Final answer:
Use the 'may I' phrase to formally request permission for services, emphasizing courtesy and respect. Statements like 'May I have access to...' are suitable for services that are non-excludable and do not charge for use.
Step-by-step explanation:
When you wish to ask for permission in a courteous and formal way, using the expression 'may I' is highly appropriate. For instance, you might say 'May I have the privilege of accessing the library's resources?' or 'May I request the assistance of a tutor?' In these cases, you are kindly asking for a specific service and demonstrating respect at the same time.
In the context of your references, to use the 'may I' expression for accessing services that are non-excludable, you might formulate your request by stating 'May I participate in this community service program?' or 'May I attend the public lecture being held at the town hall?' Notice how the subjunctive mood is subtly present in these queries, expressing a desire for permission rather than stating an immediate action.
To ask for permission to get different services, you can use the expression 'may I'. For example, you can say 'May I bring a friend?' or 'May I use the computer?'. Using this expression shows that you are politely asking for permission. It is important to note that the subjunctive mood is often used when expressing wishes or making requests. The subjunctive mood is used to state hypothetical or unlikely scenarios. In the given conversation between Mrs. Walker and Mrs. Miller, Mrs. Walker gives permission for Mrs. Miller to bring her friend.
