  • Singular Subject – Singular verb
  • plural subject – plural verb

Example: i) Mahei is a meritorious student. ii) Vehicles create traffic jam.

Rule-2: After a preposition, the verb will take -ing:

Preposition: (in, at, on, of, for, from, by, with, without, before, after, into, across, about, to, among, over, under, between, behind etc. ) + noun / (verb + ing.)

Example: i) Television is an important source of entertainment or entertaining. ii) Children are fond of using mobile phone.

Rule-4:

Example: i) I am Sohel. ii) He is driving a car. iii) We are going home. iv) They have won the game. v) He has eater rice.

Rule-5: After the modal auxiliary verb, the base form of verbs will be used:

After Modal auxiliary verb (Can, Could, may, might, shall, should, will, would, must, used to, have to, need, dare, ought to) + V1 (base form of the verb)

Example: i) We need to be more conscious about Covid-19 ii) Can I please borrow your pen? iii) Police must do their duties wearing PPE. iv) We should stat home and maintain social distancing.

Rule-6: After some phrases, we use the present progressive tense:

If a sentence contains (now, at this moment, at present, day by day, increasingly, rapidly, gradually)  present continuous tense will be used.

Example: i) Why are doing your homework at this moment. ii) Corona virus is spreading rapidly at present.

Rule-7: After some phrases, we use the simple past tense:

If we get (yesterday, one day ago, once, last, after a few days, last night, once upon a time, in the past, previously) in a sentence, past Indefinite Tense will be used.

Example: i) Once upon a time, there was a man named Adu Vai who failed in class vii seven times. ii) Forty people died in Covid-19 one day ago.

Rule-8: After some phrases, we use the present perfect tense:

If we get (just, just now, already, yet, ever, lately, recently, immediately) in a sentence, present perfect tense will be used.

Example: i) This car has imported from Japan recently. ii) We have taken her to the hospital immediately after the accident.

Rule-9: mind, worth, without, get used to + V1 -ing

1. You had better do the work right now. 2. We would rather help the farmer of our region.

Rule-11: It is time, It is high time, wish, fancy – past indefinite

If we get (it is time, it is high time, wish, fancy) in a sentence, the tense of the sentence will be past indefinite tense.

Example: i) I fancy I turned pale. ii) It is high time we developed our country. iii) It is time we took our preparation for the exam.

If a sentence contains lest, the other part will take ‘should’ after the subject.

Example: i) Walk fast lest you should miss the train. ii) Read attentively lest you should fail in the exam. iii) Work hard lest you should fail in the exam.

Rule-13: If, wish, as if, as though – unreal past = were

If a sentence contains (if, wish, as if, as though), the verb will be unreal past. That means after subjects we have to use ‘were’.

Example: i) If I were a doctor, I could treat the poor. ii) I wish I were a king. iii) If I were an engineer, I could innovate new things. iv) He talks as if he were insane.

Rule14: Present Indefinite / present perfect tense + since + past Indefinite tense

If a sentence contains since in the middle and the 1st part is present indefinite tense or present perfect tense, the other part will be past indefinite tense.

Rule-15:past indefinite tense + since + past perfect tense.

If a sentence contains since in the middle and the 1st part is past indefinite tense, the other part will be past perfect tense.
