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.

'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.

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.

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.
