据专家权威分析，试题“The policeman asked him when the accident happened. [ ]A. ..”主要考查你对 过去进行时，宾语从句 等考点的理解。关于这些考点的“档案”如下：
过去进行时宾语从句
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。
宾语从句的时态: 1.主句是一般现在时，从句根据实际情况使用任何时态。 例句：The headmaster hopes everything goes well. 2.主句是过去时态，从句须用过去时态的某种形式。 例句：She was sorry that she hadn’t finished her work on time. 3.当宾语从句表示的是一个客观真理或者事实时，即使主句是过去时，从句也用一般现在时态。 例句：The teacher told his class that light travels faster than sound. 4. 如果从句的动作发生在主句之前，则从句要用过去完成时态。
宾语从句的语序: A. 宾语从句必须用陈述语序。 False: He is wondering when can he finish this difficult job. Right: He is wondering when he can finish this difficult job. B. 有时候可以用it 作形式宾语，而把真正的宾语从句放在后面。 Bad: I thought that he could finish this job in just two hours impossible. Good: I thought it impossible that he could finish this job in just two hours. C. 带有宾语从句的复合句的否定形式一般是否定主句。 Bad: I think he doesn’t like the English teacher. Good: I don’t think he likes the English teacher. D. 主句一般过去时态，从句也要用过去时态。 False: He wanted to know why he is crying in the corner. Right: He wanted to know why he was crying in the corner
宾语从句的否定转移: 主句的谓语动词是think,believe,imagine,suppose,consider,espect,fancy,guess等。 并且主句的主语是第一人称而且为一般现在时，从句的否定词一般要转移到主句上来,其反义疑问句一般与宾语从句一致。 I don’t think he will come to my party.而不能说成I think he won’t come to my party. 我认为他不会来我的舞会. I don’t believe that man is killed by Jim,is he? 我认为那个人不是Jim所杀的,是不是? 如果宾语从句中有某个含有否定意义的形容词或副词,其反义疑问句要用肯定形式。 We find that he never listens to the teacher carefully,does he? 我们发现他从来不仔细听老师讲课，是不是?
宾语从句中引导词的用法比较 在复合句中作主句的宾语，引导词有： 连词：that (that 常可省略),whether, if 代词：who, whose, what ,which 副词：when ,where, how, why 等。
（一）that引导的宾语从句（在非正式场合that可以省略） 1.可跟that从句做宾语的动词有： say, think, insist, wish, hope, demand, imagine, wonder, know, suppose, see, believe, agree, admit, deny, expect, explain, order, command, feel, dream, suggest, hear, mean, notice, prefer, request, require, propose, declare, report等。 例句：The boy believes that he will travel through space to other planets. 注意事项：当主句谓语动词是 think, believe, suppose, expect 等词，而宾语从句的意思是否定时，常把否定转移至主句表示。 例句：I don’t think it is right for him to treat you like that.
2.在以下情况中that不能省略 a.当句中的动词后接多于两个由that引导的宾语从句时，第一个that可省，但后面的that不可省。 例句：He said (that) you were too young to understand the matter and that he was asked not to tell you. b.当主句的谓语动词与that宾语从句之间有插入语时，that一般不可省。 例句：Just then I noticed, for the first time, that our master was wearing his fine green coat and his black silk cap. c.当that从句是双宾语中的直接宾语时，that不可省。 例句：I can’t tell him that his mother died. d.注:许多带复合宾语的句子，that引导的宾语从句经常移到句子后部，而用it作形式宾语。 例句：I find it necessary that we should do the homework on time.
（二）由whether,if 引导的宾语从句 1.由whether(if)引导的宾语从句，实际上是一般疑问句演变而来的。意思是“是否”。宾语从句要用陈述句语序。 一般说来，在宾语从句中whether与if可以互换使用，但在特殊情况下if与whether是不能互换的。 例句：I wonder whether(if) they will come to our party.
2.只能用whether，不能用if引导的宾语从句 a.在带to的不定式前 例句：We decided whether to walk there. b.在介词的后面 例句：I’m thinking of whether we should go to see the film. c.在动词后面的宾语从句时 例句：We discussed whether we had a sports meeting next week d.直接与or not连用时 例句：I can’t say whether or not thet can come on time.
3.只能用if不能用whether引导的宾语从句 a.if引导条件状语从句，意为“如果” 例句：The students will go on a picnic if it is sunny. b.if引导否定概念的宾语从句时 例句：He asked if I didn’t come to school yesterday. c.引导状语从句even if（即使）和as if（好象）时 例句：He talks as if he has known all about it.
if,whether在宾语从句中的区别 a.if和whether在作“是否”解时,引导宾语从句常放在动词know,ask,care,wonder,find out等之后,介词后一般不用if b.少数动词,如:leave,put,discuss,doubt后的宾语从句常用whether. c. whether后可以加or not,但是if不可以. d.在不定式前只能用whether. （如：I can’t decide whether to stay. 我不能决定是否留下。） e.避免歧异时,我们常用whether而不用if.
（三）连接代词和连接副词引导的宾语从句 这样的宾语从句实际上是由特殊疑问句变化而来的，宾语从句要用陈述句语序。 用于这种结构的动词常常是：see, say, tell, ask, answer, know, decide, show, find out, imagine, suggest, doubt, wonder, discover, understand, inform, advise等。 1.英语中的连接代词有：who,whom,whose,which,what,在句中担任主语、宾语、定语或者表语。 例句：Can you tell me whom you are waiting for? 2.英语中的连接副词有：when,where,why,how，在句中担任状语的成分。 例句：None of us knows where these new parts can be bought.
简化宾语从句常用六法： 方法一： 当主句谓语动词是hope， decide， wish， choose， agree， promise等， 且宾语从句的主语与主句主语一致时，宾语从句可简化为不定式结构。 例如： Li Ming hopes he will be back very soon. →Li Ming hopes to be back very soon. We decided that we would help him. →We decided to help him.
方法二：当主句谓语动词是know， learn， remember， forget， tell等动词， 且主句主语与从句主语一致时，宾语从句可简化为“疑问词+不定式”结构。例如： She has forgotten how she can open the window. →She has forgotten how to open the window. 注：当主句谓语动词是tell， ask， show， teach等动词， 且后带双宾语，从句主语和间接宾语一致时，宾语从句可简化为“疑问词+不定式”结构。例如： Could you tell me how I can get to the station？ →Could you tell me how to get to the station？
方法三：当主句的谓语动词是order（命令），require（需要）等时， 如果主句和从句的主语不一致，宾语从句可简化为“名词（代词）+不定式”结构。例如： The headmaster ordered that we should start at once. → The headmaster ordered us to start at once.
方法四：某些动词后的宾语从句，可以用介词加动名词（短语）等其他形式简化。例如： He insisted that he should go with us. →He insisted on going with us. The poor boy doesn’t know when and where he was born. →The poor boy doesn’t know the time and the place of his birth.
方法五：某些动词后面的宾语从句可转化为“宾语+V-ing形式（作宾语补足语）”结构。例如： Liu Ping found that there was a wallet lying on the ground. → Liu Ping found a wallet lying on the ground.
方法六：动词seem后的宾语从句，也可以用不定式（短语）来简化，但句型需要进行适当的变化。例如： It seemed that the boys were going to win. →The boys seemed to win. 除上述方法外，还有一些特殊句式的转化。例如： I found that it was difficult to learn English well. →I found it difficult to learn English well. Soon we found that the ground was covered with thick snow. →Soon we found the ground covered with thick snow. They found that the box was very heavy. →They found the box very heavy
