It was raining when they left the station. 做题时常见错误如下： 一、易把 be＋现在分词记成 be＋过去分词 例：He was talked （talk） to his mum at that time． 答案：was talking 解析：过去进行时与现在进行时结构上的区别体现在 be 动词上。 二、丢掉 be 动词或忘记把动词变成现在分词 例：1 I watching （watch） TV when he came in． 2 They were play （play） games at 5：00 p．m． yesterday． 答案：1 was watching 2 were playing 解析：现在进行时中“be＋现在分词，缺一不可”的规律也可应用于过去进行时。 三、对动词或动词词组提问时丢掉 doing 例：We were flying kites at 5：00 p．m． yesterday． （对划线部分提问） What were you at 5：00 p．m． yesterday? 答案：What were you doing at 5：00 p．m． yesterday? 解析：现在进行时中“What……doing……”?句式同样适用于过去进行时。 四、易与现在进行时弄混 例：My mother is cooking （cook）when I got home． 答案：was cooking 解析：这两种时态的共同点是都表示动作正在进行，但现在进行时前提是现在，而过去进行时 前提是过去，由 when I got home 可看出前提是过去。 五、易与一般过去时弄混 例：昨晚我在读一本故事书。 I read （read） a story book yesterday evening． 答案：was reading 解析：这两种时态的共同点是都用于表示过去发生的动作。但过去进行时强调动作正在进行， 而一般过去时则表示过去某一时间所发生的动作或存在的状态，它表示的动作往往已经完成。“在” 说明正在进行，而“I read a story book yesterday evening．”的意思是昨晚我读了一本故事书， 言下之意已经读完了。故用过去进行时。 另外，在宾语从句中当主句为过去时，从句若是现在进行时，需变成过去进行时。 e．g． He said that he was drawing a cat at noon yesterday． 海到无边天作岸，山高绝顶我为峰。 5 练习（Exercise） 一 、单选 （ ）1 What ______ from three to four yesterday afternoon?

He has just seen the film. 2.以 ever 和 never 为标志 ever 和 never 表示到现在为止动作或状态曾经或从来没有发生过。 This is the best film I have ever seen. 这是我曾经看过的最好的一部电影。 He has never been to Beijing. 他从没有到过北京。 3.以动作发生的次数为标志 若某一动作到现在为止已经发生了若干次，则要使用现在完成时。 He says he has been to the USA three times. 他说他已经去过美国三次了。 4.以 so far 为标志 so far 往往表示到目前为止动作或状态已经发生。 He has got to Beijing so far. 到目前为止他已到了北京。 She has passed the exam so far. 到目前为止她已经通过了考试。 Part three： 过去已经开始的动作一直延续到现在，甚至有可能继续延续下去，我们可以从动作 “延续”的特性和“时间”点段的区分入手，进一步学习现在完成时。 ①“终止”、“延续”要转换 ★★英语中的动词从词义上可以分为延续性和非延续性两种。在现在完成时态中一定 要注意动词这一特性，应将这类非延续性动词转换为延续性动词。如： 海到无边天作岸，山高绝顶我为峰。 9 “Cats” has been on for half an hour. 《猫》已经开演半个小时了。 How long have you had this dictionary? 这本字典你买了多久了? （common）常见的有： leave --- be away borrow --- keep buy --- have die --- be dead begin/start --- be on finish --- be over fall ill ---be ill get up---be up catch a cold --- have a cold put on→ wear come/become/go --- be here fall asleep --- be asleep get to/ arrive/reach --- be (in) get to know --- know join----be a member of ... (成为… 的一员) open ---be open close ---be closed ②时间“点”、“段”须分清 过去开始的动作可以延续到某一点结束，也可能继续延续，这时就要根据时间“点”、 “段”选择相应的介词 for 或 since。如： He has been away for two years. 他已走了两年。(for +时间段) He has been an English teacher since 1992. 自从 1992 年以来他一直当英语教 师。 (since +过去某一时刻) 练习（Exercises）： A) 选用 have, has 填空： 1.

They have not / haven’t bought a computer. 5. — Has he lost his book? — Yes, he has. / No, he has not / hasn’t. 海到无边天作岸，山高绝顶我为峰。 10 重难点：（TIPS) I. 比较 since 和 for since 后接时间点， for 后接时间段，试比较： I have lived here for more than twenty years. I have lived here since I was born. My aunt has worked in a company since 1949. I have not heard from my uncle for a long time. II. 比较 have/has been to、have/has gone to 和 have been in have(has) been to...表示“曾去过某地，已经从那里回来了”，可以和 ever、never、 twice 等连用。have(has) gone to 表示“已经去了某地，在去那里的途中或到达那里 还没有回来”。have(has) been in 表示“在某地呆多长时间”，常与表示一段时间的 状语连用，如：since, for, how long 等 He went to Shanghai last week 上周他去了上海 He has been to Shanghai. 他(曾经)到/去过上海.(但他人现在肯定不是在上海而是回来了) He has gone to Shanghai. 他已经去上海了.(也许刚动身出发,也许已经到了,也许还在路上,反正他人不在这 里) Mr. Brown has been in Shanghai for three days. 布朗先生来上海已经有三天了 练习（Exercises） 一、延续性动词和瞬间性动词之间的转化 1.He died 10 years ago. ——He ______________ for 10 years / since 10 years ago. 2.He borrowed the book 2 weeks ago. ——He _____________the book for 2 weeks. 3.He bought the motorbike a month ago. ——He ___________the motorbike for a month. 4.He arrived here three days ago. —He ____________here since three days ago. 5.They turned off the light 2 hours ago. —— The light __________for 2 hours. 6.He left here 2 years ago. ——— He ____________from here for 2 years. 7.The film began 30 minutes ago. ——The film __________ for 30 minutes. 8.They opened the door an hour ago. —— The door __________ for an hour. 9.They closed the door an hour ago. ——The door ___________for an hour. 10.He joined the army last year. 海到无边天作岸，山高绝顶我为峰。 11 ——He _____________ a _______ for a year. 二、单项选择。 （ ）1.The famous writer _____ one new book in the past two year .
