1、现在进行时时态讲解 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。构成现在进行时的构成是:主语+be+v.ing现在分词形式第一人称单数 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+
2、Sth.第三人称复数 They+are+doing +Sth.肯定句:主语+be（is/am/are）+现在分词否定句：主语+be（is/am/are）+not+现在分词一般疑问句:be（is/am/are）+主语+现在分词特殊疑问句：特殊疑问词+相应be动词+主语+现在分词+Sth?变化规则1.直接+ ing(例：sleep+ing sleeping)2.去掉不发音的e+ing(例：bite-e+ing biting)3.重读闭音节，且末尾只有1个辅音字母，双写辅音字母+ing(例：sit+t+ing sitting)4.特殊变化：die-dying,lie-lying，tie-tying5
3、.不规则变化现在进行时的基本用法：A 表示现在( 指说话人说话时) 正在发生的事情例：We are waiting for you.B. 习惯进行：表示长期的或重复性的动作，说话时动作未必正在进行。例：Mr. Green is writing another novel.(说话时并未在写，只处于写作的状态。)例：She is learning piano under Mr. Smith.C.已经确定或安排好的将来活动Im leaving for a trek in Nepal next week.（已经安排了）were flying to Paris tomorrow.(票已经拿到了）D.有些
4、动词（状态动词不用于进行时态）1.表示知道或了解的动词:believe,doubt,forget,imagine,know, remember,realize,suppose,understand2.表示“看起来”“看上去appear,resemble,seem3表示喜爱或不喜爱hate,like.love.prefer4表示构成或来源的动词 be come from.contain,include5表示感官的动词 hear see smell sound taste6表示拥有的动词belong to.need.own .possess.want wish现在分词加ing的规则现在分词是在动词
5、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)去掉词尾不发音的e，再加ing. 例如 leaving,dining.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 .另外，有少数动词比较特殊，请用心记住：例如：lie - lying/die - dying/tie - tying/picnic - picnicki
6、ng.(3) 对于重读闭音节词，双写末尾字母再加ing. 例如：sitting, beginning.这一条规律，必须要弄清什么是“重读闭音节”。下面再举一些双写的例子：run - runningstop - stoppingcut cutting control controlling现在进行时练习题一，写出下列动词的现在分词：play_run_swim_make_go_like_write_ski_read_have_sing_dance_put_see_buy_love_live_take_come_get_stop_sit_begin_shop_二、用所给的动词的正确形式填空：1.Th
