Dereck and Beverly are wildlife animal filmmakers(电影制片人). They have made lots of films about animals and plants.
Their job is to keep and protect the big cats of Africa from damage(伤害). Beverly also takes photos of the lions and her pictures have appeared in National Geographic magazines.
When they were kids, Dereck was quiet and healthy, he was good at math and science. Beverly had a twin brother. At that time, her brother and she often got their mother into trouble! Beverly was a dancer, an athlete, played the piano (not very well), and was a class leader. Her favourite subject was science and she always got excellent grades in her science exams.
When in the field, their work starts at around 4 am. After drinking a cup of tea, they drive out into a bush(灌木丛)to find their subjects. Sometimes that is a lion pride(群). Lions are family animals, they usually live in groups of 15 or more. Sometimes that is a single leopard(花豹). They follow the animals for the day, filming, researching, and collecting facts, information or pictures. They don't stop working even when they have lunch. They are often back in camp by 8 pm.
When talking about the favourite places to explore, Dereck says, “We live in it!” Beverly thinks being in nature is her favourite. Dereck thinks running or taking a swim in the Okavango swamp(沼泽)—especially swimming close to crocodile(鳄鱼)is great fun, but Beverly says, "Swimming is fun but crazy in these waters."
