1) That probably does not seem much to you or me, but it is a rapid increase when compared to other natural changes.
译：_________________________________________________________________________.
when compared to other natural changes是一个省略的时间状语从句，其完整的形式应该是______________________。在时间、地点、条件、方式或让步状语从句中，如果从句和主句为同一主语，或者从句的主语是it,而且从句中的谓语动词时动词be或含有助动词be，可省略_________________.如：
（1）If (it is)so, you must get back and get it. 如果是这样，你必须回来取。
（2）Although (he was) criticized, he still worked hard.尽管他受到批评，他依然卖力地工作。
2) There is no doubt that the earth is becoming warmer and that it is human activity that has caused this global warming rather than a random but natural phenomenon.
译：_________________________________________________________________________.
There is no doubt that…是一个常用句型，意为“确信…，无疑…”，但There is (some)doubt之后常接________引导的从句，表示“怀疑是否会…”。例如：There is still some doubt whether he is fit for the job.至于他能否胜任工作，还有疑问。

After class（课后巩固提高、预习准备）
1.Discuss the statement: We should do nothing about global warming. Follow these instructions:
1).Get into groups of six. Decide which three in your group are going to agree with the statement (Group A)and which three are going to disagree with the statement (Group B).
2).Group A students discuss why they agree with the statement; Group B students discuss why they disagree.
3).Group A and B get together. They tell each other the reasons for agreeing or disagreeing with the statement.
2. Read the reading passage carefully and try to find the new grammatical structure in it.
【设计意图】课后的分组讨论属于任务拓展的较高层次，可以进一步训练学生运用本节课掌握的语言知识和相关信息发表自己看法、实现语言输出、解决实际问题的能力，找出新的语法现象是预习作业，旨在为下节语法课做好准备。
教学反思
本节课的设计最大的特点是充分考虑了高二学生已较丰富的语言知识积累，又已掌握熟练地阅读技能的特点，从训练高二学生循序渐进的掌握有效的阅读策略，使用恰当的阅读技能入手，同时为激发学生的探究欲望和阅读兴趣设置了由浅入深，层层推进的任务型阅读的教学模式。
同时为适应当前素质教育的深入推进的要求和出于对英语课堂教学和英语学习大面积提升和促进的要求，为鼓励学生主动学习，积极学习，我们采取了课前课中课后的这样一种阅读课教学模式，课前自主学习，合作探究；课上交流展示、研讨提升；课后巩固提高、预习准备，我们希望通过这样的课堂设计过程，通过老师所创设的这样一个教学流程和情境，让学生通过自己的探索、研究，解决问题、获取知识。从而真正达到学生自主学习、合作学习、探究学习、积极学习的目的。
另一个特点是教学环节的设计层次分明，衔接流畅自然。整个的教学活动清楚地划分成读前、读中、读后3各阶段，并且，每个阶段的设计思路明确，读前活动体现背景知识的激活和语言准备，读中活动突出阅读技能、阅读策略的训练，读后活动指向语言的应用和话题的拓展。整个环节的设计由浅入深，由表及里，层层深入，步步为营，使阅读活动从整体到部分最后回到整体，理解的层次也由读懂到读深最终到读透。

教学反思
本节课内容比较多，很多词汇、短语、语法需要记忆，但为了让学生不至于产生厌烦情绪，设置了多种形式学习，让学生在学习语言知识的同时，及时归纳词汇和语法的用法，掌握多种学习方法，这样就比生硬的说教效果要好。
同时为适应当前素质教育的深入推进的要求和出于对英语课堂教学和英语学习大面积提升和促进的要求，为鼓励学生主动学习，积极学习，我们采取了课前课中课后的这样一种教学模式，课前自主探究，合作学习；课上交流展示、研讨提升；课后巩固提高、预习准备。我们希望通过老师所创设的这样一个教学流程，让学生通过自己的探索、研究，归纳、总结，解决问题、获取知识。从而真正达到学生自主学习、合作学习、探究学习、积极学习的目的。
总之，本节课的设计顺应全省规范办学行为、深化课程改革、推进素质教育的要求；更新教育教学观念，积极引导学生的课前自学，充分落实学生课堂的主体地位；积极引导学生学习方式的转变，倡导学生的主动学习、自主学习、合作学习和探究学习，是一节较高效的课。

本部分通过学习学生感兴趣的话题——地球变暖，使学生进一步意识到环境保护的重要性和紧迫性。然后通过听录音进一步加强学生保护环境的责任感。因为此课的话题很生动，难度不高，听力部分也是如此，而且听力的内容紧接阅读文章的内容，学生很感兴趣。
本课是阅读、知识点讲解加听力课，重点是通过阅读材料，理解文章的内容后对该话题进行理解，然后进一步深化该话题，掌握有关的单词短语的用法，同时进行相关的听力训练。
教学内容主要有以下几个方面：
1. 通过书信引出本课的话题——地球变暖。
2. 通过速读完成主旨大意的归纳，细读完成细节信息的处理，训练提高学生的阅读能力。

以 Solutions to slowing climate change 为题，写一篇短文， 下面范文供参考。
Global warming does not have to occur. It is possible for the human race to slow down global warming and maybe even remove all of the effect that people have on the climate.
One of the solutions is to increase the number trees on the earth. Trees could take in the carbon dioxide through its life processes. The trees would fix carbon, changing the atmospheric carbon into organ carbon. The more trees are growing on earth, the less carbon dioxide will be in the atmoshpere.
The solution to reducing this source of carbon dioxide release would be to change where energy comes from. Less carbon would be sent out if fossil fuels were used properly. This could be done by increasing efficiency. Efficiency could be improved in a variety of different places it would be possible ot heighten efficiency in all areas of energy production, distribution, and use.
Climate change would be much easier to countrol if people understand how it happens and how global warming can be reduced. Education of the public will make people support the governmental actin and take an active part in reducing global warming.

随着新课程的实施，素质教育的推行，学生的课时减少了、课余时间增多了。为了营造高效课堂，使学生高效学习，结合我市英语教学改革的实际，本节课的教学分为课前、课中、课后三个阶段，课前预习实施四化：即预习任务具体化、适量化、指导化、监督化；通过课前的充分预习和作业的认真完成，从而实现课堂教学的大容量、快节奏与高效益；课上学生探究、合作、展示；课后留有适量的作业。
教师要重视写前的“导”和学生的“学”，有效的激发学生积极的学习动机。教师不仅仅是知识的传授者，而且是引导者和组织者，要帮助学生开展自主性学习和发展学生学习情感，充分体现了以学生为中心的教学理念。写作过程要充分体现新课标所倡导的“合作与交流”的新理念，要使协作交流真正成为教学的一部分。一方面，学生通过相互倾听、互帮互助，提高了学习的积极性，另一方面，学生之间的启发和交流通常会采用同龄人比较容易接受的方式，效果往往比教师讲解更好。更为重要的是，只有通过学生自身的体验和感知，所学到的知识才能最终内化并提升为能力。学生在讨论中互相提供信息，交流思想，共同完成学习过程，这在传统的写作课堂中却很难做到。评价要有利于引导学生对学习行为和结果进行检测和反馈，有利于培养学生的自主学习的能力。写作是语言的输出，更是情感的交流，思维的碰撞，心灵的交互。
“冰冻三尺非一日之寒”。英语写作能力的培养和提高，并非一蹴而就。它有赖于扎实的语言基础、正确写作方法的引导和大量的写作实践。因此教师应从狠抓学生的基本功入手，适时对学生进行英语写作方法的指导，充分调动学生的学习积极性，钻研教材，创造良好的课内外语言环境，实现教师、学生、教材和课堂的最优化，一定能有效地促进学生写作能力的形成。

（2）Although (he was) criticized, he still worked hard.尽管他受到批评，他依然卖力地工作。
2) There is no doubt that the earth is becoming warmer and that it is human activity that has caused this global warming rather than a random but natural phenomenon.

教学反思
本节课的设计最大的特点是充分考虑了高二学生已较丰富的语言知识积累，又已掌握熟练地阅读技能的特点，从训练高二学生循序渐进的掌握有效的阅读策略，使用恰当的阅读技能入手，同时为激发学生的探究欲望和阅读兴趣设置了由浅入深，层层推进的任务型阅读的教学模式。
同时为适应当前素质教育的深入推进的要求和出于对英语课堂教学和英语学习大面积提升和促进的要求，为鼓励学生主动学习，积极学习，我们采取了课前课中课后的这样一种阅读课教学模式，课前自主学习，合作探究；课上交流展示、研讨提升；课后巩固提高、预习准备，我们希望通过这样的课堂设计过程，通过老师所创设的这样一个教学流程和情境，让学生通过自己的探索、研究，解决问题、获取知识。从而真正达到学生自主学习、合作学习、探究学习、积极学习的目的。
另一个特点是教学环节的设计层次分明，衔接流畅自然。整个的教学活动清楚地划分成读前、读中、读后3各阶段，并且，每个阶段的设计思路明确，读前活动体现背景知识的激活和语言准备，读中活动突出阅读技能、阅读策略的训练，读后活动指向语言的应用和话题的拓展。整个环节的设计由浅入深，由表及里，层层深入，步步为营，使阅读活动从整体到部分最后回到整体，理解的层次也由读懂到读深最终到读透。

（四）文化意识及情感态度目标
通过了解人类当今面对的环境问题，了解节约能源、保护环境的重要性，从而树立保护环境的意识。
方法运用
本节课将采用新课标所提倡的“任务型教学”途径，侧重于提高学生在语言知识学习中的归纳能力，以及对所掌握语言知识的灵活运用，同时培养学生自我完成任务的能力。
按照高中英语课程标准所倡导的以学生为本的教学理念，采用任务型语言教学途径，促使学生积极运用语言，完成任务；采用词组翻译、句子理解翻译、通过句子辨析词义，在完成练习的过程中达到巩固词组以及语法的用法的目的。。

教学反思
本节课内容比较多，很多词汇、短语、语法需要记忆，但为了让学生不至于产生厌烦情绪，设置了多种形式学习，让学生在学习语言知识的同时，及时归纳词汇和语法的用法，掌握多种学习方法，这样就比生硬的说教效果要好。
同时为适应当前素质教育的深入推进的要求和出于对英语课堂教学和英语学习大面积提升和促进的要求，为鼓励学生主动学习，积极学习，我们采取了课前课中课后的这样一种教学模式，课前自主探究，合作学习；课上交流展示、研讨提升；课后巩固提高、预习准备。我们希望通过老师所创设的这样一个教学流程，让学生通过自己的探索、研究，归纳、总结，解决问题、获取知识。从而真正达到学生自主学习、合作学习、探究学习、积极学习的目的。
总之，本节课的设计顺应全省规范办学行为、深化课程改革、推进素质教育的要求；更新教育教学观念，积极引导学生的课前自学，充分落实学生课堂的主体地位；积极引导学生学习方式的转变，倡导学生的主动学习、自主学习、合作学习和探究学习，是一节较高效的课。

以 Solutions to slowing climate change 为题，写一篇短文， 下面范文供参考。
Global warming does not have to occur. It is possible for the human race to slow down global warming and maybe even remove all of the effect that people have on the climate.
One of the solutions is to increase the number trees on the earth. Trees could take in the carbon dioxide through its life processes. The trees would fix carbon, changing the atmospheric carbon into organ carbon. The more trees are growing on earth, the less carbon dioxide will be in the atmoshpere.
The solution to reducing this source of carbon dioxide release would be to change where energy comes from. Less carbon would be sent out if fossil fuels were used properly. This could be done by increasing efficiency. Efficiency could be improved in a variety of different places it would be possible ot heighten efficiency in all areas of energy production, distribution, and use.
Climate change would be much easier to countrol if people understand how it happens and how global warming can be reduced. Education of the public will make people support the governmental actin and take an active part in reducing global warming.

随着新课程的实施，素质教育的推行，学生的课时减少了、课余时间增多了。为了营造高效课堂，使学生高效学习，结合我市英语教学改革的实际，本节课的教学分为课前、课中、课后三个阶段，课前预习实施四化：即预习任务具体化、适量化、指导化、监督化；通过课前的充分预习和作业的认真完成，从而实现课堂教学的大容量、快节奏与高效益；课上学生探究、合作、展示；课后留有适量的作业。
教师要重视写前的“导”和学生的“学”，有效的激发学生积极的学习动机。教师不仅仅是知识的传授者，而且是引导者和组织者，要帮助学生开展自主性学习和发展学生学习情感，充分体现了以学生为中心的教学理念。写作过程要充分体现新课标所倡导的“合作与交流”的新理念，要使协作交流真正成为教学的一部分。一方面，学生通过相互倾听、互帮互助，提高了学习的积极性，另一方面，学生之间的启发和交流通常会采用同龄人比较容易接受的方式，效果往往比教师讲解更好。更为重要的是，只有通过学生自身的体验和感知，所学到的知识才能最终内化并提升为能力。学生在讨论中互相提供信息，交流思想，共同完成学习过程，这在传统的写作课堂中却很难做到。评价要有利于引导学生对学习行为和结果进行检测和反馈，有利于培养学生的自主学习的能力。写作是语言的输出，更是情感的交流，思维的碰撞，心灵的交互。
“冰冻三尺非一日之寒”。英语写作能力的培养和提高，并非一蹴而就。它有赖于扎实的语言基础、正确写作方法的引导和大量的写作实践。因此教师应从狠抓学生的基本功入手，适时对学生进行英语写作方法的指导，充分调动学生的学习积极性，钻研教材，创造良好的课内外语言环境，实现教师、学生、教材和课堂的最优化，一定能有效地促进学生写作能力的形成。
