四种进行时态.ppt

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).

4、n the evening.（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 comin
