5. 重点、难点分析
过去进行时:表示在过去某一时间内正在进行 的动作。 构成:was / were + 现在分词 ( 其中was是am、is的过去式,were是are的 过去式) e.g. 1) I was doing my homework then . 那时,我正在做作业。 2) He was cooking in the kitchen at 12 o’clock yesterday . 昨天12点,他正在厨房烧饭。

3)过去进行时表现过去某一时刻正 在进行的 动作。 e.g. She was writing a letter when I came in . 我进来时,她正在写封信。 4)过去进行时还表示过去某阶段正在进行的 动作。 e.g. They were waiting for you yesterday . 他们昨天一直在等你。

6. 现在分词的构成
? 1)一般动词在词尾加-ing,读[iη], 如go - going。 ? 2)以不发音字母e结尾的动词,先去掉e,再加-ing。 come - coming make - making 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:get - getting swim - swimming show - showing

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。 die→dying lie→lying 6)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 - seeing be - being

7. 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。 e.g. Here comes the bus . There goes the bell .

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。)

8. 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)

9. 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。

2)在本单元中,出现了以when和while引导的 时间状语从句。 <1> 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 .

<2> 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 . Don’t 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。
