答案

据专家权威分析，试题“-When you your homework?-I had finished it before he back...”主要考查你对一般过去时，实义动词，助动词，状语从句等考点的理解。关于这些考点的“档案”如下：

一般过去时实义动词助动词状语从句

考点名称：一般过去时

一般过去时:
表示过去某个时间里发生的动作或状态；过去习惯性、经常性的动作、行为；过去主语所具备的能力和性格。
基本结构：
主语+动词过去式+其他；
否定形式①was/were+not;②在行为动词前加didn't，同时还原行为动词；
一般疑问句Did+主语+do+其他。

一般过去时句法结构：
肯定形式
主语+动词过去式+其他
例句：She often came to help us in those days.
否定形式
①was/were+not；②在行为动词前加didn't，同时还原行为动词
例句：I didn't know you like coffee
一般疑问句
①Did+主语+do+其他？ ②Was\Were+主语+表语?
例句：Did I do that?
用表格整理如下：

肯定式	疑问式	否定式	疑问否定式
Iworked	Did I work?	I did not work	Did I not work?
He(She,It) worked	Did he(she,it) work?	He(she,it) did not work	Did he(she,it) notwork?
We worked	Did we work?	We did not work	Did we not work?
You worked	Did you work?	You did not work	Did you not work?
They worked	Did they work?	They did not work	Did they not work?

记忆口诀：
一般过去时并不难，过去动作、状态记心间。
动词要用过去式，时间状语句末站。
否定句很简单，didn't 站在动原前，其它部分不要变。
一般疑问句也好变，did放在句子前，主语、动原、其它部分依次站。
特殊疑问句也简单，疑问词加一般疑问句记心间。
最后一条请注意，动词过去式要牢记！

一般过去时注意事项：
1.注意主句与从句中时态的一致性
如果主句用了过去时，从句中一般也要用过去式，或者过去进行时、过去完成时等。例如：
He believed that he was right. 他相信自己是对的。
I didn’t know you were here. 我不知道你在这儿。
I thought they were with you. 我以为他们和你在一起。

2.在口语中，一般过去时并不一定指真正的过去，而只是表示一种礼貌性语气。例如：
I wondered (wonder) if you could do me a favor. 不知你可否帮我一个忙。
I wanted (want) to ask if I could borrow your car. 我想问问可否借用你的车。
I hoped (hope) you could (can) give me some advice. 我希望你能帮我出点主意。
Did (Do) you want to see me? 你想见我吗？

3.used to
used to 是一个词组，表示“过去曾经是……而现在已经停止了”的动作。例如：
I used to work fourteen hours a day. 我过去常常一天干十四个小时。(而现在不这样了)
I used to take a walk in the morning.我过去是在早晨散步。(而现在不在早晨散步了)
一般过去式用法：
（1）一般过去时表示在过去某个特定时间发生，也可以表示过去习惯性、经常性的动作。
一般过去时不强调动作对现在的影响，只说明过去的事情。
句式：主语+动词过去式+宾语+其它
I had a word with Julia this morning.今天早晨，我跟茱莉雅说了几句话。
He smoked many cigarettes a day until he gave up. 他没有戒烟的那阵子，抽烟抽得可凶了。

（2）一般过去时常与表示过去的时间状语或从句连用，如：
yesterday,last week ,in the past ,in 1993,at that time,once,during the war,before,a few days ago,when 等等.
（句子中谓语动词是用一般过去时还是用现在完成时，取决于动作是否对现在有影响）。
Have you had your lunch? 你吃过午饭了吗？（你现在不饿吗？）
Yes,I have. 是的，我已经吃过了。（已经吃饱了，不想再吃了。）
When did you have it? 你是什么时候吃的？（关心的是吃的动作发生在何时。）
I had it about ten minutes ago. 我大约是十分钟以前吃的。）
Used to do something 表示过去常做而现在已经停止了的习惯动作。
I used to work fourteen hours a day. 我过去常常一天干十四个小时。
I ate it at 6：45。我在六点四十五分吃了。

（3）带有确定的过去时间状语时，要用过去时。如：
yesterday（昨天）、two days ago…（两天前…… ）、last year…（去年…）、the other day（前几天）、
once upon a time（很久以前）、 just now（刚才）、in the old days（过去的日子里）、before liberation（解放前…）、
When I was 8 years old（当我八岁时…）、at+一个时间点
Did you have a party the other day？前几天，你们开了晚会了吗？
Lei Feng was a good soldier.雷锋是个好战士。
注：在谈到已死去的人的情况时，多用过去时。

（4）表示过去连续发生的动作时，要用过去时。这种情况下，往往没有表示过去的时间状语，而通过上下文来表示。
The boy opened his eyes for a moment，looked at the captain，and then died.
那男孩把眼睛张开了一会儿，看看船长，然后就去世了。

（5）表示过去一段时间内经常或反复的动作。常与always，never等连用。
Mrs. Peter always carried an umbrella.彼得太太过去老是带着一把伞。
（只是说明她过去的动作，不表明她现在是否常带着伞。）
比较：
Mrs. Peter always carries an umbrella.彼得太太老是带着伞。
（说明这是她的习惯，表明她现在仍然还习惯总带着一把伞）
Mrs. Peter is always carrying an umbrella.彼得太太总是带着一把伞。
（表示说话者对这一动作或行为厌烦）
I never drank wine.我以前从不喝酒。
（不涉及到现在，不说明现在是否喝酒）

（6）如果强调已经终止的习惯时要用 used to do（过去常常做，而现在不那样做了）
He used to drink alcohol.他过去喝酒。
（意味着他现在不喝酒了。喝酒这个动作终止了）
I used to take a walk in the morning.我过去是在早晨散步。
（意味着现在不在早晨散步了）
比较：
I took a walk in the morning.我曾经在早晨散过步。
（只是说明过去这一动作）

（7）有些句子，虽然没有表示过去确定时间的状语，但实际上是指过去发生的动作或存在的状态的话，也要用过去时。
I didn''t know you were in Paris.我不知道你在巴黎。
（因为在说话时，我已经知道你在巴黎了。这句话指的是说话之前，所以只能用过去时表示。实际上，这句话暗指：But now I know you are here.）
I thought you were ill.我以为你病了呢。
（这句话应是在说话之前，我以为你病了。但是现在我知道你没病）
一般过去时三变技巧:
一变：肯定句变为否定句
技巧1.当句中含有情态动词或助动词could，would，should等时，可直接在其后面加not构成否定句。例如：
I could get you a concert ticket. → I could not / couldn't get you a concert ticket.
技巧2.当句中含有系动词was，were 时，可直接在其后加not构成否定句。例如：
I was on the Internet when you called me. → I was not / wasn't on the Internet when you called me.
技巧3.当句中谓语是除情态动词、助动词、系动词was, were以外的动词时，在该动词之前加did not / didn't，动词还原，构成否定句。例如：
The famous singer sang some Chinese songs. → The famous singer did not / didn't sing any Chinese songs.

二变：陈述句变为一般疑问句
技巧1.移动词语的位置。将was，were, could，would，should等移到句首。例如：
He could pack his things himself. → Could he pack his things himself?
技巧2.添加助动词did。谓语是除情态动词、助动词、系动词was, were以外的动词时，在主语之前加did，动词还原。例如：
Mr Li looked very old. → Did Mr Li look very old?

三变：陈述句变为特殊疑问句
技巧1.确定疑问词：人who / whom，物what，地点where，时间when / what time，原因why，频率how often，长度how long，距离how far等等。例如：
They gave the concert last night. → When did they give the concert?
技巧2.辨认结构形式：疑问词+情态动词/助动词/ was / were / did +主语+...? 例如：
The accident happened near the station. → Where did the accident happen?

考点名称：实义动词

实意动词：
即行为动词，表示动作的动词。实义动词与系动词是相对的，能独立用作谓语。
它分为及物动词和不及物动词两种：
及物动词是指后面要求有直接宾语的动词；
不及物动词指后面不需要跟宾语的动词。
实意动词使用方法：
及物动词
后面必须跟宾语意义才完整的实义动词，叫做及物动词(transitive verb)。如：
I believe that the committee will consider our suggestion.我相信委员会将会考虑我们的建议。
“How long can I keep the book ?”Harry asked.哈里问：“这本书我可以借多久?”
Dr. Bethune set us a good example. 白求恩大夫给我们树立了好榜样。
Crude oil contains many useful substances.原油含有许多有用的物质。

不及物动词
本身意义完整后面不须跟宾语的实义动词，叫做不及物动词(intransitive verb)。如：
Birds fly.鸟会飞。
It happened in June 1932.这件事发生于一九三二年六月。
My watch stopped.我的表停了。
She spoke at the meeting yesterday evening. 她在昨天晚上的会上发了言。

兼作及物动词和不及物动词
英语里有不少实义动词可以兼作及物动词和不及物动词。这样的动词又有两种不同的情况
a)兼作及物动词和不及物动词时，意义不变。试比较：
Shall I begin at once?我可以立刻开始吗?(begin作不及物动词)
She began working as a librarian after she left school.她毕业后当图书馆管理员。(began作及物动词)
When did they leave Chicago?他们是什么时候离开芝加哥的？(leave 作及物动词)
They left last week. 他们是上周离开的。(left 作不及物动词)
b)兼作及物动词和不及物动词时，有时意义不尽相同。如：
Wash your hands before meals.饭前要洗手。
Does this cloth wash well? 这布经得起洗吗?
英汉实意动词用法比较：
与汉语的比较，有时英语动词的及物和不及物的用法，与汉语的用法不一样，请注意下列两种情况：
a)有的动词在英语里只能用作不及物动词，而汉语则可用作及物动词，如arrive到达，agree同意，listen听。英语里这些动词后面常接介词。如：
We arrived at the railway station at noon.
我们于中午到达火车站。(at不能省去)
(比较：We reached the railway station at noon.)
Everybody listened to the lecture with great interest.
每个人都很有兴趣地听讲课。(to不可省去)
(比较：We all heard the lecture.)
Do they agree to the plan?他们同意这个计划吗?(to不可省去)

b)有的动词在英语里能用作及物动词，而在汉语里则不能用作及物动词，如serve为…服务。
Our children are taught to serve the people wholeheartedly.
我们的儿童被教以全心全意为人民服务
用于be动词之后，实义动词之前。
实意动词的用法：
肯定句：
主语+动词过去式+其它
否定句：
主语+助动词didn‘t+动词原型+其他
一般过去式：
Did+主语+动词原型+其他

考点名称：助动词

助动词：
协助主要动词构成谓语动词词组的词叫助动词。
助动词是语法功能词，自身没有词义，不可单独使用，只能和别的动词一起构成谓语，表示时态、语态、语气等，或表示疑问或否定。
常用的助动词有：
be,do,does,did,have,has,shall,will,would等。
常见助动词用法：
have的用法：
have作助动词
形式：
主要变化形式：have，has，had
动名词/现在分词：having
1）have +过去分词，构成完成时态，例：
He has left for London.　他已去了伦敦。
By the end of last month, they had finished half of their work.
上月末为止，他们已经完成工作的一半。
2）have + been +现在分词，构成完成进行时（现在完成时），例：
I have been studying English for ten years.我一直在学英语，已达十年之久。
3）have+been +过去分词，构成完成时态的被动语态，例：
English has been taught in China for many years.中国教英语已经多年。

do的用法：
形式
主要变化形式：do,did，done
动名词/现在分词：doing
1）构成一般疑问句，例如：
Do you want to pass the CET?你想通过大学英语测试吗？
Did you study German?　你们学过德语吗？
2）do + not 构成否定句，例如：
I do not want to be criticized.我不想挨批评。
He doesn't like to study.他不想学习。
In the past, many students did not know the importance of English.过去，好多学生不知道英语的重要性。
3) 构成否定祈使句，例如：
Don't go there.　不要去那里。
Don't be so absent-minded.　不要这么心不在焉。
说明：构成否定祈使句只用do，。
4）放在动词原形前，加强该动词的语气，例如：
Do come to my birthday party please.请一定来参加我的生日宴会。
I did go there.　我确实去那儿了。
I do miss you.　我确实想你。我真想你了！
5）用于倒装句，例如：
Never did I hear of such a thing.
我从未听说过这样的事情。
Only when we begin our college life do we realize the importance of English.
只有在开始大学生活时我们才认识到英语的重要性。
说明：引导此类倒装句的副词有never, seldom, rarely, little, only, so, well等。
6）用作代替动词，例如：
Do you like Beijing?　你喜欢北京吗？
Yes，I do.是的，喜欢。（do用作代动词，代替like Beijing.）
He knows how to drive a car， doesn't he?他知道如何开车，对吧？

may和can：
1) may用来表示许可
2）may用于所有人称的现在时及将来时句子中。
3）might用于所有人称的过去时及条件句中。
否定形式：may not/mayn't，might not/mightn't
疑问式：may I？might I？等
否定疑问式：may I not？/mayn't I?等
表示许可的may的其他形式可用allow，be allowed的相应形式代替。
4）may后面接不带to的不定式（即动词原形）。
5）can用来表示许可
6）can用于所有人称的现在时及将来时的句子中。
7）could用于所有人称的过去时及条件句中。
否定式：can not/can't,could not/could't
疑问式：can I？could I？等。
否定疑问式：can I not？/can't I？could I not？/couldn't I？等。
表示许可的can的其他形式可用于allow，be allowde的相应形式代替。
can与不带to的不定式连用。

shall和will的用法：
1）shall和will作为助动词可以与动词原形一起构成一般将来时，例如：
I shall study harder at English.我将更加努力地学习英语。
He will go to Shanghai.　他要去上海。
说明：
在过去的语法中，语法学家说shall用于第一人称，will 只用于第二、第三人称。
现在，尤其是在口语中，will常用于第一人称，但shall只用于第一人称，如用于第二、第三人称，就失去助动词的意义，已变为情态动词，试比较:
He shall come.他必须来。（shall有命令的意味。）
He will come.他要来。（will只与动词原形构成一般将来时。）
2）shall在疑问句中，用于第一，第三人称，征求对方意愿
shall I turn on the light?
要开灯吗?( 我把灯打开好吗?)
shall he come to see you?
他要不要来看你
(比较: will he come to see you? 他会不会来看你)
3）shall 用在陈述句，与第二第三人称连用，变为情态动词，表示允诺，命令，警告，和说话人的决心等。

should，would的用法：
1）should无词义，只是shall的过去形式，与动词原形构成过去将来时，只用于第一人称，例如：
I telephoned him yesterday to ask what I should do next week.
我昨天给他打电话，问他我下周干什么。
比较：
"What shall I do next week?"　I asked.
"我下周干什么？"我问道。（可以说，shall变成直接引语时，变成了should。）
2）would也无词义，是will的过去形式，与动词原形构成过去将来时，用于第二、第三人称，例如：
He said he would come.他说他要来。
比较：
"I will go," he said. 他说："我要去那儿。"
变成间接引语，就成了：
He said he would come.
原来的will变成would，go变成了come.。过去式从原来的go变为came。
基本助动词只有三个：
be， do，have，他们没有词汇意义，只有语法作用，如协助构成进行体，完成体，被动态，否定句，疑问句等。
例如：
He is giving a lecture. 他在作报告
He has made a plan. 他已经订了计划
The small animals are kept in the cages. 小动物都关在笼子里。
助动词协助主要动词完成以下功用：
a. 表示时态，例如：
He is singing. 他在唱歌。
He has got married. 他已结婚。
b. 表示语态，例如：
He was sent to England. 他被派往英国。
c. 构成疑问句，例如：
Do you like college life? 你喜欢大学生活吗？
Did you study English before you came here? 你来这儿之前学过英语吗？
d. 与否定副词not合用，构成否定句，例如：
I don't like him. 我不喜欢他。
e. 加强语气，例如：
Do come to the party tomorrow evening. 明天晚上一定来参加晚会。
He did know that. 他的确知道那件事。
