阅读课教学设计
教材分析：
本课是高一英语必修三第四单元的阅读课，教材通过对宇宙大爆炸理论进行科学性分析，推断出地球生命的由来以及生物进化的过程，文章最后讲述的现象发人省醒：The?earth?may?become?too?hot?for?the?lives?on?it.它关系到地球上生命的未来。
本文所使用的文体是说明文，简要的介绍了地球形成的几个重要阶段，并使用了大量的表示时间概念的连词以及介词短语来使得全文过度自然，条理层次清晰，在学生练习阅读技巧的时候要加以重视这些连接词。在对教材的处理上，我准备以自学以及小组探究的方式采用任务型教学法，使全体学生在能够运用跳读以及细读的方法对课文有较好的理解。在此基础上，部分学习能力强的同学语言输出表达和写作能力。
学情分析：
高一年级的同学经过上一学期的学习，对于高中学习方式以及培养的能力都有了一定的认识。在阅读技巧方面，大都学生已经掌握了如略读、跳读、细读等阅读技巧，能在短时间内找到关键词和关键句；在学习习惯方面，经过一学期的学习，大多数学生对新课程教改的自学以及探究学习方式都能熟练的操作，团体作战精神比较强，好胜心也比较强，乐于表现自己，这都为本课的顺利完成提供了良好的基础。但是由于基础不一样，并且地球起源这个话题对于大部分学生来说是陌生的，有的由于初中特别是基础差占时落后的学生，所以这也要求我们在设计学案的时候要难度设计要层层递进，区别对待基础不同的学生。?
