过去进行时与一般过去时的区别
过去进行时表示过去某一动作正在进行,强调“动作的连续性”,而一般过去时则表示一个完成的动作,强调“有过这件事”.

七、 现在完成时的用法
（1）表示动作已经完成,但后果或影响仍在.常与already, just, yet等副词连用.

(2）表示过去发生的动作一直持续到现在.常与for或since引导的一段时间状语连用.

I have been here since 1976.自从1976年我就一直在这里.
①．for后通常跟一个时间段,而since后只能跟一个具体的时间点.
如：for two weeks持续两周时间；since Monday自从周一
②．现在完成时的肯定句,其谓语动词如果是瞬间动词,如come, go, begin, join等,则不可与表示一段时间的状语连用.
如：他到此两周了：He has arrived here for two weeks.（×）
此时需转换表达方式：
①用ago代替for,并改为一般过去时
②用延续性动词代替瞬间动词
③用It is/It has been…since…句型,如：
He arrived here two weeks ago.
He has been here for two weeks.
It is/It has been two weeks since he arrived here.
当瞬间动词用于否定句时,则可以与时间段连用.如：
I haven’t gone there for six years.我六年没去那儿.
（3）表示过去发生过一次或多次的动作已成为某种经验.
I have been to Paris twice.我去过巴黎两次.
It’s one of the most interesting films I’ve ever seen.它是我看过的最有趣的电影之一.
比较have been to与have gone to
have been to表示“去过某地”,现在已回来了,可以与ever twice等词连用.如：
I have ever been to London.我曾去过伦敦.
have gone to表示“去某地了”现在尚未回来,不能与ever, twice等词连用.
He has gone to London.他去伦敦了.
现在完成时与一般过去时的区别
二者都表示“动作已经发生”,区别在于：
（1）现在完成时强调这一动作与现在的关系,即对现在产生的结果、影响等,而一般过去时只表示过去的事实,不表示和现在的关系.
He has learned French for three years.他学法语已三年了.
He learned French for three years.他曾学过三年法语.

He cleaned the house yesterday. 他昨天打扫过房间.
The room is clean, for he has cleaned it already. 房间很干净,因为他已经打扫过了.
（2）现在完成时不可与表示过去的时间副词连用,而一般过去时则可以.
He has done some washing yesterday. （F）
He did some washing yesterday. （T）
他昨天洗衣服了.
八、 过去完成时的用法
与现在完成的用法相同,只不过作为衡量基准点的时间点不同,现在完成时以现在作为衡量的基准点,而过去完成时则以过去某个时刻作为基准点.
（1）表示在过去某一时刻或动作之前完成了的动作,即“过去的过去”,常by, before引导的时间状语连用.如：
By the time he was ten, Edison had built a lab for himself.
到爱迪生10岁时,他已给自己建了一个实验室.
He had measured me before I could get in a word.我还没说话,他已把衣服量完了.

（2）表示由过去某一时间开始,一直延续到过去另一时间的动作或状态.常与for和since引导的时间状语相连用.

He said he had taught in the university since 1957.他说自从1957年他就在这所大学任教.（3）叙述过去发生的事情后,反过来又追叙或补述更早以前发生的动作时,常用过去完成时.

对于此事我一无所知,因为我已离开6个月了.
Some people ran into the street. They had heard a loud noise.
有些人跑上了街,他们听到很响的嘈杂声.
九、时态的一致
在一些从句（主要是宾语从句）中谓语动词的时态,常常受主句中谓语动词时态的影响,这叫做时态的一致.
时态的一致通常分以下一些情况下考虑：
1．当主句中的谓语动词是现在时态或将来时态,在这种情况下,从句的谓语动词可以用任何所需时态.如：
I know that Mr. Brown is a good teacher. 我知道布朗先生是一名好老师.
She believes that he was once a solider. 她相信他以前曾是一名士兵.
He will tell us what he is going to do. 他将告诉我们他要干吗.
2．当主句中的谓语动词是过去的某种时态,在这种情况下,从句的谓语动词可以分为下面三种情况：
（1）如果从句的谓语动词所表示的动作与主句的谓语动词所表示的动作同时发生,从句则需要用一般过去时或过去进行时.如：
He was wondering where he could put the box.
他不知道该把这个盒子放在哪里.
The students were talking while the teacher was writing on the blackboard.
老师在黑板上板书时,学生们在说话.
（2）如果从句的谓语动词所表示的动作发生在主语的谓语动作之前,从句则要用过去完成时.如：
The train had left when they got to the station. 当他们到达车站时,火车已经开走了.
He said his father had been dead for twenty years. 他说他父亲已经去世二十年了.
（3）如果从句的谓语动词所表示的动作发生在主语的谓语动作之后,从句则要用过去将来时.如：
She said she would finish the work tonight. 她说过她将于今晚完成这项工作.
We knew that it was going to snow. 我们知道将要下雪了.
3．当从句所说明的为一般真理或客观事实时,无论主句为何时态,从句不受影响,仍用现在时态.
The boy was told that the moon travels around the earth. 男孩被告知月亮绕着地球转.
Everybody knows that sixty minutes make an hour. 人人都知道一小时有六十分钟.
