光华化肥厂财务科三名会计都姓刘。老刘是财务科长;大刘负责报表和稽核工作;小刘是出纳。该厂2008年12月发生如下事件: (一)月初,小刘因病请假两周,老刘认为小刘痊愈后,仍从事出纳工作,故责成大刘临时接替小刘工作,双方未办理会计工作交接手续。 (二)在大刘接替小刘做出纳工作期间,销售部负责人拿来一张发票报销,发票内容是在某超市购买价值5万元的办公用品,未附验收证明,大刘明知发票注明的经济内容与实际不符,看到厂领导签字,就予以报销。 (三)为了维护产品销售渠道,厂领导决定在外省市分别设立三个办事处,每个办事处开办费3万元,具体事宜责成小刘办理。 (四)该厂外聘某专家进行技术服务,服务费一年3万元。12月30日,技术科申请专家服务费3万元,财务科小刘根据领导领导指示全额支付,并未按照规定扣缴个人所得税。 (五)为了应对金融危机,该厂决定压缩行政支出,精减行政人员,将原由档案部门保管的历年财务会计档案统一移交财务科进行保管,财务科科长老刘将此项工作交给出纳小刘负责。 (六)为了保证在金融危机的形势下实现明年开门红,厂领导找到财务科长老刘,大刘将已实现的200万元销售收入放在明年一月份反映,老刘欣然同意并责成大刘处理。大刘按领导的要求将已实现的200万元销售收入挂在往来款项中,领导感到非常满意。 (七)年底厂里评选先进时,大刘榜上有名,对此大刘十分感慨地说,这么多年我还是第一次体会到了,不能与领导扭着干,领导让干啥就干啥,让怎么干就怎么干革命,只要两袖清风,就没有问题。

If you want to learn anything at school, you need to listen to your teachers. Unfortunately, millions of kids can’t hear what their teachers are saying. And it’s not because these students are goofing off. Often, it’s the room’s fault. Building architecture and building design can create echo(回声)-filled classrooms that make hearing difficult.

Children with hearing impairments(损伤)suffer most from noisy classrooms. They sometimes can’t hear questions that other students ask in class. Compared with kids with healthy hearing, they have a harder time picking up new vocabulary words by hearing them in talking.

Even kids with normal hearing have a harder time in the classroom when there’s too much noise. Younger children in particular have trouble separating important sounds – like a teacher’s voice – from background noise. Kids with learning disabilities and speech impediments(障碍)and kids for whom English is a second language also have a harder time learning in noisy situations.

In recent years, scientists who study sound have been asking schools to reduce background noise, which may include loud air-conditioners and pipes. They’re also targeting outdoor noises, such as highway traffic. Noise reduction is a big deal. Why? Because quieter classrooms might make you smarter by letting you hear your lessons better.

“It’s so obvious that we should have quiet rooms that allow for access to the lesson,” says Dan Ostergren, a hearing scientist. “Sometimes it surprises me that we spend so much time discussing this topic. I just want to go. Why is this hard for anyone to grasp?”

C.Kids can become smarter after hearing lessons better.
