It's common       1     (see) food delivery workers on electric bikes through crowded cities in China. Most of them are in     2     hurry. However, such reckless(鲁莽的) behaviors often cause serious problems.

One deliveryman surnamed Li     3    (interview) the other day. He's been only doing this job for 2 weeks but has already ridden in wrong lanes a few times just to be punctual. In the     4     (one) half of last year, food deliverymen had 76 traffic accidents in Shanghai alone,     5     means on average, a food deliveryman got hurt or died every 2.5 days.

The phenomenon is       6    (close) related to the growing demand for delivery services, reported People's Daily. About 10% of Chinese are turning to food delivery services, according to China Radio International. Such a huge market     7    (lead) to booming delivery growth by now, with companies offering high salaries to attract new staff.

However, food de liverymen are often under high pressure, faced with fines of ¥20 for being late and up to ¥200 for receiving complaints. Also, the more orders, the higher earnings. Thus,     8    (safe) pops up as a big concern.

Solution? Yes. Shanghai has laid stress on traffic rules. Now in Shenzhen, if caught     9    (break) traffic rules twice, the deliveryman is banned     10     driving vehicles for a whole year!

Car registration plates (牌照) are just a series of numbers and letters, right? Well, yes…but not for everyone.

France was the first country     1    (introduce) plates in 1893. Early number plates differed     2    shape and size, and were made of lots of different materials, including iron, cardboard and even pressed soybeans. In fact, it was not until 1957     3    car manufacturers and the governments agreed on standardized(标准化) plates.     4    was first registered in the UK was A1. The letter “A” showed the number was from London, while the number “1” showed it was the first number issued. At the moment, number plates     5     (consist) of a sequence of letters and numbers are applied in the UK.

Different EU countries also use different arrangements of numbers and letters, and     6     systems have changed many times because these letter-number     7     (combine) keep running out. In the past decades, some number plates     8     (become) extremely valuable, particularly those that spell out words.     9     (basic), numbers on the plates can be used to represent words or parts of words. For example, “NVERLA8” means “Never Late”. And the most     10     (expense) number ever was “M1” which an anonymous(匿名的) buyer has acquired for ￡331,000.

People have long dreamt of a car that flies through the sky. Japan′s SkyDrive has carried out a successful, but modest test flight of such a vehicle carrying a person. In a video     1     (show) to reporters last week, a vehicle that looked like a motorcycle with propellers (螺旋桨) lifted up to two meters off the ground. It     2     (fly) in circles in a protected area for four minutes. Tomohiro Fukuzawa heads     3     SkyDrive effort. He hopes the flying car can     4     (make) into a real-life product by 2023. Of the world′s more than 100 flying car projects, only a handful has succeeded with a person     5     board.

The machine so far can fly for just five to 10 minutes,     6     if the flight time can be extended to 30 minutes, the car will have more possibilities. Unlike airplanes and helicopters, “electric vertical takeoff and landing vehicles”, generally offer quick point-to-point personal travel. They could do away with     7     (have) to deal with airports, traffic jams and the cost of paying for pilots. Such vehicles could even fly without a pilot.

The Japanese government has expressed support for the futuristic project. The goal is to expand the flying car′s     8     (commerce) use by the 2030s. It also has noted possible uses for connecting faraway     9     (region) and providing transportation in disasters.

Experts compare the excitement about flying cars to the days     10     the aviation industry got started with the Wright Brothers and the auto industry with the Ford Model T.

I’m Richard,     1     exchange student from the UK. During the October holiday, my parents and I went to Xi’an     2     (see) the Terrocotta Army. The story of the Terrocotta Army is     3     (extreme) unbelievable. It’s     4     (amaze) that there are more than 8,000 statues, and no one     5     modern times knew about them until the 1970s.We also visited the Shaanxi History Museum, which     6     (know) as a “Chinese Treasure House.” Of course, the Xi’an City Wall and a few other famous sights also left us a deep     7     (impress).Though tired, we enjoyed     8     (us) during the trip. The trip is so wonderful     9     we’re looking forward to     10     (explore) other big cities in China.

Bike sharing is a new choice for short journeys in cities. It is good     1     the healthy development of big cities.     2     report by a company found that shared bikes started the nation’s love for bikes again. Now more and more Chinese people     3     (choose) bikes instead of cars to make short journeys in cities.

Since the start of shared bikes, people have made     4     (few) trips by car. The love for shared bikes is not only among young people,     5     were born in the 1980s and 1990s, but also among the old people who are over 60. The shared bikes like Mobike and ofo are useful to people. You can use them by     6     (simple) using your smart phone. People can ride these shared bikes to some places where the subways and the buses don’t go.

However, bad things happen. Some people damage the QR code(二维码) on the bike, or use their own lock, which causes trouble to other users. As for the situation, it’s difficult     7     (correct) these people’s behaviors in a short time. Therefore, bike-sharing companies need to do something. For example, people can     8     (ask) to register as a user with     9     (they) real names. It’s a good way to connect to one’s personal credit. People who damage the bikes should pay for their     10    (act).

In Europe, most capital cities     1    （plan)and built before cars,and city centre traffic jams     2    （be)part of daily life for a long time.The situation in central London,     3    drivers spent fifty percent of their time in queues,became so bad     4     the local government decided to do something about it.In February 2003 the mayor of London introduced a"congestion charge"-a tax for cars     5    （enter)the centre of the city.

I stood on the deck,     1    ( stare) at the huge waves. From the moment we had left port and sailed into the English Channel,     2     weather had got worse and worse. Now, lightning flashed across the sky ,     3    was covered in dark clouds.

Suddenly, the noise of the engines stopped. The ship slowed, rolling heavily in the rough sea. A voice over the loudspeaker told us     4    (remain) calm — then added that a fire     5    (start) in the engine room, and said that all passengers must go     6    (immediate) to the nearest lifeboat station.

We all ran onto the deck, following the signs to the lifeboats. The ship’s officers arrived, made sure we had life jackets and showed us     7     to put them on.

I looked again in horror at the wild, stormy sea. The     8    (think) of being out there in a tiny boat was     9     (terrify). Minutes passed like hours, until at last a voice announced that everything was     10     control and the danger was over.We all cheered as the engines started again and the ship moved forward into the waves.

I still couldn’t believe it was over, though — not until we had reached port and I was standing on solid ground again!

The London Underground is the oldest underground network in the world. It normally     1    (operate) between 5 am and midnight. Some lines stay open throughout the night on special     2    (occasion), like New Year’s Eve. The London Underground stations can get very     3    (crowd) during the weekday rush hours. Over the decades the London Underground stations have been modernized. In the past few years, many     4    (equip) with Wi-Fi access to make passengers’ journeys as comfortable as possible.     5     well-known symbol of the London Underground, a red circle with a blue bar, was created at the     6    (begin) of the 20th century and has not changed much since then. Some of the London Underground stations are buildings     7     have special architectural values. Many original stations have been restored     8     they look similar to the way they did over a century ago.

With so many people     9    (use) it every day, the London Underground faces environmental problems. Because the water level of the Thames is on the rise     10    (constant), thousands of cubic meters of water must be pumped out of the underground stations every day.
