5 . The best way to get around London is the Underground, or what locals call “the Tube”. However, you also have other forms of transportation to choose from.

The charm of traveling by bus is that you can see the sights. Fares start at 1. 75 pounds for a single ride with an Oyster card (牡蛎卡). Buses don’t take cash, so it’s best to have a top-up Oyster card to pay for your trip. Many bus routes cover the entire city and run 24 hours a day.

London Overground consists of six main routes traveling among many parts of the city. Rail fares vary by the time of day and the number of zones crossed. Like the Underground, using an Oyster Card rather than a Travel card (or paper ticket)is considerably cheaper.

Keep in mind that a lit-up taxi sign means it’s available. Taxis are metered, and you have to pay according to the time of day and the distance. There’s always a minimum fee of 3. 20 pounds. You can pay with cash, and all taxis accept credit cards.

Think twice before hiring a car. Londoners drive on the left. In addition, traffic and parking are awful, and the cost of petrol (or gas)is high. Using hand-held cellphones while driving is illegal. The speed limit on highways is 70 miles per hour.

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.

9 . The Gurugram-based startup Rivigo was founded in 2014 by Deepak Garg. The central objective of the now billion-dollar company was to create a model where no truck driver would drive for more than 5-6 hours at a stretch and would reach home the same day.

Looking to build a company, Deepak realized that the rise of e-commerce had dramatically increased the demand for trucks, yet in India the industry was struggling with a shortage of drivers. How could this be in a country of over a billion people with a high unemployment rate— despite healthy wages for truck drivers?

To solve this puzzle, Deepak visited small villages where many truck drivers could be found. During his one-on-one conversations he discovered that since truck drivers are almost always on the road, they often develop bad habits such as heavy drinking. Partly because of this, few villagers wanted a son to become a truck driver or a daughter to marry one. What, then, was the solution? Could it be to bring the drivers back to their homes every night? That could work --- but how could he make it happen if a trucker’s trip took three or four days?

A relay service, Deepak realized, could solve the problem. Effectively, he built truck stops four hours apart along a selected route. A driver could go from point A to point B, drop his truck there and pick up another truck to drive from B back to A. Another driver in turn would pick up the truck from B and take it to point C, and so on. This not only brought drivers home each night, but created great value for logistics (物流) companies. A truck that was previously used for only 10 to 12 hours a day, allowing drivers time to sleep and eat, could now operate for more than 20 hours, cutting total delivery times by almost half.

To be sure, there’s a lot of technology behind the scene. But the founder strongly believes being humane (人道的) above anything else is the biggest factor that distinguishes him from the common crowd.
