1、精选优质文档-倾情为你奉上八年级下时态总结:过去进行时1. 过去进行时的构成过去进行时由was/were+doing构成2. 过去进行时的用法1) 表示过去某一时刻或过去一段时间内正在进行的动作。常和表示过去的时间状语then,at that time,this time yesterday,at ten yesterday等连用,或用另一动作来表示过去的时间。如:-What were you doing at nine last night?-I was watching TV at that time. He was reading when I came in. I was doing
2、my homework while my parents were watching TV. 2) 过去进行时常和always等表频率的副词连用,表示过去频繁发生的习惯性动作,此时的过去进行时带有一定的感情色彩。如:Alice was always changing her mind. 3. 一般过去时和过去进行时的区别一般来说,如果强调过去某个时候或某段时间曾有过某个(已完成的)动作时应用一般过去时;而如果强调动作在过去某个时候或某段时间内正在进行(是否完成不明确)时则用过去进行时。练习:Part 1 用所给动词的正确形式填空。1. What _ you _(do) at that time
3、?-We _(watch) TV. 2. I _(have) my breakfast at half past six yesterday. 3. While we _(wait) for the bus, a girl _(run) up to us. 4. I _(telephone) a friend when Bob _(come) in. 5. -_ they _(have) a meeting at 4 yesterday afternoon? -No, they _. They _(clean) the classroom. 现在完成时1. 定义:表示现在动作已发生或状态已存在
4、或过去的动作状态持续到现在,一般翻译成“已经”,“.过”2. 构成:助动词have/has+过去分词,助动词have有人称和数的变化。肯定句否定句疑问句简略回答I/ You have worked.I/You have not worked. Have I/you worked?Yes, you/I have. No, you/I have not. He/She/It has worked. He/She/It has not worked. Has he/she/it worked?Yes, he/she/it has. No, he/she/it has not. We/You/They
5、 have worked. We/You/They have not worked. Have we/you/they worked?Yes, we/you/they have. No, we/you/they have not. 3. 用法:1. 表示过去已经发生但对现在情况有影响的动作,常与already, never, up to now, in the lastyears, yet(多用于否定句), just, before等词连用。 He has gone to Beijing. (表示他不在这里。)2. 表示过去开始,持续到现在的动作或状态,常与since, for等连用。We h
6、ave not seen each other for ten years. (没见面的动作从十年前持续到现在。)3. 表示到现在为止,动作发生的状况,如:次数等。Ive been to Shanghai three times. 辨析:Already: 多用于肯定句中,在用于疑问句中时,表示疑惑,惊讶或出乎意料。Just:表示“刚”,一般放在谓语动词之前,表示刚刚完成的动作。 Since:意为“自以来”,后可接表示起点时间的单词,也可接一个时间状语从句,多用于完成时态。Since表示持续到现在,用于完成时;after只表示在某一时刻之后,用于过去时。 只有在It is since这样的句子结
7、构中,主句的谓语才可用一般现在时,一般过去时或现在完成时。 It is ten years since I saw you last time. 现在完成时还可以与“包括现在在内的”表示一段时间的状语连用,表示到说话时动作仍未结束。如:today, this morning (afternoon, evening, week, month, year.), these days等。 表示非延续性动作的动词不能与表示一段时间的状语连用。常见的这类动词有:appear, begin, borrow, buy, close, die, fall, find, finish, join, kill,
8、leave, lend, lose, sell, start, stop等。have been to、 have gone to 和have been in的区别1)have been to “去过某地”,强调说话以前的动作发生过或延续到现在2)have gone to “已去某地”, 强调人已经离开,不在说话现场。3)have been in “已在某地(待了多久)”, 若该地方为小地方,则用at代替in,若后面是there,here等时间副词,则have been后面不需要介词现在完成时练习:1.
