Breve resumen en castellano

VERBOS MODALES ¿Qué significan y cuándo se utilizan?

Los significados de estos verbos son muchos y dependen del contexto. Pueden ir seguidos del
infinitivo (play,go, do) o del infinitivo perfecto (have played, have gone, have done). Si se utiliza el
infinitivo perfecto, entonces siempre se refiere a una acción acaecida en el pasado.
She may buy a new car
She may have bought a new car
You should listen to me
Youshould have listened to me

 
Can, Could, May, Might

Estos cuatro verbos modales significan “poder” hacer algo en sus diversos sentidos de capacidad
(ability), posibilidad (possibility), peticiones y permiso (request & permission). “Can” y “May” se
traducen por “puedo” y “Could” y “Might” por “podría”, pero hay que tener en cuenta varios aspectosfundamentales entre ellos.
Can / May (possibility)
·
I can watch the Simpsons tonight
(“Puedoverlos”, no hay problema)
·
I may watch the Simpsons tonight
(“Puede quelos vea”, no lo sé) 

Can/ Could (ability)

la mayoría de los verbos modales, entre ellos “Can”, no tienen ni pasado ni otros tiempos verbales. Sin embargo, hay una excepción a esta regla. Si el verbo “Can”significa “poder” en el
sentido de capacidad, de saber hacer algo, “Could” expresa la idea de que se
podía hacer algo en el pasado.
·
She can resist a lot when running
(“Puede resistir mucho corriendo”
Presente)
·
She could resist a lot when running
(“Podía resistir mucho corriendo
Pasado)
Be able to
Significa “poder”, “ser capaz de” y sustituye a can en todas aquellas formas verbales de que este
verbo carece, sobre todo en el futuro.
·
I will never be able to pass my driving test.
Must, Have to
Tienen que ver con la idea de obligac
ión y sus significados son casi idénticos, “Must” significa “deber”
y “Have to” significa “tener que”.
·
I
must/have to study for the exam (misma idea)
De hecho, “Have to” sustituye a “Must” en todas aquellas formas de que este verbo carece, sobre
todo en el pasado y el futuro.
·
Michael had to go to the hospital because his father had an accident.
·
You will have to call the doctor if she has a temperature.
Sin embargo, en la forma negativa, ambos verbos significan cosas completamente distintas: mustn’t
indica que no se debe hacer algo (obligación de no hacer algo), mientras que don’t/doesn’t have to
indica que no se tiene por qué hacer algo, no es necesario (ausencia de obligación o necesidad).
·
You don’t have to speak so fast
(You needn’t speak so fast = “No tienes que...”
·
You mustn’t speak so fast
(It is your obligation not to speak so fast = “No debes...”)


Should, Ought to = “Debería”
Significan lo mismo y se utilizan para dar consejos, aunque “Should” es más frecuente.
·
They should drive more carefully
·
They ought to drive more carefully 

Need to, Needn’t

Ambos indican la necesidad o no de hacer algo.
·
Patrick needs to take a shower more often
·
Sheila needn’t work so hard


Modales perfectos

Como ya hemos dicho, los modales seguidos del infinitivo perfecto (have+pp) se
refieren a un hechoya pasado. Hay muchas posibilidades, pero nos vamos a centrar en los siguientes casos:

Must have+pp

Indica que deduzco o concluyo que debe haber pasado algo. (seguro que...)
·
They haven’t arrived yet. They must have lost their way.
·
The teacher called Keith an idiot. He must have felt very angry. 


May/Might have+pp

Indica la posibilidad de que puede haber pasado algo.
·
Lola may have talked to her ex-boyfriend but she didn’t tell me.
·
I might have read that book before, but I don’t remember.


Can’t have+pp or Couldn't have+pp

Indica que no me creo que haya pasado eso, no me entra en la cabeza.(seguro que no /es imposible que)
·
Tamara can’t have won a Grammy award. That’s impossible!!!
·
My brother can’t have said that. I just don’t believe it


Could, Should/Ought to have+pp


Indican que se podía o debería haber hechoalgo en el pasado, pero que no se hizo.
·
Michael is ill in bed.
o
You could have told me that
o
You should have told me that
o
You ought to have told me that

Shouldn’t/Ought not to, Needn’t have+pp

Indican que no se debería o no se necesitaba haber hecho algo enel pasado, pero que no obstante se
hizo.
·
You shouldn’t have drunk so much
·
You ought not to have drunk so much
·
You needn’t have drunk so much to enjoy the party 

(“No necesitabas...”, pero bebiste)
·
You needn’t have brought blankets
(“No necesitabas haber traído sábanas”, pero las trajiste).

   

MODAL VERBS (THEORY AND EXERCISES) 1º y 2º BACHILLERATO


Un verbo modal es aquel que se usa en combinación con un verbo principal para expresar obligación, prohibición, capacidad o habilidad para realizar alguna tarea, para hacer recomendaciones, etc.

Ex. Ralph can speak three languages.
You know you shouldn´t smoke, so why do you do it?



  • Son verbos incompletos, es decir, les faltan tiempos verbales. No tienen participio ni infinitivo. Al faltarles tiempos, utilizan otros verbos para completar su conjugación. Así, “can” se completa con “be able to” , “must” con “have to”, etc.
  • No llevan -s en la tercera persona del singular del presente simple, excepto el verbo “have (got)” y “be able to”.
  • Todos van seguidos de un verbo en infinitivo sin “to” , excepto “ought to”, “have to”, “be able to” y “used to”.
  • Como no necesitan verbo auxiliar, construyen la interrogativa invirtiendo el orden del sujeto y el verbo, y la negativa añadiendo “not”.
  • Nunca uses “do, does, o did” en las preguntas en las que ya estén otros verbos modales como “can, must, etc..


  1. OBLIGACIÓN

    • Must (deber, tener que): “you must train very hard if you want to be a successful athlete”.
    • Have to (tener que): “I have to get up at six every morning except Sundays”.


NOTA: “must” se utiliza para dar órdenes, mandatos, obligaciones. Si el que habla desea suavizar esta autoridad, se suele usar “have to”. “Have to y must” se complementan porque tienen un significado similar. Por ello se utiliza “have to” en todos los tiempos que faltan a “must” (por ejemplo, “had to” es el pasado de” must” y “will have to” sería el futuro de “must”).

  1. PROHIBICIÓN

    • Mustn´t (no deber): “ You mustn´t make a noise during the exam”.
    • Aren´t/weren´t allowed to (no estar permitido/no estaba permitido): “Teachers aren´t allowed to smoke inside the school”.
    • Can´t/couldn´t (no poder/ no podíamos): “You can´t take photos using a flash in this museum”.
NOTA: “Mustn´t” es el modal más usual para indicar prohibición.

3. NECESIDAD

    • Need (necesitar): “We need to buy some butteries for the camera”.

  1. PERMISO (pedir y dar permiso)

    • Can (poder): “I hate that song! Can I put something different on?” “Yes, you can.”
    • May (poder): “May I use your computer ? Yes, you may”.
    • Could (podría): “Could I use your computer?
    • Are/were allowed to (permitir): “My sister is allowed to use a dictionary in her translation exams at university. Incredible!”.

NOTA: “Can, could y may” son los modales más comunes para pedir y dar permiso. “Can y could” se utiliza en un contexto informal y “May” se utiliza en un contexto formal.

  1. AUSENCIA DE OBLIGACIÓN O DE NECESIDAD

    • Needn´t (no necesitar): “You needn´t give me back my camera until I go on holiday next month.”
    • Don´t have to/didn´t have to (no es necesario que ):”Jimmy doesn´t have to retake any exams; he passed them all first time.
NOTA: En este sentido “don´t have to” tiene un sentido más fuerte que “needn´t”.
En este contexto “have to” necesita el auxiliar ”DO” para interrogar y negar (you don´t have to……/do you have to ….?)

  1. RECOMENDACIONES, SUGERENCIAS, CONSEJOS, OPINIONES

  • Should (debería):”Brian should buy a new computer”
  • Ought to (debería): “Bob ought to be more careful when he is driving: he is a real danger to pedestrians.
  • Could (podrías):” You could ask your parents to lend you some money if you haven´t got enough.
NOTA: “Should” es el modal más común para indicar una recomendación. Es prácticamente idéntico a “ought to” , pero este verbo no es tan frecuente como should.

  1. HABILIDAD, CAPACIDAD Y CONOCIMIENTO (PRESENTE)

  • Can (saber):” Marty can play the guitar better than anyone I know”.

NOTA: El verbo que puede sustituir a “can” en este uso es “know how to” (do you know how to cook good Mexican food?)

8. HABILIDAD, CAPACIDAD Y CONOCIMIENTO (PASADO)

  • Could (sabía): “She was a gifted child and could read when she was only three years old.
  • was/were able to (fue capaz de,pudo ): “I was abroad on holiday at the time of the general Election but I was able to vote by post.”
NOTA: Cuando nos referimos a una habilidad que se tuvo en una ocasión concreta del pasado se utiliza “was able to”.

9. AUSENCIA DE HABILIDAD O CAPACIDAD EN EL PRESENTE

  • Can´t (no sabe):”My father can´t drive but my grandmother can.


  1. AUSENCIA DE HABILIDAD O CAPACIDAD EN EL PASADO

  • Couldn´t ( no sabía/no podía):”Did you know that Einstein couldn´t speak fluently until he was nine?
  • Wasn´t/weren´t able to “no fue capaz de/no pudo); “Despite playing well, they weren´t able to score the goals they needed to qualify”.


  1. POSIBILIDAD/INCERTIDUMBRE

  • Se utiliza “might, may o could” + infinitivo para hablar de posibilidad en el futuro o de posibilidad referida a actividades presentes.
  • May (puede que, tal vez): “Some students may fail the exam”.
  • Might (pudiera ser que): “They might go to the opera, but they prefer rock concerts.
  • Could (podría): “He could be at a friend´s house”.
NOTA: “Could” es menos frecuente que “may y might”
“Might” es una posibilidad más incierta que “May”

  • Se emplea may, might o could + be+ Ving para hablar de actividades que pueden estar ocurriendo en el momento de hablar (Joe might be doing his homework or he could be watching the football on tv.

  1. DEDUCCIONES

Una deducción consiste en llegar a una conclusión a través de una interpretación lógica que se apoya en algún tipo de evidencia. Algunas veces la conclusión es muy probable (estamos seguros de ella o casi seguros) y otras veces, más que ser una conclusión probable, se trata de una conclusión posible (no estamos muy seguros de ella).
  • Must + V infin. (debe ): para referirnos a conclusiones probables expresadas en forma afirmativa de las que estamos seguros o casi seguros. Ex.”Pamela isn´t a t home and I know she works a lot. She must be at work.
  • Can´t + V infinit (no puede): para referirnos a conclusiones probables expresadas en forma negativa de las que estamos seguros o casi seguros. Ex.”Teresa can´t like dancing very much. She hardly ever dances when I see her at the disco.
  • Must/can´t+ be+ Ving : para expresar conclusiones probables de las que estamos seguros o casi seguros y que se refieren a hechos que están ocurriendo en el momento de hablar.Ex: “Chris is very quiet, isn´t he? Yes, he must be thinking about something.

  1. HACER OFRECIMIENTOS

  • Can: “Can I help you” (¿Te puedo ayudar?) INFORMAL
  • Will: “Never mind, I will pick you up tomorrow morning. (No te preocupes, te recogeré mañana por la mañana). FORMAL
  • Would: “Would you like anything from the shop? (¿Querrías algo de la tienda?) FORMAL

  1. PEDIR A OTRA PERSONA QUE HAGA ALGO

  • Can/could. Ex. “Can/could you close the door?” INFORMAL
  • Will/would. Ex. Would/will you close the door, please? FORMAL

  1. EXPRESAR HÁBITOS Y RUTINAS EN EL PASADO

  • Would: “When I was a child we´d go to Scotland every summer” ( Cuando era un niño íbamos a Escocia todos los veranos).

  • Used to: “She used to play with me in the playground when we were at school. (Jugaba conmigo en el patio cuando estábamos en el colegio).

  1. OFRECERSE UNO MISMO PARA HACER ALGO
  • Shall: “shall I carry your bags?(¿Te llevo las bolsas?) FORMAL
  • Can: “Can I carry your bags? (¿Puedo llevarte las bolsas?) INFORMAL
NOTA: “Shall” se utiliza sólo con la primera persona (I/we).


MODALES PERFECTOS

Se forman añadiendo al modal un infinitivo perfecto, cuya estructura es “have + Vparticipio -ed, si es regular o la tercera columna de los verbos irregulares. Se usan para referirnos a acciones pasadas.

  • Needn´t + have +Vparticipio (no necesitaba haber/ no tenía que haber…): para señalar que una persona hizo algo aunque esto no hubiera sido necesario.Ex: “She needn´t have taken a taxi. I would have picked her up if she had phoned me.

  • Should/ought to + have + Vparticipio (debería haber …): para indicar que una acción fue poco sensata o que no se siguió un consejo en el pasado.Ex: “He should have locked the door.

  • May/might/could + have + V participio (puede/podría haber …): para hablar a cerca de hechos que posiblemente ocurrieron en el pasado, pero no tenemos certeza absoluta. Si usamos “might”, la suposición es incluso más remota. Ex: She may have made a mistake

  • Must + have + Vparticipio (debe haber…): Para expresar una conclusión probable expresada en forma afirmativa y que se refiere a un hecho del pasado.Ex: Ferry said he woul phone me but he didn´t. He must have forgotten.

  • Can´t + have + Vparticipio (no puede haber…): Para expresar una conclusión probable expresada en forma negativa de la que estamos seguros o casi seguros y que se refiere a un hecho del pasado.EX: I saw Carolina in the street today. She can´t have gone on holiday yet.

HAVING THINGS DONE/MANDAR HACER ALGO


THE CAUSATIVE: HAVE/GET SOMETHING DONE
Have /get + objeto + participio pasado = I have /get my watch mended

A. Se usa un verbo causativo para expresar las acciones que encargamos a alguien.

She always has her food delivered (en lugar de traerla ella, pide a alguien que se la traiga)
I got my phtograph taken for my passport (otra persona me hizo la foto)

Esta estructura tiene un significado pasivo, puesto que el sustantivo que va en medio recibe la acción expresada por el verbo en participio.

Nota:
a) get también indica que el objeto realiza personalmente la acción o se implica mucho en su ejecución.
When I get my homework done, I’ll match TV

b) have es un poco más formal que get y get es más frecuente que have en la forma imperativa.Example: Get your bedroom tidied at once!
.
Nótese la diferencia entre:

a) I’m going to have/get this chair restored

b) I’m going to restore this chair
En la frase a) yo voy a llevar la silla a alguien para que efectúe la restauración, mientras que en la b) soy yo mismo quien la efectúa.

B. Si quisiéramos mencionar quién hace la acción, podríamos añadir by + el agente al final de la frase.

Susan had her car repaired by a mechanic (Susan llevó el coche a un mecánico para que se lo arreglara)

C. El verbo causativo puede usarse prácticamente en cualquier tiempo, incluso en las formas continuas.

We’re having our house painted this week

Jack will be getting his messages sent by e-mail from now on


TENSE
HAVE/GET SOMETHING DONE
Present Simple
I have/get my hair cut.
Past Simple
I had/got my hair cut.
Present Continuous
I'm having/getting my hair cut.
Past Continuous
I was having/getting my hair cut.
Present Perfect
I have had my hair cut.
Past Perfect
I had had my hair cut.
will
I will have my hair cut.
must
I must have my hair cut.
be going to
I'm going to have my hair cut.

D. La interrogativa y la negativa se forman como las de cualquier otro verbo

Do you have your car serviced regularly?
Did he get his house redecorated last week?
You won’t have your eyes tested next week
I’m not getting my hair cut today.

E. En situaciones en las que se quiere indicar que algo desagradable ha ocurrido en el pasado se suele usar have + objeto + participio
He had his car broken last week
I had my finger bitten during the fight
She had his mobile phone stolen while she was playing in the playground

Other structures



  • As long as, providing (or provided that) and on condition: these expressions meanonlyifand can be used with the same verb forms as conditional sentences:
In Spain you can drive a car as long as you are 18
  • Inversion of subject and verb: this structure is very common in formal English in conditional sentences with should and the past perfect. When inversion is used, we omit if:
Had I known about the transport strike, I would have taken my car.
Should you meet Sheila, tell her the meeting has been postponed.

INVERSION IN CONDITIONAL SENTENCES (ADVANCED LEVEL)


In formal English conditional sentences can be formed by inversion of subject and auxiliary. Also, if is removed.
Consider these examples:
  • Were I you, I would visit my grandfather.
In formal English conditional sentences can be formed by inversion of subject and auxiliary. Also, if is removed.
Consider these examples:
  • Were I you, I would visit my grandfather.

CONDITIONAL CLAUSES
Grammar theory -

Conditional clauses, describe the condition upon which the action in the main clause depends. Their basic structure is the following:
If…………then………………..
Different types of conditional will depend on how possible is that expressed in the conditional clause.
Type 0- neutral type
Here if could be replaced by when and the resulting sentence would be:
'When it was very cold, we switched on the heating.'
IF
PRESENT (or same tense)
PRESENT (or same tense
If
It is very cold/it was very cold
We switch/switched on the heating
Type I- open condition
What happens in the main clause may or may not happen, depending on the conditional cluse
IF
PRESENT
FUTURE, IMPERATIVE, CAN, MAY
If
You want to lose weight,
You will probably be hungry
If
You see her,
Tell her to give me a ring
IMPERATIVE
"AND"/"OR"
FUTURE
Keep working like that
And
You will have an accident
Please sit down
Or
You won't see the show.
Something that may happen is seen as depending on chance or highly improbable.
IF
SHOULD
FUTURE and IMPERATIVE
If
You should find this can difficult to open,
Return to the shop
SHOULD + subject + verb
FUTURE and IMPERATIVE
Should you find my keyholder,
You will telephone me immediately

IF
PAST
CONDITIONAL, COULD, MIGHT
If

You would spend money on fuel
You could drive your friends around
It is less likely that the action in the conditional takes place.

You could see that he's a nasty little guy
WERE + SUBJECT + TO INFINITIVE
CONDITIONAL, COULD, MIGHT

IF
PAST PERFECT
