【课堂新坐标，同步备课参考】2013-2014学年高中英语北师大版选修七教学课 Unit20-Period Ⅲ.ppt

●教学目标 (1)熟记学案中所列出的单词和短语。 (2)通过学案中所给出的重点单词和重点短语的学习，让学生能够正确使用这些单词和短语造句。 (3)听懂课文中所给出的听力材料。 ●教学地位 听力是学生感到比较难以掌握的东西。听力训练是英语语言交流的一项基本技能，让学生了解听力技巧和提高听力能力是至关重要的。让学生掌握语法知识是学生学好英语的关键，所以应给学生创设一个语境，让学生理解该语法的应用，而不要让学生死记硬背语法条文，应从理解的基础上去运用这些语法。 ●新课导入建议 通过对学生作业的检查导入本堂新课。 Ⅰ.判断正误 1．Albert Einstains child was born in 1904.(　　) 2．Alexander Fleming invented penicillin.(　　) 3．The worlds first computer needs much energy to work.(　　) 【答案】　1.T　2.F　3.T Ⅱ.语篇理解 1．Whose discovery can be used to save peoples lives according to our text?
