材料一：某市在经济发展、社会进步的同时，面临着以下问题：     

◆房价上涨比较快，中低价位、中小户型房屋严重供不应求；     

◆10%最高收入家庭的财产总额是10%最低收入家庭的30倍；   

◆某些政府公职人员失职渎职，“官煤勾结”，煤矿事故频繁发生；     

◆多家化工企业严重污染环境，市民怨声载道；     

◆刑事发案数居高不下，社会秩序不稳定。    

该市政府坚持“忧民之所忧、乐民之所乐”的理念，构建社会主义和谐社会。 针对上述问题在网上公开征集市民建议，开展“市民论坛”活动，问计于民。

 （1）假如你被选为该市“市民论坛”代表，请就该市所面临的问题向政府提出几条合理化建议。

材料二：根据《行政许可法》和有关政府信息公开规定，城．市建设规划等群众关心的重大事项，有关政府机关应及时向社会公开。然而，当市民真的去有关部门查询这些政府信息时，却频频遭遇“红灯”。前不久，郑州一市民因查询有关停车位规划许可文件被拒，不得不将郑州市城市规划局告上法庭，要求其按照法律规定，公开相关文件。

 （2）我国政府推动政务信息公开有何意义？
