The Great Barrier Reef stretches (伸展) out for 2,000 kilometers along the coast from the very northern tip of Queensland, Bamaga, to Bundaberg, better known as the Capricornia section of the Reef (it actually goes on until Papua New Guinea). It's a sort of Australian Wall made out of different ecosystems that is also visible from space. Cairns is one of the major points from which to set off for a trip to the reef. Although you can reach many spots from whatever place on the eastern coast of Queensland, many people choose Townsville.
From Townsville, you can easily set off for the Great Barrier Reef Marine park, which consists of hundreds of impressive deserted islands with quiet beaches where you can stay for a few days and explore the reef area with snorkeling or diving equipment. Although housing is expensive, one of the cheapest choices is probably camping. Make sure you have brought along everything you needed. The closest island to the coast is Long Island and visited by many people who want to explore the barrier reef for only a day or a few hours. Maybe it's a good idea to set off for one of the many other islands or islands groups such as the Whitsunday Islands or the Mollie Islands, Daydream Island, Hook Island, Lindeman Island or Hamilton Island, and these are only a few of the many. At the Capricorn section it is more expensive to get from the coast to one of the island. However, islands such as North West, Lady Musgrave and Tyron (all of them being national parks) offer the perfect spot for relaxation.
A little bit more to the south, you will find Fraser Island. Although the reef does not extend to this island, it is a beautiful mixture of sand, sea, forests and lakes.
28．We can infer from the text the real length of the Great Barrier Reef is ________.
A．2,000 kilometers
B．more than 2,000 kilometers
C．less than 2,000 kilometers
D．2,000 kilometers or so
答案：B 推理判断题。根据文章第一段第一句可知，大堡礁从Queensland的最北端到Bundaberg是2000公里，但实际上它一直延续到Papua New Guinea，所以可以推断其长度大于2000公里。
29．It seems that many people like to start their trip from ________.
A．Bamaga B．Bundaberg

答案：C 细节理解题。由文章第一段最后一句可知，虽然人们可以从Queensland东海岸的任何的一个地方到达很多景点，但很多人都选择Townsville。
30．If you want to explore the barrier reef in a short time, you can visit ________.
A．Hamilton Island B．Hook Island
C．Daydream Island D．Long Island
答案：D 推理判断题。根据文章第二段第四句可知，离海岸最近的岛屿是Long Island，很多要在大堡礁探险的人们只需要一天或几个小时。
31．________ is not a national park in Australia.
A．North West B．South West
C．Tyron D．Lady Musgrave
答案：B 细节理解题。根据文章第二段最后一句可知，是国家公园的有North West, Lady Musgrave和Tyron。
