21、 football too hard.将学生分为两个组进行比赛。(2)游戏方法:一位学生通过默读小纸条上的句子做出相应的表情或动作,以此来检测其对于单词、词组成句子的理解。另一位学生通过观察对方的表情、动作等,运用所学提出问题,以此来检测其对于重点句型“Why are you so?/Why do you look so?”的运用。(3)游戏规则:将学生分为两组。A组的一位学生从老师处抽取一张小纸条,根据上面的文字做出相应的表情或动作。B组的一位学生根据A组同学的表情、动作等,运用所学句型来询问他。如: “Why are you so tired?”(4)得分规则。如果B组同学的提问正确,A组同学朗读小纸条上的句子。即A、B两组各得一分。如果B组同学的提问不正确,请A组的其他同学来提问。即提问正确并回答后A组可得两分。2.小组活动Make a sentence 目的:检测学生能否正确运用请求帮助的语句。(1)将关于请求帮助的语句如“Would you mind opening the window?”中每个单词写在一张小卡片上,放在一个信封里。依据学生的人数和能力准备相应的数量的语句。(2)每个小组任取一个信封,每位同学拿出一张单词卡片,大声读出卡片上的单词。(3)全组同学按正确的顺序站成一个横排,一起朗读该句。如果个别语句的单词数量多于该组学生人数,可以一个人负责两张单词卡片。
