WILD WEATHERMAN

Name: Sam Champion

Hot job: TV Weatherman

Where: WABC-TV, New York City

When you were a child, did you plan to forecast wind, rain, and snow on TV?

I wanted to be a foreign journalist.I took courses in weather science at Eastern Kentucky University, but I majored in broadcasting news.

How did you finally become a weatherman?

My first job in the early 80’s was at the local TV station in Paducah, Kentucky.I did everything from turning on the lights in the morning to writing and delivering morning news.I put together weather forecasts, and became interested in them.

Back then, how did you forecast weather?

Independent companies collected computer information that showed, for example, how a single weather system might split into snow or snow mixed with rain.The information was often opposite and the job of a weatherman was to study the information and make the best educated guess about the storm.

Has weather forecasting changed much with new technology?

Advanced computers, satellites, and Doppler radar (sound waves used to track storms) have made forecasting more exact.But we still know very little about how weather is shaped.So far, we just have theories.

Any advice for children who’d like to become weather scientists?

To me, weather is the most exciting field in the world.There are still so many more questions about weather than answers.After all, if we can’t foresee floods or hurricanes, how safe a society are we? Weather forecasting is wide open for scientists who love to solve puzzling problems.The next generation of meteorologists (weather scientists) will unlock many of Earth’s weather secrets.So get a general knowledge of Earth science, and study meteorology (weather science) in college.

Thanks, Sam.

问答题

A企业只生产一种产品,其产品成本计算采用标准成本计算系统,有关资料如下:

(1)成本计算账户设置

设置“原材料”、“产成品”、“生产成本”等存货账户,均按标准成本计价。

成本差异账户设置9个:材料价格差异、材料数量差异、直接人工工资率差异、直接人工效率差异、变动制造费用效率差异、变动制造费用耗费差异、固定制造费用闲置能量差异、固定制造费用耗费差异、固定制造费用效率差异。

(2)费用分配和差异结转方法

原材料在生产开始时一次投入,在产品直接材料成本约当产成品的系数为1;除直接材料外的其他费用陆续发生,其在产品约当产成品的系数为0.5。

成本差异采用“结转本期损益法”,在每月末结转“主营业务成本”账户。

(3)单位产品标准成本

直接材料(5千克×2元/千克)10元
直接人工(4小时×4元/小时)16元
变动制造费用(4小时×1元/小时)4元
固定制造费用(4小时×0.8元/小时)3.2元
单位产品标准成本33.2元

(4)本月生产及销售情况

生产能量20000小时
月初在产品数量500件
本月投产数量5000件
本月完工入库数量4900件
月末在产品数量600件
月初产成品数量400件
本月销售数量4600件

(5)有关成本计算的业务数据:

月初材料5000千克,本月购入原材料25000千克,实际成本55000元(已用支票支付);

本月生产领用原材料25500千克。

实际耗用工时20000小时;应付生产工人工资85000元;实际发生变动制造费用25000元;实际发生固定制造费用20000元。

要求:

计算购入原材料时所产生的材料价格差异;
