Why Tenses Decide Accuracy (কেন গুরুত্বপূর্ণ)
Tense errors are one of the most visible things an examiner sees, and every IELTS module uses tenses differently: past simple for finished Task 1 data, present simple for facts and general Task 2 truths, present perfect for recent change, and narrative tenses for Speaking Part 2 stories. A wide, accurate tense range is core to Band 7 "Grammatical Range & Accuracy".
কালের ভুল পরীক্ষকের চোখে সবচেয়ে স্পষ্ট, আর প্রতিটি IELTS মডিউলে কাল আলাদাভাবে ব্যবহৃত হয়: শেষ হওয়া Task 1 উপাত্তে past simple, সাধারণ সত্যে present simple, সাম্প্রতিক পরিবর্তনে present perfect, Speaking Part 2 গল্পে narrative tense।
Two ideas run every tense: time (past / present / future) and aspect (simple = a whole event; continuous = in progress; perfect = looking back from a later point). Choose the time, then the aspect.
প্রতিটি কালে দুটি বিষয়: সময় ও aspect (simple = সম্পূর্ণ ঘটনা; continuous = চলমান; perfect = পরের বিন্দু থেকে পিছনে তাকানো)।
Part of the Band 7+ grammar series. See the full index on the Grammar hub.
The Tense System (কালের কাঠামো)
Aspect is easiest to see on a timeline: where the action sits relative to "now" or to another point. Aspect টাইমলাইনে বোঝা সহজ: ক্রিয়াটি "এখন" বা অন্য বিন্দুর সাপেক্ষে কোথায়।
| Aspect | Past | Present | Future |
|---|---|---|---|
| Simple | rose / worked | rises / works | will rise |
| Continuous | was rising | is rising | will be rising |
| Perfect | had risen | has risen | will have risen |
| Perfect continuous | had been rising | has been rising | will have been rising |
Present Tenses (বর্তমান কাল)
| Tense | Use it for | IELTS example |
|---|---|---|
| Present simple | facts, general truths, habits, the graph itself | The chart shows data for five countries. · Education reduces poverty. |
| Present continuous | now / temporary / a current trend | Cities are becoming more congested. · I am studying for IELTS. |
| Present perfect | past action, present result; recent change; "so far" | The government has introduced new policies. · I have lived here for ten years. |
| Present perfect continuous | an action continuing up to now (duration) | Scientists have been studying the genome for decades. |
Stative verbs are NOT used in the continuous: know believe understand want need contain belong seem prefer. Say "I understand", not "I am understanding".
Stative verb continuous-এ হয় না: "I understand" ঠিক, "I am understanding" ভুল।
Past & Narrative Tenses (অতীত ও বর্ণনামূলক)
Task 1 with a date and Speaking Part 2 stories both need the past. To narrate well, combine three tenses. তারিখযুক্ত Task 1 ও Speaking Part 2 গল্পে অতীত লাগে। ভালো বর্ণনায় তিনটি কাল মেশান।
| Tense | Use it for | Example |
|---|---|---|
| Past simple | a finished action / the main events | The airport opened in 1998. · Last year I visited Cox's Bazar. |
| Past continuous | the background / an action in progress | While we were walking on the beach, it started to rain. |
| Past perfect | an earlier past — before another past action | By the time I arrived, the tour had already left. |
| used to / would | past habits no longer true | Cities used to be built for horses. · As a child I would read every night. |
Future Forms (ভবিষ্যৎ)
English has several futures; the one you choose shows your meaning. Essential for Task 2 predictions and Speaking Part 3. ইংরেজিতে একাধিক ভবিষ্যৎ; কোনটি বাছবেন তা অর্থ বোঝায়।
| Form | Meaning | Example |
|---|---|---|
| will + verb | prediction, fact, instant decision | Automation will change the workplace. |
| be going to | a plan / evidence now | The government is going to invest in railways. |
| present continuous | a fixed arrangement | I am taking the test next month. |
| present simple | timetables / after "when, if, before" | The plane leaves at 9. · When I finish, I will call you. |
| future continuous | in progress at a future time | By 2050, most people will be using electric cars. |
| future perfect | completed before a future point | By 2030, the project will have been completed. |
| is likely / expected to | hedged prediction (Band 7+) | Sea levels are likely to rise further. |
Present Perfect vs Past Simple (ক্লাসিক বিভ্রান্তি)
This is the most common tense error at Band 6. The rule: use past simple with a finished time; use present perfect when the time is unfinished or unstated and the result matters now. Band 6-এর সবচেয়ে সাধারণ ভুল। নিয়ম: শেষ হওয়া সময়ে past simple; সময় অসমাপ্ত/অনুল্লেখিত ও ফল এখন থাকলে present perfect।
| Past simple (finished time) | Present perfect (up to now) |
|---|---|
| Prices rose in 2010. | Prices have risen recently / since 2010. |
| I visited London last year. | I have visited London (at some point). |
| The company launched it in May. | The company has just launched it. |
Time-word clues: past simple → yesterday, in 1998, last year, ago, when I was young. Present perfect → already, yet, just, ever, never, so far, recently, since, for (up to now).
সময়-শব্দ ইঙ্গিত: ago/last year → past simple; already/yet/since/for → present perfect।
