SECTION 3 — TENSE & TIME (Concepts 32–48)

32. Present perfect is used with "since" (a point in time) and "for" (a duration)

• Wrong: I am living in Pune since 2019.
• Fix: I have been living in Pune since 2019.
• Wrong: She is working at this branch for six years.
• Fix: She has been working at this branch for six years.
• Wrong: They are associated with this NGO since its founding.
• Fix: They have been associated with this NGO since its founding.

33. Past tense (not present perfect) is used with a specific past time reference

• Wrong: I have visited Goa last December.
• Fix: I visited Goa last December.
• Wrong: He has submitted the report yesterday evening.
• Fix: He submitted the report yesterday evening.
• Wrong: She has cleared the entrance exam in 2021.
• Fix: She cleared the entrance exam in 2021. Why this happens: both tenses describe something that happened before now, so the two feel interchangeable — but present perfect is reserved for actions with no fixed past time attached (or one that's still relevant), while any word pinning the action to a specific past moment (yesterday, last December, in 2019) forces simple past instead.

34. Past perfect is used for the earlier of two past actions

• Wrong: When I reached the station, the train left.
• Fix: When I reached the station, the train had left.
• Wrong: The clerk realised he lost the receipt after the customer left.
• Fix: The clerk realised he had lost the receipt after the customer left.
• Wrong: By the time the doctor arrived, the patient's condition worsened considerably.
• Fix: By the time the doctor arrived, the patient's condition had worsened considerably.

35. "If" clauses (Type II, unreal present): if + past simple, would + base verb

• Wrong: If I was you, I would accept the offer.
• Fix: If I were you, I would accept the offer.
• Wrong: If he was more punctual, he would not miss deadlines.
• Fix: If he were more punctual, he would not miss deadlines.
• Wrong: If the branch was closer to my house, I would visit more often.
• Fix: If the branch were closer to my house, I would visit more often.

36. "If" clauses (Type III, unreal past): if + past perfect, would have + past participle

• Wrong: If she had studied harder, she will pass the exam.
• Fix: If she had studied harder, she would have passed the exam.
• Wrong: If the officer had checked the file, the error would not happened.
• Fix: If the officer had checked the file, the error would not have happened.
• Wrong: If they had booked earlier, the tickets would not been so expensive.
• Fix: If they had booked earlier, the tickets would not have been so expensive.

37. "Wish" statements about the present take the past subjunctive

• Wrong: I wish I am taller.
• Fix: I wish I were taller.
• Wrong: She wishes she has more time to prepare for the interview.
• Fix: She wishes she had more time to prepare for the interview.
• Wrong: He wishes he is posted in his hometown.
• Fix: He wishes he were posted in his hometown.

38. "By the time" + a future clause pairs with the future perfect

• Wrong: By the time you arrive, I will finish the report.
• Fix: By the time you arrive, I will have finished the report.
• Wrong: By the time the results are declared, the batch will complete its training.
• Fix: By the time the results are declared, the batch will have completed its training.
• Wrong: By the time the auditors reach, we will close all the pending files.
• Fix: By the time the auditors reach, we will have closed all the pending files.

39. Stative verbs (think, believe, own, possess, know, love, seem, appear, want, prefer) don't take the continuous form

• Wrong: I am knowing the answer to this question.
• Fix: I know the answer to this question.
• Wrong: She is preferring tea over coffee these days.
• Fix: She prefers tea over coffee these days.
• Wrong: He is owning three properties in this locality.
• Fix: He owns three properties in this locality. Why this happens: the continuous form ("-ing") is meant to show an action in progress, but stative verbs describe a mental state, a relationship, or a permanent fact rather than an ongoing activity — a state can't really be "in progress" the way an action can.

40. Reported speech shifts present to past, and "will" to "would," unless the fact is a universal truth

• Wrong: He said that the earth revolved around the sun.
• Fix: He said that the earth revolves around the sun.
• Wrong: The teacher told the class that water boil at 100 degrees Celsius.
• Fix: The teacher told the class that water boils at 100 degrees Celsius.
• Wrong: She mentioned that honesty were the best policy.
• Fix: She mentioned that honesty is the best policy.

41. Sequence of tenses: if the main clause is past, the subordinate clause generally stays past too

• Wrong: She told me that she is arriving tomorrow.
• Fix: She told me that she was arriving the next day.
• Wrong: He informed the panel that he will submit the documents by Friday.
• Fix: He informed the panel that he would submit the documents by Friday.
• Wrong: The clerk mentioned that the file is already dispatched.
• Fix: The clerk mentioned that the file was already dispatched.

42. "Used to" + base verb for a discontinued past habit

• Wrong: I used to playing cricket every evening as a child.
• Fix: I used to play cricket every evening as a child.
• Wrong: He used to travelling by train before he bought a car.
• Fix: He used to travel by train before he bought a car.
• Wrong: She used to working night shifts before her promotion.
• Fix: She used to work night shifts before her promotion.

43. "Be used to" + gerund for a present or past habit of familiarity

• Wrong: After years abroad, she is used to drive on the left.
• Fix: After years abroad, she is used to driving on the left.
• Wrong: New recruits are not used to work under such strict deadlines.
• Fix: New recruits are not used to working under such strict deadlines.
• Wrong: He was not used to wake up so early for the morning shift.
• Fix: He was not used to waking up so early for the morning shift. Why this happens: "used to" (habit that stopped) and "be used to" (accustomed to) look almost identical but behave differently — the first is always followed by a base verb, the second always by "-ing," and learners blend the two patterns because the words "used to" appear in both.

44. Future in the past: "was/were going to" for an unfulfilled past plan

• Wrong: I am going to call you yesterday, but I forgot.
• Fix: I was going to call you yesterday, but I forgot.
• Wrong: We are going to submit the proposal last week, but the printer broke down.
• Fix: We were going to submit the proposal last week, but the printer broke down.
• Wrong: She is going to attend the seminar last month, but she fell ill.
• Fix: She was going to attend the seminar last month, but she fell ill.

45. Time clauses with "when," "as soon as," "until," "before," "after," "once" use present tense to refer to future time

• Wrong: I will let you know as soon as I will receive the confirmation.
• Fix: I will let you know as soon as I receive the confirmation.
• Wrong: She will not sign the form until she will read every clause.
• Fix: She will not sign the form until she reads every clause.
• Wrong: We will start the ceremony once the chief guest will arrive.
• Fix: We will start the ceremony once the chief guest arrives.

46. Present continuous for fixed future arrangements, not "will"

• Wrong: I will meet the client tomorrow at 10 — it's already scheduled.
• Fix (preferred for a fixed plan): I am meeting the client tomorrow at 10.
• Wrong: He will join the new department from next Monday, as confirmed by HR.
• Fix: He is joining the new department from next Monday, as confirmed by HR.
• Wrong: We will shift to the new office next week, as already notified.
• Fix: We are shifting to the new office next week, as already notified.

47. Simple present for scheduled/timetabled events, even when the event is in the future

• Wrong: The train will leave at 6 p.m. sharp, according to the timetable. (grammatically fine, but exams often test the timetable form:)
• Fix (preferred for a timetable): The train leaves at 6 p.m. sharp, according to the timetable.
• Wrong: The exam will start at 10 a.m. as per the official notice.
• Fix: The exam starts at 10 a.m. as per the official notice.
• Wrong: The bank will open at 9:30 a.m. on all working days.
• Fix: The bank opens at 9:30 a.m. on all working days.

48. Present perfect continuous shows an action that started in the past and is still continuing, with emphasis on duration

• Wrong: He is working on this project since morning.
• Fix: He has been working on this project since morning.
• Wrong: They are waiting outside the office for two hours.
• Fix: They have been waiting outside the office for two hours.

Answer Key

1. "has joined" → "joined" (specific past time reference, "three years ago")
2. "was" → "had been" (Type III unreal past needs past perfect)
3. "will finish" → "will have finished" (future perfect with "by the time")
4. "am understanding" → "understand" ("understand" is a stative verb)
5. "will" → "would" (backshift in reported speech)
6. "are living" → "have been living" (present perfect continuous with "since")
7. "have" → "had" ("wish" takes the past subjunctive)
8. "used to working" → "used to work" (base verb after "used to")
9. "will be confirmed" → "is confirmed" (present tense in a future time clause)
10. "is knowing" → "knows" ("know" is a stative verb)
