Understand English Language Tenses

TENSES


TIME AND TENSE:
Time is a universal non-linguistic concept with three divisions.
1.      The present
2.      The past
3.      The future
Why do we consider time as a non-linguistic concept?
Time is not a linguistic concept because it is within the society and it’s the way people use to perceive actions, ie. It must be represented time in language.

TENSE
Tense is the change of the verb to show time or correspondence of time within the tense.

TYPES OF TENSES
1.      The present tense (the now/ today tense)
2.      The past tense (the yesterday tense)
3.      The future tense (the tomorrow tense)
NB: Tense tells us when certain things happened.

VERBS
What is a verb?
A verb is a word which expresses an action or a state of being.
1.      A verb appears in the base form in the dictionary before making any malnutrition.
2.      “s” form in simple present and “ies” form.
3.      “ing” form in participle form and present continuous form.
4.      “ed” form to form the past tense.

a)      An action
Examples.
(i)                 She teaches in their school.
(ii)               They are cultivating a farm.
(iii)             We are standing up.
(iv)             The moving car crushed him.

b)      A state of being = verbs which are not doing verbs, but being verbs that is verbs which describe states.
Examples.
(i)                 The food is very cold.
(ii)               The athletes are here.
(iii)             Her beautiful dress become dirty.

FORMS OF VERBS
The makes up of verbs. What makes a verb?
There are two ways in which verbs can be formed. So verbs formed from:
a)      Main verbs – these shows an action.
Examples. Walk, eat, play, run, dance, sing, laughs, sees, slides, sleeping, read, take, etc.

b)      Auxiliary verbs (Helping verbs)
Examples. Am, is, was, are, be, been, being, have, has, had, having, were, do, does, done, did, may, might, must, shall, should, will, would, ought, etc.
They help us to know/ locate the time when the action takes place, took place or will take place. In short, they are indicators of time. Also they show us how many times the action is being done.
VERB TENSE
(Change in verb according to time)
Verb tense helps us to talk about time when an action takes place, took place or will take place.

TENSES
TYPES OF VERBS
Verbs can be divided into Regular and Irregular verbs according to how they inflect.
1.      REGULAR VERBS (weak verbs).
The regular verbs are a class of verbs that form their past tense and past participle by adding “d”, “ed” or “ied”.
Examples:
a)      We add “d” to the verbs ending with “e”

2.      IRREGULAR VERS (Strong verbs)
Irregular verbs are verbs which change completely when forming their past tense and past participles. Irregular verbs change internally or do not use “ed” in the expected places. They do not have specific formula or principle in forming their past tense and past participle.
Therefore due to this reason the past tense of irregular verbs often leads to errors either because of pronunciation difficulty.
Example. “sang / sung” or because of confusion of the last “d” sound in the inflictive with the past “d” which is expected. Thus ‘added’ correct because “add” is a regular verb, but “builded” or she “build” are wrong  because “build” is an irregular verb which already ends in “d” and makes its past form by using “built”. Another problem is with send and sent and the special cases where the past tense is the same as the infinitive like “put” and “cast”.

THE PRESENT TENSE (The now tense).
The present tense is used into several forms to express actions which occur at present time.
The forms include:
(i)     The simple present tense
(ii)   The present continuous tense
(iii) The present perfect tense
(iv) The present perfect continuous tense

THE SIMPLE PRESSNT TENSE
This tense is commonly used when referring to an action which happens every day, always, weekly, monthly, generally etc. it is used to express HABITUAL actions or events. Normally its verbs take “s/ es/ ies” when the third person singular (he/she/it) takes the position of the subject.
We use the Simple Present Tense for:-
(i)                 Facts, including scientific facts.
Example:             -A magnet attracts metals.
                 -The earth rotates on its own axis.
(ii)               Repeated actions, habits and customs.
Example: -James picks his nose a lot.
                 -My father gets up at five o’clock every morning.
                 -She seldom goes to school.
(iii)             Abilities
Example: -My sister all dance every day well.
                 -Anna sings beautifully.
In order to make a sentence using simple present tense, the following must be observed.
a)      Singular subject.
He
She                 + “s”, “es” or “ies” added to the verb.
It
John

Example:
1.      Aminagoes to school every day (go).
2.      It rains at our village every day (rain).
3.      John smokes too much on called days (smoke).
4.      She normally visits her uncle on Sunday (visit).
5.      Our cat catches one hundred rats every day (catch).
6.      The baby likes crying (like).
7.      Always she beats other children (beat).
8.      She eats too much when it is meat and rice (eat).
9.      She never collects homework (collect).
10.  This insect disturbs us oftenly (disturb).
11.  He knows the answer (know).

Words used when making simple present tense.
1.      Every day
2.      Often
3.      Always
4.      Normally
5.      Usually
6.      Frequently
7.      Weekly
8.      Generally
9.      Daily
10.  Sometimes
11.  Monthly
12.  He/she/it/never

b)     Plural subject.
When the subject is plural, the main verb remains as it is regardless of its nature. For example whether it ends with “o” or a consonant.
Examples:
(i)                 Pupils normally come to school by bus (come).
(ii)               We go to church every day (go).
(iii)             Teachers normally work very hard to help their students (work)
(iv)             I speak Germany (speak).
NB: This tense can also be used when expressing universal truth.

What are universal truths?
These are actions known worldwide and have been scientifically proved to have truth and will exist the way they are.
Examples:
(a)    Light travels on a straight line (travel)
(b)   The sun sets in the west (set).
(c)    Water boils at 100  (boil).
(d)   Metals expand on heating (expand).

PAST TENSE

The past tense is divided into four forms namely:-
(i)     The simple past tense.
(ii)   The past continuous tense.
(iii) The past perfect tense.
(iv) The past perfect continuous tense.
THE SIMPLE PAST TENSE.
The simple past tense is used to show an action which has been completed in the past. This tense is formed by using the second part of the verb. The simple past tense is formed by adding  “d”, “ed” or “ied” to the root of the verb for the regular verbs.
Since it is difficult to distinguish the verbs that form the simple past tense by adding “d”, “ed” or “ied” from which do not obey this rule, it is advised that any English learner should take each verb individually and learn how its simple past tense is formed.
Key words/ words associated with this tense.
-ago
-yesterday
-the day before
-last week, month, year, century, June, Easter, Christmas, day, night, Friday, evening, Monday, etc.
