TOEIC® सहायक क्रियाएँ: Perfect Modals, व्यावसायिक ईमेल और जाल
TOEIC® Part 5 के लिए सभी 9 सहायक क्रियाएँ: संभावना पैमाना, perfect modals, व्यावसायिक ईमेल पैटर्न, semi-modals और शीर्ष 5 जाल।
Modal Verbs: Key to TOEIC® Part 5
Modal verbs (can, could, may, might, will, would, shall, should, must) are auxiliary verbs that modify the meaning of the main verb. They express ability, permission, obligation, advice, or probability. On the TOEIC®, they account for roughly 15-20% of Part 5 questions and appear regularly in Part 6 emails.
Their grammar rules are strict: no -s in the third person, base infinitive without to, no infinitive or participle forms. Mastering these rules is a quick point gain in your TOEIC préparation.
Quick Reference Table
All 9 pure modals organized by primary function:
| Modal | Primary function | TOEIC® Example |
|---|---|---|
| can | ability / informal permission | She can process 50 orders per hour. |
| could | past ability / politeness | Could you forward the attachment? |
| may | formal permission / possibility | Employees may request a transfer. |
| might | weaker possibility | The shipment might be delayed. |
| will | future / willingness | The board will announce the results. |
| would | conditional / politeness | Would you like to reschedule? |
| shall | contractual obligation | The tenant shall maintain the property. |
| should | advice / recommendation | You should review the contract first. |
| must | obligation / certainty | All visitors must sign in at reception. |
Probability and Deduction
The certainty scale from most to least certain:
| Modal | Degree | Example |
|---|---|---|
| must | ~95% (near certainty) | She must be in the office by now. |
| will | ~90% (prédiction) | The package will arrive tomorrow. |
| should | ~75% (reasonable expectation) | The report should be ready by noon. |
| may | ~50% (likely possibility) | The shipment may arrive tomorrow. |
| might / could | ~30% (weaker possibility) | The delay could cause problems. |
| can't | ~0% (logical impossibility) | That can't be the right answer. |
Perfect Modals (modal + have + past participle)
Perfect modals are essential for talking about past actions. They appear regularly in TOEIC® Parts 5 and 6, and are often combined with the passive voice:
| Perfect modal | Meaning | Example |
|---|---|---|
| should have + PP | should have done (regret) | You should have submitted the form earlier. |
| could have + PP | could have done (unrealized) | We could have finished the project on time. |
| must have + PP | must have done (past déduction) | She must have left the office already. |
| may/might have + PP | may have done (past possibility) | The package may have been delivered. |
| would have + PP | would have done (past conditional) | I would have called, but I lost your number. |

Top 5 TOEIC® Traps
- Must vs have to: must for personal obligation, have to for external obligation. In the past, only had to is correct
- Can vs may: can for ability or informal permission, may for formal permission or possibility
- Should vs must: should is advice, must is obligation
- Would vs will: would for conditional and politeness, will for certain future
- No double modals: you never say *will can. Use will be able to instead
