TOEIC Modal Verbs Part 2: Passive Forms and Polite Business Tone
This page is Part 2. If you want the basic TOEIC decision map for can, could, should, must, may, might, will, and would, start with the main modal verbs guide first: TOEIC Trap: Modal Verbs in Business Sentences.
This page goes deeper. TOEIC does not only test single modal words. It often tests small business patterns such as must be submitted, may be delayed, could you please, would appreciate, have to, and be supposed to.
Compare these TOEIC-style patterns:
The report must be submitted by Friday.
The delivery may be delayed because of bad weather.
Could you please send the updated invoice?
Employees are supposed to wear identification badges.
Core TOEIC rule: Do not only translate the modal. Check what the business sentence is doing: giving a rule, describing a process, making a polite request, showing uncertainty, or explaining an expected action.
The 7-second choice
In Part 5, you usually do not have time to analyse the whole sentence deeply. Use a faster decision path.
Pattern one: modal + be + action result
TOEIC often uses this pattern when the person doing the action is not important. The focus is on the document, shipment, payment, report, application, or request.
All expense forms must be submitted by the end of the month.
The final schedule should be confirmed before the meeting.
The shipment may be delayed due to heavy traffic.
The issue could be resolved by updating the software.
The fast check is simple: if the sentence focuses on the thing receiving the action, TOEIC often wants be after the modal.
One-second tool: If the sentence is about a report, file, payment, shipment, application, or request, check whether the answer needs modal + be.
Pattern two: must be, should be, may be, could be
These four patterns are common, but they do different jobs.
Do not choose only because the Japanese translation feels similar. In TOEIC, the safest answer usually matches the business situation and the words nearby.
Pattern three: polite requests
TOEIC business English often uses polite request forms. These are not just grammar points. They show workplace tone.
Could you please send the revised file?
Would you mind checking the figures again?
May I speak with the manager?
Would you be able to attend the briefing?
In a direct workplace request, could and would often sound safer than can. But this is not an absolute rule. TOEIC uses the surrounding sentence to show the tone.
Pattern four: would appreciate
This is a common business pattern. It sounds polite because the sentence does not directly command the reader.
We would appreciate your prompt response.
We would appreciate it if you could send the documents by Thursday.
The manager would like to review the proposal before noon.
Fast-reader mistake: some test-takers see appreciate and search for a complicated grammar rule. In TOEIC, the safer move is to recognise the whole business expression.
Pattern five: have to, be supposed to, and ought to
These expressions are close to modal verbs in TOEIC because they show rules, expectations, or advice.
Visitors have to sign in at reception.
Employees are supposed to update their passwords every month.
The team ought to review the safety procedures.
TOEIC may test the small word after the expression. For example, supposed to and ought to need to. Most single modal verbs do not.
Small words around the blank matter
Many modal mistakes happen because the test-taker looks only at the blank. TOEIC often puts the real clue before or after it.
The documents ___ be signed by a supervisor before submission.
Signal: signed by a supervisor → the documents receive the action.
Safer answer: must be / should be / may be, depending on the meaning.
The word after the blank matters. If the next word is be, the question may be testing passive meaning, uncertainty, or future scheduling.
Quick TOEIC check
1. The safety report ___ be submitted before the inspection begins.
2. ___ you please send the revised invoice by 3 p.m.?
3. The delivery ___ be delayed because of severe weather.
4. All visitors ___ to sign in at the front desk.
Fast-reader mistake
The common mistake is choosing the modal from translation alone. For example, must, should, and have to can all feel similar in Japanese. But TOEIC is not asking only “What does this word mean?” It is asking what the sentence is doing.
Bad shortcut: “This sounds necessary, so choose must.”
Better shortcut: “Is this a rule, advice, an expected process, a polite request, or a possible result?”
Why this mistake returns under pressure
Under time pressure, many test-takers read left to right and translate. That makes modal verbs feel vague. The answer becomes easier when you stop translating and look for the business function of the sentence.
A request email, company rule, shipping notice, safety instruction, meeting schedule, and apology message each use different modal patterns. TOEIC hides the answer in that situation.
One-second tool
Ask this: What is this sentence doing?
Rule → must / have to / required to
Advice or expectation → should / be supposed to
Possibility → may / might / could
Polite request → could / would
Business appreciation → would appreciate
Thing receives the action → check for modal + be
Final takeaway
Modal verbs are small, but TOEIC uses them to test business judgement. Do not only ask, “What does this modal mean?” Ask, “What is the business situation, and what tone does it need?”
If you can recognise must be submitted, may be delayed, could you please, would appreciate, have to, and be supposed to, you will handle many modal questions faster and with less guessing.
