1、1还没现在完成时的讲解和练习对所学时态的回顾，引入现在完成时通过数轴来概括讲解所学的四个时态：一般现在时、现在进行时、一般过去时、一般将来时。（导入）有时候，这 4 种时态还不能满足我们表达的需要。比如：表示“某人过去曾经做过某事”或者“某人做某事多久” ，以上五种时态就派不上用场了。这时，我们可以用一种新的时态现在完成时表示。同样也用数轴来表示一下。一 现在完成时的构成:主语 + have/has + 过去分词 (过去分词:规则动词的过去分词构成与动词过去式相同;不规则动词需要特殊记忆。略 )Exercises1 选择填空( )1.I Enghish in this school since
