Global warming全球变暖全英文介绍

One of the effects of global warming is the destruction of many important ecosystems.Changing and erratic climate conditions will put our ecosystems to the test, the increase in carbon dioxide will increase the problem. The evidence is clear that global warming and climate change affects physical and biological systems. There will be effects to land, water, and life. Already today, scientists are seeing the effects of global warming on coral reefs, many have been bleached and have died. This is due to warmer ocean waters, and to the fact that some species of plants and animals are simply migrating to better suited geographical regions where water temperatures are more suitable. Melting ice sheets are also making some animals migrate to better regions. This effects the ecosystems in which these plants and animals live. Several climate models have been made and they predict more floods (big floods), drought, wildfires, ocean acidification, and the eventual collapse of many ecosystems throughout the world both on land and at sea. There have been forecasts of things like famine, war, and social unrest, in our days ahead. These are the types of effects global warming could have on our planet. Another important effect that global warming will bring is the loss and endangerment of many species. Did you know that 30 percent of all plant and animal species alive in the world today are at risk of extinction by the year 2050 if average temperatures rise more than 2 to 11.5 degrees Fahrenheit. These mass extinctions will be due to a loss of habitat through desertification, deforestation, and ocean warming. Many plants and animals will also be affected by the inability to adapt to our climate warming.

《ai ei ui》教学设计 （一）知识与技能 1、会认读“ a、i ei、ui ”三个复韵母，渗透发音方法。 2、会认读“ a、i ei、ui ”的四声。 3、能在四线三格中正确的书写韵母ai、ei、ui。 （二）过程与方法在游戏、活动中，让孩子们去尝试、去发现、去合作、去探究，使他们亲身经历整个学习过程。 （三）情感、态度、价值观 从拼读音节中体验学习的成就，激发起学生学习语文的热情和欲望。 由于复韵母aieiui 是由两个单韵母合成的，学生容易发成两个单韵母的音，学生对复韵母的发音方法掌握不够，因此我将掌握 3 个复韵母的音、形、四声及标调方法作为本课时的教学重点。给ui 标调作为本课时的难点。 一、激趣导入，温故知新。 1、师： 同学们，你们还记得我们学过的这些朋友吗？（出示单韵母卡片）这六个兄弟住同一个家，他们的家有个名字，叫什么？（单韵母）齐读： 兄弟六人是一家，共同名字叫“单韵母”。 2、师：今天，老师又给大家带来三位新朋友，你们想认识他们吗？我要把第一个新朋友先介绍给我的好朋友，谁愿意做我的好朋友？（师与生紧紧地挨在一起）问：老师和这个小朋友在干嘛？（生答）对了，我跟她是好朋友，紧紧地挨在一起，请小朋友们和你的同桌也紧紧地挨在一起，做好朋友好吗？（生做动作）师：小朋友们挨在一起学习，多好哇！哪个韵母发“挨着”的“挨”这个音呢？我们现在就来学习。 二、引导发现，自主探究。

（一）学习复韵母ai 1、师： 先看黑板。（贴上单韵母玄”的卡片，让学生认读，离卡片远一点贴单韵韵母i的卡片，让学生认读。）（老师挪动“i ”的卡片紧挨在卡片N ”的右边，就组成了复韵母ai。） 2、师： 谁会读？（指名读） 师： 谁知道这个音是怎么发出来的？（指名说） 师： 看老师的嘴形（师范读ai。）教发音方法： 先张大嘴巴发a的音，然后滑向i，中间气不断，一口气读成ai o（带读，指名读，齐读） 3、记住ai 师： 我们会读了，怎么才能记住它呢？（两人挨着aiai; a在前，i在后，紧紧 挨着是朋友；） 4、课件出示第一幅图。（学习标调歌） 师：请同学们观察这幅图，你从图上发现了什么？（出示句子： 姐弟挨在一起比高矮。）（挨”和矮”头上出示未带调的ai）师： “挨”就是复韵母ai 的第一声，“矮”就是复韵母ai 的第三声，那这个声调帽子应该戴在谁的头上呢？（指名答）（师讲单韵母妈妈标调的故事）（课件出示： aoe,标调时，按顺序，iu并排标后边）（带读、齐读）
