A

This is a true story from Guyana. One day, a boy took a piece of paper from a box. He made a paper ball and pushed it into his nose. He couldn’t get it out. He ran crying to his mother. His mother couldn’t get the paper out, either. A week later, the paper was still in the boy’s nose. His nose began to have a bad smell.

So his mother took the boy to a hospital. The doctor looked up at the child’s nose, but she couldn’t get the paper out. She said she had to cut the boy’s nose to get the paper out.

The boy’s mother came home looking sad. She didn’t want her child to have his nose cut. The next day she took the boy to her friend Sidney who lived in a house with an old lady called May. May wanted to see the child, so the child let her look up his nose.

“Yes, I can see it,” May said. “It will be out soon.”

As she spoke, she shook some black pepper on the child’s nose. The child gave a mighty sneeze and the paper flew out. His mother was surprised. May told his mother to take the boy to the seaside for a swim, for the salt water would go up his nose and stop the bad smell.

So the lucky boy didn’t have to go to the hospital to have his nose cut.

阅读关于"全球气压带和风带的分布"的图文资料，按要求完成教学设计任务。材料一《普通高中地理课程标准（实验）》的内容标准要求："绘制全球气压带、风带分布示意图，说出气压带、风带的分布规律"。材料二某版本教科书中关于"全球气压带和风带的分布"的内容。（三）全球气压带和风带的分布形成地球上近地面气压带和风带的主要因素有两个：热力因素和动力因素。热力因素指赤道附近因受热较多，形成低气压带；两极地区则因为寒冷低温，空气收缩，密度增大，形成高气压带。高空的气压形势正好相反，在赤道上空形成高气压带，两极上空的气压则相对较低。受地球自转偏向力的影响，赤道上空向南北分流的气流，在南北纬300附近的高空积聚，迫使那里的空气产生下沉运动，在近地面形成高气压带。这种空气运动就是气压带形成的动力因素。在热力因素和动力因素的综合作用下，地球表面就形成了赤道低气压带、南北极两个高气压带，以及南北半球两个副热带高气压带（南北纬30°附近）。而在极地高气压带与副热带高气压带之间，形成两个相对的低气压带--副极地低气压带。低纬环流和信风带以北半球为例，从图可以看出，赤道低气压带上升的暖气流在高空由南风逐渐右偏成西南风，在北纬30°附近偏转成西风，导致"堆积"效应，产生下沉气流，使近地面形成副热带高气压带。在近地面，空气由副热带高气压带向南北流出。向南的一支流向赤道低气压带，逐渐右偏成为东北风，形成东北信风带。同理，在南半球，则形成东南信风带。东北信风与东南信风在赤道附近辐合上升。这样，在赤道与副热带地区之间形成两个低纬环流圈的同时，又形成了南北半球的两个信风带。中纬环流与西风带在近地面，从副热带高气压带流向更高纬度的一支气流，在地转偏向力作用下右（左）偏成西南（西北）风，最终偏转成与纬线基本平行的西风，称为盛行西风。西风在副极地低气压带与高纬的极地东风相遇之后上升分流，向低纬方向流动的高空气流，流向副热带高气压带的上空，随后转为下沉气流，形成完整的中纬环流。高纬环流与极地东风带从极地高气压带流向低纬的气流，在地转偏向力的作用下右（左）偏形成东北（东南）风，最后偏转成为基本与纬线平行的绕极地流动的东风，称为极地东风。盛行西风与极地东风在南（北）纬60°附近相遇，相对暖而轻的西风气流爬升到高空，形成副极地上升气流。上升气流到高空，又分别流向南北。流向高纬方向的气流在极地地区下沉，于是在副极地与极地之间构成了高纬环流。
