    About sixty years ago, China was known as the "Bicycle Kingdom". But the two-wheeled way of transportation began to become less popular, with many bikes soon replaced by their four-wheeled competitors.

    But recent months have seen a revival(复兴) of the bike across China, with an increasing number of people choosing cycling instead of driving to schools, to workplaces or to do sightseeing. The introduction of bike-sharing plans, pioneered by companies like Ofo and Mobike, has brought cycling to a new level. According to the latest data, the first week of this year saw 5, 850,000 active users of Mobike while Ofo had 1,400,000 active users.

    People can unlock the shared bikes by simply using their smartphones. The bikes are equipped with GPS and can be left anywhere in public for the next user. They are popular among many Chinese people. "In places where the underground railway doesn't extend, it's so easy to get where you want to go with Mobike," Hu Hong said. She cycles to her workplace in Shanghai.

    Bike-sharing is a greener method of transportation and provides a user-friendly experience. However, the plans have also led to problems such as illegal parking, breaking and stealing. Last month, two nurses in Beijing put locks on two shared bikes. And in December, a man stole a shared bike.

    Now Chinese service operators are also trying to solve these problems. Setting credit points is one of the ways. Mobike sets a 100-point credit score for each user, with points taken because of bad behavior. Once a score drops below 80, bike Tental((租金) is increased to 100 yuan per 30 minutes rather than 0.5-1 yuan.

Have you ever been to Thailand?

    Now we are staying in Bangkok (曼谷) It is the capital of Thailand and it is a very interesting place to visit. Yesterday we visited some places of interest in the city. They are great! This morning we went shopping.

When we eat in the restaurants in Bangkok, the waiters are really nice and they are always smiling. Thai food is delicious, but it is sometimes a little spicy (辛辣的) for me. You can also get Chinese food here because a lot of Chinese people came to live in Bangkok many years ago. American food can also be found in Bangkok, however, I don't eat it. I'd like to try new things when I travel.

    Yesterday it rained and got a little cooler. But today it's hot again.

C. Thailand is called" Land of Smiles" because people here are very friendly.

D. It is a country in Asia.

E. Bangkok is a wonderful place to shop for jewelry (珠宝) and clothes.

These _______ some stamps from Canada.

Despite earning more than $ 100,000 in household income, many people feel that they are living month to month and that a loss of employment or sudden medical emergency could easily move them from the upper middle class to low income earners. This feeling of being on the "edge" of poverty, despite these levels of income, seems a bit ridiculous but it really comes down to easy credit, misunderstanding of their incomes and peer group pressures.

Even in today's tough economy, for those with six-figure incomes credit is easy to come by. Credit companies may have cut back offerings to those in lower income brackets due to the recent credit reforms, but there seems to be little or no effect on high income earners. Their being able to get credit without difficulty gives them a false sense of security that makes them spend way more than their incomes can afford. That's why they accumulate credit card debt faster than average.

Many higher income earners feel like they are making lots of money now, and believe that they will continue to make big money. This may reduce their feeling that they need to watch their money carefully now. Hand in hand with that, many of them probably believe that they are making more money than they really are — or said another way, the money they make will go farther than it really does.

Meanwhile, many young professionals who are earning good incomes don't come from particularly privileged backgrounds, and their reference point may be that they are making twice (or more) than their parents were — so they spend like that as well. They don't take account of the effect of inflation, which means that the cost of living is much higher than that in their parents' generation. Further, the more you earn, the more you pay in tax. Rather than focusing on after-tax incomes, many high income earners only look at the top line figures. A $ 100,000 income before tax is only about $ 70,000 after tax.
