现在进行和过去进行时.doc

现在进行时1. 现在进行时的基本用法现在进行时主要表示说话人的说话时刻正在进行的动作、不断重复的动作或目前这个阶段(不一定是说话时刻)正在进行的动作。如：Were having a meeting. 我们在开会。(说话时正在进行的动作)Be quiet! The baby is sleeping. 安静，孩子在睡觉。He is teaching in a middle school. 他在一所中学教书。(目前阶段在进行的动作)2. 现在进行时表将来现在进行时表将来，主要表示按计划或安排要发生的动作。如：Im leaving tomorrow. 我明天走。Theyre getting married next month. 他们下个月结婚。现在进行时与一般现在时均可表示将来，区别是。如：用现在进行时表示将来，其计划性较强，并往往暗示一种意图；而一般现在时表示将来，则其客观性较强，即通常被视为客观事实，多指按时刻表或规定要发生的情况。如：Im not going out this evening. 今晚我不准备出去。What time does the train leave? 火车什么时候开? (from )3. 现在进行时表示感色彩现在进行时有时可表示满意、称赞、惊讶、厌恶等感情色彩，通常与 always, forever, constantly, continually等副词连用。比较。如：Shes always helping people. 她老是帮助别人。(表赞扬)She always helps others. 他总是帮助别人。(陈述一个事实)The boy is constantly lying. 这孩子老是撒谎。(表示厌恶)The boy often lies. 这孩子常撒谎。(指出缺点)4. 动词be的现在进行时主要用于表示一时的表现或暂时存在的状态。比较。如：He is foolish. 他很傻。(生性如此)He is being foolish. 他显得很傻。(指一时的表现，并非总是如此)He is friendly. 他很友好。(长期如此)He is being friendly. 他显得很友好。(指暂时的表现，而且不一定真诚)【注】“be+形容词”用于现在进行时时，其中的形容词通常只能是angry, careful, careless, clever, foolish, stupid, kind, friendly, brave, rude, polite等动态形容词，而big, tall, beautiful 等静态形容词不能这样用的。 过去进行时1 过去进行时主要表示过去某个时刻或某一阶段正在进行的动作，常和表示过去时间的状语then，at this（that） time， yesterday，at nine，last night等连用。但在不少情况下，没有表示时间的状语，这时需要通过上下文来表示。 What were you doing at nine last night？ 昨晚九点时，你在做什么？ I called you yesterday afternoon but there was no answer. 昨天下午我打电话给你，但是没有人接电话。 I was visiting a friend of mine most of the afternoon. 我昨天下午大部分时间，都在一个朋友家里。 2 当两个一长一短的动作在过去某时间同时发生时，用过去进行时表示较长的动作。过去进行时可用于主句，也可用于从句。 It was raining hard when I left my office. 当我离开办公室时，雨下得正大。 When you called，I was eating. 你打电话时，我正在吃饭。 When I was cleaning the windows， my brother was sweeping the floor. （当）我在擦窗户的时候，我弟弟在拖地。 Some students were playing football，while others were running round the track. 一些学生在踢足球，同时别的学生正在跑道上跑步。 We were walking along the river when（suddenly） It rained. 我们沿着河边散步，突然下起雨来。 They were watching TV when the lights went out. 停电时，他们刚好在看电视。（注意：同上例） 3 过去进行时表示过去将来的动作 现在进行时可以表示将来的动作，同样，过去进行时也可以表示从过去某时间看来将要发生的动作。常用在间接引语中。 She went to see Xiao Li. He was leaving early the next morning. 她去看小李。他第二天一早就要离开此地了。 She asked him whether he was coming back to lunch. 她问他晚饭是否准备回来吃。 4 过去进行时和一般过去时的区别 过去进行时表示过去某时正在进行的动作，而一般当两个延续动作同时并行时，二者都可用过去进行时表达。 此时的when是连词，与上面第2.3例不同，只能用于句子中间。过去时则表示一个完成的动作。也就是说用一般过去时，只是表示有过这件事；用过去进行时，则强调了动作的连续性。 Li Ming washed the dishes. 李明洗过盘子了。 Li Ming was washing the dishes. 李明在洗盘子。 The children watched TV yesterday evening. 昨天晚上孩子们看了电视。 The children were watching TV yesterday evening. 昨晚孩子们整晚都在看电视。（没干别的） I was reading a novel this morning. 上午我在看小说。（可能没看完） I read a novel this morning. 上午我看了一本小说。（已经看完了） 1.选择填空：( )1.
