Read the text "A life with dolphins".

dolphins-g6f21cd748_1920.jpg

Dr Jonathan Casey has a very busy lifestyle. He is a teacher, a tour guide and an author, all at the same time. Jonathan is from England, but he lives in the USA and works at the Dolphin Centre in Florida. He spends all his time with his favourite animals, dolphins.

At the centre, Jonathan works from 9 o’clock in the morning until 7 o’clock in the evening. He teaches visitors all about dolphins – where they live, what they eat and what they can do.

He also takes people on trips to swim with dolphins in the sea at the weekends. Jonathan loves to be in the water with the dolphins and touch their long bodies and their big tails.

Jonathan also writes books about dolphins. There are lots of different types of dolphins. They are grey, black and brown ones that live in seas and oceans. There are also pink dolphins that live in rivers in South America and Asia.

Jonathan likes the way he lives. ‘Dolphins are my life. I like to be with them and to help other people learn about these beautiful animals”, he says.

Write correct or incorrect:

1. Casey spends all his time with dolphins.

2. Jonathan works from 9 o’clock.

3. Jonathan likes the way he lives.
