Tense is the form taken by a verb to indicate time and continuance or completeness of action. The continuance or completeness of action is denoted by four subcategories.

Continuous Tense: The action is incomplete or continuous or going on.
Perfect Tense: The action is complete, finished, or perfect with respect to a certain point of time.

3. To express changing or developing situations.

4. For an action that is planned or arranged to take place in the near future.
I am going to cinema tonight.
Note: But it is not good to use the present continuous for slightly distant future. So, don’t say “I am going to cinema next week.”
Rather, use the future simple. So, it is better if you say “I will go to the cinema next week.”
5. When the reference is to a particularly obstinate habit, the present continuous is used instead of present simple. An adverb like always, continually, constantly is also used.
It is no use scolding him; he always does what is forbidden. (Incorrect)
Note: that his doing what is forbidden has become a die-hard habit. The habit persists in spite of advice or warning. So, we should use the present continuous.
It is no use scolding him; he is always doing what is forbidden. (Correct)
Uses of Present Perfect Tense
Verb Forms: Has / have + third form of verb
1. To indicate the completed activities in the immediate past.
He has just gone out.
2. Action completed in the immediate past or an action of the past whose effect lingers in the present.
I wrote three books. (Incorrect)
The given sentence appears to be incomplete. The reader of the sentence immediately queries- “When did you write three books?” It would be a different case if you said
I wrote books.
Then the reader would infer that you wrote books in the past as a profession or hobby. But when you are being so specific as to say “three books”, we immediately feel the need of a time frame.
Since no time frame is mentioned, we assume it to be ‘by now’. So, we have something to the effect.
I have written three books by now.
This ‘by now’ is implied and need not be written.
So, for example:
I have written three books. (Correct)
3. The present perfect is never used with adverbs of past time. In such cases, the past simple should be used.
India has won the match last week (Incorrect)
“Last week” is not immediate past. You may therefore be tempted to use the present perfect. But remember that the immediate past here does not go unindicated. Last week is being used as an adverb of past time.
So, For example:
India won the match last week. (Correct)
4. To express past actions whose time is not given and not definite – actions with their effect continuing in the present.
I have never known him to be angry.
Have you read ‘Gulliver’s Travels’?
5. To describe the past events when we think more of their effect in the present than of the action itself.
I have cut my finger.
6. For long actions and situations which started in the near past and went on until very recently.
