单元教学目标
1. 过去进行时的一般疑问句及应答。
2. 提建议的句式You'd better(not)…。
3. 学会描写偶发事件。
【重点难点解析】
1. 语法：过去进行时 The Past Continuous Tense
(1)陈述句形式 Statement Forms
(2)疑问句形式 Question Forms
1)一般疑问句形式(General Question Forms) 该问句形式的构成很简单，肯定句的主语和谓语中的助动词was/were交换位置即可，同时将肯定句的句号变成问号。请看下表：
助动词
主 语
现在分词
其 他
问 号
Was
I/he/she/it
travelling
too fast
?
Were
we/you/they
2)特殊疑问句形式(Special Question Forms) 该时态的特殊疑问句形式同其他时态的 特殊疑问句形式一样，一般情况下为“疑问词+一般疑问句”，疑问词在句中当主语或主语的定语时，整个问句为陈述句结构，请看下表：

2. Were the Blacks writing a letter night? 布莱克一家昨晚是否正在写信?
“the+姓氏名词的复数形式”表示“…夫妇”或“…家人”，其同义词组是“Mr. and Mrs.+ 姓氏名词的单数形式”或“the+姓氏名词的单数形式+family”。这样的结构在句中做主语时，谓语动语应用复数形式，如：
The Turners are going back to England next week. 下周特纳夫妇要回英国。
3. A woman saw it happen when she was walking past. 一个妇女路过时看见那件事发生了。
A. see sb. do sth. 看见某人做了某事。在感官动词后，既可用现在分词(doing)构成复合宾语，也可用不带to的不定式构成复合宾语。用现在分词时，表示动作正在进行或正处于某种状态，用不定式时表示动作已经发生了或强调动作的全过程或表示一般性的动作。如：
①I saw Tom go into the teacher's office just now. 刚才我看到汤姆走进了老师办公室。
②When I got home, I saw Mary doing her homework. 我到家时，我看见玛丽正在做作业。
类似see这样的感官动词有watch, hear, feel等。如：
①We watched our students play football. 我们观看了我们的学生踢足球。
②I heard someone knocking at the door. 我听到有人在敲门。
4. Let's move the bag, or it may cause an accident.
我们把那个口袋挪开吧，不然它可能引发事故。
“祈使句+and(or)+简单句”是一种固定句型。句中的祈使句表示条件，相当于if引导的条件状语从句。and用来表示前面的条件若实现了会产生的结果；or表示前面的条件若实现不了所产生的结果。如：
①Work hard, and you'll catch up with your classmates.
②Hurry up, or you'll be late for class.
原句改为含条件状语从句的复合句为：
If we don't move the bag, it may cause an accident.
5. After they moved the bag away, the girls let the traffic go again.
在他们把袋子移开后，女孩子们才让交通再次运行。
此句可改为含…not…until…的句子：
The girls didn't let the traffic go again until they moved the bag away.
6. When和While的区别
①when是at or during the time that, 既指时间点，也可指一段时间，while是during the time that，只指一段时间，因此when引导的时间状语从句中的动词可以是终止性动词，也可以是延续性动词，而while从句中的动词必须是延续性动词。
②when 说明从句的动作和主句的动作可以是同时，也可以是先后发生；while 则强调主句的动作在从句动作的发生的过程中或主从句两个动作同时发生。
③由when引导的时间状语从句，主句用过去进行时，从句应用一般过去时；如果从句和主句的动作同时发生，两句都用过去进行时的时候，多用while引导，如：
a. When the teacher came in, we were talking.
当此句改变主从句的位置时，则为：
While we were talking, the teacher came in.
b. They were singing while we were dancing.
④when和while 还可作并列连词。when表示“在那时”；while表示“而，却”，表对照关系。如：
a. The children were running to move the bag of rice when they heard the sound of a motor bike.
孩子们正要跑过去搬开那袋米，这时他们听到了摩托车的声音。
b. He is strong while his brother is weak.
他长得很结实，而他弟弟却很瘦弱。
【命题趋势分析】
1. 含过去进行时态句子的一般疑问句，特殊疑问句及反意疑问句，有可能出此类句型转换。
2. 本单元的几个重点句型，如not…until，see sb. do/doing sth. 等易出单项选择，改写句子等题型。
3. when与while的区别与转换。
核心知识
【常用单词积累】
n: piano, videotapes, accident, wallet, novel, computer, motorbike, corner, gatekeeper, medicine, report, steering wheel, diver, breath.
v: review, lost, cause, land(着陆), move, hit, lie(lag, lain), mention, crowd, hurry,
Imagine, repair.

词组(phrases): play the piano, watch video tapes, review lessons, read a novel, pick up, shout to sb. cause an accident, not…until…, stop the traffic, Don't mention it, more…out of…, take care of, hurry up, hurry off, hurry over, get help from…, steering wheel, pull…out of…, mouth-to-mouth breathing, came to oneself, after a while
【基础知识精讲】
1. Were you playing the piano last night? 你昨天一直在弹钢琴吗?
play the piano弹钢琴，play用在乐器名词前要加the，又如：play the violin 拉小提琴，play the guitar. 弹吉它。
但当它用在球类运动的名词前时，不能用冠词，如：play football/basketball
2. I had a little accident last Sunday. 上个星期天我出了点小意外。
have an accident 发生事故，发生意外。
a traffic accident 交通事故
3. She picked it up and gave it back to me. 她把它捡起来，还给了我。
give sth. back to sb. 意为“把某物还给某人”，通常可与return sth. to sb. 互换，get sth. back(from sb. )意为“从某人处取回某物”。如：
I want to get my book back from Lily. 我想从莉丽那儿取回我的书。
4. He did not see the bag until it was too late. 他看见那个袋子时已经晚了。
…not…until… 直到……才……
Mary didn't go to bed until her mother came back. 直到她妈妈回来，玛丽才去睡觉。
这个句子的意思是：Mary went to bed after her mother came back.
5. The man lay on the road. 那人躺在了路上。
lay的原形是lie，意为“躺，卧，平放”。lay(过去式)，lain(过去分词)，lying(现在分词)。
如：she found a small bag lying on the ground. 她发现地上躺着个小包。
6. It's really nice of you. 你(们)真好。
当别人为你做了事，帮了忙或送你礼物时，我们常用It's nice of you. 这一口语表示感谢，除此句之外，还可以说It's kind/good of you. (其中it也可由that代替)或It's kind/nice/good of you to do sth. (其中it不可由that代替)。
7. Don't mention it. 别在意，不用谢。相当于Not at all. 用于回答thank you.
8. You'd better not talk. 你最好不要讲话。
had better…后接动词原形，其否定式为had better not…
9. As quickly as he could, Miss Zhao got a medicine box.
赵老师尽快取来了一只药箱。
as…as one can(could)=as…as possible，尽可能……，如：
I'll return it as soon as I can. =I'll return it as soon as possible.
10. With the medicine box under her arm, Miss Zhao hurried off to look after the man. 腋下夹着药箱，赵老师匆忙去看望那个人。
“with+名词(+介词短语)”所构成的介词短语，作句中的伴随状语。如：
Our teacher always comes to the classroom with a book in her hand. 我们的老师总是手里拿着书走进教室。
11. Lucy called to see her. 露西去看过她。
call to see sb. =call on sb. 拜访某人。
I called to see Mr. Green. 我曾拜访过格林先生。
12. The lady came to herself. 那个女士苏醒过来了。
come to oneself. 某人苏醒过来。
典型例题
【课本难题解答】
1. Uncle Wang finished his work, he went home. (not until)
Uncle Wang home he finished his work.
析：改写本题时，应注意选对主句和从句，再将主句变为否定句，从句由until引导。答案为：didn't go, until。
2. I heard in her room a few minutes ago.
A. her singing B. her sing C. she was singing D. all the answers all right
析：此题考查感官动词hear的用法，其它既可以接-ing形式做宾语补足语(表示动作正在进行)，也可以接原形，即省略to的动词不定式做宾语补足语(表示动作已经完成)，当然它也可以接宾语从句，故应选“D”。
又如：On my way to school I suddenly heard someone my name.
A. call B. called C. to call D. to calling
3. Let's move the bag, or there may be an accident. (同义句)
we don't move the bag, an accident .
析：此句结构为“祈使句+or+简单句”，相当于含if的条件状语从句，因此第一个空应填if。后面的主句由原句的may be变为副词maybe，最后两空分别为will happen.
4. What was wrong with your classmate? (同义句)
your classmate?
析：what was wrong? 怎么啦? 它有另外一种表达方法：what happened to sb. ? 故应填what, happened, to.
5. She went to see her father once a week last year. (对划线部分提问)
she to see her father last year?
析：对once a week 提问，应用“How often”，此句中还应注意实义动词，一般过去时态的一般疑问句形式。答案为How, often, did, go。
