背景知识：台湾大地震发生在1999年9月21日凌晨一点四十七分。地震的震中在台北市西南方150公里处南投县的集集镇，震级为里氏7.6级，当时大多数人都在睡梦中。据报道在台北市人口密集地区有人员伤亡、建筑物倒塌和其他损坏现象。在些次地震中有1,700多人死亡， 8,700多人受伤，12,000座建筑物遭受破坏，100,000人无家可归。据信这是台北上个世纪最严重的一次地震。ii. language points 1. i told myself that i must stay alive.stay alive=be alive活下去 stay是系动词，意思是“保持状态”，和形容词连用。e.g. if you want to stay healthy, eat more vegetables and less meat.2. people were in a great hurry to move away the bricks and stones.in a hurry赶紧;匆忙，相当于hurriedly。如：i went to school in a hurry and left my textbook home= i went to school hurriedly and left my textbook home.move away意为“搬走，离开“的意思。如：he moved the table away from the window.拓展词组：move back 退缩 move on 继续前进 move in搬入 move out迁出3. we should do nothing but walk slowly in the storm.nothing but表示“除了之外什么也不” 如：we could see nothing but water.be nothing to sb./sth.对不算什么，毫无关系 如：both money and honor were nothing to him.do nothing but do只做 如：she does nothing but listen to records.4. mr wu told us to go home early.tell sb (not) to do sth. 叫某人（不要）做某事e.g. mother told us not to stay out too late.5. because ,as, since的区别because 多表示所叙述的理由是复合句的重点，所以它引导的从句常用于回答疑问的直接理由。如：why am i leaving? im leaving because i want to. as, since用于表示理由是已知，而理由以外的内容才是叙述的重点，两个连词引出的句子常置于主句前。since侧重形式，as多表示理由以外的内容才是重点。如： (1) as it is rainy, lets stay at home. (2) since you have no license, you are not allowed to drive. 注意：for引导的句子不置于主句前，用于补充说明理由。如： i will follow his advice, for he is a doctor.iii. grammar(一）过去进行时：past continuous tense1. 现在进行时和过去进行时这两个时态的动词在形式上都是由“be+现在分词”构成，只是过去进行时表示过去某一时刻或某一段时间正在发生的动作，因此be动词由was, were代替现在进行时中的助动词am, is, are。2. 过去进行时的构成：只要把现在进行时中的am/is/are改成它们的进去式was / were就行了。肯定句：主语+was / were + 现在分词 + 否定句：主语+was / were + not + 现在分词 + 疑问句：was / were + 主语 + 现在分词 + ?3. 进去进行时的用法：(1) 表示过去某一时刻正在进行的动作。这时常和at this / that time, this time yesterday, at six last sunday等时间状语连用。e.g. he was watching tv this time yesterday. 昨天这个时候他正在看电视。they were sweeping the floor at four yesterday afternoon. 昨天下午四点他们在扫地。(2) 表示过去某一段时间内正在进行的动作。这种用法往往也有具体的时间状语，或与另一个动作相对应。常与from seven to eleven yesterday morning, the whole evening等状语或以when, while引导的时间状语连用。e.g. what were you doing from two to three yesterday afternoon? 昨天下午2点到3点你在干什么？it was raining all yesterday evening. 昨天整个晚上都在下雨。when they came in, we were doing our homework. 当他们进来时，我们正在做作业。my father was watching tv while my mother was cooking. 我爸爸在看电视而我妈妈在做饭。4. 过去进行时与一般过去时的区别：一般过去时强调事情的结果，已经过去了；而过去进行时更强调事情进行的状态，不一定做好了。过去进行时与一般过去时的区别 (1) 进行时表某一行为的“片断”一般时表示行为的“整体”和存在的状态。 i was reading the book at that time. (未读完，“读”的片段) i read the book yesterday. (已读完，表整个“读”) (2) 一般持续时间状语多与进行时连用 it was raining all night. (优先用was raining ,rained 为持续动词，故也可使用) he was writing a letter the whole of afternoon. (短暂动词与持续时间连用，表反复，连续发生，不可用一般过去时) (3) while 时间状语从句中用短暂动词时只能用进行时。 he broke a chair while he was jumping up and down. (4) while 所在主从句动作大致持续相等时主从句一般都用进行时，但若是持续动词可都用一般过去时，两个动作一长一短时短的用一般时，长的用进行时。 i was cooking the dinner while he was playing the piano. (平行) i cooked the dinner while he played the piano. i saw him while i was walking to the station. （二）while和whenwhile和when都可解释为“当的时候”，大多数时候两者可以互换。e.g. kitty waved to the visitors while/when she was dancing to the music. 当凯蒂随着音乐翩翩起舞时她向来访者挥手致意。但是while引导的从句中必须用进行时态，而when引导的从句并不一定
