1、比喻说明法。用如此生动形象、贴近学生生活实际的比喻来纠错，学生学得愉快，记忆深刻，很快地就化解了这一教学难点。2练习法。练习是增强对知识点理解、掌握的一种主要方法，做练习最关键的是讲究选题的针对性，不然，不但不能提高学习效率，而且还影响对知识的理解和深化。3、多媒体辅助教学法。在传统教学中，一些抽象、难以用言语来描述的问题，通常让许多老师感到棘手。而多媒体课件由于其形象直观特点，能使抽象东西形象化，既突出重点，又能使难点化难为易，从而使学生对所学知识记得牢，兴趣盎然，增加美感。4、游戏活动法。教师在课堂上，应从学生的心理和生理特点出发，充分利用小学生模仿力强、求知欲强、记忆力好、表现欲和创造力强等特点，围绕教学中的难点、重点，设计生动活泼、有趣多样的学习活动，寓教于乐。有的放矢才能提高成效。要使检测效益最大化，教师需要在充分考虑大多数学生认知能力、知识水平和能力素养的前提下，分层次设计检测内容，灵活方式、适时进行检测，并且及时评价，让学生获得成功的愉悦，呵护学生的求知欲，激励学生积极进取。第三学时Using LanguageReading, listening and speaking仔细阅读“Andythe Android”，然后根据课文内容选出最佳答案。1From the picture we can guess the passage is about _Aa football match between humansBa football match between androidsCa football match between humans and androidsDa basketball match between androids答案：B 2Whos Andy?AA dog.
