1.動詞B1
釋義

將會

第一人稱未來式，正式用語

used with 'I' or 'we' to talk about something that you expect to happen in the future; in modern everyday English, 'will' is much more common than 'shall' for this meaning, even with first-person subjects

例句

I shall be sixty years old next spring, so I plan to retire soon.

我明年春天就六十歲了，所以我打算不久後退休。

shall with first-person for simple future prediction

We shall notify all customers by email if there are any delays.

若有任何延誤，我們將會以電子郵件通知所有客戶。

同義詞
  • will

    the standard choice for simple future with all subjects; less formal than 'shall'

文法句型

I/we + shall + base verb

用法筆記

In modern British English, 'will' has largely replaced 'shall' for simple future even after I/we. Using 'shall' in this sense makes your speech sound quite formal or old-fashioned. American English rarely uses 'shall' for the future at all.

常見錯誤

❌He shall arrive at the airport by noon.
✅He will arrive at the airport by noon.
💡'Shall' for simple future only works with 'I' or 'we'; use 'will' with other subjects.
❌I shall be there — I already bought the ticket.
✅I will be there
💡I already bought the ticket.' — For a casual, everyday statement about the future, 'will' sounds more natural than 'shall'.

2.動詞A2
釋義

要…嗎

提出建議或徵求對方意願

used in questions with 'I' or 'we' to ask someone if they agree with a suggestion, want you to do something for them, or want to do something together

例句

我幫大家泡點茶，一邊等其他人好嗎？

Shall I ...? for offering to do something

Shall we take a short break and continue after lunch?

我們先休息一下，吃完午餐再繼續好嗎？

Shall we ...? for making a joint suggestion

同義詞
  • should

    in 'Should we...?' questions, similar meaning but implies weaker suggestion or asks for advice

  • let's

    not a question form; 'Let's go' is a direct suggestion, while 'Shall we go?' invites agreement

文法句型

Shall + I/we + base verb + ...?

用法筆記

This is the most common and natural use of 'shall' in modern English, used across both British and American varieties. 'Shall I' offers to do something for the listener; 'Shall we' suggests an activity involving both speaker and listener. There is no other modal verb that performs exactly this function.

常見錯誤

❌Shall you come to the party?
✅Will you come to the party?' or 'Are you coming to the party?
💡'Shall' in questions is only used with 'I' and 'we'; use 'will' for questions with 'you'.
❌Shall we to go now?
✅Shall we go now?
💡After 'shall', use the base form of the verb without 'to'.

3. used to express a strong intention or to insist that something must happen, espe

3.動詞B2
釋義

一定；絕不

表達強烈意志或不容置疑的決心

used to express a strong intention or to insist that something must happen, especially when someone else disagrees with or doubts the outcome

例句

No matter how hard they try, they shall not stop us from speaking the truth.

不論他們多麼努力，都休想阻止我們說出真相。

shall not for emphatic refusal or resistance

You shall get a fair hearing — I promise to listen to both sides.

你一定會得到公平的申訴機會——我保證會聽取雙方的意見。

同義詞
  • must

    stronger in obligation; 'shall' focuses on the speaker's determination, while 'must' focuses on necessity

  • will

    when stressed, 'will' can also express determination, but 'shall' sounds more formal and forceful

文法句型

subject + SHALL + base verb (stressed)

用法筆記

When used this way, 'shall' is usually stressed (spoken more loudly) in speech. This sense overlaps with the LEGAL OBLIGATION sense in writing — the key difference is that determination carries emotional force, while legal obligation is neutral and procedural. With second- and third-person subjects (you, he, she, they), this sense sounds very strong and almost like a command or prophecy.

常見錯誤

❌You shall be late if you do not hurry.' (meaning a simple prediction)
✅You will be late if you do not hurry.
💡For predictions about what will happen, use 'will'. 'Shall' for determination expresses the speaker's strong will, not a prediction.
❌The weather shall be sunny tomorrow.
✅The weather will be sunny tomorrow.
💡Weather forecasts use 'will', not 'shall', because there is no element of personal determination.

4.動詞B2
釋義

應；須

法律或正式文件中表示強制義務

used in official documents, contracts, and regulations to state that something is required by law or by a specific set of rules; closest in meaning to 'must' but even more formal

例句

Each tenant shall pay rent on or before the fifth day of the month.

每位承租人應於每月五日或之前支付租金。

shall in legal contracts for mandatory action

All staff shall wear protective gloves when handling any chemical substances.

所有工作人員處理任何化學物質時應穿戴防護手套。

同義詞
  • must

    the more common choice for expressing obligation in both spoken and written English; many legal drafters now prefer 'must' for clarity

  • be required to

    very formal and explicit about obligation; common in official documents

文法句型

subject + shall + base verb

用法筆記

In legal and official writing, 'shall' creates a binding duty or requirement. Many modern legal style guides (especially in the United States) now recommend replacing 'shall' with 'must' to avoid confusion, since 'shall' can also express future time or prediction. In everyday rules and instructions, use 'must' instead.

常見錯誤

❌Students shall bring their textbooks to class tomorrow.' (in a casual classroom)
✅Students must bring their textbooks to class tomorrow.
💡For everyday school or workplace rules, 'must' sounds more natural than 'shall'.
❌I shall finish this report by Friday.' (when you just mean you plan to)
✅I will finish this report by Friday.' or 'I must finish this report by Friday.
💡Using 'shall' in an everyday context sounds either legalistic or overly dramatic.
