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. Part 5 can test modal 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.
MTC coaching 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 MTC 7-second choice
Under Part 5 time pressure, a short decision path can help. The 7-second label is an MTC coaching heuristic, not an official TOEIC timing rule.
Pattern one: modal + be + action result
This passive pattern is useful when the focus is the document, shipment, payment, report, application, or request receiving the action rather than the person doing it.
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.
Fast check: if the sentence focuses on the thing receiving the action, check whether the structure needs modal + be + past participle.
MTC quick-decision tool: If the sentence is about a report, file, payment, shipment, application, or request receiving an action, check whether the answer needs modal + be + past participle.
Pattern two: must be, should be, may be, could be
These patterns do different jobs.
Do not choose only because the Japanese translation feels similar. The best answer depends on the business situation, sentence function, and nearby words.
Pattern three: polite requests
Business English uses polite request forms. These are not just grammar points; they also 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 can sound more tentative or polite than can. This is not an absolute rule; the surrounding sentence determines the intended 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: it is easy to see appreciate and search for a complicated grammar rule. An MTC coaching move is to recognise the whole business expression first.
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.
Part 5 can test the structure after these expressions. For example, supposed to and ought to need to. Single modal verbs such as must, should, and may do not take to before the base verb.
Small words around the blank matter
A modal mistake can happen when the learner looks only at the blank. The deciding clue may appear 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. Compliance is mandatory: the safety report ___ be submitted before the inspection begins.
2. To make the request more tentative and polite, ___ you please send the revised invoice by 3 p.m.?
3. The carrier says a delay is possible but not certain: the delivery ___ be delayed because of severe weather.
4. Company policy makes sign-in compulsory: all visitors ___ to sign in at the front desk.
Fast-reader mistake
A common trap is choosing the modal from translation alone. For example, must, should, and have to can feel similar in Japanese. But this kind of Part 5 item is not asking only “What does this word mean?” The function of the sentence matters.
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, reading left to right and translating can make modal verbs feel vague. The decision becomes more systematic when you identify the business function of the sentence.
A request email, company rule, shipping notice, safety instruction, meeting schedule, and apology message can call for different modal patterns. The situation helps narrow the answer.
MTC quick-decision 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-verb items can test business function and tone. Do not only ask, “What does this modal mean?” Ask, “What is the business situation, and what tone does it need?”
Recognising patterns such as must be submitted, may be delayed, could you please, would appreciate, have to, and be supposed to can make modal decisions more systematic and reduce guessing.
