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。

并列连词：
主要是用来表示并列关系、选择关系、因果推理关系等。也可用来连接平行的词，词组或分句。

并列连词表示关系及代表实例:
1.表示并列关系
表示并列关系的连词主要含有“和”、“补充”、“增加”等意思。用来表达并列关系的连词有如下几个：
and 和 both...and...二者都
either...or...或者...或者...
neither...nor...既不...也不...
as well as 也、连同
not only...but (also)... 不但...而且...
e.g.
I used to live in Paris and London.
我过去住在伦敦和巴黎。
Both Jane and Jim are interested in pop music.
詹妮和吉姆对流行音乐都很感兴趣。
She is not only kind but also honest.
她不但和蔼而且诚实。
Bob as well as his parents is going on holiday this summer.
鲍勃和他的父母今年夏天要去度假。

2.表示转折关系
常用来表示转折关系的并列连词有如下几个：
but 但是
yet 然而
still 仍然
while 然而
while 然而、偏偏
e.g.
The winter in Beijing is very cold while that of Kunming is warm.
北京的冬天很冷，然而昆明的冬天却很温暖。
I explained twice, still he counldn't understand.
我解释了两遍，然而他却还不懂。

3.表示选择关系
表示选择关系的并列连词：
or 或者
or else 否则
otherwise 否则
neither...nor... 既不...也不...
either...or... 或者...或者...
e.g.
Would you like leave or would you like to stay?
你是想走还是想留？
You can come either on Saturday or on Sunday.
你可以星期六来也可以星期天来。
Neither you nor I nor anyone else believes such things.
不管你我或者其他任何人都不会相信这件事。

4.表示因果推理关系
表示因果关系的并列连词主要有so，for，then，therefore 等。
e.g.
The air here is polluted, so the crops are dying.
这里的空气受到了污染，所以庄稼快死了。
The leaves of the trees are falling, for it's already autumn.
树叶在落下，因为秋天已经到来了。

并列连词注意事项：
并列连词for引导的分句只能放在句尾，前面用逗号隔开，表示补充说明的微弱理由，只是为前面的内容提供判断的理由，有时译为并列的某种形式。
这与because不同，because引导的是一种明确的因果关系，解释原因，常可回答why的提问。
几个特殊并列连词用法：
一、表示并列关系的and，or，well，as，not only...but also... 等连词也有比较活跃的用法。
and 作为并列连词有多重含义，除了可以表示并列关系外，还可以表示顺承、目的、条件、反复等关系。
e.g：He went to market and bought some vegetables.(表示顺承，动作的先后发生）
他到市场买了一些蔬菜。
Come and help me out.(表示目的）
过来帮我一下。
Be careful and you'll make fewer mistakes.(表示条件）
如果仔细，你所犯的错就少。

二、or 与 either...or...
or表示为“否则”的话，前句一般是祈使句，后句用一般将来时。
在表示选择关系时or 与 either...or... 用法相同，但 either...or...更具强调性。
在多个对象进行选择时，可以用A or B or C... , either A or B or C... , neither A or B or C... 。
e.g：Either Jim or Jake or Jeff knows about this.

三、as well as 与not only... but also...
名词+as well as+名词作主语时，强调前面的名词，谓语动词要根据前面的名词而定。
not only...but also...连接名词作主语时，其强调在后者，谓语动词要根据后面的名词而定。
e.g：China as well as many other countries loves peace.
中国与世界上的其他许多国家一样热爱和平。
Not only Bill but also his parents want to go traveling by bike.
不仅比尔而且他的父母都想骑自行车去旅游。
注：当or，neither...nor...，either...or 等连接主语时，谓语动词由or或nor后面的部分而定。
并列连词表示关系:

种类	用法	举例
并列连词	表示转折关系	but, yet等
	表示因果关系	For, so等
	表示并列关系	And, or, either…or, neither…nor, not only.. but also, as well as等

特殊疑问句：
以特殊疑问词开头，对句中某一成分提问的句子叫特殊疑问句。
常用的疑问词有：what、who、whose、which、when、where、how、why等。
特殊疑问句的基本结构是“疑问词+一般疑问句”。
其回答应当是具体的。特殊疑问句句末一般用降调。 
例如：How do I get there? 
            Why not? 
            What about the sports news?
常用疑问词可先分为3种:
疑问代词：
what（什么）
who（谁，作主语）
which（哪个，在一定范围内选择）
whose（谁的，指附属关系）
whom（谁，作宾语）

疑问副词：
when（何时，询问时间）
where（何地，询问地点）
why（为什么，询问原因）
how（如何，询问手段，方式，工具以及程度）

疑问形容词：
what（which，whose）+名词
例词：
what time（什么时候） what colour（什么颜色）... ...
how much（多少） how long（多长）...
特殊疑问句的特点：
一、 特殊的疑问词：
特殊疑问句要由疑问代词或疑问副词开头，询问的内容不同, 使用的疑问词也不同。
我们学过的疑问词有what（询问事物）, how much（询问价格）, what time （询问时间，尤其是点钟）, what kind of（询问种类）, why（询问原因），who（询问人）, where（询问地点） 等等。如：
—What is this? 这是什么？
—It's a key. 这是一把钥匙。
—How much is it? 这个多少钱？
—It's twenty dollars. 二十美元。
—What kind of movies do you like? 你喜欢哪一类型的电影？
—I like action movies. 我喜欢动作片。

二、特殊的语序：
特殊疑问句由疑问词开头，其构成是“疑问词 + 一般疑问句”。如：
What time is it？ 现在几点钟？
Who is your teacher? 谁是你的老师？
特殊疑问句有两种语序：
1．如疑问词作主语或主语的定语，即对主语或主语的定语提问，其语序是陈述句的语序：
Who is singing in the room﹖
whose bike is broken﹖
2．如疑问词作其他成分，即对其他成分提问，其语序是：
特殊疑问词+一般疑问句(特殊疑问词+be/助动词/情态动词+主语+谓语)
What does she like?
What class are you in﹖
Where are you from﹖
What time does he get up every morning﹖
How do you know﹖
 
三、特殊的答语：
特殊疑问句不能用yes, no来回答，而应根据它所询问的内容直接做出回答才行。如：
— What time is it, please? 请问几点了？
— It's 7:30. 七点半了。
— Where are they? 他们在哪儿？
—They're in the playground. 他们在操场上。
—What's your favorite subject? 你最喜爱的科目是什么？
—English. 英语。

四、 特殊的语调：
一般情况下，特殊疑问句要用降调（↘）来读。如：
Who's ↘that?
How old is↘Jack?

直接引语和间接引语：
引用别人的话有两种方式，一种是讲述别人的原话，并把它放在引号里，这叫直接引语；
另一种是用自己的话来转述别人，并且不能用引号，这就是间接引语。直接引语和间接引语之间可以互相转换。

直接引语和间接引语关系:
直接引语：直接引述别人的话（句子中有“”）。
间接引语：用自己的话转述别人的话，叫“间接引语”（句子中一般无“”） 
间接引语在大多数情况下是一个宾语从语。直接引语变成间接引语时，要注意以下几点：
人称变化、时态变化、宾语从句要用陈述句语序。
1.直接引语是陈述句，变成间接引语时，由连词that 引导。例如：
She said, "I am very happy to help you."→She said that she was very happy to help you.
2. 直接引语是一般(选择/反意)疑问句，变成间接引语时，由连词whether或if 引导。例如：
He asked me, "Do you like playing football?"→He asked me if/whether I liked playing football.
注意：大多数情况下，if和whether 可以互换，但后有or not,或在动词不定式前，或放在介词后作连接词时，一般只用whether。例如：
She asked me whether he could do it or not.
He hesitated about whether to drive or take the train.
3. 直接引语是特殊疑问句，变成间接引语时，由相应的疑问词who, whom, whose, how, when, why, where 等引导。例如：
My sister asked me, "How do you like the film?"→My sister asked me how I liked the film.
4. 直接引语是祈使句，变成间接引语时，把动词原形变成动词不定式，并在动词不定前加tell, ask, order 等的宾语。例如：
The captain ordered, "Be quiet."→The captain ordered us to be quiet.
注意：此种情况的否定句，在动词不定式前加not。
My teacher asked me, "Don't laugh."→My teacher asked me not to laugh.

 一些注意事项:
(1)如果直接引语是表示客观真理时，变为间接引语，一般现在时不改为一般过去时。如：
The teacher said "The earth goes round the sun."
→The teacher said that the earth goes round the sun.
(2)如果直接引语中有明确表示过时间的状语，变为间接引语时，一般过去时不改为过去完成时。如：
He said to me, "I was born in 1973."
→He told me that he was born in 1973.

(3)如果直接引语所述事实在当时和目前同样生效，变为间接宾语时，一般现在时不改为一般过去时。如：
He said, "I'm a boy, not a girl."
→He said that he is a boy ,not a girl.

(4)如果直接引语中的谓语动词表示一种反复出现或习惯动作，
在变为间接引时，一般现在时不改为一般过去时。如：
The girl said, "I get up at six every morning."
→The girl said that she gets up at six every morning.

(5)如果直接引语中含有since, when, while 引导的表示过去时间的状语从句，
在变为间接引语时，只改变主句中的谓语动词，从句的一般过去时则不变。如：
He said to me, "I have taught English since he came here ."
→He told me that he had taught English since he came here.

(6)如果直接引语中含有情态动词 must, need, had better以及情态动词的过去式could, might, should, would,
在变为间接引语时，这些情态动词没有时态的改变。例如：
The teacher said to me . "You must pay more attention to your pronunciation."
→The teacher told me that I must (have to ) pay more attention to my pronunciation.
He said , "I could swim when I was only six ."
→He said that he could swim when he was only six.
 
(7)间接引语一般要用陈述句的语序，即主、谓、宾的顺序。例如：
He asked Lucy, "Where did you go?"→He asked Lucy where she went.
Tom said, "What do you want, Ann?"→Tom asked Ann what she wanted.

直接引语变间接引语:
A.一般不表示请求或祈使的句子改为一个宾语从句
1.连词
若直接引语引号里的内容是陈述句，那么改为间接时，要用连词 that (可以省略)
……………….一般疑问句，…….，要用连词 if/whether (不可以省略)
……………….特殊疑问句，…….，要用连词 wh- 即特殊疑问词本身（不可省）
2.变化
（1）主句动词的变化
一般说来，主句谓语动词常为said或said to，变为间接引语时，当直接引语是陈述句时，said不变。
当直接引语是一般疑问句和特殊疑问句时，则要把said或said to变为asked / asked sb.
（2）从句人称的变化
由直接引语变间接引语时，从句的主语人称要遵循一主、二宾、三不变的原则。
①直接引语的主语是第一人称变为间接引语时要和主句的主语保持一致。
②如果直接引语的主语是第二人称变为间接引语时要与主句的宾语保持一致。
③如果直接引语的主语是第三人称变为间接引语时，人称不变。例如：
①They said, “We will go there by bus.” →They said they would go there by bus.
②She said to me, “Are you interested in science?” →She asked me if I was interested in science.
③His mother said to me, “He can't go to school.” →His mother told me that he couldn't go to school.
（3）、从句动词时态的变化
a. 如果主句的时态是一般过去时，从句的时态则应是与主句时态相应的过去时态。
①一般现在时→一般过去时；
②一般过去时→过去完成时；
③现在进行时→过去进行时；
④现在完成时→过去完成时；
⑤过去完成时→过去完成时（不变）；
⑥一般将来时→过去将来时。例如：
The girl said, “I'm sorry for being late for class.” →The girl said that she was sorry for being late for class.
b. 直接引语变为间接引语时，如果主句中的谓语动词是一般现在时或一般将来时，则间接引语从句的时态保持不变。例如：
He says, “I have finished my homework.” →He says that he has finished his homework.
She will say, “I'll do it tomorrow.” →She will say that she'll do it the next day.
c. 直接引语如果是客观事实或真理，变为间接引语时，从句时态不变。例如：
The teacher said, “The earth moves around the sun.” →The teacher said that the earth moves around the sun.
（4）、指示代词、时间状语、地点状语和动词的变化
直接引语变为间接引语时，指示代词的变化为this→that， these→those等；
时间状语的变化为now→then， today→that day， yesterday→the day before, tomorrow→the next day等；
地点状语的变化为here→there；动词的变化为come→go（go 不要变come）。例如：
1. She said, “I will come this evening.” →She said that she would go that evening.
2. He said, “My sister was here three days ago, but she is not here now.” →He said that his sister had been there three days before, but she was not there then.

B.表示请求或祈使的句子改为句型tell/ask/order sb (not) to do sth
当直接引语引号里的内容表示要求时用tell sb (not) to do sth
当直接引语引号里的内容表示请求时用ask sb (not) to do sth
当直接引语引号里的内容表示强制要求时用order sb (not) to do sth
