Grammar Fcus
   1. 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: wrk、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、knck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 by was still sleeping when his mther gt hme yesterday mrning .
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 ut.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 smene stle ur clthes .Dn’t talk s lud while thers are wrking.
 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。

b: 表示过去某段时间内正进行的动作。e.g. We were building a huse last winter. They were waiting fr yu yesterday.否定句和疑问句：e.g. We were nt sleeping at hme. Was he feeling well?

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 →lying6) 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
4.使用进行时态的注意事项
1)一些动词, 如see、hear、lve、like、knw、 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 cmes the bus.       There ges the bell.
5. 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 t 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 wrte letters t 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)
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 mre f thers than f 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 by was always making truble then .那时, 他总是惹麻烦。(表示说话者厌烦的口气)
含义: 表示过去某个时刻 正在进行的动作。结构： was/were + ding例句：I was having an English class at this time yesterday.
