Tenses

There are 16 kinds of tenses in engilsh , today i'll explain some of them to you.

Simple Present Tense

The simple present tense in English is used to describe an action that is regular, true or normal.

We use the present tense:

1. For repeated or regular actions in the present time period.

• I take the train to the office.
• The train to Berlin leaves every hour.
• John sleeps eight hours every night during the week.

2. For facts.

• The President of The USA lives in The White House.
• A dog has four legs.
• We come from Switzerland.

3. For habits.

• I get up early every day.
• Carol brushes her teeth twice a day.
• They travel to their country house every weekend.

4. For things that are always / generally true.

• It rains a lot in winter.
• The Queen of England lives in Buckingham Palace.
• They speak English at work.

Verb Conjugation & Spelling

We form the present tense using the base form of the infinitive (without the TO).

In general, in the third person we add 'S' in the third person.

Subject	Verb	The Rest of the sentence
I / you / we / they	speak / learn	English at home
he / she / it	speaks / learns	English at home

The spelling for the verb in the third person differs depending on the ending of that verb:

1. For verbs that end in -O, -CH, -SH, -SS, -X, or -Z we add -ES in the third person.

• go – goes
• catch – catches
• wash – washes
• kiss – kisses
• fix – fixes
• buzz – buzzes

2. For verbs that end in a consonant + Y, we remove the Y and add -IES.

• marry – marries
• study – studies
• carry – carries
• worry – worries

NOTE: For verbs that end in a vowel + Y, we just add -S.

• play – plays
• enjoy – enjoys
• say – says

Negative Sentences in the Simple Present Tense

To make a negative sentence in English we normally use Don't or Doesn't with all verbs EXCEPT To Be and Modal verbs (can, might, should etc.).

• Affirmative: You speak French.
  Negative: You don't speak French.

You will see that we add don't between the subject and the verb. We use Don't when the subject is I, you, we or they.

• Affirmative: He speaks German.
  Negative: He doesn't speak German.

When the subject is he, she or it, we add doesn't between the subject and the verb to make a negative sentence. Notice that the letter S at the end of the verb in the affirmative sentence (because it is in third person) disappears in the negative sentence. We will see the reason why below.

Negative Contractions

Don't = Do not
Doesn't = Does not

I don't like meat = I do not like meat.

There is no difference in meaning though we normally use contractions in spoken English.

Word Order of Negative Sentences

The following is the word order to construct a basic negative sentence in English in the Present Tense using Don't or Doesn't.

Subject	don't/doesn't	Verb*	The Rest of the sentence
I / you / we / they	don't	have / buy eat / like etc.	cereal for breakfast
he / she / it	doesn't

* Verb: The verb that goes here is the base form of the infinitive = The infinitive without TO before the verb. Instead of the infinitive To have it is just the have part.

Remember that the infinitive is the verb before it is conjugated (changed) and it begins with TO. For example: to have, to eat, to go, to live, to speak etc.

Examples of Negative Sentences with Don't and Doesn't:

• You don't speak Arabic.
• John doesn't speak Italian.
• We don't have time for a rest.
• It doesn't move.
• They don't want to go to the party.
• She doesn't like fish.

Questions in the Simple Present Tense 

To make a question in English we normally use Do or Does. It has no translation in Spanish though it is essential to show we are making a question. It is normally put at the beginning of the question.

• Affirmative: You speak English.
  Question: Do you speak English?

You will see that we add DO at the beginning of the affirmative sentence to make it a question. We use Do when the subject is I, you, we or they.

• Affirmative: He speaks French.
  Question: Does he speak French?

When the subject is he, she or it, we add DOES at the beginning to make the affirmative sentence a question. Notice that the letter S at the end of the verb in the affirmative sentence (because it is in third person) disappears in the question. We will see the reason why below.

We DON'T use Do or Does in questions that have the verb To Be or Modal Verbs (can, must, might, should etc.)

Word Order of Questions with Do and Does

The following is the word order to construct a basic question in English using Do or Does.

Do/Does	Subject	Verb*	The Rest of the sentence
Do	I / you / we / they	have / need want etc.	a new bike?
Does	he / she / it

*Verb: The verb that goes here is the base form of the infinitive = The infinitive without TO before the verb. Instead of the infinitive To have it is just the have part.

Remember that the infinitive is the verb before it is conjugated (changed) and it begins with TO. For example: to have, to eat, to go, to live, to speak etc.

Examples of Questions with Do and Does:

• Do you need a dictionary?
• Does Mary need a dictionary?
• Do we have a meeting now?
• Does it rain a lot in winter?
• Do they want to go to the party?
• Does he like pizza?

 Past Tense

The Simple Past Tense, often just called the Past Tense, is easy to use in English.

If you already know how to use the Present Tense, then the Past Tense will be easy.

In general, the Past Tense is used to talk about something that started and finished at a definite time in the past.

How to form the Past Tense in English

The main rule is that for every verb in English, there is only one form of it in the past tense.

(The exception is the Past tense of To Be, which has two forms: was and were)

This is totally different from other languages such as Spanish, French, Italian etc. where you change the verb ending for every subject.

For example: The past tense of the verb want is wanted.

Wanted is used as the past tense for all subjects/pronouns.

• I wanted
• You wanted
• He wanted
• She wanted
• It wanted
• We wanted
• They wanted

So you just have to learn one word to be able to use it in the past tense. In this case we just needed to learn the one word wanted which can be used for all subjects (or people).

Past Tense Regular Verbs

To change a regular verb into its past tense form, we normally add –ED to the end of the verb.

• play – played
• cook – cooked
• rain – rained
• wait – waited

There are some exceptions with a slight change in spelling which you can see here:

Spelling of words ending in ED.

Examples of sentences using regular verbs in the past tense

• Last night I played my guitar loudly and the neighbors complained.
• She kissed me on the cheek.
• It rained yesterday.
• Angela watched TV all night.
• John wanted to go to the museum.

Note: There are three different ways of pronouncing the –ed at the end of a verb in the past tense.

Negative sentences in the Past Tense

We use didn't (did not) to make a negative sentence in the past tense.

This is for regular AND irregular verbs in English.

(Exception is To Be and Modal Verbs such as Can)

Compare the following:

Present: They don't live in Canada.

Past: They didn't live in Canada.

The main verb (live in the example above) is in its base form (of the infinitive). The auxiliary DIDN'T shows that the sentence is negative AND in the past tense.

NOTICE: The only difference between a negative sentence in the present tense and a negative sentence in the past tense is the change in the auxiliary verb.

Both don't and doesn't in the present tense become didn't in the past tense.

Compare the negative sentences in the examples below:

Present: You don't need a mechanic.

Past: You didn't need a mechanic.

Present: You don't walk to work.

Past: You didn't walk to work.

Present: He doesn't speak Japanese.

Past: He didn't speak Japanese.

Examples of negative sentences in the Past Tense

• I didn't want to go to the dentist.
• She didn't have time.
• You didn't close the door.
• He didn't come to my party.
• They didn't study so they didn't pass the test.
• We didn't sleep well last night.

Questions in the Past Tense

We use did to make a question in the past tense.
This is for regular AND irregular verbs in English.
(Exception is To Be and Modal Verbs such as Can)

Compare the following:

Present: Do they live in France?
Past: Did they live in France?

The main verb (live in the example above) is in its base form (of the infinitive). The auxiliary DID shows that the question is in the past tense.

NOTICE: The only difference between a question in the present tense and a question in the past tense is the change in the auxiliary verb.
Both Do and Does in present tense questions become Didn't in past tense questions.

Compare the questions in the examples below:

Present: Do you need a doctor?
Past: Did you need a doctor?

Present: Do you ride your bike to work?
Past: Did you ride your bike to work?

Present: Does he live in Italy?
Past: Did he live in Italy?

We can also use a question word (Who, What, Why etc.) before DID to ask for more information.

• Did you study? – Yes, I did.
• When did you study? – I studied last night.
• Where did you study? – I studied at the library.

Examples of Questions in the Past Tense

• Did you go to work yesterday?
• Did they arrive on time?
• Did she like the surprise?
• Where did she go?
• What did you do yesterday?
• What did you say? - I didn't say anything.
• Why did we have to come?

Irregular Verbs in the Past Tense

Irregular verbs are ONLY irregular in affirmative/positive sentences.
(An exception to this is with the verb TO BE in the Past Tense).

For example: The past tense of GO is WENT.
It does not end in –ED so it is considered irregular.

The word went is used for all subjects – I, you, we, they, he, she, it.

• I went to the beach
• He went to the park.
• She went to the zoo.
• They went to the library.

BUT, as we mentioned before, it is only in its irregular form (went) in sentences that are affirmative/positive.

Compare the following using GO in the past tense.

• They went to the beach
• They didn't go to the beach --- Didn't shows that we are talking in the past tense.
• Did they go to the beach? --- Did shows that we are talking in the past tense.

Another example with an irregular verb.
The past of EAT is ATE.

• You ate my cake.
• You didn't eat my cake.
• Did you eat my cake?

The present continuous (also called present progressive) is a verb tense which is used to show that an ongoing action is happening now, either at the moment of speech or now in a larger sense. The present continuous can also be used to show that an action is going to take place in the near future. Read on for detailed descriptions, examples, and present continuous exercises.

Present Continuous Forms

The present continuous is formed using am/is/are + present participle. Questions are indicated by inverting the subject and am/is/are. Negatives are made with not.

• Statement: You are watching TV.
• Question: Are you watching TV?
• Negative: You are not watching TV.

Complete List of Present Continuous Forms

Present Continuous Uses

USE 1 Now

Use the present continuous with normal verbs to express the idea that something is happening now, at this very moment. It can also be used to show that something is not happening now.
Examples:

• You are learning English now.
• You are not swimming now.
• Are you sleeping?
• I am sitting.
• I am not standing.
• Is he sitting or standing?
• They are reading their books.
• They are not watching television.
• What are you doing?
• Why aren't you doing your homework?

USE 2 Longer Actions in Progress Now

In English, "now" can mean: this second, today, this month, this year, this century, and so on. Sometimes, we use the present continuous to say that we are in the process of doing a longer action which is in progress; however, we might not be doing it at this exact second.
Examples: (All of these sentences can be said while eating dinner in a restaurant.)

• I am studying to become a doctor.
• I am not studying to become a dentist.
• I am reading the book Tom Sawyer.
• I am not reading any books right now.
• Are you working on any special projects at work?
• Aren't you teaching at the university now?

USE 3 Near Future

Sometimes, speakers use the present continuous to indicate that something will or will not happen in the near future.
Examples:

• I am meeting some friends after work.
• I am not going to the party tonight.
• Is he visiting his parents next weekend?
• Isn't he coming with us tonight?

USE 4 Repetition and Irritation with "Always"

The present continuous with words such as "always" or "constantly" expresses the idea that something irritating or shocking often happens. Notice that the meaning is like simple present, but with negative emotion. Remember to put the words "always" or "constantly" between "be" and "verb+ing."
Examples:

• She is always coming to class late.
• He is constantly talking. I wish he would shut up.
• I don't like them because they are always complaining.

Present Continuous Tips

REMEMBER Non-Continuous Verbs / Mixed Verbs

It is important to remember that non-continuous verbs cannot be used in any continuous tenses. Also, certain non-continuous meanings for mixed verbs cannot be used in continuous tenses. Instead of using present continuous with these verbs, you must use simple present.
Examples:

• She is loving this chocolate ice cream. Not Correct
• She loves this chocolate ice cream. Correct

ADVERB PLACEMENT

The examples below show the placement for grammar adverbs such as: always, only, never, ever, still, just, etc.
Examples:

• You are still watching TV.
• Are you still watching TV?

ACTIVE / PASSIVE

Examples:

• Right now, Tom is writing the letter. Active
• Right now, the letter is being written by Tom. Passive
