The belt and road initiative is a significant development strategy proposed by Chinese  president xi in2013 September and October.

It aims to connect Asia, Europe and Africa with intention of promoting economic cooperation among countries along the proposed belt and road routes.

It's a ambitious foreign policy. It  extends infrastructure investment-- roads, railways, ports, power plants and fuel pipelines-- in countries along the old Silk Road  in Tang Dynasty to Europe and it's maritime counterpart.

It would maintain closer economic ties, deepen political trust, enhance cultural exchanges, encourage different civilizations to learn from each other and flourish together.

In the past year, over 50 countries have joined this program. We believe it will promote mutual understanding,peace , friendship and development of this area.

Sharing bike is increasing popular in my city.

You can find a large number of bicycles easily when you need to take one.Moreover, it's not expensive even high school students can  consume it every day. It's convenient for people to park it anywhere when they arrived. It also beneficial to our environment. Increasing people prefer to ride a bike instead of driving private cars.  Ut can relieve the traffic pressure.It helps them to do exercises when they go to work and back home from work.

However, there are some problems existed. Some people are not responsible for these bikes. Some bicycles are broken causing by humans . Some bicycles are parked randomly along the road.

In my suggestion, firstly, the government should implement strict laws and rules for sharing bicycles users to regulate the management. Secondly,  the users should raise awareness of using sharing bike reasonably. Lastly,  the government should build special roads for people to ride bicycles to avoid traffic accidents occurred.

In conclusion, I hope sharing bike can make our life better. Every user has responsibilities to obey the rules .

Mobile payment brings a lot of convenience in our daily life. It's a new trend to pay with electric money. You don't need to take cash when you go out. You can use it from big supermarkets to small fruits stall.Also, you can buy things you like from the internet through mobile payment.

Obviously, it helps us to save a lot of time. You can use mobile phone to pay almost everything such as tax fee, call fee and etc.

But mobile payment has caused safety problems to us. Wechat, Alipay users should keep our passwords carefully. Otherwise your account could be stolen especially you log in the fake website.
