Sheep /iː/. /iː/ is a long sound. Make your mouth wide, like a smile. Your tongue touches the sides of your teeth. (agree, seat, team, pizza, Peter.) Ship /ɪ/. /ɪ/ is a short sound. Make you mouth a bit less wide than for /i:/. Your tongue is a bit further back in your mouth than for /i:/. (if, listen, miss, dinner, swim, building.)

You will need a cassette or CD player to listen to the recordings. It will be useful if you can record your own voice, so that you can listen to your own pronunciation and hear your progress. When you are studying individual sounds it's sometimes useful to have mirror, so that you can see the shape of your mouth. When you are working with the recordings, you should replay a track as often as you need to. Intonation patterns in phrases and sentences are very important. The best way to work on pronunciation is 'little and often'.
