past Progressive

The Past Progressive or past continuous in English is a tense, unlike the simple past is used to talk about the development of a particular action was happening at a given time. It is also used to express an action taking place when someone interrupted and also to refer to actions occurring simultaneously.

Using the Past Progressive in English?
The use of the past progressive in English can be summarized to the simple fact strictly follow its structure, which resembles the present progressive with the exception of the verb To Be is changed to the past tense "was" or "were":


When to use the Past Progressive?
There are three ways or three circumstances in which we can and should use the past progressive, these are:

     When we want to indicate an action that was happening in the past but was interrupted by another action. For example:

     When Laura arrived, I was reading the newspaper
     When Laura arrived, I was reading the newspaper

     OR

     I was reading the newspaper When Laura arrived
     I was reading the newspaper when Laura came

     When two or more actions occur together in the past. For example:

     Alex was reading while Mark was writing
     Alex was reading while Mark was writing

     OR

     While Mark was writing, Alex was reading
     While Mark was writing, Alex was reading

     When an action occurs at a specific time in the past. For example:
     What was I doing at ten o'clock This Morning?
     What was he doing at ten this morning Pundo?

     Linda was singing at eight o'clock last night
     Linda was singing at eight o'clock last night

Continuous or Present Progressive

 
The Present Continuous or Present Progressive tense is used to express actions happening at the same time they are talking, for example:
I am speaking Inglés. I'm speaking English. (It's happening now).
You are reading a book. You're reading a book.
I is studying the lesson. He is studying the lesson.
She is buying a hat. She is buying a hat.
It is raining. It's raining.
We are sleeping. We are sleeping.
You are dancing in the street. You are dancing in the street.
They are walking in the park. They are walking in the park.

This tense is constructed using the Present Simple as a subsidiary of the indicative mood of the verb TO BE as main verb in infinitive termination ING, as shown below:

In the table above uses the verb play (PLAY TO) exemplary.

It can also be used to refer to situations that happen around the time when we talk, but not exactly have to be at this very moment, for example:
I is working in a bank. He is working in a bank.
(It means it's his day job, but not necessarily the person should be working now).

preposisiones

   preposisiones 

 

La definición práctica: las preposiciones sirven de enlace entre palabras dentro de una oración. Dependiendo del sentido de la oración podemos utilizar preposiciones de tiempo, lugar, movimiento, etc.

Las preposiciones propias estan formadas por una sola palabra.

Las preposiciones impropias, normalmente son adjetivos, adverbios y participios que funcionan como preposición, y se forman de dos ó más palabras.

USO DE LAS PREPOSICIONES

Las preposiciones pueden realizar distintas funciones:

- Servir de enlace entre dos palabras o distintos elementos en la oración:

I'll see you at five o'clock / Te veré a las cinco

- Pueden acompañar a un verbo sirviendo de enlace a su complemento. En este caso, pueden no alterar el significado del verbo o alterarlo con lo que constituyen una palabra distinta.

To look / Mirar (no altera el significado del verbo)
To look after / Cuidar de (se altera el significado del verbo)

- Cuando ponemos un verbo después de una preposición, en inglés normalmente se utiliza la forma ' ing' y no el infinitivo.

No deberías ir a la India sin visitar el Taj Mahal.
