The Present Tense
Simple Present : We use the simple present tense when an action is happening right now, or when it happens regularly (or unceasingly, which is why it’s sometimes called present indefinite).
Depending on the person, the simple present tense is formed by using the root form or by adding -s or -es to the end.
First-person singular: I write every day for an hour. / I feel sorry for his loss.
Second-person singular: You write
Third-person singular: He/she/it writes (note the -s) First-person plural: We write
Second-person plural: You write Third-person plural: They write
Present Perfect Tense : The present perfect tense refers to an action or state that either occurred at an indefinite time in the past (e.g., we have talked before) or began in the past and continued to the present time (e.g., he has grown impatient over the last hour). This tense is formed by have/has + the past participle
Example: I have done my homework Have you had your breakfast?
They have not arrived yet.
He has ruined my project.
Present Continuous Tense: The present continuous verb tense indicates that an action or condition is happening now, frequently, and may continue into the future.
The Present Continuous Formula: to be [am, is, are] + verb [present participle]
I am going for a walk What are you waiting for?
Being a writer is tough.
Is the show still going on?
But… (point to be noted)
I am loving my new job. (incorrect) I love my new job. (correct)
Where are your working these days? (Incorrect) Where do you work these days.? (correct)
Present Perfect Continuous : The present perfect continuous tense (also known as the present perfect progressive tense) shows that something started in the past and is continuing at the present time. The present perfect continuous is formed using the construction has/have been + the present participle (root + -ing).
I have been reading War and Peace since a month now.
I have been living in this house for a month.
Have you been taking your classes lately?
They have been annoying me with loud music since two days.
Not all verbs are compatible with continuous action. Some examples of such verbs are to be, to arrive, and to own.
I have been owning my Mercedes since 2007. (Wrong)
I have owned my Mercedes since 2007. (Present perfect tense)
Geet has been being late for work recently. (wrong)
