going to

Time Future (going to) answers the question: What is going to happen? = What will happen? or What is going to be happening? = What will be happening?. They form: Subject + am / is / are + going to + verb in the present (I am going to work). Subject + am / is / are + going to + be + verb in progressive (I am going to be working).

  Future (going to) I am going to work
she is going to clean her house.

negative
she is not going to clean her house

interrogative
is she going to clean her house

future wiil

the Future with 'Will' (or 'Will' Future) is used to make predictions for the future, ie to discuss unplanned future or uncertain.

WHAT IS IT?
It is used to talk about future predictions based on things that are not so obvious (Ie I think the weather will be great this summer).
We also use this structure to make spontaneous decisions (Ie I'm tired.'ll Go to bed)
When we make promises (Ie I promise I will go to the party).

HOW TO FORM?
 We should note that 'will' is a modal, so follow the basic rules of manners. What we are using 'will' followed by a verb in its base form.
YES: To form the affirmative put the modal 'will' followed by a verb in its base form.

will + subject + verb + rest of sentence.

I'll go to college.
I will go to the university.

 He's going to college.
He'll go to the university.
We should note that manners are not a different form for the third person singular.
Remember that the contracted form of 'will' is different ('ll). In addition, the contracted form can only be used with personal pronouns.
NEGATIVE: To form the negative we have to deny the modal 'will'. It is also important to note that the negative contracted form is 'will not'.

subject + will not + verb + rest of sentence.
I will not go to college.
I will not go to the university.

 As in the affirmative, we can find the complete form (will not) or collapsed form (will not)

INTERROGATIVE: To form the interrogative we must reverse the modal 'will' and the subject.

will + subject + verb + rest of sentence.

Will you go to college?
Will you go to the university?

SHORT ANSWER: To give short answers must use the affirmative or negative of the modal 'will'. Remember that short answers are very common because when we avoid repeating what has already been said.

Will you go to the university?
Yes, I will / No, I will not

You should note that we use the full form in affirmative short answers, as we use the contracted form in negative short answers.

                            past progressive

The past progressive is commonly used to communicate that an activity was happening when another action occurred this time as follows. Subject + was / were + (not) + Verb base (-ing) Example:

she

I was

it

I

They

we were

you

Was / Were + subject + main verb (-ing) ....

Was he working hard yesterday?

Were you reading last friday at 8?

Short answers

Yes, I was: No, I was not

Yes, I was: No, I was not

affirmativo

I was talking When she called.

negative

I was not talk When she called

interrogative

I was talking When She called?

yes I was

presente progresivo 

presente simple 

It is used to talk about habitual actions, generic, occurring with some frequency

Affirmativo
They work in an office,
I works in an office

negative
They do not work in an office
I does not work in an office

interrogative
do they work in an office?
does he work in an office?

They work in an office?
yes they do / no they do not

I work in an office?
yes he does / does not have

The form of the present simple infinitive matches except for the third person singular in which is added a / s' /

I / You / We / They It / She / He
eat eats
run runs

simple past tense 

The simple past tense is used to describe actions that have happened at an earlier time and have been completed, for example:

she cleaned her house.
She clean her house

Both the negative interrogative as auxiliary did is used as
did she clean her house?

Negations can be used in the contracted form did not or did not
she did not clean her house

In expressing simple past sentence means that the action has not

I lost the keys. the lost keys

she lent me a book. She lent me a book

It is also possible to indicate the time when the action is to tell time more accurately:
They Saw the movie last night, they saw the film at night
we went to london yesterday, we went to london yesterday

In order to form a sentence in the past tense must distinguish two types of verbs: regular and Irregular.
The regular is put at the end of the verb ed
If the verb ends in a consonant (y) and transformed into (i) to form the past
cry + ed = cried

Rule of thumb:
We use the past to talk about situations that occurred some time ago.
Normally we use adverbs of time to support the phrase as:
yesterday / yesterday / last week / last week
The questioning is done with the auxiliary did and the infinitive of the verb conjugate.

did she clean her house?


auxiliary
subject
infinitive


How affirmativo with the past of the verb conjugated

she cleaned her house.


last

present perfect

We use the Present Perfect to say that an action happened at an unspecified time before now. The exact time is not important. You CANNOT use the Present Perfect with specific time expressions such as: yesterday, one year ago, last week, when I was a child, when I lived in Japan, at that moment, that day, one day, etc. We CAN use the Present Perfect with unspecific expressions such as: ever, never, once, many times, several times, before, so far, already, yet, etc.
Examples:

• I have seen that movie twenty times.

• I think I have met him once before.

• There have been many earthquakes in California.

• People have traveled to the Moon.

• People have not traveled to Mars.

• Have you read the book yet?

• Nobody has ever climbed that mountain.

• A: Has there ever been a war in the United States?

• B: Yes, there has been a war in the United States
