Children who spend more time reading with their parents have a greater chance of becoming better readers than those who don’t. With help from their parents, children can learn techniques(技巧) to improve their reading skills.

“A lot of parents think after their child learns to read, they should stop reading to them,” Donna George said. “They are sadly mistaken.”

George offers her services to parents at the Title I Learning Centers. She said reading aloud to children may be the most valuable(有价值的) thing parents can do. “It is better for children to hear things at a higher level than where they are,” George said. “Parents are their child’s first teacher.” Parents help their children build listening, phonics(拼读法), comprehension(阅读理解) and vocabulary skills when they read aloud to them.

Before parents can identify reading problems, they should escape the enemy----television and limit the time their children spend watching television. George suggested not allowing kids to have a TV in their bedrooms, setting a schedule of when kids can watch or keeping a list of how many programs children watch. Louise Joiners said while her 14-year-old daughter and 10-year-old son enjoy reading, the television sometimes becomes a distraction. So she tries to build the situation by suggesting books the entire family will enjoy reading together, like the Harry Potter series.

Parents who do not read themselves should not depend on their children being enthusiastic about it. If parents would read to their children at least 15 minutes every day, children would not have so many problems in school. It is the parents’ job to help build that desire in their children, and of course to know what kind of books to read is also important.

因在预防和控制“非典”斗争中思想不到位、领导责任不落实,2003年4月30日下午,安徽省蚌埠市环保局局长杨军华被停止局党组书记、局长职务,写出深刻检查并通报全市,待问题查清后再作进一步处理。据了解,4月11日,蚌埠市环保局干部刘某因公到苏州、上海出差,18日,该同志未经批准自行去北京办理私事。22日返蚌后未按要求进行登记、隔离,直到27日刘得知所乘航班上有一人被诊断为“非典”疑似病人后才接受隔离观察。蚌埠市委认为,杨军华作为环保局主要领导,在防治“非典”斗争的大事面前思想认识不到位,责任心不强,对本单位外出回蚌人员情况不了解、不掌握,在市里催促处理过程中行动迟缓、措施不力,对刘某一事带来的影响和严重后果负有直接责任。为警示各级干部,把人民群众的利益和生命健康放在第一位,4月30日下午,蚌埠市委决定对杨军华作出上述处理。

请运用行政领导的有关原理分析这一案例,说明行政领导者责任的内容。
