Dear Sir/ Madam, Envirnmental prblems are becming mre and mre serius all ver the wrld. With the develpment f the sciety, there are t many cars n the streets in ur city. Cars have made the air unhealthy fr peple t breathe. Black smke and pisnus gas are given ff by factries. Factries als put waste int the river. And wherever we g, we can find rubbish.Nw mre and mre peple have realized these prblems. I think that gvernments shuld clse dwn the factries and develp laws t stp peple frm driving cars every day. I suggest everyne in this twn shuld help t clean up the river and the streets. We shuld call n everyne in the twn t thrw rubbish in the dustbins. I hpe the prblem will be slved in the near future and ur hme will becme better and better.
Dear friends, In rder t make the envirnment mre beautiful, we shuld d what we can t prtect it. First, we shuld plant mre trees and flwers t make ur city mre beautiful. Als, always remember nt t thrw rubbish r pur waste water everywhere. As we all knw, water is becming less and less. S it’s quite necessary t save water. Fr example, turn the tap ff after washing. Last but nt least, we’d better ride bikes r walk when we g ut instead f driving cars. In my pinin, if everyne tries his best t prtect the envirnment, ur city will becme nicer and cleaner. Thank yu! Wang Lin
