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。,现在分词的构成,一般在动词词尾直接加-ing。读/i/，wear-wearing meet-meeting listen-listening look-looking repeat-repeating watch-watching play-playing do-doing 以不发音e结尾的动词，去掉e加-ingcome-coming have-having skate-skating make-making take-taking write-writing,3）以重读闭音节结尾的动词，如果末尾以一个辅音字母结尾，应先双写这个字母，再加ing，x和w结尾的除外。如:,run-running swim-swimming put-putting cut-cutting get-getting begin-beginning shop-shopping kid-kidding,2. 现在分词的构成,4）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 。see - seeingbe - being,3. 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，整个写的过程已完成。）,4. 过去进行时和一般过去时的区别,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、begin、hit、jump、knock等。,5. 以when和while引导的时间状语从句,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 .,5. 以when和while引导的时间状语从句, 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,1. 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。2. while总是指一个时间段，从句中必须用延续性动词。,Unit 3 What were you doing when the UFO arrived?,Period 2,What were you doing atyesterday?,p.m.,a.m.,a.m.,What was she/he doing atyesterday?,Where was Ted at around ten oclock?,be surprised,How strange it was !,He had a very unusual experience.,follow-followed,You can imagine how strange it was !,1,2,3,4,5,Number the pictures in the correct order.,experience 经历；体验,around 大约 (=about),right 正好；恰恰,strange 奇怪的；陌生的,follow 跟随；追随,be surprised 感到吃惊,Isnt that amazing! = That is amazing.
