共享單車使用后的注意事項作文及翻譯

幾乎在一夜之間，成都的街頭巷尾被共享單車“攻占”，共享單車因其便捷、便宜和靈活，受到了成都人的青睞。

不過，當它落戶成都后，一系列問題由此產生：共享單車隨意停放、占用人行道；共享單車被人掛上樹、被小偷盜竊、被惡意破壞；騎共享單車摔傷，找不到人賠償……1月9日，成都市交委正式發布《成都市關于鼓勵共享單車發展的試行意見》并公開征求意見，鼓勵共享單車發展，并對共享單車的管理、運營做出詳細規定。

繼風靡北京、上海、廣州等城市后，成都也出現了共享單車，在城市一些地鐵站出入口、重要地標位置，都能見到排列整齊的共享自行車。

不可否認地，這一新興的出行方式能為市民帶來許多便利，使用共享單車，是解決“最后一公里”問題的理想方案。

開車怕堵，走路嫌累……在糾結于選擇何種交通方式時，市民有了共享單車這一更便捷的選擇。

自行車作為一種短距離出行工具，也有助于城市“慢交通”系統的搭建。

搭配步行或者公交車、地鐵等交通方式，共享單車可用作換乘接駁，這不僅節省了市民的出行成本，還對城市的低碳、綠色和可持續發展有不可忽視的推動作用。

共享單車的存在是很有必要的，目前成都已有超過10萬輛共享單車，但單車的運營、停放、維護等一系列問題也接踵而至。

首先，下載APP、綁定手機號、輸入真實身份信息——成都共享單車的取用方法很簡單，使用時按半小時0.5元或者1元進行計時收費，但需要事先繳納99元-299元的押金。

對于電子計費和一次 *** 的押金，很多市民都有“計費會不會有誤”、“押金返不回來怎么辦”的擔憂，在使用單車時“望而卻步”。

除此之外，共享單車成天暴露于日曬雨淋之中，其租用過程中發生的質量損壞、遺失被盜的責任界定問題，也是市民的一大使用顧慮。

同時，共享單車也存在亂停亂放的現象。

一些單車使用者缺乏責任心，在城市車站、軌道交通站點等交通集散地，以及學校、醫院、商場等人員流動性強、密集度高的場所周邊區域非停車區域停放單車，對公共資源進行非法占用，反而新增了城市交通擁堵。

因此，共享單車的興起是有利有弊的，促進共享單車的良性發展，不僅要依靠市民公共道德意識的提高，更離不開相關部門的制度規范。

對于亂停亂放、損壞共享單車的行為，要和使用者的個人信用掛鉤，鼓勵企業建立個人信用體系和獎懲制度勢在必行。
