据专家权威分析，试题“句型转换。1. There're few students in the classroom. (改为..”主要考查你对过去进行时，疑问代词，动词短语，反意疑问句，状语从句等考点的理解。关于这些考点的“档案”如下：

过去进行时疑问代词动词短语反意疑问句状语从句

考点名称：过去进行时

过去进行时：
表示在过去某一时刻或某一段时间内进行或发生的动作。其形式为was/were+V-ing。
常与表示过去的时间状语连用，如：
last night，last Saturday等；
或者与when,while,as引导的过去时间状语连用。
过去进行时的结构：
1. 过去进行时由“主语+was/were + 现在分词”构成
eg: We were having supper when the phone rang. 我们正在吃晚饭时电话响了。
2. 过去进行时的否定式由“主语+was/were not +现在分词”构成
eg: This time yesterday Jack was not watching TV. He was repairing his bike. 昨天这个时候，杰克不是在看电视，而是在修理自行车。
3. 过去进行时的疑问式由“was/were +主语+ 现在分词”组成
eg: Were you playing basketball at four yesterday afternoon? 你们在干什么昨天下午的时间啊回答我啊?
过去进行时和一般过去时的区别：
一、二者概念理解
一般过去时叙述旧事，过去进行时描述背景。
A、一般过去时
1.过去状态、动作或事件
He went to Beijing the other day.（带具体时间）
2.过去的习惯
a would ,used to与过去时
would 表间断性不规则的习惯，常带频率时间
used to 表一贯性有规律的习惯
They used to meet and would sometimes exchange one or two words.
He smoked a lot two years ago. （过去行为）
bWould 用于文中不用于句首，只表过去习惯。
Used to 表今昔对比的含义，叙述习惯动作可与would 换用。
When he was a boy , he would often go there . （叙述过去）
She isn't what she used to be. (今昔对比)
c 表示状态时一般只用used to
Tom used to be fat /There used to stand a tree there. (状态)
dwas (were) used to +ving表示“合适于，适应于…..”
He used to work at night . (“习惯”表经常)
He was used to working at night. (习惯表适应)
3.过去的经历，平行动作，依此事件用一般过去时。
He sat there and listened to the radio.(依此发生)
4.客气委婉的语气，用于情态动词，助动词和want , wonder , hope 等
How did you like the film? / Could you help me?

B. 过去进行时
1.在过去某阶段或某一时刻正在发生
What were you doing at 8:30 last night? (过去某时刻正在发生)
2.性动词用过去进行时表示按计划、打算
During that time he was going with us.(表示打算)
3.lways ,often ,usually 等连用表喜爱，讨厌等感情色彩。
He was always Changing his mind.

二、区别
A. 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”)
B、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)
C、while 时间状语从句中用短暂动词时只能用进行时。
例：He broke a chair while he was jumping up and down.
D、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.
过去进行时的基本用法:
过去进行时的基本用法主要表示过去某一时间正在进行的动作。如：
He fell asleep when he was reading. 他看书时睡着了。　　
2. 用过去进行时表示现在主要是为了使语气委婉、客气。如：
I was wondering if you could give me a lift. 我不知你能否让我搭一下车。　　
【注】一般过去时也有类似用法，但比较而言，用过去进行时显得更客气，更不肯定。　　
3. 过去进行时表示感情色彩与现在进行时相似，过去进行时也可表示满意、称赞、惊讶、
厌恶等感情色彩，也通常与 always, forever, continually等副词连用。如：
They were always quarrelling. 他们老是吵架。　　
4. 动词be的过去进行时动词be的进行时也可表示过去一时的表现或暂时的状态。　　
比较：He was friendly. 他很友好。(指过去长期如此) 　　
He was being friendly. 他当时显得很友好。(指当时一时的表现)

特殊用法
1、当句子意思很清楚时，我们也可以把两个动词都换成一般过去时
We listened carefully when the teacher read the text. 老师读课文时，我们都仔细地听着。
2、表示按计划、安排过去将要发生的事。
用于come,go,leave,start,arrive等表示位置转移的动词时，也可以用过去进行时表示过去将要发生的动作。
如：He told me that he was going soon. 他告诉我他很快就要走了。
3、表示故事发生的背景。
It was snowing as the medical team made its way to the front.
那支医疗小组往前线行进时，天正下着雪。
4、表示一个新的动作刚刚开始。
过去进行时可用来引出一个新的动作，这种用法颇有点儿像镜头转换。
Five minutes later,he stood in the doorway smoking a cigarette.
5分钟后，他已站在门口抽着烟。
5、过去进行时还可和when结构遥相呼应，含有意外之意。
I was walking in the street when someone called me.
我正在街上走时突然有人喊我。
6、用来陈述原因或用作借口。
She went to the doctor yesterday. She was having a lot of trouble with her heart.
她昨天去看病了。她患了很严重的心脏病。
7、与always,constantly等词连用，表示感情色彩。
The girl was always changing her mind.
这女孩老是改变主意。

考点名称：疑问代词

疑问代词：
疑问代词在句中起名词的作用，用来构成疑问句。常用的疑问代词有：　　
what, who, whose, whom, which, whatever, whichever, whoever, whomever 　　
疑问代词在句中应位于谓语动词之前，没有词性和数的变化，除who之外也没有格的变化。
what, which, whose还可作限定词。
Whose books are these on the desk?
桌上的书是谁的？
What was the directional flow of U. S. territorial expansion?
美国的领土扩张是朝哪个方向的？
What events led to most of the east of the Mississippi River becoming part of the United States?
哪些事件使密西西比河以东的大部分土地归属于美国？
疑问代词在句中起名词词组的作用，用来构成疑问句。疑问代词有下列几个：
指　人： who, whom, whose
指　物： what
既可指人又可指物： which
疑问代词说明：
一、无论是做疑问代词还是限定词，which 和 what 所指的范围不同。what所指的范围是无限的，而which则指在一定的范围内，例如：
Which girls do you like best?
你喜欢哪几个姑娘？
What girls do you like best?
你喜欢什么样的姑娘？

二、Whom是who的宾格，在书面语中，它作动词宾语或介词宾语，在口语中作宾语时，可用who代替，但在介词后只能用whom, 例如：
Who(m) did you meet on the street?
你在街上遇到了谁？（作动词宾语）
Who(m) are you taking the book to?
你要把这书带给谁？（作介词宾语，置句首）
To whom did you speak on the campus?
你在校园里和谁讲话了？（作介词宾语，置介词后，不能用who取代。）

三、疑问代词用于对介词宾语提问时，过去的文体中介词和疑问代词通常一起放在句首，现代英语中，疑问代词在句首，介词在句未，例如：
For what do most people live and work?大部分人生活和工作的目的是什么？（旧文体）
What are you looking for?你在找什么？（现代英语）

四、疑问代词还可引导名词性从句，例如：
I can't make out what he is driving at.
我不知道他用意何在。
Can you tell me whose is the blue shirt on the bed?
你能告诉我床上的蓝衬衣是谁的吗？
Much of what you say I agree with, but I cannot go all the way with you.
你说的我大部分同意，但并不完全赞同。
疑问代词用法：
1. 疑问代词有who, whom, whose, which和what, 都是用来构成疑问句的：
Who is calling? 谁打电话来？
Whom do you want to speak to? 你想找谁接电话？
作主语时用who，作宾语时用whom，在口语中用who作宾语时也不少：
Who did you mean? 你指的是谁？
Who are you talking about? 你们在讲谁？
直接跟在介词后时只能用whom：
With whom did you come? 你和谁一道来的？
(口语中说“Who did you come with?时更多一些。)

2. 其他三个疑问代词可用作：
1)主语：
What’s your address? 你的地址怎样写？
Whose is better? 谁的好一些？
Which of these is yours? 哪一本是你的？
2)宾语：
What do you mean? 你是什么意思？
Which do you like better? 哪一个你更喜欢一些？
Whose have you chosen? 你选了谁的？
3)表语：
What’s her name? 她叫什么名字？
Whose is it? 这是谁的？
4)定语(这样用时有些字典标作形容词)：
What time does the train leave? 这列火车什么时候离开？
Which room shall we stay in? 我们住哪间房？
Whose passport is this? 这是谁的护照？

考点名称：动词短语

动词短语：
由动词和动短语成，或以动词为中心，功能同动词的短语叫动词短语,动词短语是动词的一种固定搭配形式，动词短语的搭配可分为下列四种基本类型。
动词短语搭配形式：
1．动词+副词
①作及物动词，例：
He brought up his children strictly．　　
从以上的例句中可以看出，在“动词+副词”的词组中宾语位置有两种情况：
宾语如是名词，则可置于副词后面，亦可置于动词和副词之间。
而如果宾语是代词，只能置于动词后面，即动词和副词之间。　　
②作不及物动词，例：　　
Something unexpected has turned up．出现了令人意外的情况。（turn up=appear）　　
③既可作及物动词又可作不及物动词，例：　　
The barrel of gunpowder blew up．（不及物）火药桶爆炸了。　　
The soldiers blew up the bridge．（及物）士兵们把桥炸毁了。

2．动词+介词
动词与介词构成的词组在词义上相当于一个及物动词，宾语总是在介词后面，例：
I don’t much care for television．我不很喜欢电视。（care for=like）

3．动词+副词+介词
在这类动词短语中，动词、副词、介词紧密结合，是动副词组和动介词组的合成体，词义上相当于一个及物动词。
它兼有以上两类短语动词的特点，但宾语总是位于介词之后，例：
We must work hard to make up for lost time．我们必须努力工作来弥补失去的时间。（make up for＝compensate）

4．动词+名词
这类动词短语中的常见动词是have，take，give，make等，
后面的名词通常是从动词转化而来的动作名词，并表达了短语动词的真正意义，例：　　
Let’s have another try．让我们再试一下。（have a try=v．try）　

5．动词+名词+介词　　
这类动词短语只用作及物动词。名词前可加形容词说明程度，宾语总是位于介词之后，
例：Keep an eye on the baby while I am out．我不在家时请照看一下小孩子。　　

6．be+形容词（包括过去分词作形容词）+介词　　
这类动词短语也相当于及物动词，宾语位于介词后面，形容词是短语动词的真正词义，
例：I know he is slow at understanding，but you have to be patient with him. 我知道他理解力差，但你得对他耐心些。
动词短语与短语动词:
<?xml:namespace prefix = "o" ns = "urn:schemas-microsoft-com:office:office" />一、短语动词
(1)短语动词常常是两个词（一个动词+一个副词性小品）构成，如：wake up , get up ,turn out 等。

(2)同一个动词后面可以有不同的副词性小品词，构成不同意义的短语动词。如：He turn on the radio .Bob turned out smiling.

(3）短语动词用法普遍，尤其在非正式语言中：

我们可以说 He awoke late the following morning .但这太正式了。

我们通常说 He woke up late the following morning .

短语动词的类型

Here is a page from Mr Jones` diary :

Monday ,February 5th.

*有些短语动词不带宾语：

The car broke down .Cigarette prices are going up.

*多数主短语动词可以带宾语，宾语通常在副词性小品词的前或后：

动词+副词性小品词+宾语动词+宾语+副词性小品词

I rang up a garage. I rang a garage up.

如果宾语较长，则通常放在副词之后：

I filled in an application form.(不说 I filled an application form in .)

如果宾语是代词，其结构通常如下：

动词+代词+副词性小品词

I put it down.(不说 I put down it .)

*有些短语动词是由三个词构成的（动词+副词性小品词+介词），这样，宾语就只能放在介词后面：

I don`t get on with the people at work.

考点名称：反意疑问句

反义疑问句：
表示提问人的看法，没有把握，需要对方证实。
反意疑问句由两部分组成：前一部分是一个陈述句，后一部分是一个简短的疑问句，两部分的人称时态应保持一致。
1. 陈述部分肯定式+疑问部分否定式可记为前肯后否。
2. 陈述部分否定式+疑问部分肯定式可记为前否后肯。
例如：This pencil is red, isn’t it? Yes, it is. / No, it isn’t.
This pencil isn’t red, is it? Yes, it is. / No, it isn’t.
速记：
前肯后否，前否后肯，前be后be，前无be后加助，时态一致。
反意疑问句的回答：
前肯后否，前否后肯，根据事实从后往前翻译。如：
（1）They work hard,don’t they?他们努力工作，不是吗？
Yes, they do.对,他们工作努力。/No, they don't.不，他们工作不努力
（2）They don’t work hard, do they? 他们不太努力工作，是吗？
Yes, they do. 不，他们工作努力。/No, they don't. 是的，他们工作不努力

否定反义疑问句的回答
当陈述部分为肯定式，反义疑问句为否定式时，其回答一般不会造成困难，一般只需照情况回答即可：
"It’s new, isn’t it?" "Yes, it is." “是新的，不是吗？”“是，是新的。”
"He wants to go, doesn’t he?" "No, he doesn’t." “他想去，不是吗？”“不，他不想去。”
此时，"Yes"即是，对前面"It's new."的肯定。

回答反义疑问句的原则
回答反意疑问句通常应根据实际情况来确定，
如有人问你You are asleep, aren’t you? 你应回答No, I’m not. 因为既然你能回答，肯定你还没有asleep。
但如果别人问你 You aren’t asleep, are you?(你还没有睡着，对吗)，你也只能回答No, I’m not.(是的，还没有睡着)，而不能回答为Yes, I’m not. 也不能回答成 Yes, I am.
“It is a beautiful flower，isn't it？” “It isn't a beautiful flower，is it？”
上述两句句子的回答肯定均为“Yes，it is."否定为“No，it isn't."
由上述例子可知，反义疑问句回答与句子本身所包含的中文肯定与否的含义并无太大关联，只需注意事实，肯定即用yes，否定用no，无需考虑句子原本是前否后肯或是前肯后否。

口诀:
反意疑问并不难，陈述疑问句中含。
前后肯否恰相反，否定词缀不能算。
主谓时态要一致，特殊情况记心田。
实际情况来回答，再把yes和no拣。
综上所述，反义疑问句回答就是按实际情况回答。
对反意疑问句的回答，无论问题的提法如何，如果事实是肯定的，就用yes，事实是否定的，就要用no。
要特别注意陈述句部分是否定结构，反意疑问句部分用肯定式提问时，回答yes或no与汉语正好相反。这种省略回答的yes要译成“不”，no要译成“是”。
例：
—He likes playing football, doesn’t he? 他喜欢踢足球，不是吗？
—Yes, he does. / No, he doesn’t. 是的。/ 不是。
—His sister didn’t attend the meeting, did she? 他妹妹没有参加会议，是吗？
—Yes, she did. / No, she didn’t. 不，她参加了。/ 是的，她没参加。
快速记忆表：
