1、四种进行时态,学习点拨：我们前面所学的四种时态，表达的只是时间概念。本课所学的进行时态除时间概念外，又加入了某种感情色彩。我们可以形象地比喻：使用一般时态像听录音机，使用进行时态则像看电视机，而后者所具备的功能正是画面，这恰恰是一般时态和进行时态的不同之处。此外，进行时态给我们的是一种暂时性。理解以上两点是非常重要。,一、进行时态的构成,is(am,are)doing,was(were)doing,will be doing,would be doing,二、现在进行时态和过去进行时态,(1).Who are you waiting for?你在等谁呢？(2).She is having di
2、nner in the restaurant.她正在饭馆吃饭。(3).He was studying English in the library yesterday evening.昨天晚上他在图书馆学英语。,1.表示动作的进行。,2.进行时态的暂时性进行时态与一般时态的比较(1)They live in America.（一贯的）(2)They are living in America.（暂时的）,(3)My TV works perfectly.我的电视非常好（一贯的）(4)My TV is working perfectly.我的电视目前很好。（暂时的）,第二句给人的印象是：电视过去
3、工作不正常，最近修了一下，效果很好。,第二句给我们的感觉是，他们一直住在别的什么地方，但目前暂住美国。,3.进行时态的感情色彩。进行时态除了一个进行的动作以外，更多的是带有一种“态”，也就是说一种情态在里面。试着比较下面的两个句子：(1)More and more people buy TV sets.(2)More and more people are buying TV sets.,第一个句子只是说出一个现象，第二句却给了一个生动的画面，试图让我们看到人们购买电视机的情景。,进行时态与一般时态的比较(1)My wife always watches TV in the evening.（
4、说明事实）(2)My wife is always watching TV in the evening.（表示不满）(3)He does fine work at school.（说明事实）(4)He is doing fine work at school.（表示赞扬）,进行时态给我们一种画面感，一种情感的流露，具体是赞扬，不满，还是想刺激听话的人要具体情况具体分析。,关于进行时态需要注意的问题,非持续性动词的进行时态形式表示将来时态。(1)His father is dying.她的父亲要死了。(2)The spring is coming.春天要来了。,可以这样用的动词还有：come,
