vehicle.” A change was agreed in May, 【小题10】 (allow) a car to drive itself as long as a driver is in the car and able to take the wheel at any time.

Trains are cleaner, greener, more spacious and 【小题1】 (general) less troublesome than planes. Once 【小题2】(view) as travel’s past, rail is now starting to look a lot like the future. In the USA, a huge expansion of the train network is drawing 【小题3】 (people) attention. And in Europe, some very cool plans have been made for a whole new generation of sleeper trains.

Sleeper services, 【小题4】 operate overnight between major destinations, get rid of the main disadvantage of train travel: the lengthy journey time. Like a red-eye flight on rail, you can board the train in the centre of one city and wake up in 【小题5】, ready to drink a cup of coffee and explore.

Once numerous, Europe’s night trains have been cut back gradually over recent decades. But that trend is reversing (逆转).We’re very excited to hear about the 【小题6】 (announce) of five new European night train routes, launching over the next four years. A total of eight European countries 【小题7】 (link) by the new routes.

【小题8】 short, your European travels over the 【小题9】 (come) years are going to involve hanging around not at airports 【小题10】 through railway stations. Needless to say, we’re into it. All aboard!

With the【小题1】(adopt) of e-ticket service on the high-speed line【小题2】(link) Lanzhou of Gansu province and Urumqi of the Xinjiang Uygur autonomous region on Wednesday, all 1,075 high-speed and intercity railway stations on the Chinese mainland will allow passengers to check in【小题3】a paper ticket. The move will streamline boarding procedures and improve services.

【小题4】entering the station and checking in, passengers only need【小题5】(scan) an identification card at the self-service counters. Those【小题6】ID cannot be read by the machines will be able to check in through the manual channel.

The service【小题7】(introduce) on the island-looping high-speed rail line of Hainan province in November 2018. It was then promoted to the majority of the high-speed railway stations across the country during the【小题8】(four) quarter last year.

After going through tests of the robust traffic during the Spring Festival, summer vacation and other holidays, the e-ticket system has been operating【小题9】(safe) and steadily while getting positive passenger feedback.

The system has also grouped【小题10】disabled, people with children, students and the military in online accessibility to discounted tickets.
