七年级下学期英语语法：现在进行时态 一、现在进行时(The Present Progressive Tense)的定义：现在进行时是表示现在正在进行或发生的动作或存在的状态，说话瞬间或当前一直正在做着的动作。如：Tony is playing soccer now. 托尼现在正在踢足球。now“现在”，由此可以看出托尼踢球的动作正在进行。二、现在进行时的构成：助动词be+v-ing（动词的现在分词）注意：现在进行时态的助动词be与一般现在时态的be动词用法一致，即：当主语是第一人称I时，助动词用am；当主语是you和复数时用助动词are；当主语是第三人称单数时用助动词is。三、现在分词的构成规律：(1)一般动词后直接加-ing。如：listen-listening, wait-waiting, clean-cleaning, eat-eating(2)以不发音的字母e结尾的动词，去e再加-ing。 如：live-living, take-taking, come-coming, write-writing(3)以重读闭音节结尾，且末尾只有一个辅音字母的动词，双写该辅音字母再加-ing。如：put-putting, get-getting, sit-sitting, swim-swimming, begin-beginning, shop-shopping, cut-cutting, forget-forgetting四、现在进行时的句型结构：(1)肯定陈述句：主语+be(am,is,are)+v-ing+其他。如：They are sitting in the classroom now.他们现在正坐在教室里。(2)否定句式：主语+be(am,is,are)+not+v-ing+其他。如：He isnt playing football.(3) 一般疑问句：Be(am,is,are)+主语+现在分词(动词-ing）+其它？肯定回答：Yes,主语+ be(am,is,are). 否定回答：No, 主语+ be(am,is,are)+not. 如：The girl is swimming.变一般疑问句为：Is the girl swimming? 肯定回答是：Yes, she is. 否定回答是：No, she isnt.(4) 特殊疑问句：疑问词+ be(am,is,are)+主语+现在分词+其它？回答要根据实际情况作答，不能用Yes或No。如：-你现在在干什么？What are you doing now? -我在写故事。I am writing a story.五、现在进行时的句子中常有以下特征词： 句子中有now时，常表示动作正在进行。 Look!或 Listen! 开头的句子，提示我们动作正在进行，用现在进行时。在问“某人在哪里？Where is / are +人? ”时，答语常用现在进行时态表示某人现在正在什么地方做某事。表示当前一段时间或现阶段正在进行的动作，且句中有this week, these days等时间状语时，常用现在进行时。【语法训练】I. 写出下列动词的现在分词：1.eat _ 2.play _ 3.have _ 4.listen _ 5.do_ 6.study _ 7.write _ 8.shop _ 9.swim _ 10.run _ 11.see _ 12.watch _13.come _ 14.put _ 15.begin _ 16.clean _17.live _ 18.take_ 19.talk_ 20.sleep_II. 用所给词的适当形式填空：（请注意观察各句中加黑单词）1.-Is she _ (read) now? -Yes, he is.2.-What are they doing? -They_ (swim).3Look!
