So far I have ridden HelloBikes for many times. It is good for our health. And it is also convenient to rent with the help of an app. Most importantly, it is very convenient to park as well. If more people travel in this way, it will keep the environment cleaner. But we need to park it in a proper place.So, I advocate going green and traveling light to make the world a better place.

我提倡綠色出行。公共單車對我們的健康有益，用App就可租用很，最重要的是停車方便。

The bike is a popular means of transportation. Nowadays, more and more people take the shared bikes to go to work or school. We need to make full use of these bikes easy to be found everywhere in Ningbo.

當(dāng)下公共單車非常流行，許多人騎車去工作、去學(xué)校。我們需要加大對這些單車的利用率。

The shared bikes can help reduce the air pollution. However, it also has some disadvantages. The bikes are exposed to the sun and rain, and will function badly soon. It will cost a lot to repair them. What’s more, some people will park them disorderly, which worsens the traffic.In my opinion, we should use them in a proper way.

盡管共享單車可減少空氣污染，但常年暴露在太陽和雨水下，容易損壞，需要花費(fèi)資金修理，隨意停放極易造成交通堵塞，需要合理使用。

The shared bikes also have some shortcomings. They will be broken if they cannot be repaired soon enough. Sometimes they will be parked on the sidewalks. Generally speaking, shared bikes do more good than harm, so I hope more people will use them.

壞了不能馬上維修，隨意停放，是共享單車的缺點(diǎn)。總而言之，希望更多人善用他們，讓共享單車發(fā)揮的優(yōu)勢大于劣勢。
