现在进行时 上课使用.ppt

Consolidation 1.我们用现在进行时表达“某人正在做某事” 可以表示说话时正在进行或发生的动作，也可表示当前一段时间内的活动或现阶段正在进行的动作。 2.如果句子带有鲜明的时间状语，如now（现在），或带有Look和Listen等暗示词，或有上下文语境时，我们用现在进行时。 3.现在进行时的基本结构是主语+be+v-ing。动词ing形式。 4.现在进行时的否定句是在be后加not. 5.现在进行时的一般疑问句是把be提前至句首。 * 表示现在（说话瞬间）正在进行或发生的动作。 You are listening to me now. 现在进行时 也表示当前一段时间内的活动或现阶段正在进行的动作。 He is writing a book these days. 构成：助动词 be(am/ is/are)+动词-ing形式 即：be + doing What is he doing now? He is dancing. 当我们描述一个正在发生的动作时要用 现在进行时 (present continuous tense) I am eating. You/ We/ They are eating. He/ She/ It is eating. 一、现在进行时肯定句和否定句的构成： 肯定句: 主语+ am/ is /are + v-ing ... 否定句: 主语+ am/ is / are not + v-ing ... I am not eating. You/ We/ They are not eating. He/ She/ It is not eating. Work out the rule! 动词ing(现在分词)的构成规律 二、动词ing形式的构成： + ing 大多数动词 think → thinking - e + ing 以不发音e 结尾的动词 take → taking -ie + y + ing 以ie 结尾的动词 lie → lying 双写辅音字母+ ing 某些以“一个元音字母+ 一个辅音字母”结尾的动词 run → running swim → swimming get → getting 现在分词用途多，进行时态不可缺。 它的构成很好记，动词后缀ing。 词尾若有哑音e，去e再加没问题。 一辅重读闭音节，这个字母要双写。 还有一点要注意，改ie为y再加ing。 写出下列动词的现在分词形式 read — look — dance — write — sit — get— lie— tie— reading dancing writing sitting getting looking lying tying 1.
