Private cars used to be a luxury for most Chinese people， while today they can be seen everywhere in China as an indispensable part of life。 Not only do people drive to and from work， but they often travel by car。 In some cities， the growth of cars is so fast that the problems of traffic jams and lack of parking space become more severe。 The municipal governments of these cities therefore have to introduce new rules to limit the number of cars on the road。 Also， the increasingly serious air pollution has driven more consumers to choose new energy vehicles， so the Chinese government has taken some measures to support the development of new energy vehicles。 （117）

China currently has the world’s largest and fastest high-speed railway network。 The speed of high-speed trains will continue to increase， and more cities will build high-speed railway stations。 High-speed rail greatly reduces travel time。 Compared with aircraft， high-speed trains boast the outstanding advantage of punctuality， because they are hardly affected by weather or traffic control。 The high-speed train has greatly changed Chinese people’s way of life。 Today， it has become the preferred means of transport for many people on business trips。 Also， a growing number of people travel by high-speed trains during holidays。 Many young people even choose to work in a city and live in a nearby city， commuting by them。 （112）

Bicycles were once the most important means of transport in China‘s urban and rural areas， which made China “the kingdom of bike。” Nowadays， as urban traffic congestion and air pollution become more serious， cycling has gained popularity again。 Recently， Chinese entrepreneurs， combining mobile Internet technology with traditional bicycles， invented a business model called shared bicycles。 The advent of shared bicycles makes cycling more convenient， for a shared bicycle can be used anytime with one mobile phone alone。 In order to encourage people to travel by bike， many cities have built bicycle lanes。 Now， more Chinese people also like to exercise by cycling。 （102）

For years, bike-sharing schemes have been common in big cities around the world, including in China. Examples include Paris’s Vélib and London’s Santander Cycles(Boris bike）.But these require customers to return the bicycles todocking stations.In China, a moreuser-friendlyapproach is spreading rapidly. It involves bikes that can be paid for using a smartphone and left anywhere. GPS tracking enables them to be located with a mobile app. A ride typically costs only one yuan ($0.15) on asleek-framedbike in an eye-catching colour.

The first such service was launched in June 2015 by a startup called Ofo. The company now has around 2.5m yellow-framed bikes in more than 50 cities in China. Its main rival, Mobike, which started up only a year ago, says it has“several million”of its orange-wheeled bikes spread across a similar area. Bluegogo has half a million bikes in six Chinese cities. It plans to add a new city every two weeks.

The dockless system is prone to abuse. Some riders hide the bikes in or near their homes to prevent others from using them. Another trick involves photographing a bike’s QR code and then scratching it off to stop others from scanning it. With the stored image, the rider can then monopolise the machine. But customers caught misbehaving can have points deducted from their accounts, making it more expensive for them to rent the bikes.

A bigger problem for the new firms is persuading people to use bikes instead of cars. Thirty years ago, 63% of Beijingers pedalled to work. Now only 12% do. Many people think that cycling is only for the poor. A dating-show contestant famously quipped in 2010 that she would“rather cry in a BMW than smile on a bike.”
④The emergence of shared bikes makes cycling more convenient。 People are able to use shared bikes at any time with only a mobile phone。

Cycling is also dangerous. About 40% of road accidents involve bicycles, according to a report in 2013. (Many bike lanes have been eliminated to make room for cars.) Some city authorities accuse the bike-sharing firms of causing congestion. This month the southern city of Shenzhen ordered limits on the number of shared bikes. Other cities, including Shanghai and Beijing, are considering similar measures.

But Chinese leaders like the services—they represent the kind of green innovation that China says it wants. In January the prime minister, Li Keqiang, told Mobike’s co-founder that her business model was“a revolution”. Not, presumably, the kind that Mao led, but one that would have made the chairman feel at home with its profusion of two-wheelers.

I’m writing to tell you more about the new form ofsharing bike mobike mentioned in your latest letter.
It’s veryconvenientto use if you have a smartphone. What you do is find a nearest mobikethroughthe APP, scan the QR code on the bike, and enjoy your trip.
Compared toother forms of sharing bike, the greatest advantage of mobike is that you can easily find one and never worry about where to park it. It is becoming a new trendas a means of transportation, which relieves the traffic pressureand does good to the environment as well.
Hope to ride a mobike with you in China.
最近很多大城市都投放了共享单车(shared bikes)，比如摩拜单车(Mobike)、Ofo共享单车等。由于它们方便停放，骑车也能起到锻炼身体的作用，作为代步工具很受大家欢迎。但是，各地也出现了很多毁车现象，比如刮掉车上的二维码(QR code)、上私锁等。

The shared bikes like Mobike and Ofobring great convenience to people. You needn’t lock them by simply using your smart phone. They can take you where the subway and bus don’t go. And they can be left anywhere in public for the next user.
However, bad things happen. Some people damage the QR code on the bike, or use their own lock, which causes trouble toother users.
In my opinion, it’s difficult to turn these people’s ideas in a short time. Therefore, bike-sharing companies like Mobike and Ofo need to do something. For example, those who damage the bike should pay for their actions. Also, because people use their real name to registeras a user, it’s a good way to connect to one’s personal credit.
In the end, what I want to say is to take good care of public services.
With the development of technology, bicycle sharing comes into people's lives. It becomes more and more popular and much news reported it. At the same time, we should see that there are some problems caused bybicycle sharing.
On one side, bicycle sharing makes it very convenient of people traveling. You can find a bicycle anywhere at any time when you want to go out for a cycling, and the price of one trip is very low. It cansave time forpeople. On the other side, its management is not perfect. Even kids can open the lock and ride the bicycle, there is no doubt thatsuch behavior is very dangerous. What's more, many people deliberately break it, like throw it to the river or destroy the code above it.
In my opinion, we should take a developing view about bicycle sharing. It is obviouslyhelpful to human beings as a high-tech product. The government should introduce relevant provisionstoregulatethis market to avoid its disadvantages.

My Views on Bicycle-sharing
Presently, in big cities like Shanghai and Guangzhou, bicycle-sharing system has becomeincreasinglypopular. A large number of shared bikes can be found and rented at a low price.Moreover, you can park the bike almost anywhere you like. Urban transportationhas thus been made much more convenient and even revolutionized.
However, along withits rapid development, bicycle-sharing system also brings some problems, including random parking, vandalism and possession of shared bikes, etc.
To solve these problems, there are some measures forthe authorities to take. Firstly, the government could implement more strict laws and rules to regulatethe operation and management of bicycle-sharing system. Secondly, the public should raise their awarenessof using shared bike reasonably. Lastly, urban transportation system should be upgraded and improved to accommodate automobiles, bikes and pedestrians.
To conclude, a sensible attitude should be held toward bicycle-sharing program. With effectiveand efficientmeasures taken, and efforts made by those involved, it can be expected that bicycle-sharing system will play a contributiveand constructive role in urban public transportation.
