英语语法—现在进行时(基本).doc

现在进行时元音：a e i o u（其它为辅音）现在进行时表示动作发生的时间是“现在”，动作目前的状态是“正在进行中”。所谓“正在进行中”，是指在谈到这件事的时候，这个动作还在进行中。至于它是什么时候开始的，什么时候会停下来，不是我们关心的。所以“正在进行时”的事件，可能发生几年了，也可能只有几分钟。仍在进行中这是“正在进行时”的关键所在。它是一件持续进行的事情。一定义：现在进行时的定义：现在进行时表示现在或当前一段时间正在进行的动作。可以表示有计划的未来，也就是用现在进行时表示将来。二构成：现在进行时的构成是:主语+be+v.ing现在分词形式。be的变化在现在进行时中，be 要根据人称代词和名词的单复数不同，而分别使用am/is/are，即：I am/he/she/it 包括单数名词和不可数名词用is,you/we/they 包括复数名词用are.第一人称单数：I+am+doing+Sth.第一人称复数We+are+doing +Sth.第二人称单(复)数 You+are+doing+Sth.第三人称单数 He（She，it）+is+doing+Sth.第三人称复数 They+are+doing +Sth.三现在进行时的变化肯定句式：主语+be( am, is, are)+现在分词+其它.否定句式：主语+be(am, is, are) +not +现在分词+其它.一般疑问句：Be(am, is, are) +主语+现在分词+其它？特殊疑问句：疑问词+be(am, is, are)+主语+现在分词+其它？对现在进行时的特殊疑问句的回答，它不可以用Yes或No直接作答，要根据实际情况回答。现在进行时用法口诀主语在句首，am, is, are跟在后，现在分词跟着走，其他成分不可丢。表示动作正进行，句中now时间定。一般问句，把be提到句前去。否定句式也简单，be后只把not添。四现在分词加ing的规则现在分词是在动词后加上ing 构成。如:starting,working, coming, sitting 等都是现在分词。现在分词的变化规则是固定的，大家用心记一下就可以了。(1)直接在谓语动词后加ing. 例如：going, starting, working.(2) 以不发音的字母e结尾的动词,去掉字母e，再加ing，如 come-coming make-making ride-riding have-having take-taking write-writing dance-dancing 注意：如果单词结尾的e发音，则不能去掉，也直接加ing. 例如：see -seeing/agree - agreeing .(3) 以重读闭音节（重读闭音节即两个辅音中间夹一个元音并且重读的音节）结尾，呈现 “辅，元，辅”结构的动词，双写末尾的辅音字母，再加ing 。如run running stop stopping cut cutting control controlling（4）以ie结尾的动词，把ie变为y，再加ing，如lie lying die dying tie - tying另外，有少数动词比较特殊，请用心记住：例如： picnic - picnicking.5)少数以-c结尾的动词变为现在分词时和过去式，须先将-c变为ck,然后再加-ing 。如：picnicpicnicking traffictrafficking五时间状语：可用来表示现在进行时的时间状语，常用的有：now, this week, at this moment 等；或者告诉你一个准确的现在时间，或者用look, listen提醒听者注意正在发生的事。例如：They are playing basketball now.现在他们正在打篮球。Listen! She is singing an English song.听，她正在唱英语歌。Look at the picture. The children are flying kites in the park.看这幅图。那些孩子正在公园放风筝。We are making model planes these days.这些天我们在做飞机模型。Its 6:30 now. I am getting up. 现在是6：30.我正在起床。现在进行时练习一、按要求改写句子1.
