6 . Like all big cities, Paris has a traffic problem: lots of cars, lots of traffic jams and lots of pollution from exhaust fumes (废气). So the city began a scheme (计划) to improve the situation.

Under the Velib project ('Velib' comes from vélo liberté, or 'bicycle freedom') people can take a bicycle, use it for as long as they want, and then leave it at the same or another bicycle station. The first half-hour on the bike is free, but if you don't return it after 30 minutes, you have to pay. But it's only €1 a day or €29 a year! The bicycles are heavy (25 kg), and they are all grey and have baskets. There are about 20,000 of them in the city, and around 1,450 bicycle stations. So there are a lot more Velib stations than the 298 subway stations!

Paris is not the first city to have a project like this. But not everybody thinks it's a great idea. One Parisian said, "These bicycles are only for short journeys. If people want to travel across the city, they won't use a bicycle — they'll still use their cars."

A city spokesman said, 'The bicycle project won't solve all our traffic problems, of course. But it might help reduce air pollution. Traffic, together with factory fumes, is a big problem. There aren't any simple answers to traffic problems and pollution in cities. But unless we do something now, there will be more traffic jams and temperatures will continue to rise, so the problems in our environment will get worse. The bikes might help people to lead a healthier life, too.'

7 . Yangsigang Yangtze River Bridge, the double-deck suspension (悬浮) bridge with the longest span in the world, opened to traffic on Tuesday after five years’ construction, according to a statement from the constructor.

It is reported that the bridge is 4. 13 kilometers long, with 12 lanes in both directions on the main I bridge. It is a long-span suspension bridge with the largest volume in the world, China Railway Major Bridge Engineering Group said. The bridge connects the Hanyang and Wuchang and its opening will ameliorate the urban expressway system, relieve traffic pressure across the river, and drive development in the area, according to the company.

On both sides of the upper deck of the bridge, there is a two-meter-wide footpath, with eight rest and sightseeing areas, where people can enjoy the river scenery. The lower level is designed with two non-motorized lanes, each 2. 5 meters wide. A 1. 5-meter wide walkway is also a feature of each side of the floor so pedestrians (行人) can walk on the lower level without getting caught in the rain.

Chief designer of the bridge, Xu Gongyi, said, “Considering navigation and traffic volume, the main span of the bridge is 1, 700 meters, which is the second-largest in the world and also the largest in bridges of double-deck structure.”

According to Luo Ruihua, project manager of the bridge, the Yangsigang Yangtze River Bridge has set several records in the process of its construction. The designed tension of each of the two main cables (钢索) is 65, 000 tons.

From 2014 to 2019, builders have shown the world the speed of China. The bridge not only enhances Wuhan’s reputation as a “bridge museum”, but also represents a super project of a new era.

10 . You Can Fly More Frequently

When traveling, airfare can take up a large part of your travel budget. What if you could fly practically for free? If it were possible, then you would probably travel more, right?     1    . While it may seem like a lot of work to accumulate miles, it’s pretty easy when you know how.

Sign up for mileage (里程) programs. You can’t gain miles if you don’t sign up.    2    . Pick one or two airlines that you use most often and try to bring all your points into those programs by flying with them.

Buy gifts and have dinner out. Most mileage programs have a business list where you can register several credit or debit cards and then earn miles for each purchase you make through their participating shops or meal you have at restaurant partners.     3    , so why not make it count toward future travel?

Use your credit card. Look for a card that gives you rewards. There are a ton of credit card companies that offer mileage cards that give you miles for each dollar you spend. Use it for bills, groceries, gas and anything else you would normally use your bank account for and then pay it off at the end of the month.     4    .

Rent a car. Whenever you rent a car, you have the choice to include your frequent flyer member number.     5    , but it can be more beneficial to pay less than a dollar a day to earn one or more miles per dollar spent on your rental.
