PRESENT PERFECT

Present Perfect Verb Tense

1. Present Perfect - Form

 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

2. Present perfect, function

 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:

  1. An action or situation that started in the past and continues in the present. Example: I have lived in Bristol since 1984 (= and I still do.)
  2. An action performed during a period that has not yet finished. Example: She has been to the cinema twice this week (= and the week isn’t over yet.)
  3. A repeated action in an unspecified period between the past and now. Example: We have visited Portugal several times.
  4. An action that was completed in the very recent past, (expressed by ’just’). Example: I have just finished my work.
  5. An action when the time is not important. Example: He has read ’War and Peace’(the result of his reading is important)

Note: When we want to give or ask details about when, where, who, we use the simple pastExample: He read ’War and Peace’ last week.

Examples:

1. Actions started in the past and continuing in the present.

  • They haven’t lived here for years.
  • She has worked in the bank for five years.
  • We have had the same car for ten years.
  • Have you played the piano since you were a child?

2. When the time period referred to has not finished.

  • I have worked hard this week.
  • It has rained a lot this year.
  • We haven’t seen her today.

3. Actions repeated in an unspecified period between the past and now.

  • They have seen that film six times.
  • It has happened several times already.
  • She has visited them frequently.
  • We have eaten at that restaurant many times.

4. Actions completed in the very recent past (+just).

  • Have you just finished work?
  • have just eaten.
  • We have just seen her.
  • Has he just left?

5. When the precise time of the action is not important or not known.

  • Someone has eaten my soup!
  • Have you seen ’Gone with the Wind’?
  • She’s studied Japanese, Russian and English.

SIMPLE PAST vs PRESENT PERFECT

                    20111122225946-pperfect-past.jpg

Simple Past

Present Perfect Simple

Irregular verbs: see 2nd column of irregular verbs

Example: I spoke

Irregular verbs: have/has + 3rd column of irregular verbs

Example:

I / you / we / they have spoken.
he / she / it has spoken
 

Regular verbs: have/has + infinitive + ed

Example: I / you / we / they have worked
he / she / it has worked

 

 

Exceptions when adding ’ed’:

  • when the final letter is e, only add d. Example: love - loved
  • after a short, stressed vowel, the final consonant is doubled. Example: admit - admitted
  • final l is always doubled in British English (not in American English). Example: travel - travelled
  • after a consonant, final y becomes i (but: not after a vowel). Example: worry - worried, but: play - played

Use

In British English, the use of Simple Past and Present Perfect is quite strict. As soon as a time expression in the past is given, you have to use Simple Past. If there are no signal words, you must decide if we just talk about an action in the past or if its consequence in the present is important.

Certain time in the past or just / already /yet?

Do you want to express that an action happened at a certain time in the past (even if it was just a few seconds ago) or that an action has just /already / not yet happened?

Simple PastPresent Perfect Simple

certain time in the past

Example: I phoned Mary 2 minutes ago.

just / already / not yet

Example: I have just phoned Mary.

Certain event in the past or how often so far?

Do you want to express when a certain action took place or whether / how often an action has happened till now?

Simple PastPresent Perfect Simple

certain event in the past

Example: He went to Canada last summer.

whether / how often till now

Example: Have you ever been to Canada? I have been to Canada twice.

Emphasis on action or result?

Do you just want to express what happened in the past? Or do you want to emphasise the result (a past action’s consequence in the present)?

Simple PastPresent Perfect Simple

Emphasis on action

Example:  I bought a new bike. (just telling what I did in the past.)

Emphasis on result

Example: I have bought a new bike. (with this sentence I actually want to express that I have a new bike now.)

PRESENT PERFECT with FOR, SINCE, JUST, BEFORE, ALREADY, YET

Present Perfect + for and since

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.

For + a period of time

  • for six years, for a week, for a month, for hours, for two hours.
  • I have worked here for five years.

Since + a point in time

  • since this morning, since last week, since yesterday,
  • since I was a child, since Wednesday, since 2 o’clock.
  • I have worked here since 1990.

present perfect with for

  • She has lived here for twenty years.
  • We have taught at this school for a long time.
  • Alice has been married for three months.
  • They have been at the hotel for a week.

present perfect with since

  • She has lived here since 1980.
  • We have taught at this school since 1965
  • Alice has been married since March 2nd.
  • They have been at the hotel since last Tuesday.

 

Present perfect + just, before, already and yet

PRESENT PERFECT + just and before

Just

indicates that the action has happened in the very recent past and it is completed, e.g.
a. I’ve just lost my car keys and can’t leave for work.
b. Don’t call John, I’ve just done it.

Position

Just can be placed before the main verb (past participle).

Before

indicates the existence of past events, and emphasizing the pastness of the event with a redundant before e.g.
a. She has seen the movie before.
b. I have met her before the summer.

Position

Before is usually placed at the end of the sentence.

PRESENT PERFECT + already and yet

refers to an action that has happened at an unspecified time before now. It suggests that there is no need for repetition, e.g.
a. I’ve already drunk three coffees this morning. (and you’re offering me another one!)
b. Don’t write to John, I’ve already done it.

It is also used in questions:

  • Have you already written to John?
  • Has she finished her homework already?

Position

already can be placed before the main verb (past participle) or at the end of the sentence:

  • I have already been to Tokyo.
  • I have been to Tokyo already.

Yet

is used in negative statements and questions, to mean (not) in the period of time between before now and now, (not) up to and including the present. e.g.

  • Have you met Judy yet?
  • I haven’t visited the Tate Gallery yet.
  • Has he arrived yet?
  • They haven’t eaten yet.

Position

Yet is usually placed at the end of the sentence.

SPAIN'S CLIMATE ZONES

20131117221951-spain-climate-map.gif

The image of Spain’s climate abroad has traditionally been one of blue skies and sun, while in reality it is as varied as the country’s geography. At least five different climate zones characterize the Spanish climate due to the Iberian Peninsula’s position between tropical (hot) and polar (cold) wind currents.

20 de noviembre: DÍA INTERNACIONAL DE LA INFANCIA

20131119170214-derechosdelnino-dia.jpg

Los niños, son el futuro de nuestra especie, y como tal, han de ser tratados de una forma especial, estando sus derechos fundamentales por encima de cualquier interés, ya sea político, económico o religioso.

Para salvaguardar su integridad, existe la declaración de los derechos del niño, redactada en 1925 por Save The Children y enmendada y reorganizada en 1959 por las Naciones Unidas.

La infancia es un periodo en cual se configura nuestra persona, y por ello, los niños han de recibir una educación de calidad, una nutrición digna, protección frente a las enfermedades, y un derecho al ocio que en muchas ocasiones, forma a este igual o más que la propia escuela. Como colectivo especialmente vulnerable, las leyes han de ser más severas en lo que respecta a los abusos frente a ellos, ya sean de cualquier tipo, y las instituciones públicas, han de velar por su bienestar y su amparo, garantizando sus derechos en cualquier circunstancia.

Los derechos fundamentales del niño son:

  • A la vida.
  • A la salud.
  • Al descanso, el esparcimiento, el juego, la creatividad y las actividades recreativas.
  • A la libertad de expresión y a compartir sus puntos de vista con otros.
  • A un nombre y una nacionalidad.
  • A una familia.
  • A la protección durante los conflictos armados.
  • A la libertad de pensamiento, conciencia y religión.
  • A la protección contra el descuido o trato negligente.
  • A la protección contra el trabajo infantil y contra la explotación económica en general.
  • A la educación, que será gratuita y obligatoria por lo menos en las etapas elementales.

Queremos agradecer a todas las personas que, de una forma u otra, ayudan a que día a día los infantes puedan crecer felices, asegurando un futuro a nuestra especie,  respetando a los demás y por encima de todo, siendo felices, porque al fin y al cabo todos en mayor o menor medida, seguimos siendo niños.
