亲，首先，我给你的2首歌的链接都是永久链接哦，请放心，我的qq空间能听，其它网友也能听，下面解决你的问题，请尝试：1、去音乐盒检查一下，是否完整复制了这个链接（链接以“a.mp3”结尾）？或者不小心把链接前后的空格或冒号之类的也复制进去了？另外，在音乐盒中输入歌名时，把《Safe & Sound》改成《Safe and Sound》，因为“&”是QQ空间被限制的特殊符号之一；2、如果复制得没问题，那么，刷新当前页面，点击播放；3、退出qq空间、重新登录，点击播放；4、网络或网速或电脑问题，请看其它歌曲是否都能听；5、请好友进你空间看看能不能听到？（不要在你自己电脑上用你其他小号进去听）6、如果其他人进你空间能听而你自己听不到，请换个浏览器试试；
你给的链接的确是能动的
但怎么就是我怎么也听不到啊
我用搜狗和360都没听到
亲，你现在的情况是其他人进你空间能听而你自己听不到是吗？请试试IE浏览器，以前遇到过一位网友，他本来是用360极速浏览器，听不到声音，后来换IE浏览器后就能听了。如果还是不行，可能是你QQ空间暂时性抽风了？这方面俺还真不算专业~~

Only in the Twentieth Century has his vision come to pass. The earliest men to leave the surface of the earth were the Montgolfier brothers with their early hot air balloons.In the last half of the 19th Century, more sophisticated balloons were used initially for novelty and then for spotting military targets particularly during the 1870 Franco-Prussian War.However, it was only with the gliders of Otto Lilienthal that man rose into the air, albeit briefly, supported by wings. The gliding exploits of the German Professor sparked the imagination of the two young American brothers Orville and Wilbur Wright, who at the turn of the Century were fascinated by box kites which could be powered by the newly invented internal combustion engine.In 1903 at a place called Kittyhawk, the brothers left the surface of the earth for the first time in a powered machine. Since then, man has striven to produce machines which fly higher and faster and carry passengers so that the Twentieth Century has seen like no other, earthbound man accelerate to one and a half thousand miles an hour with luxury air travel at seven miles above the Earth.In military terms, man has flown even higher and faster, some say at speeds exceeding 5,000 miles per hour on the edge of space. But the greatest achievement of all came when with political determination and the invention of the rocketship, science fiction became fact and man first walked on the surface of Earth's moon.Since then, he has sent rocket launched satellites to the far corners of our solar system in order to send back data and photographs of the surface of other planets in our galaxy.By the constant linkage of aviation to warfare, man has accelerated his conquest of the skies by striving to produce more and more efficient aerial killing machines.It was the rapid development of military aviation in World War I which produced the Vickers Vimy which carried Alcock and Brown across the Atlantic Ocean for the first time in 1919, to be followed in 1927 by the first lone aviator to cross the Atlantic - Charles Lindbergh.Since Lindbergh's daring journey which inspired a generation, man has developed air transport which today is typified in the shape of the giant Boeing 747 Jumbo Jet. This aircraft has undoubtedly revolutionised air transport for the masses and has brought travel to the furthest points on the earth's globe at an affordable level for most people, in under twenty-four hours travelling time.The series has been compiled with access to some of the rarest archive film ever taken. Unprecedented co-operation has been extended to the Producers by the world's leading aircraft manufacturers and leading archive libraries.These stories have not always ended in success and included in the footage are rare shots of prototype accidents and failures which contributed to the inevitable achievement and success of man in the air. The Century of Flight is the largest series ever produced on man's victory in the skies.Over 250,000 hours of material have been examined by international experts to assemble the most definitive story of manned flight ever produced this century.THE 26 PROGRAMMES(26 x 52 minute episodes)1 Man Learns To Fly (1900 - 1914)2 High Above the Trenches (Military Aviation 1914-18)3 Wings Over the Sea (Naval Aviation 1914-18)4 Strike from the Air (Birth of Strategic Bombing 1914-18)5 The Trailblazers (Epic Flights 1919-39)6 The Romance of the Air (Civil Aviation 1919-39)7 The Shadow of the Bomber (Military Aviation 1919-39)8 Struggle for the Skies (Fighters of World War II)9 Airpower and Armies 1939-4510 Airpower and Navies 1939-4511 The Bomber as War Winner?

The programme framework includes a comparison to all forms of modern flight, the early dream of flight, hot-air balloons, kites and gliders, early powered flight, early pioneers, early attempts at speed and distance records including Bleriot's English Channel crossing, the Zeppelins and the build-up to World War I.2) High Above the TrenchesHow the aeroplane went to war, with the development of the combat aircraft from the unarmed reconnaissance types to specialised fighters. The programme includes simulated air combat by replica fighters in colour, reviews the part played by aircraft in the early part of World War I including the coming of the Fighting Scout. Also featured is the heyday of air fighting on the western front, 1917-18, including fighter ground attack, the great aces and the way in which the legacy of these years inspired pilots in the modern day.3) Wings Over the SeaThis programme covers the development of naval aviation during the Great War. We travel back from the aircraft carriers today to see how early aircraft were used initially for observation for the fleet. Early float planes led to the development of long range flying boats and the coming of the aircraft carrier heralded a new age of aircraft versus ship. In combating other ships, including submarines, colour footage shows how the aircraft became the ship's greatest enemy.4) Strike from the AirThe aircraft soon bought civilians into the firing line as never before and brought about a new form of total war. The programme shows the origins of aerial bombing initially from Zeppelins. In turn, how the Zeppelins were defeated and how heavy bombers were developed by the major nations. Strategic bombing is examined in terms of its early role to hit targets behind the trenches, eventually extending to civilian targets as well as industrial targets.5) The TrailblazersA review of the great long distance flights and those aviators who achieved them including colour re-enactments by restored and replica aircraft. The great transatlantic flights are featured together with those to the Orient and Africa. The conquering of the Pacific is covered including Amelia Earhart and the mystery of her disappearance, how both Poles were overflown and the way in which these early exploration craft paved the way for modern airliners.6) The Romance of the AirA review of heroic days of civil aviation. How civil airlines began in Europe and USA during the 1920s. Airship versus Aircraft - rivalry for transatlantic routes, culminating in the R101 and Hindenburg airship disasters.

Rearmament - creation of the Luftwaffe, expansion of the Russian Air Force, reaction of western democracies. Dress Rehearsals - the use of airpower in Abyssinia, Spain and China during the late 1930s.

The future - where space exploration is going.25) Madcaps and OddballsJapanese manpowered flight competition. Manpowered flight - the story from Icarus and Daedalus to Kanellopolous's 1988 distance record. Footage includes many bizarre attempts down through the decades, with a fair degree of colour and humour. Diagrams explain the problems of manpowered flight. It will never fly - Zany home-made flying machines 1900-39. Humour is the keynote. Wartime Oddballs - German piggyback aircraft and other projects, the flying jeep, and many more. White Elephants - expensive projects that hardly got off the ground. These will include Howard Hughes' Spruce Goose, the Northrop Flying Wing, and the British TSR project.
