34. 1) in 2) by 3) at 4) on Im so 30____on adventure. I always remember the stories about my grandfathers expedition. My granddaddy, Jim Edward Freeman from Australia is the person to walk the length of the Amazon River. He started by a small stream in the Andes mountains of Peru and arrived 31____ the rivers mouth in Brazil, two years and four months later, having walked 6,000 kilometers. The Amazon rainforest is home to poisonous snakes, crocodiles and jaguars, so he was in constant danger. Luckily, my grandfather survived with nothing worse than a few thousand mosquito and ant bites. On his trip, Ed had to find food to eat every day. A lot of the time, fish and meat were hard to find and he had to substitute it 32_____fruit and nuts. Thats why he often felt weak and exhausted. Eds walk would have been impossible without technology. He used a radio to ask the people of the rainforest for food and permission to cross their land. Many of them came to meet him and provided him 33 ____ food and clothes. As he walked Ed wrote a blog, recording his day-to-day experiences. He used the media interest in his trip to protest about the destruction of the rainforest and raise money for environmental and childrens charities in Brazil and Peru. I always wanted tofollow 34____my grandfather'sfootsteps. So after I had 35____ from university, I participated in various volunteer programs. Today Im a leading expert on Geographical Exploration Area. Without any doubt, my descendants will never be disappointed 36____ me.
