BE CAREFUL!
The simple past in English may look like a tense in your own language, but the meaning may be different.
Regular verbs: base+ede.g. walked, showed, watched, played, smiled, stopped
Irregular verbs: see list of verbs
Subject | Verb | ||
Be | Have | Do | |
I | was | had | did |
You | were | had | did |
He, she, it | was | had | did |
We | were | had | did |
You | were | had | did |
They | were | had | did |
Note:
FFor the negative and interrogative simple past form of "do" as an ordinary verb, use the auxiliary "do", e.g. We didn't do our homework last night. The negative of "have" in the simple past is usually formed using the auxiliary "do", but sometimes by simply adding not or the contraction "n't".
The interrogative form of "have" in the simple past normally uses the auxiliary "do".

The simple past is used to talk about a completed action in a time before now. Duration is not important. The time of the action can be in the recent past or the distant past.
You always use the simple past when you say when something happened, so it is associated with certain past time expressions
Note: the word ago is a useful way of expressing the distance into the past. It is placed afterthe period of time e.g. a week ago, three years ago, a minute ago.
Using the present perfect, we can define a period of time before now by considering its duration,with for + a period of time, or by considering its starting point, with since + a point in time.
The present perfect continuous is made up of two elements:
Subject | has/have been | base+ing |
She | has been | swimming |
Affirmative | |
She has been / She's been | running |
Negative | |
She hasn't been | running |
Interrogative | |
Has she been | running? |
Interrogative negative | |
Hasn't she been | running? |
Affirmative | Negative | Interrogative |
I have been living | I haven't been living | Have I been living? |
You have been living | You haven't been living | Have you been living? |
He, she, it has been living | He hasn't been living | Has she been living? |
We have been living | We haven't been living | Have we been living? |
You have been living | You haven't been living | Have you been living? |
They have been living | They haven't been living | Have they been living? |
The present perfect continuous refers to an unspecified time between 'before now' and 'now'. The speaker is thinking about something that started but perhaps did not finish in that period of time. He/she is interested in the process as well as the result, and this process may still be going on, or may have just finished.
1. Actions that started in the past and continue in the present.
2. Actions that have just finished, but we are interested in the results:
With verbs not normally used in the continuous form, use the present perfect simple. See list of these verbs under 'Present Continuous':
Compare:
Present Perfect | Simple Past |
I have lived in Lyon. | I lived in Lyon in 1989. |
They have eaten Thai food. | They ate Thai food last night. |
Have you seen 'Othello'?. | Where did you see 'Othello'? |
We have been to Ireland. | When did you go to Ireland? |
There is also a difference of attitude that is often more important than the time factor.
The present perfect of any verb is composed of two elements : the appropriate form of the auxiliary verb to have (present tense), plus the past participle of the main verb. The past participle of a regular verb is base+ed, e.g. played, arrived, looked. For irregular verbs, see theTable of irregular verbs in the section called 'Verbs'.

Subject | to have | past participle |

I have walked | I haven't walked | Have I walked? |
You have walked | You haven't walked | Have you walked? |

We have walked | We haven't walked | Have we walked? |

The Present Perfect is used to indicate a link between the present and the past. The time of the action is before now but not specified, and we are often more interested in the resultthan in the action itself.
BE CAREFUL! There may be a verb tense in your language with a similar form, but the meaning is probably NOT the same.
The Present Perfect is used to describe:
Note: When we want to give or ask details about when, where, who, we use the simple past.Example: He read 'War and Peace' last week.
1. Actions started in the past and continuing in the present.
2. When the time period referred to has not finished.
3. Actions repeated in an unspecified period between the past and now.
4. Actions completed in the very recent past (+just).
5. When the precise time of the action is not important or not known.
