托福的语法中语句的时态疑问有许多，时态有五个疑问要留心的，即格局，意义，比照，共同和活用。在实践使用中，时态的根柢规则并不凌乱，只需多想多用，很快就可以掌控的，至于更多的改变，也完全可以在今后的学习中逐步掌控的。而能用之后咱们又会发现，其实每篇文章里时态的分配都可以有多种方案，就像咱们每自个的穿戴可以有许多种分配相同，咱们时态的用法也可以有多种分配方案，只需能契合体现文章的主题的需要，就大约说是正确的。至于哪种是最佳的方案，则各人有自个的观点，所谓仁者见仁，智者见智了。

雅托邦修改今日就时刻从句中的曩昔结束时来给我们进行解析共享，话不多说，一同来看看吧！

曩昔结束时: 标明在曩昔某时之前就现已结束的动作或状况。

例句：

1.Three days ago he had already finished his homework. [动作]

2.When he was a boy, he had already been a head of the boys. [状况]

曩昔结束进行时是由 had been+如今分词构成，因而无人称改变：I had/I’d been working)they had not/hadn’t been working)had you been working?)had you not/hadn’t you been working?凡不能用于

进行时的动词均不能有这种时态，但动词want(有时还有wish)在外：The boy was delighted with his new knife.He had been wanting one fora long time.留心：这一时态没有被逼语态，像They had been picking ap-ples(他们一向在摘苹果)这样的语句，迩来似的被逼式是Ap-ples had been picked(苹果已摘完)，实践上这两种说法意思并纷歧样。

曩昔结束进行时与曩昔结束时之间的联络，同如今结束进行时与如今结束时之间的联络相同。

标明动作在所说的曩昔某一时刻之前就已初步并持续到那一时刻或许在那一时刻之前刚刚中止时，常常可以用两个时态中的任一个:It was now six and he was tired because he had worked since dawn.(现已6点了，他感到很累，因为他从天亮起一向作业到如今.).恰当于：It was now six and he was tired because he had been working since dawn.(那时正是6点，他因从一大早就干活而累了。)

用曩昔结束时标明的重复的动作，有时可以作为一种接连的动作用曩昔结束进行时标明：　he had tried five times to get her on the phone.(他曾试着打了五次电话要找她。).　He had been trying to get her on the phone.(他一向在试着打电话找她。).

一个用曩昔结束时表达的单一动作和一个用曩昔结束进行时表达的动作不一样:By six o’clock he had repaired the engine.(到6点钟时他现已修好建议机了。).但He had been repairing the engine(他一向在修补建议机)仅告诉咱们他在前面的时刻/前半小时里做啥，而并不告诉咱们这项作业是不是结束。另一个差异是，由曩昔结束进行时标明的动作常持续进行直到或甚至跨越说话的时刻(这个时刻是在曩昔)。而由曩昔结束时标明的动作虽可以发生在这一说话时刻之前不久，但动作与说话之间可以有较长的时刻间隔：He had been painting the door.(他其时一向在油漆门{油漆大约还未干}。)He had painted the door.

曩昔结束时可以与till/until和before连用，偏重一个动作结束或预期将结束，但要留心在till/until+曩昔结束时+一般曩昔时规划中，标明一般序得充曩昔时的动作可以位于标明曩昔结束时的动作之前，而在before+曩昔结束时+一般曩昔时规划中标明一般曩昔时的动作老是经局总着道位于标明曩昔结束时的动作之前。

当然，这只是一般的用法，还有一些另外用法：曩昔结束时在直接引语中的用法。引导动词假定是一般曩昔时，直接引语中的如今结束时在直接引语中要变成曩昔结束时：

He said,‘I’ve been in England for ten years.’（他说：“我现已在英国住了十年了。”）

恰当于:He said that he had been in England for ten years.(他说他在英国现已住了十年。)

He said,’When you’ve worked for a year you’ll get a rise.'(他说：”你作业一年之后，会加薪酬。”)

恰当于：He said that when I’d worked for a year I’d get a rise.(他说我作业一年之后会加薪酬。)

She said,I’ll lend you the book as soon as I have read it myself.’(她说：“我一看完这本书就借给你。”)

恰当于：She said she’d lend me the book as soon as she’d read it herself.（　她说她一看完那本书就借给我。）

直接引语中的一般曩昔时一般也作相同的改变：

He said,‘I knew her well.’（他说：“我曩昔很晓得她。”）

恰当于：He said that he had known her well.（他说他曩昔很晓得她。）
