Dear fellow students,
I'm Li Hua,a senior two student.Now I'm appealing to you to focus more attention on shared bikes,of which the popularity has been considerably increasing.(高分句型一)【共享单车的现状】
Benefits of shared bicycle riding are obvious:they never produce pollution,thus encouraging low﹣carbon lifestyle.Convenience is also why people are in favor.Additionally,public bikes are almost free of charge while other forms,taxi for example,are quite expensive.【共享单车的好处】But still,problems cannot be overlooked.The main concern is that random parking frequently bothers others a lot.Worse of all,bikes of this kind are left damaged for unknown reasons.【共享单车存在的问题】
So,considerate parking is what enables everyone to enjoy the public facility.(高分句型二)And please keep in mind that when using,one should take good care of shared bikes rather than destroying the properties.A small action can make a huge difference.Everybody counts! 【提出的倡议】
Sincerely yours,
Li Hua
