Kevin might be heavily involved in his sport, in fact he might be a natural leader and become the captain of the football team, so for Kevin typical communication would involve:
The pep-talk. In this case the coach/captain will do most of the talking, he will usually ask questions which the team answers. This includes:
The instructions from the sideline during play. In this case, only the coach/captain would be talking and he might be calling out loudly from the sideline or from the field so the players can hear him. These instructions might include:
The dialogue between players. This sort of talk usually involves one speaker, the listener would be expected to react (eg, by passing the ball) rather than provide an answer. It might include:
The encouragement from the spectators. In this case it would only be the spectators who are speaking. They might be directing their speech to the players who are not expected to respond. This includes:
Finally, what can be said about Kevin's communicative needs? Kevin is not likely to use formal speech very much in his day to day work, but he will need to have good oral communication skills to be able to negotiate the prices of land, vehicles, fertilizer, livestock, fencing materials, etc. He will need to be able to hire and fire subcontractors. He will need to explain contractral arrangements, organise the delivery of fertilizer or the collection of lifestock to be taken to the sale yards, etc. In his day to day work, Kevin will develop a special set of vocabulary or farming terminology. He might need to develop and substantiate a good argument to convince his father to change his farming practices.
Kevin will need further language skills in his social and sporting activities. He will want to identify with the group so will use the same expressions and expletives as his mates do. As captain of the football team he may need to articulate his decisions, negotiate objections to them, give praise, sympathy, and advice. He might even want to chat up a girl! In fact if Kevin's lifestyle is as we imagine it, he will need a very broad range of oral language skills.
