Article: Film director James Cameron first became interested in sea exploration when he was a little boy.His love for the ocean grew after he made the 1989 undersea adventure film The Abyss and the 1997 blockbuster Titanic,one of the most successful movies of all time.Following that big success,James Cameron decided to put his film career on hold to become an explorer. In 2012,James Cameron made a journey to the deepest spot in the Mariana Trench,known as Challenger Deep.And now the great journey has been made into a documentary film,named James Cameron's Deep-sea Challenger 3D. In James Cameron's fantasy films,such as Avatar and The Abyss,the unexplored areas are decorated in colors and full of danger.But on his dive into Challenger Deep,the reality proved far different: white, deserted and dull. "I felt like I had gone to another planet,"Cameron said after returning from the cold and dark place in the Western Pacific Ocean,nearly 7 miles below the surface."I really have a sense of being separated and realize how tiny I am down in this big, black and unexplored place." Cameron captured the moon-like landscape of the deep sea and documented the sea creatures he observed in the ocean. James Cameron's Deep--sea Challenger 3D tells the story of Cameron' s journey.It is a film about determination,danger and the ocean'S greatest depths.The movie shows a unique insight into Cameron's world when he makes his dream reality and makes history by becoming the first person to travel alone to the deepest point on the planet. It's an exciting film and inspiring reminder that our beautiful planet still has a lot to explore.
Answer: When he was in his childhood.
When did James Cameron become interested in the ocean?

Article: Women are friendly. But men are more competitive. Why? Researchers have found it's all down to the hormone oxytocin . Although known as the love hormone, it affects the sexes differently. "Women tend to be social in their behavior. They often share with others. But men tend to be competitive. They are trying to improve their social status," said Professor Ryan. Generally, people believe that the hormone exytocin is let out in our body in various social situations and our body creates a large amount of it during positive social interaction such as falling in love or giving birth. But in a previous experiment Professor Ryan found that the hormone is also let out in our body during negative social interactions such as envy. Further researches showed that in men the hormone oxytocin improves the ability to recognize competitive relationships, but in women it raises the ability to recognize friendship. Professor Ryan's recent experiment used 62 men and women aged 20 to 37. Half of the participants received oxytocin. The other half received placebo . [( )] [( :Love my Dog.)] After a week, the two groups switched with participants. They went through the same procedure with the other material. Following each treatment, they were shown some video pictures with different social interactions. Then they were asked to analyze the relationships by answering some questions. The questions were about telling friendship from competition. And their answers should be based on gestures, body language and facial expressions. The results indicated that, after treatment with oxytocin, men's ability to correctly recognize competitive relationships improved, but in women it was the ability to correctly recognize friendship that got better. Professor Ryan thus concluded: "Our experiment proves that the hormone oxytocin can raise people's abilities to better distinguish different social interactions. And the behavior differences between men and women are caused by biological factor that are mainly hormonal."
Answer: Oxytocin.

Article: Whether we should allow marine parks to stay open has been widely debated in our community recently. A variety of different arguments have been put forward about it. Smith, a sociologist, argued that dolphin parks provide the only opportunity for much of the public to see marine mammals. As this argument goes, most Australians live in cities and never get to see these animals. Marine parks allow the average Australian to appreciate our marine wildlife. However, in fact, there are many places where they can be seen in the wild. Moreover, these places do not charge an overpriced entry fee -- they are free. Dr. Alison Lane, the director of the Cairns Marine Science Institute, insists that we need marine parks for scientific research. She argues that much of our knowledge of marine mammals comes from studies which were undertaken at marine parks. The knowledge which is obtained at marine parks can be useful for planning for the preservation of marine mammal species. However, Jones, a zoologist, explains that park research is only useful for understanding captive animals and is not useful for learning about animals in the wild. Their diets are different, they have significantly lower life lengths and they are more likely to have a disease. In addition, marine mammals in dolphin parks are trained and this means that their patterns of social behaviour are changed. The Marine Park Owners Association holds that marine parks attract a lot of foreign tourists. This position goes on to state that these tourists spend a lot of money, increasing our foreign exchange earnings and assisting our national balance of payments. However, foreign tourists would still come to Australia if the parks were closed down. Indeed, surveys of overseas tourists show that they come here for a variety of other reasons and not to visit places like Seaworld. Tourists come here to see our native wildlife in its natural environment and not to see it in cages and concrete pools. They can see animals in those conditions in their own countries. In a word, perhaps an agreement cannot be reached now. However, a question does deserve our consideration: If we continue with our past crimes against these creatures, how will our future generations view us?
Answer: Jones.
