SECOND CONDITIONAL
UNREAL POSSIBILITY OR DREAM
the second conditional is like the first conditional. we are still thinking about the future. we are thinking about a particular condition in the future, and the result of this condition. but there is not a real possibility that this condition will happen. for example, you do not have a lottery ticket. is it possible to win?no¡ lottery ticket, no win¡ but maybe you will buy a lottery ticket in the future. so you can think about winning in the future, like a dream. it's not very real, but it's still possible.


IF   CONDITION               RESULT
       past simple              WOULD + base verb
If    I won the lottery       I would buy a car  


notice that we are thinking about a future condition. we use the past simple tense to talk about the future condition. we use WOULD + base verb to talk about the future result. the important thing about the second conditional is that there is an unreal possibility that the condition will happen.


EXAMPLES. 
IF + SIMPLE PAST + SIMPLE CONDITIONAL


-If I were rich, I would buy a castle
-If I were him, I would go and see a doctor
-If elephants had wings, they would be able to fly 



THIRD CONDITIONAL: Imaginary past
The third conditional is used when we are talking about the past and imagining something different from what actually happened:

     CONDITION              RESULT                      WHAT ACTUALLY HAPPENED 
      past perfect      would have + past participle    
IF  I had known        I would have helped              I didn't know and didn't help 

IF  CONDITION                 RESULT                           CERTINTY   
-      past perfect       would have + past participle     
-IF  I had known       I would have helped                  although this didn't happen, the speaker is sure 
                                                                                    about the result
-IF I had known       I could have helped                    although this didn't happen, the result is only a 
                                                                                    possibility
-IF I had known      I might have helped                    although this didn't happen, the result is only a  
                                                                                   possibility
-IF you had known   you should have helped            although this didn't happen, it is only a good 
                                                                                   suggestion or piece of advice

EXAMPLES:  
-If I had known that you were sick, I would have gone to see you 
-If you had saved your  money, you could have bought a laptop
-If you hadn't been late for work so often, they wouldn't have fired you
         

CONDITIONALS

1. ZERO CONDITIONAL: CERTAINTY.                                                                                                       the zero conditional is use for things that are always true as long as the condition is met.

IF     CONDITION                RESULT              SITUATION                                                                              present simple             present simple                                                                                                       
IF  you heat water to                it boils                  fact universal
     100 degrees celsius          

         present simple             present simple

IF  i drink coffee                i get a headache          fact personal

In these examples, the result will always occur if the condition is met, so the time is not important.

EXAMPLES:  
-If i am late for work my boss gets angry
-If I leave the house at 8am, I catch the bus at 8.15am 
-If you heat butter, it melts
-If you put water in a cooler, it freezes
-If you drop ice in water, it floats.
-If iron gets wet, it rusts

FIRT CONDITIONAL
We use first conditional to talk about events which are possible. the conditional clause can refer to the present or the future.

CONDITIONAL CLAUSE                                                      MAIN CLAUSE 
If + present simple                                                                 - will + bare infinitive

if itrains, we will stay at home

.the conditional clause can come before or after the main clause, we use a comma at the end of the conditional clause when it comes first:
IF you don't try harder, you will fail.
you will fail if you don't try harder.

.other structures are possible,depending on what you want to say:
CONDITIONAL CLAUSE                                                        MAIN CLAUSE 
If + present simple                                                                  modal verb                                            
If you behave yourself                                                             you can come

If  + presentsimple                                                                - be going to (future)
If you don't work                                                                    you're going to fail 

If + present simple                                                                - imperative 
If you need anything                                                               ask

If + present continuous                                                        - will + bare infinitive
If we're leaving soon                                                             I'll get my coat

If + present perfect                                                               - will + bare infinitive
If  I've finished                                                                       I'll be able to come


If + present perfect                                                              - modal verb
If you're finished                                                                    you can go out

6.TAG QUESTIONS

a question added to a declarative sentence. usually at the end, to engage the listener, verify that something has been understood, or comfirm that an action is agreed.
common tags include
.won't you?
.wasn't it?
.don't you?
.haven't you?
.okay?
.and right?


example: you are american, aren't you?

RULES OF QUESTIONS TAGS
the english tag questions is composed by an auxiliary verb (did, does, do, will, has, have) and a subjective pronoun. the auxiliary has to agree with the tense of the sentence. if the verb was in the present sente, for example, the tag question uses do or does, if the verb was in a present continuous form, the tag is formed with am, are, is; and if the sentence has a modal verb, then we use the same modal verb in the tag. if the declarative sentence is in positive athen tag question is in negative and vice versa.

mr. cristian works hard,  doesn't he?
(declarative sentence positive) (question tag negative)

mr.cristian doesn't hard, does he?  
(declarative sentence negative) (question tag positive)

EXAMPLES OF TAG ENDINGS IN THE FIVE PRINCIPAL TENSES

PRESENT
she goes there often, doesn't she?
you live here, don't you?
she likes cakles, doesn't she?
we often visit grandma, don't we?


NEGATIVE
she doesn't go there often, does she?
you don't live here, do you?
she doesn't often visit grandma, do we?

SIMPLE PAST
you went to delhi, didn't you?
he was there, wasn't he?
you saw him,didn't you?
they bought the clothes, didn't they?

NEGATIVE
you didn't go to delhi, did you?
he wasn't there, was he?
you didn't see him, did you?
they didn't buy the clothes, did they?

FORMAL FUTURE
you'll be late, won't you?
he'll arrive tonight, won't he?
they'll meet us at school, won't they?

NEGATIVE
you won't be late, will you'
he won't arrive tonight, will he?
they won't meet us at school, will they?

INFORMAL FUTURE
you're going to break that, aren't you?
she is going to sing again, isn't she?
you're going to london, aren't you?

NEGATIVE
you're not going to break that, are you?
she's not going to sing again, is she?

they've lost all the money, haven't they?

NEGATIVE
you haven't seen this before, have you?
she hasn't said that in the past, has she?
they haven't lost all their money, have they?
 

  

5.RELATIVE CLAUSES

there are two types of relative clauses in english: those that add extra information (nondefining relative clauses) and those that modify (or define) the subject of the sentence.

DEFINING CLAUSES
these clauses define the noun and they identify which thing or person we are referring to.
things
''the present which he bought me is beautiful''
people

''the man who has started an english course is from spain''
using whom
whom is used to refer to the objet of the verb
the people with whom i was sitting were very noisy.
however, it is hardly ever used in spoken english. instead, is used with the preposition:

the people who i was i was sitting with were very noisy.
to whom are you speaking=whon are yo
                                           speakingto?

for whom are you buying the present? + who are you buying the present for?  

using that
in spoken english, ''that'' is often used instead of ''which'', ''whom'' or ''who''     

''the present that he bought me is beautiful''
''the man that has started an english course is from spain''

when, where and whose
when: is they another time when (that) i can call you?
where: can you tell me where i can buy wrapping paper?   
whose: (possesive) have you seen the tv show whose catch phrase is deal no deal?

omitting,that, who and which
if the pronoun (''that'',  ''who'',  ''which'') is the object of the verb, it can be omitted.
the company that she works for is based in london (that is an object pronoun)

=the company she works for is based in london (''that can be omitted)

but: the company that employs her is based in london (''that'' is a subject pronoun)
the company employs her (the company is the subject). in this case, it is not possible to omit ''that''. you need the pronoun because it is the subject of the verb

NON DEFINING RELATIVE CLAUSES
these clauses add further information. ''my students, who are all adults are learning english to get a better job''
the textbooks,which the students like, have lots of help ful examples.

commas are used to separate the relative clause from the rest of the sentence.
''that'' cannot be used instead of ''who''  or 
''which'' in non-defining relative clauses.

you can use some, none, and many with of which and of whom to add extra information.

COMPARING DEFINING AND NON-DEFINING RELATIVE CLAUSES
 the meaning of the sentences changes if you use a non-defining clause rather that a defining clause. compare the following:
non defining
the students, who had revised hard, passed the exam. all the students revised and they all passed the exam.

defining
the students who had revised hard passed the exam. only some of the students revised, and these were the ones who passed the exam.    

4.PRESENT PERFECT

A.WHEN TO USE:                       
there are basically three uses for the present perfect tense: 
1.experience
2.change
3.continuing situation 

1.present perfect tense for experience 
we often use the present tense to talk about experience. from the past. we are not interested in when you did something. we only want to know if you did it.

i have seen et.
he has lived in bangkok.
have you been there?
we have never eaten caviar.

PAST                           PRESENT                    FUTURE
the action or                  in my head                  
state was in                   i have a                                
the past                        memory now        

connection with past: the event was in the past         
connection with present: i know something aboul the event; i have experience of it.

2.present perfect tense for change
we also use the present perfect tense to talk about change or new information

I HAVE BOUGHT A CAR
                           PAST                                 PRESENT  +                               FUTURE
           last week i didn't have a car               now, i have a car                   

JHON HAS BROKEN HIS LEG
                          PAST +                                   PRESENT  -                            FUTURE  
          yesterday john had a good leg           now he has abad leg     

HAS THE PRICE GONE UP?
                          PAST +                                   PRESENT -                             FUTURE
        was the prince $1.50 yesterday?      is the prince $1.70 today        

connetion with past: the past is the epposite of the present.
   
connection with present: the present is the opposite of the past

3.PRESENT PERFECT TENSE FOR CONTINUING SITUATION
we often use the present perfect tense to talk about a continuing situation. this is a state that started in the past and continues in the present. (and will probably continue into the future). this is a state (not an action). we usually use for or since with this structure.

i have worked here since june he has beenill for 2 days how long have you known tara?
          
                                    past                               present                             future
                   the situation starte in the past   it continues up to now     (it will probably continue into the future)

connection with past: the situation starte in the past
connection with present: the situation continues in the present

  11.  
    C. STRUCTURES - SIMPLE PRESENT
    AFIRMATIVE SENTENCE                                                                                                              
    in an affirmative sentence the structure is:                                                                                             PRONOUN + VERB + COMPLEMENT                                                                                               I               WORK   IN THE MORNING
    the base (pronoun + verb) in this example is what we call simple present. it indicates facts, habits and real situations, such as:
    .I DANCE
    .I SING
    .I WALK
    .I TALK
    .I LIVE.
    the complement part is the place where you add more meaning to your sentence. you can use an adverb, an adjective, a pleace, a noun.
    .the boy is happy ( adjective )
    .i like chocolate ( noun )
    .he sings everyday ( adverb )
    you can add mor information to the senteaces as well:
    .i like dark chocolate
    .the boy is a happy child
    . he sings everyday in the karaoke
    NEGATIVE SENTENCES
    to create a negative sentence in the simple present you first need to pay attention if the main verb in the phrase is the verb to be or a different verb. if  it's verb to be you just need to add the word not after the verb.
    PRONOUN + VERB + NOT + COMPLEMENT 
    .i am not at home
    .you are not happy
    .he/she/it is not thired
    .we/you/they are not honest
    now,if you are using a verb that is not the verb to be, it is necessary to use an auxiliar. before the verb, do/does, to transform the sentence in a negative one and the word not.
    a very important thing is that you must remember to use do with the persons
    .i/you/we/they and does
    .with he/she/it.
    so, the structure is: 
    PRONOUN + DO + NOT + VERB + COMPLEMENT                                                                  
          I           DO NOT    LIKE CHOCOLATE            
    .he does not work in the morning
    or the contracted form:
    .i don't like chocolate
    .he doesn't work in the morning
    INTERROGATIVE FORM
    the same way you need to check if the verb is to be to create a negative sentence, you have to do the the same to create an interrogative sentence. to make questions using the verb to be is very simple. all you need to do is to change the order of the phrase. in questions, the verb is placed before the pronoun.
    VERB + PRONOUN + COMPLEMENT
    .are you happy?
    .is he a singer?       
    question with different verbs
    the first thing you need is to use the auxiliar do/does
    ¿do/does + pronoun + verb (infinitive) + complement?
    .do you like pasta?
    .does he sing in the opera?
    remember that in questions using the auxiliar do/does the verb is always in the infinitive, it doesn't change from it's original form
    2.SIMPLE PAST                                                                                                                                uses of the simple past
    the uses of the simple past are somewhat similar to the uses of the simple present, except that past states or actions are expressed.                                                                                                           for instance, the simple past can be used to express actions which ocurred at regular intervals in the past.
    .example: last year i drove to medellin once a week
    in addition, the simple past is used to describe situations which existed for a period of time in the past
    .millions of years ago,dinosaurs inhabited the earth
    .george washington was the first president of the united states.
    the simple past is also used to express non-continuous actions which ocurred at a definite time in the past.
    examples:                                                                                                                                            .columbus reached america in 1492                                                                                                      .i graduated from school last year
    STRUCTURE SIMPLE PAST TENSE                                                                                   
    the simpe past tense has the following struture:                                                                                     SUBJECT + PAST TENSE FORM OF THE VERB
    .the glass broke                                                                                                                                   .water boiled                                                                                                                                       .the bird flew up in the sky                                                                                                                   .the child cried
    INTERROGATIVE SENTENCES                                                                                                   simple past tense begin with did. sometimes question words such as who, why, how, where, may precede did.
    .why did you break the window?                                                                                                         .did the child cry?                                                                                                                                 .how did you seehim?                                                                                                                          .whom did you invite?
    VERB ''TO BE'' - PAST TENSE                                                                                                       you use past simple when you want to talk about something at a definite time in the past: yesterday, last night, in 2001.
    the past simple of be is ''was'' or ''were'': the form depends on the subjetc as it is al most always the case:
    A.POSITIVE FORM                                                                                                      
    .i was yesterday                                                                                                                                  .you were yesterday morning                                                                                                                .he was last night 
    B.NEGATIVE FORM
    use was + not (wasn't) or were + not (weren't) to make negative sentences with the verb to be in this tense. 
    .i wasn't at home yesterday .... i was in prison.
    .REGULAR VERBS                                                                                                                           a regular verb is a verb that follows this rule:
    .past form of the verb=present form                                                                                                            of the verb + ed/d
    .for example: work is a regular verb because:
    past form of work=work + ed=worked
    .dance is a regular verb too. that is because: 
    past form of dance=dance + d=danced
    we call the present form a base form, or verb 1.                                                                                  we call the past form verb 2 there is another form called verb 3. that is the form we use in the perfect tenses.
    these are examples of regular verbs                                                                                                     VERB 1: help, open, stop, change                                                                                                       VERB 2: helped, opened, stopped, changed                                                                                         VERB 3: helped, opened, stopped, changed.
    IRREGULAR VERBS                                                                                                                       an irregular verb is a verb that does not follow that rule.                                                                       for example, drink is an irregular verb because the past form of  drink is drank, and not ''drinked''.         go is an irregular verb too. that is because the past form of go is went, and not ''goed''.
    these are examples of irregular verbs:                                                                                                   VERB 1: take, buy, eat, give                                                                                                               VERB 2: took, bought, ate, gave.                                                                                                       VERB 3: taken, bought, eaten, given.
    3.PRESENT CONTINUOUS  
    use the present continuous with normal verbs to express the idea that something is happenning now, at this very moment. it can also be used to show that something is not happening now.            
    examples:                                                                                                                                             .you are learning english now                                                                                                               .are you sleeping?                                                                                                                               .i am not standing.
    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 how ever,we might not be doing it at this exact second.         
    examples: (all 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
    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 uisiting his parents ney weekend?
    USE 4: repetition and irritation with ''always''
    the present continuous words such as ''always''or ''constantly'' expresses the idea that something irratating or shocking often happens. notice that the meaning is like simple present, but with negative emotion. remember to put the words ''always'' or ''constatly'' between ''be''and ''verb + ing''
    examples:                                                                                                                                             .she is always coming to class late                                                                                                         .he is constantly talking.
