10．I recently spent two years in the Arctic（北极）filming the series（连续剧）Blue Planet．I love being in an environment that hasn't changed for 20，000years．Of course it's freezing，but it must be a healthy place because you never catch a cold．
When I am filming，I like to really feel how lonely the environment is．Filming underwater involves cutting through thick ice．When diving in，you should tie to a line．The person at the other end of the line has to pull you out fast if necessary．
At first I was a research diver for the British Antarctic Survey Project，but for me，science isn't exciting enough．I'd always enjoy photography，and whenever camera teams passed through，they encouraged me to watch and learn．I was then able to move into filming in 1985and have concentrated on Arctic and Antarctic wildlife ever since．
I prefer to be face to face with the animals I'm filming．I haven't been in the water with killer whales yet，but I plan to．Of course，it's dangerous if you choose the wrong moment．．They're big animals and can move fast，so I'd be stupid to film them when they are searching for food!
I have never had problems with polar bears，although once I was frightened when one tried to get into my tent．Polar bears are bold，clever and dangerous．But I made the bear understand I wouldn't hurt it．
Now I come back home，I work in the mornings and spend the afternoons swimming to keep fit．Now I'm fifty，and filming is harder．The challenge（挑战）for me is to go on with the high-quality work．

11．The crab is a living clock．It tells the time of the day by the colour of its skin，which is dark by day and pale by night．The crab's changing skin colour is a regular twenty-four hour cycle（周期）that follows the daily rhythm（循环）of the sun．
    Does the crab really keep time，or is its skin simply affected by the sun's rays（光线），changing colour with the amount of the sunlight？To find out the answer，scientists kept some crabs in a dark room for two months．Even without daylight the crabs'skin colour continued to change．
    The change probably had something with the rhythm of the sun，to help protect the crab from the sunlight and enemies．After millions of years it has become completely regular inside the living body of the crab．
    Scientists noticed that once each day the colour of the crab is especially dark，and that each day this appears about fifty minutes later than the day before．From this they discovered that each crab follows not only the rhythm of the sun but also that of the tides（潮汐）．The crab's darkest period（一段时间）is the time of low tide on the beach where it is caught．
