This is a personal assignment that only you can complete. However, we can provide some guidance to help you. This is an example of a letter with these specifications:
<em>Dear Minister of Transport,</em>
<em>I understand that your time is spent looking for ways to ensure that people have effective, efficient and reliable transportation so that they can conduct their lives in the way they desire. However, I believe that using cars is not the right way to ensure this. I think that all city centres should be car-free, in order to allow people to walk and cycle easily. It is a known fact that many accidents occur in cars, and that these often affect young people who do not have much experience driving. Moreover, cars can cause both noise and air pollution, decreasing the quality of live of people who live in the centre, as well as those who visit it. These are enough reasons to ban cars as soon as possible, and I am sure that you will consider this in your future projects.</em>
<em>Thank you for your time,</em>
<em>John Smith</em>
A speaker addresses a person for various reasons. For example, s/he may see that the listener is distracted and s/he may want the addressee to focus more on what s/he has to say. Moreover, it can happen in the middle of a speech, because what will follow is really important and s/he feels the need to underline it by asking for more attention from the listeners. Furthermore, the speaker may address a person because s/he may want to talk specifically to this person about something or in order to give him/her the stand.
So, from all the above, it could be concluded that the basic request of the speaker when s/he addresses a person is to grab the listener's attention.
