Top student Lin Yijian had a problem recently . The 14-year-old boy from Xiamen used to get marks of over 110 points （out of 120 possible points）on his math tests . But during last semester’s final exams , his math score was only 90 points .

It was a shock . “I didn’t know what happened , ”said Lin , who kept feeling nervous and frustrated（沮丧的）about math during the following month. .

Like Lin , many of us have setbacks（挫折）in life . What would you do to deal with these setbacks ? Would you just let them be and give up ？

Lin chose to face his problem . His parents and teacher also gave him help . After some hard work he now gets marks between 100 and110 points on his math tests . Although he still isn’t at his original（原来的）level , Lin doesn’t panic anymore .

“Don’t be scared by setbacks ,”he said . “You will beat it . ”

Chen Xingzhu in Shenzhen also has a story to tell . The 15-year-old girl is not good at doing sit-ups（仰卧起坐），which is necessary for the coming high school PE entrance exam（体育中考）. One has to do at least 35 sit-ups in a minute to pass the test . Most of Chen’s classmates can do 40 . However , Chen could only do 20 .

Feeling worried , Chen decided to do something . She did sit-ups for half an hour every day after school . Now , after a month , she can do 30 sit-ups a minute .

“I finally found what made me slow through continuous （持续的）practice and then improved little by little , ”said Chen . “I believe next month I will be able to do 40 !”

民众作为城市的主人和管理服务的对象，对公共政策制定应该享有重要的发言权，但在现实生活中，有些部门往往不尊重甚至忽视、削弱这样的发言权。因为事前征求民意、听取民意不够，所以公众对一些城市管理决策不知情，更谈不上什么理解与支持。也因为事前被忽略的声音没有被及时“打捞”，被压制的意见表达不畅，一旦决策执行过程出现问题，公众的质疑与批评便喷涌而出。
这段文字针对的主要问题是______。

A．公共事务决策忽视民意
B．民众对公共政策制定没有发言权
C．民众对城市管理决策不知情
D．城市管理政策遭到公众质疑与批评
