IMPERATIVES

Imperatives in English are used to give commands or orders.

There are two ways to use them, direct and indirect.

Ej: Para dar ordenes como: 

          Sientate - Presta atencion - No enciendas el foco

Direct way:  In the direct way, the person is transmitting the message

Indirect way: In the indirect form it is one person who says what the other person transmits

EXAMPLES 

Present simple:   

Direct: I like ice cream

Indirect: She said that she liked ice cream

You must take into account the verb tense of the sentence, that will determine the style to which you want to change the sentence.

Past simple:

Directo: I bought a car

Indirect: He said that he bought a car

Causative verbs

Los causative verbs en inglés son aquellos que se utilizan para indicar a una persona o cosa que realice una acción. En otras palabras, se pueden usar para dar instrucciones, con el fin de lograr un objetivo en particular. 

Estos se utilizan para la acción de mandar a...

For example:      We are going to answer this questions with have o get:

Answer

Tag questions

Tag questions are used to ask for agreement or to ask for things, favours, or new information. To determine which, listen to the speaker's tone. A rising tone at the end of a tag question indicates that it is a real question. The speaker wants to know something or wants someone to do something. 

We can add question tags like isn't it?, can you? or didn't they? to a statement to make it into a question. Question tags are more common in speaking than writing.

We often use question tags when we expect the listener to agree with our statement. In this case, when the statement is positive, we use a negative question tag.

HOW DO WE MAKE MODAL VERBS?

To correctly understand and learn modal verbs or modal verbs, it is important to remember that they never conjugate with the grammatical persons in English (I, we, you, they, she, he, it), in other words:

They never have an infinitive (for example, there is no "to will")

They should never be used in a gerund (for example, there is no "coulding")

They will never have a participle (for example, there is no "musted")

Modal verbs can express anything from needs, probabilities, abilities, requests, suggestions, advice, conditions, to difficult and complex ideas such as "modality"; in this way, its meaning can be transformed depending on the verbs and the related context in the sentence.

Modal of ability:

CAN/CAN'T/COULD/COULDN't

Modal of obligation: 

MUST'T or DON'T/DOESN't HAVE TO

Modal of Probability:

MUST + INFINITIVE or MUST + HAVE + PAST PARTICIPLE

Past perfect vs simple past

Ambos se refieren a acciones o estados pasados aunque tienen usos diferentes:

 

 1  El 'simple past' se puede utilizar para hablar de una acción o estado finalizado o para acciones que tienen lugar casi simultáneamente.

 

I painted my house yesterday.

Pinté mi casa ayer.

 

When she saw him she began to cry.

Cuando ella lo vio comenzó a llorar.

 

 2 El 'past perfect' se refiere a una acción o estado que comenzó en el pasado y que es anterior a otra acción también en el pasado.

 

He had cooked the dinner already when she arrived.

Él había hecho la cena cuando ella llegó.

 

Una de las oraciones suele ir introducida por 'when', 'after' o 'before'.

•  When he arrived, she had already gone home.

Cuando él llegó ella ya se había ido a casa.

•  She had already gone home before he arrived.

Ella ya se había ido a casa antes de que él llegara.
