6、esterday .昨天12点，他正在厨房烧饭。用法：1）过去进行时表现过去某一时刻正在进行的动作。eg. She was writing a letter when I came in .我进来时，她正在写封信。2）过去进行时还表示过去某阶段正在进行的动作。eg. They were waiting for you yesterday .他们昨天一直在等你。2. 现在分词的构成1）一般动词在词尾加-ing，读i，如gogoing。2）以不发音字母e结尾的动词，先去掉e，再加-ing。 comecoming makemaking writewriting3）以重读闭音节结尾的动词，如果末尾以一

7、个辅音字母结尾，应先双写这个字母，再加ing，x和w结尾的除外。 如getgetting swimswimmingshowshowing4）以字母y结尾的单词，直接加ing。 如carrying、playing、studying。5）以字母ie结尾的动词，变ie为y，再加ing。 diedying lielying6）以元音字母加e结尾，或以e结尾，且e发音的动词，直接加-ing 。 seeseeingbebeing3. 使用进行时态的注意事项1）一些动词，如see、hear、love、like、know、remember；understand、have等表示感情、知觉和状态的词，一般不用于进

8、行时态。2）在there和here引起的句子中，常用一般现在时代替现在进行时。 eg. Here comes the bus . There goes the bell .4. 过去进行时和一般过去时的区别1）过去进行时表示过去正在进行的动作，而一般过去时则表示一个完整的动作。如： They were writing letters to their friends last night .昨晚他们在写信给他们的朋友。（没有说明信是否写完） They wrote letters to their friends last night .他们昨晚写了信给他们的朋友。（表达了他们已写好的意思，整个

9、写的过程已完成。）2）当动作延续较长时间时或表示厌烦、赞美等感情色彩时，常用过去进行时表示。如： He was thinking more of others than of himself .他考虑别人的比考虑自己的多。（表示说话者赞扬的口气） The boy was always making trouble then .那时，他总是惹麻烦。（表示说话者厌烦的口气）5. 以when和while引导的时间状语从句1）延续性动词和非延续性动词延续性动词指动作可以延续一段时间，而不是瞬间结束。如：work、study、drink、eat等。非延续性动词指动作极为短暂，瞬间结束。如：start、b

10、egin、hit、jump、knock等。2）在本单元中，出现了以when和while引导的时间状语从句。 when表示“当的时候”。从句中既可用延续性动词，又可用非延续性动词，这些动词既可以表示动作，又可表示状态。从句中的动作既可和主句的动作同时发生，又可在主句的动作之前或之后发生。如：Mary was having dinner when I saw her .The boy was still sleeping when his mother got home yesterday morning . while表示“在的时候”、“在期间”。它强调主句的动作与从句的动作同时发生或主句的动作

11、发生在从句的动作过程中。while从句中必须是表示动作或状态的延续性动词。如：The weather was fine while we were in Beijing .She called while I was out .如果主句的动作在从句的动作过程中发生，从句常用进行时。如。While we were swimming someone stole our clothes .Dont talk so loud while others are working .总结： when可指时间点，又可指时间段，从句中可用延续性动词，也可用非延续性动词。 while总是指一个时间段，从句中必须用

12、延续性动词。6. In this unit , well learn how to tell a story . Lets take section B 3a as an example .1）Listen to this story 听这个故事Linda Jacobs loves her dog Davy . They went to New York City last Saturday . While Linda was buying a newspaper at the train station , the dog got out of his box and ran away .

13、The station was crowded and Linda couldnt see Davy anywhere . When Linda shouted his name , some people looked at her but Davy didnt come . Then she called the police . While she was talking on the telephone , Davy met another dog outside the station . While the police were coming , Linda walked aro

14、und the station and called Davys name . She didnt think about looking outside the station . Finally , a little boy said to her , “Did you look outside ? I saw a big black dog when I came in .” When Linda finally saw Davy , he was jumping and running with another dog . There was a police officer next

15、 to them . The police officer said to Linda , “I think my dog found your dog .”注意事项：a. 交代清楚故事发生的时间、地点及人物。人物：Linda and her dog Davy ; A police officer and his dog ; A boy地点：at the train station时间：last Saturdayb. 正确运用时态Linda loves her dog Davy .在这句话中，表明了一种持续的状态，用一般现在时。They went to New York City last S

16、aturday .在这句话中，讲的是发生在上周六的事情，因此，时态是一般过去时。一个故事中，时态的变化不应太大，如果故事发生在过去，一般都用过去的某种时态。又如：When Linda finally saw Davy , he was jumping and running with another dog .在这句中，用过去进行时。c. 注意运用一些顺序词，如First , then , next , Finally , at the same time（与此同时）, after that（从那以后）恰当地运用这些连接词，能够使文章流畅，通顺，增色不少。Ex : P22 Section B
