Delivery drones, as the name suggests,     1     (use) to deliver goods. At the moment, delivery drones are mainly used for military action and disaster     2     (relieve), like the distribution of medicines during emergencies, especially to places that are hard     3     (reach) by other means of transport.     4     can be predicted that before long many people will be using drones to deliver daily supplies     5     food and drink. Some companies are also developing passenger drones,     6     carry people in crowded cities. Just enter a destination,     7     the drones will fly the passengers where they want to go. This could not only save time, but also     8     (great) decrease road traffic. We can assume that with     9     (improve) technology in passenger drones, we will be entering the age of personal flying vehicles. There are also many other exciting new ways to use this technology. Whatever     10     (happen), we’ll all be interacting with drones on a daily basis. There can be no denying that the technology will have a huge impact on everyday life.

Chinese new energy vehicle companies, including battery and car makers, are entering Germany with innovations,     1     German car expert said this Friday. Key battery manufacturers in China are now building battery cell factories with large investments in Germany, thus     2    (bring) technology to the country. “China is helping Germany to carry out climate-friendly strategies more     3    (rapid),” said Ferdinand Dudenhoeffer, director of CAR Center Automotive Research Duisburg.

Germany’s government is aiming     4    (have) 15 million pure electric cars on the road by 2030. In the meanwhile, carmakers like NIO or BYD will bring their products and service to Europe. On Friday at its European launch event in Berlin, NIO prepared three new models     5     customers in Germany, the Netherlands, Denmark and Sweden.

Earlier this week, German car rental company and mobility service provider Sixt made an announcement and     6    (reveal) its plans to order 100,000 electric vehicles from China’s: YD over the next six years. Up to now, Sixt     7    (order) several thousand pure electric vehicles from BYD. The first vehicles would be available to Europe, starting with Germany, France, the Netherlands and the United Kingdom, in the     8    (four) quarter of 2022, according to the company.

“It is good for the exchange between Germany and China, through     9     we cooperate with technology-driven Chinese new energy companies. It helps us learn how     10    (advance) Chinese technology is and it encourages further exchange,” Dudenhoeffer said.

The Grand Canal of China was first dug in 486 BC, and well developed through the late 6th to early 10th century. From the late 13th until 19th century, with the highest section built and the overall length     1    (shorten), the Canal was turned into a main passage between northern     2     southern China as well as the economic lifeline of the country. Consisting of the Sui and Tang Grand Canal, the Jing-Hang Grand Canal and the Zhedong Canal, the Canal     3    (stretch) over 2, 700 kilometers, crossing eight provincial-level administrative regions and     4    (link) five major water systems. The Grand Canal also connects with the Eurasian Silk Road to the west and extends the water trade route to the east.

The Grand Canal was     5     notable achievement of the ancient Chinese people. Its connection of the political and economic centers played a     6    (centre) role in the political unity, economic     7    (grow) and cultural prosperity of China, and contributed to the livelihood, exchanges and integration of the population along its route.

The Grand Canal     8    (announce) by the State Council as one of the seventh batch of Major Historical and Cultural Sites Protected at the National Level in March, 2013 and registered     9     the UNSECO World Heritage List in June, 2014. This large-scale, living cultural heritage spreads like a huge dragon across the vast territory of China,     10    (it) ripples shining golden scales (鳞片) in the new age.

Most people are very familiar with the traditional cars being driven by burning fuel. And many have heard of electric cars,     1     are kind to the environment, but few people know about Tesla.

Tesla is a world-famous brand of an electric car made by Tesla, Inc.,     2     (devote) to the design and production of high quality luxury electric cars. Now it has become     3     second name for the electric car.

Tesla electric cars are     4    (wide) considered as the safest, the most luxurious and fashionable cars. They are free of pollution; they are quick     5     (speed) up and quiet to travel in. Furthermore, they’re easy to drive and comfortable to sit in. Their     6     (big) advantage is that once charged, they can travel as far as 500 kilometers.

Like many other new energy car makers, Tesla also     7     (come) across many barriers(阻碍) in terms of technology in the beginning, but they didn’t give up. They overcome the     8     (difficulty) one by one and eventually produced the first Roadster(跑车) successfully in 2008.

2010 was no doubt a vital year     9     Tesla, in which the company was successfully registered on the NASDAQ stock exchange(纳斯达克股票交易市场). Today, Tesla electric cars     10     (sell) all over the world. Most of their owners are buyers who are rich and crazy about protecting the environment.

Both research and     1     (explore) in the Arctic are fundamental to understanding and dealing with climate change issues. With the melting of Arctic ice, the polar region could provide an opportunity to     2     (well) understand the effects of global warming. The Arctic is     3     great importance, among other things, for the environment, trade, investment, energy and security. It is evaluated     4     (have) a quarter of the world’s oil and natural gas. China has a clear Arctic policy, explained in a White Paper,    5     corresponds well with the concept of a “Polar Silk Road”.

Thanks to global warming, Arctic ice is melting,    6     (open) up the possibility of a “Northern shipping route” via the Northwest, Central and Northeast     7     (passage). Shipping time between China and Europe via the Arctic would be shorter than     8     existing one through the Indian Ocean and Suez Canal. Although this does not mean the “Northern route” would replace these established ones, it would represent a new chance,    9     (particular) in the trade of energy and minerals. As issued in the white paper, great importance     10     (attach)to voyage security in the Arctic shipping routes and studies on the routes by China these years.
