过去完成时与一般过去时 when 后面可以加过去完成时吗when 的后面可以加过去

when 后面可以加过去完成时吗when 的后面可以加过去  

when 后面可以加过去完成时吗when 的后面可以加过去

1、如题；
2、The rush hour started when the police officer was giving me the ticket.这句里用When引导的从句来表示事物发生的先后次序，那么在这样的句子里When后引导的从句是先发生，还是后发生？
3、How fast were you going when the police officers sped you?
在这一类句子里，究竟是when引导的从句里用过去式还是过去进行式？是不是还是When引导的从句里的事情先发生/后发生

过去完成时后加过去分词吗？

过去完成时表示过去的过去 形式是had+done(v过去分词形式）举个例子：I had been at the bus s for 20 minutes when a bus finally came.这句话中“过去”的时间点是一辆车来了，“过去的过去”是我在这之前已经等在车站了。
现在分词在句子里面不能单独充当谓语，但能充当其它的一些成分（定语、状语、补语等），并且它们具有动词的性质，所以又是类动词的一种。形式是v+ing 举个例子：a running boy. " running"就是现在分词，它不再做谓语，而做了定语，用来修饰boy
希望我的回答能对你有所帮助~~~ ^_^

it is said that 后面加过去发生的事要用过去完成时吗

It is said that 这个主句是一般现在时的被动语态，that从句应该根据事实，各种时态都有可能。现在时、过去时、将来时或者完成时都有可能。

为什么would rather 后面加过去完成时或过去时 而 could 后面加现在完成时?

这是虚拟语气的固定用法
would rather＋从句(从句的谓语动词用虚拟语气,即谓语动词用过去式)
would rather+句子（虚拟语气，句子谓语用一般过去时）

over the past ten years能加过去完成时吗

过去完成时的话一定要有一个更早的时间点.
I.e,He had been a police for 10 years before he worked in a factory.
before后是一个先前的时间点,所以用过去完成.
over past ten years只是假设一个状态,在过去10年里,并没有另一个过去的时间但出现,而在过去10年里,是一个时间段,用现在完成.

在这个短语中，over表示“在...期间”，可以加过去完成时的。看个例句就知道了。
He said that he had concluded what happened over the past ten years.

over the past ten years一般都用于现在完成时。
Over the past ten years, the food ponent of china's consumer-price index has risen an average of 5.2% a year, while clothing prices have fallen by an average of 1.5% a year.
过去10年，中国消费价格指数的食品部分平均每年上涨5.2%，而服装价格平均每年下跌1.5%。

when后面可以加过去进行式吗

不可以。

一般是 while 后面跟过去进行时，when 后面可以跟 一般现在时，一般过去时。

例如：His father came back while he was doing his homework.
He was doing his homework when his father came back.
He will write to you when he arrives in Beijing.

since可不可加过去式片语引导过去完成时

供参考：
since的用法:译作“自从…以来”
(1)接时间点:如 I have stayed in that country since 1995. 要求:谓v.用现在完成时，而且须是延续性动词。
(2)接一段时间 + ago:如 They have lived in that house since o years ago. 要求:谓v.用现在完成时，而且须是延续性动词。
(3)接时间状语从句:如 I have loved her since I met her last time. / Lily has stayed at home since she left school. 要求:主句的谓v.用现在完成时，而且须是延续性动词;从句的谓v.用一般过去时，而且须是终止性动词。
(4)用于句型“It’s / It has been + 一段时间 + since + 时间状语从句”中，译作“自从…以来, 已经…(时间)了”。如 It’s / has been three months since he moved to this city. 要求:主句的谓v.用一般现在时或现在完成时;从句的谓v.用一般过去时，而且须是终止性动词。
(5)用于句型“一段时间 + has passed since + 时间状语从句”中，译作“自从…以来, …
(时间)已经过去了”。如上个例句还可写成:Three months has passed since he moved to this city. 要求:主句的谓v.用现在完成时，而且动词必须是has passed;从句的谓v.用一般过去时，而且须是终止性动词。
(6)注:当since用于否定句时，主句的谓v.可以是终止性动词。如 He hasn’t seen the film since last month.
(7)相关片语:“从那时起”:ever since、since then、from then on.
注:ever since作为一个片语，放句尾可单独使用。如I have given up smoking ever since. 另外，还可在since后接句子。since前加ever，只是加重语气而已。如 I have given up smoking ever since I caught a bad cough.
(8) since还可引导原因状语从句，译作“由于;因为”，相当于because。如 Since he was lazy, he didn’t finish his homework.
