讲义初一英语现在进行时讲解和练习题
现在进行时 一、导入 再试一次 有个年轻人去全球著名的微软公司应聘,而该公司并没有刊登过招聘广告。见总经理疑惑不解,年轻人用不太娴熟的英语解释说自己是碰巧路过这里,就贸然进来了。总经理感觉很新鲜,破例让他一试。面试的结果出人意料,年轻人表现糟糕。他对总经理的解释是事先没有准备,总经理以为他不过是找个托词下台阶,就随口应道:等你准备好了再来试吧。 一周后,年轻人再次走进微软公司的大门,这次他依然没有成功。但比起第一次,他的表现要好得多。而总经理给他的回答仍然同上次一样:等你准备好了再来试。就这样,这个青年先后5次踏进微软公司的大门,最终被公司录用,成为公司的重点培养对象。20多年后他成为了公司的总经理。 二、(1)专题讲解 ☆专题1:现在进行时 现在进行时 1、定义:表示现在(说话瞬间)正在进行的动作。 2、时间提示词:now(=right now), look , listen ,It’s …o’clock 等 3、使用情况: 表示说话时正在进行的动作及行为。 4、现在进行时的结构及句型变化 (1)结构:谓语动词结构:be(is ,am ,are)﹢doing(现在分词) (2)现在进行时的句型变化: 肯定句: 主语+be+doing+其它. 否定句:主语+be+not+doing+其它.(be后加not) 一般疑问句: be+主语+doing+其它?(be动词提前) 肯定回答: Yes, 主语 +be. 否定回答: No, 主语 +be+not. 第8页 Eg:肯定句 He is watching TV now.
