We will go when he comes. 二、现在进行时表示说话时正在进行的动作. e.g. He is playing basketball.2. 表示目前一阶段正在进行(但说话时不一定在进行)的动作: e.g. We are preparing for an exam these days.,一般现在时与现在进行时的区别进行时强调动作正在进行,而现在时强调动作的经常和反复,或特征,这类动作没有时间性的.某些表示感官知觉的动词如: see, hear, smell, taste等表示感觉,用一般时,不用进行时.e.g. Can you see a plane in the sky? 注意:1) feel 可以用一般时和进行时表示说话时的感觉: e.g. How are you feeling today? I feel tired. 2) see, hear 有相应表示动作的动词 look at / listen to , 这些词可以用进行时 比较: Can you see a map on the wall? He is looking at a map on the wall.,3. 有些表示状态或心理感觉的动词一般不用现在进行时,而用一般现在时表示状态或感觉,如 love, like, hate, want, need, wish, know(知道), understand(懂得), remember(记得), believe, mean(意味着), think(认为), feel(认为), fit(合适), find(认为), show(表明), have(有) e.g. I know you are right. I want to visit them tomorrow.

I didnt know he was your father. 2)描述已故之人的动作或状态用一般过去时. e.g. Edison invented the electric light.2. 表示过去经常反复发生的动作. He often swam when he was young.3. 表示主语过去的状态或特征. e.g. It was rainy last week. He was a taxi driver many years ago.,练一练： 1. What happened to Mary? - She_ (fall) off her bike and _(hurt)herself 2. Sam _( live) in the small town for five years during the war. 3. It has been 3 years since I _(see) you last time. 4. He wont tell us where he _(get) the book.,fell,hurt,lived,saw,got,五、 过去进行时 表示过去某一时刻正在进行的动作. e.g. He was doing shopping this time yesterday. We were having a discussion at that time.2. 表示过去某一阶段正在进行的动作. e.g. Peter was playing chess the whole afternoon yesterday. We were having a meeting from nine to eleven yesterday.3. 用与 when, while, as引导的表示过去的从句: (注意,这样的动词必须可以持续) e.g. While I was watching TV, the telephone rang.,As we were leaving, some of our friends arrived. When we were playing on the playground , it began to rain. 过去进行时与一般过去时的区别: 过去进行时强调过去某时刻或阶段动作的进行, 不表明动作的完成, 而一般过去时表示过去某动作已发生,表明动作已完成.e.g. He was writing a composition last night.(作文不一定完成) He wrote a composition last night.(作文肯定写完了),六、 现在完成时构成： 助动词have / has + 动词的过去分词用法： 1. 表示某一个动作对现在的影响和结果。e.g. I have already finished my homework. They have bought a new house. 常用的时间状语：already, just, yet 2. 表示从过去某一时间开始，一直持续到说话时，而且动作还在延续， 常与 “ for+ 时间段 ” 或 “ since + 时间点 ” 的时间状语连用。e.g. We have learned English for five years/since 2012. He has taught here since he came here.,III. 现在完成时与一般过去时的区别： 1) 完成时强调过去发生的动作的结果和影响；而一般过去时强调动作发生的时间，地点，方式等，与现在没有联系。e.g. I have just had breakfast. I had breakfast five minutes ago. (时间） I have finished my homework. I finished my home at home. （地点） 2）现在完成时表示的持续状态强调持续到说话时为止， 与现在有联系， 而一般过去时表示的持续状态强调过去某段时间的经历， 与现在没有联系。,e.g. The Greens have stayed in China for a year. The Greens stayed in China for a year during the war. I have learned computer for some time. I learned computer for some time while I was in Beijing.,分析比较,I saw this film yesterday. （只说明动作发生在过去。） I have seen this film. （强调对现在的影响，电影的内容已经知道了。） She has returned from Paris.（她已从巴黎回来了。） She returned yesterday. （她是昨天回来的。） He has been in the League for three years. (在团内的状态可延续) He joined the League three years ago.
