We use the simple present tense when:
|
John drives a taxi. |
||
|
past |
present |
future |
|
|
||
|
It is John's job to drive a taxi. He does it every day. Past, present and future. |

Look at these examples:
Note that with the verb to be, we can also use the simple present tense for situations that are not general. We can use the simple present tense to talk about now. Look at these examples of the verb to be in the present simple tense—some of them are general, some of them are now:
|
Am I right? |
||
|
past |
present |
future |
|
|
||
|
The situation is now. |
||
|
I am not fat. |

|

|
The situation is general. Past, present and future. |

We often use the present continuous tense in English. It is very different from the simple present tense, both in structure and in use.
The structure of the present continuous tense is:
|
subject |
+ |
auxiliary verb |
+ |
main verb |
|
|
|
be |
|
base + ing |
Look at these examples:
|
|
subject |

|
? |
Is |
he |
|
watching |

|
? |

We use the present continuous tense to talk about:
a) for action happening exactly now
|
I am eating my lunch. |
|||||
|
past |
present |
future |
|||
|
|||||
|
|
The action is happening now. |
|
|||
Look at these examples. Right now you are looking at this screen and at the same time...
|
|
|
|
|
...the pages are turning. |
...the candle is burning. |
...the numbers are spinning. |
b) for action happening around now
The action may not be happening exactly now, but it is happening just before and just after now, and it is not permanent or habitual.
|
John is going out with Mary. |
||||||||||||||||
|
past |
present |
future |
||||||||||||||
|
||||||||||||||||
|
|
The action is happening around now. |
|
||||||||||||||
Look at these examples:
We can also use the present continuous tense to talk about the future—if we add a future word!! We must add (or understand from the context) a future word. "Future words" include, for example, tomorrow, next year, in June, at Christmas etc. We only use the present continuous tense to talk about the future when we have planned to do something before we speak. We have already made a decision and a plan before speaking.
|
I am taking my exam next month. |
|||||
|
past |
present |
future |
|||
|
|||||
|
|
A firm plan or programme exists now. |
The action is in the future. |
|||
Look at these examples:
In these examples, we have a firm plan or programme before speaking. The decision and plan were made before speaking.
We make the present continuous tense by adding -ing to the base verb. Normally it's simple—we just add -ing. But sometimes we have to change the word a little. Perhaps we double the last letter, or we drop a letter. Here are the rules to help you know how to spell the present continuous tense.
|
Basic rule |
Just add -ing to the base verb: |
||||||||||
|
work |
> |
working |
|||||||||
|
play |
> |
playing |
|||||||||
|
assist |
> |
assisting |
|||||||||
|
see |
> |
seeing |
|||||||||
|
be |
> |
being |
|||||||||
|
Exception 1 |
If the base verb ends in consonant + stressed vowel + consonant, double the last letter:
(vowels = a, e, i, o, u) |
||||||||||
|
stop |
> |
stopping |
|||||||||
|
run |
> |
running |
|||||||||
|
begin |
> |
beginning |
|||||||||
|
Note that this exception does not apply when the last syllable of the base verb is not stressed: |
|||||||||||
|
open |
> |
opening |
|||||||||
|
Exception 2 |
If the base verb ends in ie, change the ie to y: |
||||||||||
|
lie |
> |
lying |
|||||||||
|
die |
> |
dying |
|||||||||
|
Exception 3 |
If the base verb ends in vowel + consonant + e, omit the e: |
||||||||||
|
come |
> |
coming |
|||||||||
|
mistake |
> |
mistaking |
|||||||||

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.
The structure of the present perfect tense is:
|
subject |
+ |
auxiliary verb |
+ |
main verb |
|
|
|
have |
|
past participle |
Here are some examples of the present perfect tense:
|
|
subject |
auxiliary verb |
|
main verb |
|
|
+ |
I |
have |
|
seen |
ET. |
|
+ |
You |
have |
|
eaten |
mine. |
|
- |
She |
has |
not |
been |
to Rome. |
|
- |
We |
have |
not |
played |
football. |
|
? |
Have |
you |
|
finished? |
|
|
? |
Have |
they |
|
done |
it? |
When we use the present perfect tense in speaking, we usually contract the subject and auxiliary verb. We also sometimes do this when we write.
|
I have |
I've |
|
You have |
You've |
|
He has |
He's |
|
We have |
We've |
|
They have |
They've |
Here are some examples:
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:
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. |
|||||
|
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.
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. |
|
|
Has the price gone up? |
||
|
past |
present |
future |
|
+ |
- |
|
|
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.
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. |
||||||||||
|
past |
present |
future |
||||||||
|
||||||||||
|
The situation started in the past. |
It continues up to now. |
(It will probably continue into the future.) |

This tense is called the present perfect continuous tense. There is usually a connection with the present or now. There are basically two uses for the present perfect continuous tense:

The past continuous tense is an important tense in English. We use it to say what we were in the middle of doing at a particular moment in the past.
The structure of the past continuous tense is:
|
subject |
+ |
auxiliary verb BE |
+ |
main verb |
|
|
conjugated in simple past tense |
|
present participle |
|
|
was |
base + ing |
|||
For negative sentences in the past continuous 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 continuous tense:
|
|
subject |
auxiliary verb |
|
main verb |
|
|
+ |
I |
was |
|
watching |
TV. |
|
+ |
You |
were |
|
working |
hard. |
|
- |
He, she, it |
was |
not |
helping |
Mary. |
|
- |
We |
were |
not |
joking. |
|
|
? |
Were |
you |
|
being |
silly? |
|
? |
Were |
they |
|
playing |
football? |
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 |
|||
|
|||||
|
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:
|
|
|
|
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..."
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:
|
past |
present |
future |
|||||||||
|
Long action. |
|
|
|||||||||
|
|||||||||||
|
Short action. |
|
|
|||||||||
We can join these two actions with when:
(Notice that "when you telephoned" is also a way of defining the time [8pm].)
We use:
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.
Use the past continuous tense or simple past tense as appropriate.
|
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".
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 |
he'd |
|
we had |
we'd |
|
they had |
they'd |
|
|
|
|
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 had left when we arrived. |
||||||||
|
past |
present |
future |
||||||
|
Train leaves in past at 9am. |
|
|
||||||
|
||||||||
|
We arrive in past at 9.15am. |
|
|
||||||
Look at some more examples:
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 participle |
|
present participle |
|
|
had |

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

Had |
you |
|
been |
drinking? |
|
|

Had |
they |
|
been |

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

I'd been |
|
you had been |
you'd been |
|
he had |
he'd been |
|
we had been |
we'd been |
|
they had been |

The past perfect continuous tense is like the past perfect tense, but it expresses longer actions in the past before another action in the past. For example:
|
Ram had been waiting for two hours when I arrived. |
||||||||
|
past |
present |
future |
||||||
|
Ram starts waiting in past at 9am. |
|
|
||||||
|
||||||||
|
I arrive in past at 11am. |
|
|
||||||
Here are some more examples:
You can sometimes think of the past perfect continuous tense like the present perfect continuous tense, but instead of the time being now the time is past.

For example, imagine that you meet Ram at 11am. Ram says to you:
Later, you tell your friends:
|
I will sing |
The simple future tense is often called will, because we make the simple future tense with the modal auxiliary will.
The structure of the simple future tense is:
|
subject |
+ |
auxiliary verb WILL |
+ |
main verb |
|
|
invariable |
|
base |
|
|
will |
V1 |
|||
For negative sentences in the simple future 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 simple future tense:
|
|
subject |
auxiliary verb |
|
main verb |
|
|
+ |
I |
will |
|
open |
the door. |
|
+ |
You |
will |
|
finish |
before me. |
|
- |
She |
will |
not |
be |
at school tomorrow. |
|
- |
We |
will |
not |
leave |
yet. |
|
? |
Will |
you |
|
arrive |
on time? |
|
? |
Will |
they |
|
want |
dinner? |
When we use the simple future tense in speaking, we often contract the subject and auxiliary verb:
|
I will |
I'll |
|
you will |
you'll |
|
he will |
he'll |
|
we will |
we'll |
|
they will |
they'll |
For negative sentences in the simple future tense, we contract with won't, like this:
|
I will not |
I won't |
|
you will not |
you won't |
|
he will not |
he won't |
|
we will not |
we won't |
|
they will not |
they won't |
We use the simple future tense when there is no plan or decision to do something before we speak. We make the decision spontaneously at the time of speaking. Look at these examples:
In these examples, we had no firm plan before speaking. The decision is made at the time of speaking.
We often use the simple future tense with the verb to think before it:
We often use the simple future tense to make a prediction about the future. Again, there is no firm plan. We are saying what we think will happen. Here are some examples:
When the main verb is be, we can use the simple future tense even if we have a firm plan or decision before speaking. Examples:
|
I will be singing |

At 4pm tomorrow, I will be working. |
