Passage 1
These days,many large city buildings are equipped with their own air-conditioning systems.These systems help keep the buildings cool,but they can also damage the environment.Since they?use a lot of electricity,for instance,they contribute indirectly to global warming.In addition,the?water that flows through the systems is often cooled using chemicals called chlorofluorocarbons,or?CFCs,that are believed to damage the Earth′s ozone layer.Recently,though,a system has been?built in the city of Toronto,Canada,that cools buildings with little damage to the environment.
In the traditional air-conditioning systems found in most large buildings,water is pumped?through the building in a continuous cycle.The water is first cooled to a temperature of 4℃in?machines called chillers.It is then sent to individual units that cool the air in each room.As the?water flows through the building,it gradually becomes warmer.Finally,it reaches the roof,where it?is left to cool down naturally in a water tower.After that it is returned to the chillers,where the cycle?begins again.
Toronto lies on the shore of Lake Ontario,one of North America′s Great Lakes,and the new?system makes use of cold water taken from about 80 meters below the surface of the lake.At this?depth,the water in the lake remains at 4℃all year round.This is exactly the temperature to which?the water in air-conditioning systems is cooled.However,the water from the lake is not pumped?directly into the air-conditioning systems.Instead,it is used to cool the water that is already inside?the air-conditioning systems.After that,the lake water is added to the city′s ordinary water supply.
Enwave,the company that developed this deep-lake cooling system,says that it uses 75 percent?less energy than traditional air conditioning.And since no CFCs are used,no damage can be caused?to the ozone layer.Not every city is located next to a large lake,but experts believe that systems like?the one being used in Toronto could be built elsewhere by using other natural sources of cold water.
What is one problem with traditional air-conditioning systems?查看材料
细节题。短文第一段指出传统的空调系统会对环境造成伤害，其中一个危害就是“In?addition．the water…using chemicals called chlorofluorocarbons…believed to damage the Earth’s ozone layer”，即在水冷却过程中使用的CFCs会破坏地球的臭氧层。故选D。
请根据《我们的微电影》为课题 1.请写出一篇规范、完整的课时教学简案。2.恰当设定本科的教学目标、教学重点和难点。 3.合理地设计的学习活动和作业要求。4.至少设计三个课堂提问。
案例 王老师在高一素描人物基本结构练习时，发现一位学生方法特殊。他不是按照王老师所要求的以写实性素描进行描绘，而是坚持表现自我主观感受，画面产生了“另类”效果、对此，王老师让该学生在全班同学面前阐述这样画的理由，并介绍自己的体会。 问题: 请对王老师在教学中的做法进行评价和分析。
案例 李老师为《美丽的蓝印花布》单元课教学准备中，创设的“情境”是: 江苏某地地处美丽富饶的长江三角洲冲积平原，气候温宜，山清水秀。在千百年的历史中，当地人民创造并发展了丰富多彩、名扬四方的民间工艺，蓝印花布便是其中最具代表性的民间工艺品之一。为此，当地准备进行一场“传统工艺发布会”以推介蓝印花布。根据上述情境、李老师设计了两个“问题”:蓝印花布是怎么做出来的?有哪些代表性的手工艺人? 问题: 请对李老师创设的“情境”和“问题”进行评价并给出改进意见。
