三、Exercises-动动脑筋
WHAT ARE WE?
　　I have many brothers in my family. Some of us are big, and others are small. Different people in different countries—like different ones in my family.
　　In my family we have three famous brothers. People in Europe and South America like to play one of my brothers. They love him a lot. Especially in Germany, Brazil and the UK, people love him better than in any other countries. They usually play him with feet.
　　In the USA, people love another brother of mine. When they play, they usually have five persons in a team against another.
　　People in China, Cuba（古巴）, Japan, Russia and even in the USA like my third brother. They have very good women teams.
　　Of course I have many other little brothers, too. Some of them are soft, and some of them are hard; some are bigger than an egg, and some are smaller.
　　Do you know what we are?
　　Keys: all kinds of ball sports
　　四、过去进行时与一般过去时用法比较
（1）一般过去式常表示在过去某时发生的动作或存在的状态（包括过去习惯动作），常与一般过去时连用的时间状语有just now, a moment ago, yesterday, last week(month, year), the day before yesterday及表示过去的时间状语从句。如：
I was sixteen yesterday old last year.我去年16岁。
He worked in a factory in 1986.他1986年在一家工厂工作。
I met her in the street the day before yesterday.前天我在街上遇见了她。
He often swam in the river when he was young.他小时侯常在河里游泳。
（2）过去进行时表示过去某一段时间或某一时刻正在进行的动作。常与之连用的时间状语有，at that time/moment, (at) this time yesterday (last night/Sunday/week…), at+点钟+yesterday (last night / Sunday…)，when sb. did sth等时间状语从句。
What were you doing at seven p.m. yesterday?昨天晚上七点你在干什么？
I first met Mary three years ago. She was working at a radio shop at the time.我第一次遇到玛丽是在三年前，当时她在一家无线电商店工作。
I was cooking when she knocked at the door.她敲门时我正在做饭。
（3）一般过去时往往表示某一动作已经完成，而过去进行时却表示动作在持续或未完成。如：
I saw you while you were speaking to the teacher.你在和老师谈话时我看见了你。
注意：有的过去时间状语既可用于一般过去时，也可用于过去进行时，但含义不同。如：
She wrote a letter to her friend last night.她昨晚给她的朋友写了封信。（信写完了）
She was writing a letter to her friend last night.她昨晚一直在给她的朋友写信。（信不一定写完）
五、过去进行时的时间状语
1.when 和while引导的状语从句中，强调某个动作正在进行的过程中时要用进行时态，while表示一段时间，因此它所引导的状语从句中，谓语动词常用进行时态，如：
When/While we were having supper, the light went out.我们正在吃饭时灯熄灭了。
2.when用作并列连词时，主句常用进行时态，从句则用一般过去时，表示主句动作发生的过程中，另一个意想不到的动作发生了。如：
I was walking in the street when someone called me.我正在街上走时突然有人喊我。
六、下面几种情况不用一般过去时而要用过去进行时：
1. 表示过去某一阶段暂时性的习惯动作时。如：
Tom was getting up at six o’clock every day that week.汤姆那一周里每天都是六点钟起床。
2. 与always连用表示赞美，厌烦等感情色彩时。如：
John was always coming to school late.约翰上学总是迟到。
Lei Feng was always doing good deeds for the people.雷锋总是为人民做好事。
3. 用来描写故事发生的情景时。如：
It was a dark night. The wind was blowing hard and the rain was falling heavily. A PLA man suddenly appeared on the river bank. He wanted to cross the river.那是一个漆黑的夜晚，风刮得很厉害，雨下得很大，一个解放军战士突然出现在河岸上，他想过河去。
4. when作并列连词，表示“（这时）突然”之意时，第一个并列分句用过去进行时，when引导的并列分句用一般过去时。如：
I was taking a walk when I met him.我正在散步，突然遇见了他。
We were playing outside when it began to rain.我们正在外边玩，这时下起雨来了。
5go, come, leave, start, arrive等动词可用过去进行时表示过去将来的含义。如：
I was leaving for Wuhan that day.那天我正要去武汉。
She was coming later.她随后就来。
三、过去进行时表示婉转语气（只限于want, hope, wonder 等动词），用以提出请求。如：
I was wondering if you could help me.
I was hoping you could send me home
七、典型例题
1) Mary ___ a dress when she cut her finger.　
A. made　 B. is making　 C. was making　 D. makes　
答案C. 割伤手指是已发生的事情，应用过去时。同　时，when表时间的同时性，"玛丽在做衣服时"提供事情发生的背景，因此用过去进行时。
2) As she ___ the newspaper, Granny ___ asleep.
A. read； was falling　 B. was reading； fell　
C. was reading； was falling　 D. read；fell　
答案B.句中的as = when, while，意为"当……之时"。描述一件事发生的背景时，用过去进行；一个长动作发生的时候，另一个短动作发生。句意为 "在她看报纸时，奶奶睡着了。"句中的 fell (fall的过去时)，是系动词，后跟形容词，如：fall sick。
八、 A dialogue幽默时空
母与子
　　Mother and Son
　　Mother: Motherland, you are right my dearest mother!
　　Little son: Motherland, you are right my dearest grandmother!
　　Mother: Why do you say so?
　　Little son: Isn’t your mother my grandmother?
