What is Present perfect tense?

The Present Perfect Tense is formed with a present tense form of ‘to have’ plus the past participle of the verb (which can be either irregular or regular in form). This tense indicates either that an action was completed (finished or ‘perfected’) at some point in the past or that the action extends to the present.
 
*The Present Perfect is used:-

(1)To indicate completed activities in the immediate past (with just); as,

He has just gone out
He has just struck ten.

(2)To express past actions whose time is not given and not definite; as,

Have you read Gulliver’s travels?
I have never known him to be angry.
Mr.Hari has been to Japan.

(3)To describe past events when we think more of their effect in the present than of the action itself; as,

Gopi has eaten all the biscuits (i.e., there aren’t any left for you).
I have cut my finger (and it is bleeding now).
I have finished my work (now I am free).

(4)To denote an action beginning at some time in the past and continuing up to the present moment (often with since-and for-phrases); as,

I have known him for a long time
He has been ill since last week.
We have lived here for ten years.
We haven’t seen Padma for several months.

*The following adverbs or adverb phrases can also be used with the present perfect(apart from those mentioned above):never, ever(In questions only),so far, till now, yet(in negatives and questions),already,today,this week, this moment,etc.

Note: The Present Perfect is never used with adverbs of past time. We should not say, for example, ‘He has gone to Kolkata yesterday’. In such cases the simple past should be used (‘He went to Kolkata yesterday’).

What is Present continuous tense?

The present continuous tense is formed from the present tense of the verb be and the present participle (-ing form) of a verb.

It is used to express a continued or ongoing action at present time. It expresses an action which is in progress at the time of speaking. For example, a person says, “I am writing a letter”. It means that he is in the process of writing a letter right now. Such actions which are happening at time of speaking are expressed by present continuous tense. Present Continuous tense is also called Present progressive tense.

Use of present continuous tense

We use the present continuous tense for the following reason

(1) For something that is happening at the moment of speaking:

I am just leaving work. I shall be home in an hour.
Please be quiet. The headmaster is coming.

(2) For something which is happening before and after a given time:

At nine o’clock we are usually having breakfast. 
When I get home the students are doing their homework.

(3) For something which we think is temporary:

Karim is at university. He is studying history.
I am working in Canada for the next two weeks.

(4) For something which is new and contrasts with a previous state:

These days most people are using email instead of writing letters.
What sort of dresses are teenagers wearing nowadays? 
What sort of music are they listening to?

(5) To show that something is changing, growing or developing:

The children are growing quickly.
The world is changing rapidly.
Your English is improving.

(6) For something which happens again and again:

It is always raining in Canada.
Rahim is great. He is always laughing.

Note: We normally use always with this use.

 (7) For something which has been arranged or planned:

Harry is going to a new school next term. 
What are you doing next week?  

The following verbs, on account of their meaning, are not normally used in the continuous form:-

(1) Verbs of perception, e.g., see, hear, smell, notice, recognize.
(2) Verbs of appearing, e.g., appear, look, seem.
(3) Verbs of emotion, e.g., want, wish, desire, feel, like, love, hate, hope, refuse, prefer.
(4) Verbs of thinking, e.g., suppose, believe, agree, consider, trust, remember, and forget.
(5) Have (Possess), own, belong to, contain, consist of etc.

What is Tense?

Read the following sentences:-

1. I write this letter to please you.
2. I wrote this letter to his very presence.
3. I shall write another letter tomorrow.

*In sentence 1, the verb write refers to present time.
*In sentence 2, the verb wrote refers to past time.
*In sentence 3, the verb shall write refers to future time.

Thus a verb may refer

(1) to present time,(2) to past time,(3) to future time.

A verb that refers to present time is said to be in the present Tense; as,

*I write, I love etc.

[The word tense comes from the Latin tempus, time.]

A verb that refers to past time is said to be in the Past Tense; as,

*I wrote, I loved etc.

A verb that refers to future time is said to be in the Future Tense; as,

*I shall write, I shall love etc.

Thus there are three main Tenses

The present, the past, the future.

The tense of a verb shows the time of an action or event.

Note: Sometimes a past tense may refer to present time, and a present tense may express future time; as,

I wish I knew the answer. (Past tense –Present time)
Let’s wait till he comes. (Present tense-Future tense)

Below we give the chief Tenses (Active voice, Indicative mood) of the verb to love.

                                                              Present Tense
Name
Singular Number
Plural Number
1st Person
I love
We love
2nd Person
You love
You love
3rd Person
He loves
They love

                                                              Past Tense
Name
Singular Number
Plural Number
1st Person
I loved
We loved
2nd Person
You loved
You loved
3rd Person
He loved
They loved

                                                              Future Tense            
Name
Singular Number
Plural Number
1st Person
I shall/will love
He shall/will love
2nd Person
You will love
You will love
3rd Person
He will love
They will love

Read these sentences:-

1. I love. (Simple present)
2. I am loving. (Present continuous)
3. I have loved. (Present Perfect)
4. I have been loving. (Present Perfect continuous)

The verbs in all of these sentences refer to the present time, and are therefore said to be in the present tense.

*In sentence 1, however, the Verb shows that the action is mentioned simply, without anything being said about the completeness or incompleteness of the action.
*In sentence 2, the Verb shows that the action is mentioned as incomplete or continuous, that is, as still going on.
*In sentence 3, the Verb shows that the action is mentioned as finished, complete, or perfect, at the time of speaking.
*The tense of the Verb in sentence 4 is said to be Present Perfect Continuous, because the verb shows that the action is going on continuously, and not completed at this present moment.

Thus we see that the Tense of a verb shows not only the time of an action or event, but also the state of an action referred to.

Just as the Present Tense has four forms, the Past Tense also has the following four forms:-

1. I loved. (Simple Past)
2. I was loving. (Past Continuous)
3. I had loved. (Past Perfect)
4. I had been loving. (Past Perfect Continuous)

Similarly the future Tense has the following four forms:-

1. I shall/will love. (Simple future)
2. I shall/will be loving. (Future Continuous)
3. I shall/will have loved. (Future Perfect)
4. I shall have been loving. (Future Perfect Continuous)

We may now define Tense as that form of a Verb which shows the time and the state of an action or event.
