帮我改改语法错误～Hainan is a beautiful place,it is the second larges

Hainan is a beautiful place,it is the second largest island.[这句话两套主谓,少连词 改法1：将it改为which——定于从句.改法2：it前“,”改为“.”i大写]The water is clear and the sky is blue.All the year round,there are many coconut palm trees,and you can on the long beaches do some watersports.Hainan is a populer city ,[同第一句错误一样 改法1逗号改称句号 改法2：在逗号后加where 表示前一句在从句作地点状语 I think you should visit to there .（to应该去掉) There are many ways of traveling(也可写作travelling 英美用法) such as by plane,by train,by car and people can choose any of ways of traveling[前面已经提过 of travelling 省去更好] if they like.you [y大写]can go there by plane,because it’s very fast.
I hope you will have a good time in Hainan!
不知道你现在上几年级 不过要是高中作文显得水平不是很高 要是初中就比较好 从句运用不够熟练 不过有几处写的不错[if you like 这个省略句用得很好]
