VERB TENSES
The tense of a verb tells us when the action is, was or will be carried out. There are 9 main tenses in the INDICATIVE MOOD ( in which the verb indicates or shows us something ) He ate all his lunch
| PAST PERFECT an action completed in the past |
PAST
CONTINUOUS an action in the past which was still going on |
SIMPLE PAST an action that happened in the past |
PRESENT
PERFECT an action that is completed now |
SIMPLE
PRESENT an action that is happening now |
PRESENT
CONTINUOUS an action which is happening now but is incomplete |
SIMPLE FUTURE an action that will happen |
FUTURE
CONTINUOUS an action which will go on and does not indicate completion |
FUTURE PERFECT an action that will be completed at some stage in the future |
| I had walked to school | I was walking to school | I walked to school | I have walked to school | I walk to school | I am walking to school | I will walk to school | I will be walking to school | I will have walked to school |
| He ate the cake | ||||||||
| She sings at home | ||||||||
| They have played games | ||||||||
| She will dance tomorrow |
This helps us to use " would" in the present tense
I would like to stay
I would have liked to stay
Past conditional and present conditional are especially used in if clauses
This type of sentecne consists of 2 parts, or clauses: a clasue introduced by IF and another introduced by pronoun ( HE/ IT / THEY/SHE/ETC) PLUS would /would have OR future or present tense
eg.
IN all these sentences, you will notice that the tense of the verb in each clause is different
Eg.
IN the first sentence the first verb (EAT) is in SIMPLE PRESENT TENSE and the second verb ( WILL GET) is in the SIMPLE FUTURE TENSE
IN the second sentence the first verb (ATE) is in the SIMPLE PAST TENSE and the second verb ( WOULD GET) is in the PRESENT CONDITIONAL TENSE
And so on!
Therefore it is correct to say
If I had eaten ithat icecream (PAST PERFECT) I would have gotten fat ( PAST CONDITIONAL)
BUT INCORRECT TO SAY
If I ate that icecream ( SIMPLE PAST ) I would have gotten fat ( PAST CONDITIONAL)
IT SHOULD BE
If I ate icecream I would get fat
WHY ?
Simply put, when the verb in the IF CLAUSE has a HAD before it, then the verb in the OTHER CLAUSE must have a " HAVE " after the "would" and before the verb as in the above example. This is why it is wrong to say
If I ate that icecream ( SIMPLE PAST ) I would have gotten fat ( PAST CONDITIONAL)

DOES NOT CONTAIN HAD DOES CONTAIN HAVE
SPECIAL TENSES WHICH HELP TO SPEAK OF DIFFERENT TIME PERIODS IN A SENTENCE
Where one past action occurred before a second past action you use the pluperfect
I did not know you had already finished
Future perfect used in a similar way - an action will have occurred before another future action
They will have finished when we (will) get home
LETS SEE WHAT IS SIMILAR WITH THE ABOVE TENSES
I didnt know you had finished already
\ /
action in closest past to time of speaking action in further past time of speaking
By the time we get home they will have finished
\ /
action in later future time from time of speech action in closest future time
that is
_______he had eaten ____________I knew___________________TIME OF SPEECH _____________we will get there_________they will have gone_____
