Past Perfect Tense

I had sung

The past perfect tense is quite an easy tense to understand and to use. This tense talks about the "past in the past".

How do we make the Past Perfect Tense?

The structure of the past perfect tense is:

subject	+	auxiliary verb HAVE	+	main verb
		conjugated in simple past tense		past participle
		had		V3

For negative sentences in the past perfect tense, we insert not between the auxiliary verb and main verb. For question sentences, we exchange the subject and auxiliary verb. Look at these example sentences with the past perfect tense:

	subject	auxiliary verb		main verb
+	I	had		finished	my work.
+	You	had		stopped	before me.
-	She	had	not	gone	to school.
-	We	had	not	left.
?	Had	you		arrived?
?	Had	they		eaten	dinner?

When speaking with the past perfect tense, we often contract the subject and auxiliary verb:

I had	I'd
you had	you'd
he had she had it had	he'd she'd it'd
we had	we'd
they had	they'd

How do we use the Past Perfect Tense?

The past perfect tense expresses action in the past before another action in the past. This is the past in the past. For example:

• The train left at 9am. We arrived at 9.15am. When we arrived, the train had left.

The train had left when we arrived.
past	present	future
Train leaves in past at 9am.
9 9.15
We arrive in past at 9.15am.

Look at some more examples:

• I wasn't hungry. I had just eaten.
• They were hungry. They had not eaten for five hours.
• I didn't know who he was. I had never seen him before.
• "Mary wasn't at home when I arrived."
  "Really? Where had she gone?"

You can sometimes think of the past perfect tense like the present perfect tense, but instead of the time being now the time is past.

past perfect tense				present perfect tense
had | done | > |					have | done | > |
past	now	future		past	now	future

For example, imagine that you arrive at the station at 9.15am. The stationmaster says to you:

• "You are too late. The train has left."

Later, you tell your friends:

• "We were too late. The train had left."

We often use the past perfect tense in reported speech after verbs like said, told, asked, thought, wondered:
Look at these examples:

• He told us that the train had left.
• I thought I had met her before, but I was wrong.
• He explained that he had closed the window because of the rain.
• I wondered if I had been there before.
• I asked them why they had not finished.

Present Perfect Tense

I have sung

The present perfect tense is a rather important tense in English, but it gives speakers of some languages a difficult time. That is because it uses concepts or ideas that do not exist in those languages. In fact, the structure of the present perfect tense is very simple. The problems come with the use of the tense. In addition, there are some differences in usage between British and American English.

How do we make the Present Perfect Tense?

The structure of the present perfect tense is:

subject	+	auxiliary verb	+	main verb

How do we use the Present Perfect Tense?

This tense is called the present perfect tense. There is always a connection with the past and with the present. There are basically three uses for the present perfect tense:

1. experience
2. change
3. continuing situation

1. Present perfect tense for experience

We often use the present perfect tense to talk about experience from the past. We are not interested in when you did something. We only want to know if you did it:

I have seen ET. He has lived in Bangkok. Have you been there? We have never eaten caviar.
past	present	future
!!!
The action or state was in the past.	In my head, I have a memory now.

Connection with past: the event was in the past.
Connection with present: in my head, now, I have a memory of the event; I know something about the event; I have experience of it.

2. Present perfect tense for change

We also use the present perfect tense to talk about a change or new information:

I have bought a car.
past	present	future
-	+
Last week I didn't have a car.	Now I have a car.

 

John has broken his leg.
past	present	future
+	-
Yesterday John had a good leg.	Now he has a bad leg.

Was the price $1.50 yesterday?	Is the price $1.70 today?

 

The police have arrested the killer.
past	present	future
-	+
Yesterday the killer was free.	Now he is in prison.

Connection with past: the past is the opposite of the present.
Connection with present: the present is the opposite of the past.

3. Present perfect tense for continuing situation

We often use the present perfect tense to talk about a continuing situation. This is a state that started in the past and continues in the present (and will probably continue into the future). This is a state (not an action). We usually use for or since with this structure.

I have worked here since June. He has been ill for 2 days. How long have you known Tara?
past	present	future
The situation started in the past.	It continues up to now.	(It will probably continue into the future.)

Connection with past: the situation started in the past.
Connection with present: the situation continues in the present.

Structure | Use | Quiz How do we use the Past Continuous Tense? The past continuous tense expresses action at a particular moment in the past. The action started before that moment but has not finished at that moment. For example, yesterday I watched a film on TV. The film started at 7pm and finished at 9pm. At 8pm yesterday, I was watching TV. past present future 8pm At 8pm, I was in the middle of watching TV. When we use the past continuous tense, our listener usually knows or understands what time we are talking about. Look at these examples: I was working at 10pm last night. They were not playing football at 9am this morning. What were you doing at 10pm last night? What were you doing when he arrived? She was cooking when I telephoned her. We were having dinner when it started to rain. Ram went home early because it was snowing. Some verbs cannot be used in continuous/progressive tenses. We often use the past continuous tense to "set the scene" in stories. We use it to describe the background situation at the moment when the action begins. Often, the story starts with the past continuous tense and then moves into the simple past tense. Here is an example: " James Bond was driving through town. It was raining. The wind was blowing hard. Nobody was walking in the streets. Suddenly, Bond saw the killer in a telephone box..." Past Continuous Tense + Simple Past Tense We often use the past continuous tense with the simple past tense. We use the past continuous tense to express a long action. And we use the simple past tense to express a short action that happens in the middle of the long action. We can join the two ideas with when or while. In the following example, we have two actions: long action (watching TV), expressed with past continuous tense short action (telephoned), expressed with simple past tense past present future Long action. I was watching TV at 8pm. 8pm You telephoned at 8pm. Short action. We can join these two actions with when: I was watching TV when you telephoned. (Notice that "when you telephoned" is also a way of defining the time [8pm].) We use: when + short action (simple past tense) while + long action (past continuous tense) There are four basic combinations: I was walking past the car when it exploded. When the car exploded I was walking past it. The car exploded while I was walking past it. While I was walking past the car it exploded. Notice that the long action and short action are relative. "Watching TV" took a few hours. "Telephoned" took a few seconds. "Walking past the car" took a few seconds. "Exploded" took a few milliseconds.
