Most of the boys want to be explorers, and the two brothers are among them. For Ollbie and Harry, life is an adventure. For the past several years, the brothers have been working to _______ a list of 500 challenges and experiences.

"The idea came about actually from the boys," their father, MacNeill Ferguson, said. "The boys were just asked one day if they could come up with some cool things for us to do as a family. They _______ some impossible ideas firstly, like going on a trip to Mars, International Sausage Day and all kinds of _______ kids' requests. They built the list to a hundred, then kept finding new things they wanted to go and try... until it got up to 500." They're all listed on the brothers' Facebook page.

So far, they have built an igloo (圆顶小屋),explored the wilderness, and sent their Lego men to the depths of the ocean and into outer space. Perhaps their biggest adventure is playing out right now on the high seas. Last year, Ollbie and Harry's "Adventure", one of their toy ships _______ from the Scottish coast. It sailed across the North Sea to Scandinavia. It then began a ride on a Norwegian boat and was launched again. _______, they had equipped the toy ship with a tracking device (跟踪器). It allowed the brothers to know every step of the sailing well. But the battery on the tracking device is becoming weak, so Harry and Ollbie hope a passing ship notice their boat and is able to recharge (充电) its battery, allowing the trip to continue.

"I want it to go to Australia because that would be halfway around the world, and there's lots of beaches there," Ollbie said.

"Harry, where would you like the boat to go?" Ferguson asked. Without any _______, Harry replied, "that would be China because we all love China." He thought that even there were so many difficulties the boat would reach China.
