请阅读 Passage 1,完成第 21~25小题。Passage 1These 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?
A
The chemicals they use sometimes pollute the water supply.
B
They often damage the buildings that they are trying to cool.
C
There are not enough CFCs in the world to cool all the buildings.
D
The method they use to cool water is thought to harm the ozone layer.

问答题在“1929-1933年经济大危机”内容的教学过程中,某教师设计了如下的导入语:“2008年对中国和世界而言都是不平凡的一年。首先让我们一起来盘点2008年发生的重大事件!这一年8月,中国成功举办了北京奥运会,9月份“神州七号”载人飞船成功发射,中华民族向世界展示了自己的古老文明、开放胸怀和科技水平。与此同时,中国政府面对1月的南方特大冰冻灾害,5月的四川汶川特大地震,9月的三聚氰胺奶粉事件,以及11月的杭州地铁工地塌陷事件,果断行动、群策群力,经受住了严峻的考验。这一年的世界也不太平,巴以冲突升级,索马里海盗猖獗,美国次贷危机引发全球金融风暴……通过盘点,我们发现2008年可谓是多灾多难的一年。但是,回首历史,我们就会发现,人类在发展过程中不缺少灾难,相反,在对灾难的反思中人类不断地认识自然、认识自我、超越自我!这使我想起了中央民族大学敬文东教授的一句话:“我们从不缺少灾难,也从不缺少痛苦,缺少的只是对灾难和痛苦的深入审视、思考与咀嚼。”今天,我们就从对敬教授这句话的思考中来探讨本堂课的问题,这个问题就是:人类如何应对世界性灾难?--以对1929-1933年经济危机解读为例……”。在教学过程中.该教师设计的四个教学环节是:第一,出示三幅图片,再现当时纽约股市崩溃情形下人们的焦虑;第二,出示一则文字材料,师生分析出现经济危机的原因;第三,结合一个表格,分析经济危机的特点;第四,出示大量材料(十幅图片和一则文字材料),展示当时资本主义社会人们贫困失业、无家可归、游行冲突和法西斯势力崛起等现象,为介绍罗斯福新政做铺垫。经过仔细斟酌,又调整如下:第一,出示大量有关1929-1933年经济大危机的感性材料,让学生体验当时的历史氛围。第二,结合所出示的材料,让学生归纳经济大危机的特点。第三,在此基础上,自然而然地提出问题:为什么突然爆发这场史无前例的经济大危机,是偶然的吗?出示材料师生共同研讨。第四,应该怎样解决经济大危机?当时的美国总统胡佛是怎么做的?他为什么要这么做?进而讲述胡佛的坚守传统,并为罗斯福的大胆创新--“新政”做铺垫。问题: (1)上述课堂导入有何特征?这种导入有何作用? (2)该教师对教学过程的调整与所选的教学方法是否合理?说说你的看法。
