Beijing, together with Zhangjiakou, succeeded in getting the chance to host the 2022 Winter Olympic Games,     1     speeds up the development of Zhangjiakou City. Word came that the Beijing- Zhangjiakou high-speed railway,     2     (locate) in North China, is now     3     construction, and is expected to be completed by 2020 in preparation for the cities to host the 2022 Winter Olympic Games.

Starting from Beijing North Railway Station and heading west through the Great Wall, the project is     4     (probable) the biggest challenge ever. Its designers say that the explosions needed to dig the tunnels will not have     5     negative effect on the structure.

The railway line has a     6     (long) of 174 km as a double-track passage line, with ten stations along its route. Enjoying a total investment of 31.17 billion yuan, the train will travel at an average of 250 km/h，     7     the trip between the two cities will only take 40 minutes.

According to the plan, the high-speed railway will have two branch     8     (line) —   one is to Yanqing Station, the other is to Taizicheng of Chongli, where the Olyimpic village lies. The full railway,     9     (include) a 70-kilometer section through Beijing,     10     (complete) in four and a half years.

Let’s ride bicycles

Good morning, everyone! I’m Jack from Honor Senior high school. The topic of my speech is “Let’s ride bicycle”.

As is known to all, with the     1    (improve) of people’s living standards, cars have become a popular means of transport,     2    (bring) great convenience to our life.     3    , they have also caused some problems such as air     4    (pollute) and traffic jams.

How can we solve the problems then? As far as I am concerned, riding bicycles is a good solution. For    5     thing, bicycles don’t need     6    (some) petrol and they are energy-saving. For another, bicycles are environmentally     7    (friend) because they won’t give off waste gas. What’s more, riding bicycles is a good way for us     8    (exercise) and it is beneficial to our health.

Therefore, let’s take the responsibility to build up a low-carbon city by     9    (ride) bicycles. Come on and     10    us !

Thank you!

The Hong Kong -Zhuhai-Macao Bridge (HZMB) , the    1    (eight) wonder of the 21st century, opened    2    the morning of October 24th, 2018. The bridge links three areas, making    3    much more convenient to travel from one to another. Since opening, the three-hour drive between Hong Kong, Zhuhai and Macao    4    (shorten) to 30 minutes.

The project involved more than 400 new patents, broke seven world records, and featured    5    (independent) developed key techniques and design. After an 8-year struggle, the success of the HZMB achieves    6    several generations have been dreaming of, and amazes the whole world with its demonstration of perfect skills and high-level Chinese standards. The bridge is intended to be    7    (rely) for more than 120 years. From the Belt and Road Initiative to "Created in China", there is always a group of people    8    (provide) strong technical support for each of the country's huge projects. From the beginning in December 2009 to the day of the official opening, all    9    (walk) of life made great contributions    10    the design and construction of the HZMB, contributing "Wisdom of China".

Last December my mother and I     1    (fly) to London. The first thing we did was to go on a bus sightseeing tour.

This is the best way to see all the sights and learn all about the history of a city. By the time the tour was over it was dark. The Christmas lights were very colorful. And     2     really impressed me was how so many people made     3    (they) way home through the heavy traffic on bicycles. I was looking forward to spending the next day in Oxford Street with all its     4    (amaze) shops. And what     5     experience that was! We bought a ticket for the underground and could go everywhere very quickly.

We spent all morning shopping and admiring the Christmas displays inside the shops and out in the streets. Then we went to a wax museum     6    (call) Madame Tussauds (杜莎夫人蜡像馆), which had a lot of wax     7    (figure) of famous people. My mother took a picture of me     8    (stand) between Prince Charles and Prince Harry. From there we took a taxi to Buckingham Palace, the home of the two princes, to watch The Changing of the Guard but     9    (fortunate) we couldn’t really see well as there were thousands of tourists waiting     10    (take) photos of the ceremony.

Your next car could have two seats, three wheels — two in front and one in the back and a top speed of more than 100 miles per hour. Elio Motors plans to make such a tiny car     1     (name) the Elio. Its two seats sit front and back instead of side     2     side. The driver is positioned in the center with the passenger directly behind.

The starting price for the car is just $6,800. It has only one door, on the left side,     3     cuts a few hundred dollars off the manufacturing costs. Having three wheels also makes it     4     (cheap). It has air conditioning, power windows and door locks and     5     AM/FM radio. More equipment can     6     (order) through Elio's long list of suppliers. Elio will also sell the cars directly through its own stores and not through franchised dealers (特约经销商).

Paul Elio dreamed as a kid that he     7     (own) a car company called Elio Motors. In 2008, tired of high gas prices, he started working on a car that burns gas in a more effective way.     8     (equal) important to him was creating U.S. manufacturing jobs and making the car inexpensive enough     9     (attract) buyers who might otherwise be stuck in their old, unreliable cars. “Whatever matters to you, this can make a     10     (different) to it,” he said.

Texting while crossing the street will soon     1    (ban) in Honolulu, Hawaii. From October 24     2    , you could be fined if you step into a Honolulu street while looking at your phone. Honolulu is the first major US. city that passed a law,     3     says, “No pedestrian shall cross a street or highway while viewing a mobile electronic device.”

The law     4    (include) all electronic devices with screens, cell phones, tablets, gaming devices, digital cameras and laptop computers. The law does permit     5     exception. Pedestrians may use such devices in the street to call emergency services and rescue workers, such as firefighters and police     6    (office).

    7    (hope), it will lower the number of people hit and     8    (kill) by cars in the city. Pedestrian deaths in America have been increasing as the use of cell phone rises. Honolulu has     9    (many) pedestrians hit in crosswalks than almost any other city in America. The number of pedestrian deaths in 2017     10    (rise) to 6,000, 11% higher than in 2016.

As the countdown to the 2022 Beijing Winter Olympics continues, the new high-speed railway line     1     (connect) the capital with Olympic host city Zhangjiakou has just entered service. It cuts the travel time between the two from three hours     2     47 minutes. The route will stop at 10 stations, Badaling Chang Cheng station     3     (include). But this isn't just another bullet train(动车). This beauty, part of China's Fuxing series, can run up to 350 kilometers per hour without a driver--said to be the world's first smart high-speed railway.

So what makes them “smart”? Well, the carriages(车厢)     4     (equip) with5G signals, intelligent lighting and sensors to collect real-time data and detect any operational abnormalities. Meanwhile, each individual seat has     5     (it) own touch-screen control panel and wireless charging docks. Though the high-speed trains on the route are autonomous(自主的),     6     monitoring driver will be on board at all times. The trains can automatically start, stop and adjust to the different speed     7     (limit) between stations. Back at the station, robots and facial     8     (recognize) technologies can help passengers with directions, luggage and paperless check-ins.

Today, China is home to the world's largest high-speed rail network, and the     9     (fast) commercially operating train—the Shanghai maglev. According to the China State Railway Group, 1,036 Fuxing bullet trains have been put into operation since 2017.     10     the series first launched.
