Using the Past Perfect Tense in English Grammar
The past perfect tense is a verb tense used to express an action that was completed before another action in the past. It is formed by using the auxiliary verb "had" followed by the past participle of the main verb. In this article, we will explore the usage and examples of the past perfect tense.
1. When to use the past perfect tense:
The past perfect tense is used when we want to indicate that one action had already been completed before another action took place in the past. It helps to establish a clear sequence of events.
2. Examples of the past perfect tense:
a) She had already eaten dinner when her friends arrived.
b) By the time I woke up, my sister had already left for work.
c) They had finished the project before the deadline.
In these examples, the past perfect tense is used to show that one action (eating dinner, leaving for work, finishing the project) had already happened before another action (friends arriving, waking up, deadline).
3. Time expressions used with the past perfect tense:
The past perfect tense is often used with time expressions such as "already," "before," "by the time," and "when." These time expressions help to establish the order of events.
4. Common mistakes with the past perfect tense:
a) Confusing the past simple tense with the past perfect tense: It is important to use the past perfect tense when there are two actions in the past, and one action happened before the other.
b) Overusing the past perfect tense: The past perfect tense is used to describe specific actions that happened before another past action. It should not be used for general statements or habitual actions.
In conclusion, the past perfect tense is a useful tool in English grammar to describe actions that happened before another action in the past. By understanding its usage and practicing with examples, learners can improve their overall proficiency in using this tense correctly.

Using the Past Perfect Tense in Narratives
The past perfect tense is a verb tense used to describe actions that were completed before a certain point in the past. It is commonly used in narratives to provide background information or to show the order of events. In this article, we will explore how to use the past perfect tense effectively in narratives.
1. Setting the scene:
When writing a narrative, it is important to establish the background information before introducing the main events. The past perfect tense can be used to describe actions that happened before the main events of the story. This helps to provide context and set the scene for the reader.
2. Showing the order of events:
The past perfect tense is especially useful when there are multiple past actions in a story. It helps to show the chronological order of events by indicating which action happened before another. This clarity in sequencing makes the narrative more coherent and easier to follow.
3. Examples of the past perfect tense in narratives:
a) John had already finished his homework before he went out to play with his friends.
b) The sun had set by the time they reached the top of the mountain.
c) She had never seen such a beautiful sunset until that day.
In these examples, the past perfect tense is used to describe actions that were completed before the main events of the story. It helps to create a sense of time and build the narrative structure.
4. Using time markers:
To effectively use the past perfect tense in narratives, it is important to use appropriate time markers. Time markers such as "already," "by the time," and "before" help to indicate the sequence of events and make the narrative flow smoothly.
In conclusion, the past perfect tense is a useful tool in narratives to provide background information and show the order of events. By understanding its usage and incorporating appropriate time markers, writers can create engaging and well-structured narratives. Practice using the past perfect tense in your writing to improve your storytelling skills.

2、表示由过去的某一时刻开始，一直延续到过去另一时间的动作或状态。如：

标志性词语
过去完成时常见的标志性时间状语主要有：
1、by the end of+过去时间

4、before+过去时间

语法判定
1.由时间状语来判定
一般说来，各种时态都有特定的时间状语。与过去完成时连用的时间状语有：
① by + 过去的时间点。
如：I had finish
昨晚九点我已看完这本小说了。
② by the end of + 过去的时间点。
如：We had learned over two thousand English words by the end of last term. 到上学期末我们已经学了二千多个英语单词。
③ before + 过去的时间点。
如：They had planted six hundred trees before last Wednesday.
在上星期三之前，他们已经种了六百棵树了。
2.由“过去的过去”来判定
过去完成时表示“过去的过去”，是指过去某一动作之前已经发生或完成的动作，即动作有先后关系，动作在前的用过去完成时，在后的用一般过去时。这种用法常出现在：
①宾语从句中
当宾语从句的主句为一般过去时，且从句的动作先于主句的动作时，从句要用过去完成时。如在told, said, knew, heard, thought等动词后的宾语从句。
如：She said that she had seen the film before.
她说她已经看过这部电影了。
②状语从句中
在时间、条件、原因、方式等状语从句中，主、从句的动作发生有先后关系，动作在前的，要用过去完成时，动作在后的要用一般过去时。
如：After he had finished his homework, he went to bed.
做完作业后，他上床睡觉了。
注意：before, after 引导的时间状语从句中，由于 before 和 after 本身已表达了动作的先后关系，若主、从句表示的动作紧密相连，则主、从句都用一般过去时。
如：After he closed the door, he left the classroom.
他关上了门，离开了教室。
③表示意向的动词，如hope, wish, expect, think, intend, mean, suppose等，用过去完成时表示"原本…，未能…"
如：We had hoped that you would come, but you didn't.
我们原本希望你来，但你没有来。
3. 根据上、下文来判定。
如：I met Wang Tao in the street yesterday. We hadn't seen each other since he went to Beijing.
我昨天在街上遇见了王滔。自从他去北京，我们都没有见过面。
