Topic : 16 Tenses in English

2. PROLOGUE
The author praises and thanksgiving pray Allah SWT for all His mercy and grace so that
authors can complete a paper for English course work, entitled "16 ENGLISH tenses" just in time.
The author would like to thank all those who have helped to motivate and give useful
suggestions that authors can make this paper as well. In particular, authors thank for the lecturer
Reading II in English who has been given the task of this paper. There by increasing knowledge about
the author that there are 16 tenses in English.
In this paper I will discuss about the various and use of tenses in English. Tenses is the syntax.
As we know, tenses are important in learning English, or the use of English in all respects. Therefore I
would like to discuss about the tenses so that we better understand about the tenses, so we did not err in
applying the English language.
Like the Indonesian language, we must consider the use of tenses in a sentence. What should
we say if you make a sentence which we do, we're doing, and we will do. In English, the pattern of
negative and positive sentences are different, there is the addition of the words in the pattern of
negative sentences. Not much different from Indonesian, English only more specific in the use of the
word. Okay, let's start discussing about the tenses.
The author realized that the paper is still far from perfect, for that author expects criticism and
constructive suggestions for the perfection of this paper. Hopefully this paper is particularly useful to
readers and fellow students in general.

TENSE (NOUN) IS A FORM OF A VERB USED TO INDICATE THE TIME, AND
SOMETIMES THE CONTINUATION OR COMPLETENESS, OF AN ACTION IN RELATION
TO THE TIME OF SPEAKING. (FROM LATIN TEMPUS = TIME). TENSE IS A METHOD
THAT WE USE IN ENGLISH TO REFER TO TIME - PAST, PRESENT AND FUTURE.

CHAPTER I
ENGLISH TENSE SYSTEM
I.1 English Tense System
In some languages, verb tenses are not very important or do not even exist. In English, the
concept of tense is very important.
4

5. In this lesson we look at the idea behind tense, how to avoid confusing tense with time, and the
structure of the basic tenses, with examples using a regular verb, an irregular verb and the verb be.
1. What is Tense?
2. Tense & Time

6. Be
I.2 What is Tense?
Tense (noun) is a form of a verb used to indicate the time, and sometimes the continuation or
completeness, of an action in relation to the time of speaking. (From Latin tempus = time). Tense is a
method that we use in English to refer to time - past, present and future. Many languages use tenses to
talk about time. Other languages have no tenses, but of course they can still talk about time, using
different methods.
So, we talk about time in English with tenses. But, and this is a very big but:
• we can also talk about time without using tenses (for example, going to is a special construction to
talk about the future, it is not a tense)
• one tense does not always talk about one time (see Tense & Time for more about this)
Here are some of the terms used in discussing verbs and tenses :
a. Mood
Indicative mood expresses a simple statement of fact, which can be positive (affirmative) or
negative.
• I like coffee.
• I do not like coffee.
Interrogative mood expresses a question
• Why do you like coffee?
Imperative mood expresses a command
• Sit down!
Subjunctive mood expresses what is imagined or wished or possible
• The President ordered that he attend the meeting.
b. Voice
5

6. Voice shows the relationship of the subject to the action. In the active voice, the subject does
the action (cats eat mice). In the passive voice, the subject receives the action (mice are eaten
by cats). Among other things, we can use voice to help us change the focus of attention.
c. Aspect
Aspect expresses a feature of the action related to time, such as completion or duration. Present
simple and past simple tenses have no aspect, but if we wish we can stress with other tenses
that :
• The action or state referred to by the verb is completed (and often still relevant),
For example : I have emailed the report to Jane.
(so now she has the report)
(This is called perfective aspect, using perfect tenses.)
• The action or state referred to by the verb is in progress or continuing (that is,
uncompleted),
For example : We are eating.
(This is called progressive aspect, using progressive [continuous] tenses.)
I.3 Tense and Time
It is important not to confuse the name of a verb tense with the way we use it to talk
about time.
For example :
a present tense does not always refer to present time:
• I hope it rains tomorrow.
"rains" is present simple, but it refers here to future time (tomorrow).
Or a past tense does not always refer to past time:
• If I had some money now, I could buy it.
"had" is past simple but it refers here to present time (now).
The following examples show how different tenses can be used to talk about different times.
Tense TIME
6

7. Past Present Future
Present Simple
I want a coffee. I leave tomorrow.
She likes coffee
Present Continuous
I am having dinner.
I am taking my exam
next month.
She likes coffee
Present Perfect Simple I have seen ET. I have finished.
Present Perfect
Continuous
I have been playing
tennis.
We have been working for four hours.
Past Simple
I finished one hour
ago.
If she loved you now,
she would marry you.
If you came tomorrow,
you would see her.
Past Continuous
I was working at 2 am
this morning.
Past Perfect Simple
I had not eaten for 24
hours.
Past Perfect Continuous
We had been working
for 3 hours.
If I had been working
now, I would have
missed you.
If I had been working
tomorrow, I could not
have agreed.
Future Simple Hold on. I'll do it now. I'll see you tomorrow.
Future Continuous
I will be working at 9
pm tonight.
Future Perfect Simple
I will have finished by
9pm tonight.
We will have been married for ten years next month.
Future Perfect
Continuous
They may be tired
when you arrive
because they will have
been working.
In 30 minutes, we will have been working for four hours.
I.4 Basic Tenses
For past and present, there are 2 simple tenses + 6 complex tenses (using auxiliary verbs). To
these, we can add 4 "modal tenses" for the future (using modal auxiliary verbs will/shall). This makes a
total of 12 tenses in the active voice. Another 12 tenses are available in the passive voice. So now we
have 24 tenses.

Some grammar books use the word progressive instead of continuous. They are exactly the
same.
The use of tenses in English may be quite complicated, but the structure of English tenses is
actually very simple. The basic structure for a positive sentence is:
subject + auxiliary verb + main verb
An auxiliary verb is used in all tenses. (In the simple present and simple past tenses, the
auxiliary verb is usually suppressed for the affirmative, but it does exist for intensification.) The
following table shows the 12 tenses for the verb to work in the active voice.

I am

I will be
working
continuous perfect

present
participle -ing
I had been
working
I have been

* Technically, there are no future tenses in English. The word will is a modal auxiliary verb and future
tenses are sometimes called "modal tenses". The examples are included here for convenience and
comparison.
I.5 Basic Tenses: Regular Verb
This page shows the basic tenses with the regular verb work. It includes the affirmative or
positive form (+), the negative form (-) and the interrogative or question form (?).
The basic structure is:
positive: + subject + auxiliary verb + main verb
negative: - subject + auxiliary verb + not + main verb
question: ? auxiliary verb + subject + main verb
These are the forms of the main verb that we use to construct the tenses:
base

I.6 Basic Tenses: Irregular Verb
This page shows the basic tenses with the irregular verb sing. It includes the affirmative or
positive form (+), the negative form (-) and the interrogative or question form (?).
The basic structure is:
positive: + subject + auxiliary verb + main verb
negative: - subject + auxiliary verb + not + main verb
question: ? auxiliary verb + subject + main verb
These are the forms of the main verb that we use to construct the tenses:
base verb

The basic structure of tenses for regular verbs and irregular verbs is exactly the same (except to
be). The only difference is that with regular verbs the past and past participle are always the same
(worked, worked), while with irregular verbs the past and past participle are not always the same (sang,
sung). But the structure is the same! It will help you a great deal to really understand that.
10

11. I.7 Basic Tenses: Be
This page shows the basic tenses with the verb be. It includes the affirmative or positive form
(+), the negative form (-) and the interrogative or question form (?).
The basic structure is:
positive (+): subject + auxiliary verb + main verb
negative (-): subject + auxiliary verb + not + main verb
question (?): auxiliary verb + subject + main verb
But for simple past and simple present tenses, the structure is not the same. In fact, it's even
easier. There is no auxiliary verb. Here is the structure:
positive (+) : subject + main verb
negative (-) : subject + main verb + not
question (?) : main verb + subject
These are the forms of the main verb be that we use to construct the tenses:
base past simple past participle present participle present simple
be was, were been being am, are, is
In the following table, we see be conjugated for 12 basic tenses.
