Use

 

We use the present perfect:

· for actions which happened at an unspecified time in the past. The exact time is not mentioned because it is not important We put more emphasis on the action.

She has found a new job. (When did she find it? We don’t mention the exact time because it is not important. What is important is the fact that she has a new job.)

· for actions which started in the past and still continue in the present.

· with today, this morning/afternoon, etc when these periods of time are not finished at the time of speaking. They have packed three boxes this morning. (It is still morning, so this period of time is not finished.)

Past Simple vs Past Perfect

Form

had + Ved of regular verbs

3rd column of irregular verbs

Example: I had spoken

Use

We use Simple Past if we give past events in the order in which they occurred. However, when we look back from a certain time in the past to tell what had happened before, we use Past Perfect.

Normal order in the past or looking back to an event before a certain time in the past?

Do you just want to tell what happened sometime in the past or do you want to tell what had happened before/up to a certain time in the past?

Simple Past Past Perfect Simple
sometime in the past Example: Jane got up at seven. She opened her birthday presents and then the whole family went to the zoo. before/up to a certain time in the past Example: Before her sixth birthday, Jane had never been to the zoo.

Signal Words

Simple Past Past Perfect Simple
§ first § then § already § up to then § before that day § after*

*Note: "After" is only used as a signal word for Past Perfect if it is followed by a subject + verb, meaning that one action had been completed before another action began (the new action is in Simple Past).

Example: After the family had had breakfast, they went to the zoo.

However, if "after" is followed by object + subject + verb, the verb belongs to the new action and is therefore in Simple Past.

Example: After her visit to the zoo, Jane was exhausted.

More exceptions with signal words

When

Depending on the situation, "when" can be used with Simple Past or Past Perfect. Compare the following examples:

Example: When Jane saw the elephants, she was amazed. (at the same time)

When Jane had seen the elephants, she wanted to see the giraffes. (second action happened after the first action had been completed)

When Jane went to see the elephants, she had already seen the lions. (second action had been completed when the first action took place)

Before

"Before" as well can either be used with Simple Past or Past Perfect. If the action after "before" is a new action, use Simple Past. If the action after "before" started (and was not completed) before a certain time in the past, use Past Perfect. Compare the following examples:

Example: Jane had read a lot about elephants before she went to the zoo.

Jane went to the zoo before she had finished reading her new book about elephants.
