传统的语法教学,通常是先进行语法结构总结概括,再进行操练。而新课标则注重强调过程教学,通过先学习再来总结语法结构和特点。在新课标人教版选修Book6中,虚拟语气分了两个课时(Unit1 和Unit2)来完成.Unit1是对一般现在和将来时的虚拟,Unit2是对过去事实的虚拟,本人对此进行了过程教学尝试。
教学步骤通过与虚拟语气有关的有趣问题导入课题,再归纳总结

Step2归纳概念,总结结构特点。
概念: 虚拟语气(The subjective mood)表示说话人所说的不是事实,而是一种对一般、现在、将来事实的假设、愿望、怀疑或推测。主要用于条件从句,也可用于主语从句,表语从句,宾语从句等。
结构特点:
现在事实的虚拟If 条件从句主句
动词时态过去时(were,did+v, had)Would, could ,might+v
一般将来的虚拟If 条件从句主句
动词时态Were to, did, should+v Would\could \might+v Step3课堂操练
