    Then I would ask them to think of a funny English or Chinese and tell it to partners. While telling stories, they can use expressions and some acting to help make the story funny. 5 minutes would be given to do this.Those stories they told there will be the material for their writing. Soletting them tell it at first is helpful. And they can make a difference between telling a funny story and writing it down. Generally speaking, it is difficult forstudents to write well because they don’t know what to write and how to write. Asking them to tell their own stories at first can help them come up with what to write.After their telling, I would invite someone to share his/her story with all of us and I would write it down on the blackboard.This example story would be used as a sample to illustrate the format of funny story. Different from a story from teacher or textbook, a story from students can obviously become a interesting material to draw students’ attention.Then I would ask the whole class to put this story into several parts. It might be a little bit difficult for them. So I would ask them to find out whether all the sentences are necessary. After delete some sentences, there are 6 sentences left behind. Then they can easily put them into three parts. After interaction with students, I would teach them the right terms for each part and conclude the format of funny story.This step is the key and difficult point in my lesson. So I mainly usetask-based teaching method in this part and the task for students was divided into several stages. With the separated difficult level, students can find there are usually three parts in writing. They can also learn to write without the unnecessary parts in the process of analyzing. And then I wouldn’t rush to tell them the right terms to them directly. Instead, I would ask them to name them by their own. A confused mind is better for acquiring knowledge.While-writing:Then I would give students 7 minutes to write down this story, without other requirements.With all the preparations in pre-writing, students’ difficulties were cleared. So it would be much easier for them to write down the story within 7 minutes. There are no other requirements because students’ first writing is actually a drafting.

    1.促使美国成为一个移民国家的因素是:①美洲属于未开发的新大陆,需要大量的劳动力;②欧洲失业工人和破产农民增加,人们为了追求更好的经济待遇迁往美洲;③新航线的开辟为人们顺利迁移扫除了障碍;④殖民扩张是人口迁移的促进因素,加快了人口迁移的过程。导致美国人口在本土范围内频繁迁移的原因,归纳起来有:第一次人口迁移是战争因素,第二次是城市化;第三次是自然环境、经济环境的变化;第四次是经济格局的变化,即西部和南部新资源的发现和新兴工业的发展。2.我国古代的人口迁移,深受统治者及其行政力量的束缚。封建帝王为了加强本国的经济和军事实力,对人口迁移严加控制。只有当战乱发生的时候,这种控制才得到削弱,人们为了躲避战乱,寻找安定的生活环境,不得不进行大规模的迁移。我国近几十年的人口迁移主要是由生产资料和劳动力数量上的地区分布不平衡造成的,是经济因素在起主导作用,与古代的人口迁移截然不同。

    2.由于附近金矿生产废弃物尾矿砂的堆积,孙家村的大沟里十几年来就吃掉了近百亩土地,使人均耕地下降到0.03公顷。村里和矿上共同商量,共同开发复垦,由矿上出钱,村里出劳力、机械,运来“客土”覆盖到尾矿填平的沟壑上,形成耕地。十年来,通过这种方式恢复耕地15.335公顷,不仅解决了尾矿污染问题,而且村里耕地由25公顷多增加到40公顷。【思考】分析以上两个例子,哪一个体现了可持续发展的原则,为什么?【分析】第二个材料体现了可持续发展。因为材料1用农田堆放垃圾会破坏土地肥力,影响农业生产,又污染环境,危害村民健康。这种行为目光短浅,只顾眼前利益,没有考虑长远发展。材料2既解决了尾矿污染问题,又增加了耕地面积,耕地是可再生资源,利用得当,可为村民提供农产品,解决温饱同时创造经济效益,达到良性循环。所以说保护环境就是挽救人类,我们要将这种意识转化为自身行为,使人地关系走向和谐。
