过去进行时用来表示过去的某个时间正在发生的动作或过去某一阶段一直进行的动作，其结构为“be 的过去式+ 动词的现在分词”。e.g. Betty was reading a bk when Cindy came in.当辛迪进来时，贝蒂正在看一本书。
I was sleeping when it started t rain.
过去进行时的用法详见本单元语法。本句为一个复合句，从句是由when 引导的时间状语从句，主句为过去进行时，从句为一般过去时。when引导的从句的谓语动作可以在主句谓语动作之前、之后或同时发生。
考题1：[常州] — Why didn’t yu pen the dr fr me, Jim?—I ______ clthes in the bathrm. I didn’t hear the knck.A. am washing B. have washedC. was washing D. washed
【分析】考查动词时态。句意为“—Jim, 你为什么不给我开门？—我正在卫生间洗衣服，我没有听见敲门声”。根据上下文语境可知，此处强调在过去的某个时间正在发生的动作，用过去进行时，结构为“was/were + 动词的现在分词”。
(易错) thusands f 成千上万的e.g. Thusands f peple are planting trees n the hill.成千上万的人正在山上种树。tw thusand 两千
Earthquake kills thusands f peple
当thusand 前有具体的数字时，表示确数，thusand 后不加-s，其后也不用f ；当thusand 前没有具体数字时，表示概数，thusand后既要加-s，也要加f。
考题2：[滨州] —China is a great cuntry with a histry f abut five _____ years.—Yes. And _____ f freigners cme t visit it every year.A. thusand; thusand B. thusands; thusandsC. thusand; thusands D. thusands; thusand
【分析】考查数词的用法。thusand 千，前面要用具体数字，即“数字+thusand + 名词复数”；thusands f + 名词复数，意为“成千上万的……”，表示笼统数字，前面不加具体数字。
accident/'æksɪdənt/ n. 事故，意外的事 e.g. In America abut fifty thusand persns die every year in car accidents.在美国每年大约有五万人死于车祸。

【分析】空白处应填“偶然，意外地”，可用介词短语by accident。
(重点) crash int 撞上e.g. A car crashed int a tree last night.昨晚一辆小汽车撞上了一棵树。The plane crashed int a muntain. 飞机撞上了一座山。She hit him hard n the head. 她狠狠地打他的头。a plane crash 飞机失事
