(i) Use a range of modal verbs, e.g. could, might and also other expressions, such as Would you mind explaining?, in order to ask for something, ask permission, or ask someone to do something
Would you mind passing me my book?
You don't mind asking her, do you?
(ii) Recognise that with expressions using mind the appropriate way of agreeing to the request is usually no, rather than yes
(iii) Vary register in different situations and relationships
Example: Is it okay if I talk to the boss about it?
Would it be possible for me to speak to the Principal?
Choose appropriate intonation to indicate, e.g. politeness or assertiveness
(iv) Make requests indirectly, where appropriate, and introduce a request with a pre-request, particularly when a request is for something difficult to ask for
Example: I'm really sorry to bother you, but... I wonder if I could ask you a favour?
(v) Use appropriate phrases, including pre-request phrases, when making requests by telephone
