资料我国环境污染现状令人担忧
据专家估计，中国每年因环境污染造成的损失达到二千八百三十亿元人民币，其中，仅水污染一项，估计一年造成经济损失约五百亿元。
据香港《东方日报》报导，自六十年代至今，中国有环境监测的四百三十二条大小河流中，八成受到不同程度的水体污染，其中大江河经过城镇河段的占二成，支流受污染的占六成，全中国二千八百多个湖泊，凡能接纳城镇污水的，大多出现水体负氧化现象。由于地下水过度开采，京津沪大面积出现土地沉降一点五公尺至二公尺，桂林溶岩区三十米地下水重金属超标十至二十倍。
大气污染造成的经济损失约为二百亿元，由于城市燃煤、工厂排放废气及汽车死气污染，大气中二氧化硫、一氧化碳等有毒悬浮微粒弥漫在城市上空，空气污染导致许多城市肺癌死亡率增至万分之二，全国酸雨覆盖面积已达百分之三十，所有这些损失加起来也等于二百亿元。而生态环境破坏和自然灾害造成的损失估计高达二千亿元，森林覆盖率由四九年的三成左右，现已下降至不足一成四，草原的严重退化，水土流失面积达一百五十五万平方公里，占国土面积的百分之十六。
同时，城镇建设却仍以每年侵占一百五十万公顷土地的速度发展，破坏自然生态平衡，加上自然灾害带来的损失，每年至少损失二百亿元。
其他污染如固体废物排放、噪音污染等造成的损失也高达一百三十亿元。
专家分析表示，造成环境污染引起的经济损失原因众多，但国家工业规划布局失误，调控措施不力和公民环保意识不强是主要原因。
我的体会；
学习了该教案后，我总结体会两点。
一、该教案在教学设计上非常注重学生能力的培养，充分利用教材和多媒体手段逐步引导学生理解课文，并能进一步升华课文的主题，使学生受到心灵的启迪和道德的震撼。一切都水到渠成。
二、教案所附资料可在课堂中充分被学生利用，使他们的讨论言之有据，会使他们更乐于知识的学习和掌握。这点可以作为我今后很好的借鉴
高中英语语法“虚拟语气”的教学设计 一、教材分析： 本课是结合外研社版高中英语教材选修6中有关虚拟语气的语法内容，进行高三虚拟语气的复习，教学中将语法知识的传授和语言基本技能的学习结合到一起，注重复习语法与语言的运用。采用任务型教学法和小组合作探究学习法，从而扩大课堂的语言输入量及学生的语言输出量。 二、学情分析： 在高一和高二英语学习基础上，高三学生已经掌握基本的语言结构和一定程度的听说读写能力。在高三语法复习的过程中，结合学生原有的知识掌握水平，巩固基础强化正确使用语法知识，提高学生运用语言的深度和难度.但大部分学生的基础知识仍然较为薄弱，运用英语进行交际活动的能力较差，主动学习的动力不够，然而他们学习比较认真，渴求知欲旺盛，思维比较活跃。部分学生的基础较好，能主动配合老师。只有设置使他们感兴趣的活动，因材施教，才能让他们投入到课堂活动中来。 三、教学重点: 1.复习的重点---语法虚拟语气的句型结构. 2.语法虚拟语气的运用 四、教学难点: 1.结合复习的语法知识，以课堂教学为依托，全面训练学生的听、说、读、写能力，加强和提高运用英语的综合能力。 2.虚拟语气在真实的生活语境中的使用。 五、教学目标: 1.知识目标: 引导学生掌握情态动词在虚拟语气之中的使用。培养学生通读，分析，理解，综合的能力，教会学生体察语境，结合上下文，附和逻辑推理和合理的想象，结合语法和题干中的语境解决高考题。在运用语言过程中培养学生的观察力、分析力、想象力和自学能力，提高思维能力和运用英语的综合能力。 2.能力目标： 利用多媒体手段营造积极和谐教学氛围，使学生进入情景之中，充分调动学生的思维活动和情感体验，规范学生运用英语知识准确表达的能力，同时，发展学生综合语言运用的能力，分析问题和解决问题的能力，培养学生自主学习。 3.德育目标： 用情态动词和虚拟语气的句子结构表达思想感情和正确的世界观、人生观。 六、教学策略:
高中英语语法教案（全套）高中英语语法教案 2、冠词和数词 2.1不定冠词的用法 冠词本身不能单独使用，也没有词义，它用在名词的前面， 帮助指明名词的含义。英语中的冠词有三种，一种是定冠词，另 一种是不定冠词，还有一种是零冠词。 不定冠词a（an）与数词one同源，是\" 一个\"的意思。 a用于辅音音素前，一般读作［e］，而an则用于元音音素前， 一般读做［en］。 1）表示\" 一个\"，意为one ；指某人或某物，意为 acertain 。例如： Amr.Lingiswaitingforyou. 有位姓凌的先生在等你。 2）代表一类人或物。例如： Aknifeisatoolforcuttingwith. 刀是切割的工具。 mr.Smithisanengineer. 史密斯先生是工程师。 3 ）组成词组或成语，如 alittle/afew/alot/atypeof/apile/agreatmany/manya/as arule/inahurry/inaminute/inaword/inashortwhile/afte rawhile/haveacold/haveatry/keepaneyeon/allofasudden 等。 2.2定冠词的用法
定冠词the与指示代词this ,hat同源，有\"那（这）个\"的意思，但意义较弱，可以和一个名词连用，来表示某个或某些特定的人或东西。 1）特指双方都明白的人或物。例如：Takethemedicine. 把药吃了。 2）上文提到过的人或事。例如： Heboughtahouse. I\'vebeentothehouse. 他买了幢房子。我去过那幢房子。 3）指世上独一物二的事物，如thesun，thesky ，themoon，theearth 等。 4）与单数名词连用表示一类事物，如thedollar 美 元;thefox 狐狸；或与形容词或分词连用，表示一类人：therich 富人;theliving 生者。 5）用在序数词和形容词最高级，及形容词only , very，same等前面。例如： wheredoyoulive? Iliveonthesecondfloor. 哪？我住在二层。 That\'stheverythingI\'vebeenlookingfor. 我要找的东西你住在那正是 6）与复数名词连用，指整个群体例如:
