Срочно!!!!! надо сделать план текста небольшой!!!A. Young people are active participants in theirown history. Past generations of radical studentshave played a role in protests and revolutions againstthe existing social order. The youth movement is ideological or political in nature.At the same time, ordinary young people usuallybelong to the youth movement through membershipin an adult-led voluntary youth organization, such asScouts or guides. There are also"youth cultures" focused on fashion, which are determined by the types of clothing, musicand language. The term "youth movement" is sobroad, which can apply to both punk rockers and young conservatives.B. The world's first voluntary youth organizationwas the church-based Boys' Brigade, foundedin Glasgow, Scotland, in 1883 by William AlexanderSmith (1854-1914) and devoted himself to religiouseducation and the development of habits of obedience,reverence, discipline, self-respect and all thatleads to true Christian manhood.In the 1900s, there was a movement of middle-class students in Germanywho engaged in outdoor vagrancy, Richard Schirmann, a German schoolteacher, opened the first youth hostel in 1909. Youth hostels providing cheap accommodation for young people are now found in most regions of the world. In England, Major General Robert Baden-Powell (1857 - 1941) in 1908 founded the movement of loggers in uniform - Boy Scouts, like boys". The Brigade, the scout movement has spread all over the world, is a sister organization to the Scouts. The Association of Girl Guides, founded in 1910, also has a large number of members around the world, these organizations teach boys and girls various useful skills, such as campfire, cooking, fishing, as well as to develop their character, scouts traditionally use a penknife, and their motto is "Be ready".C. Young people contributed to mass political movements of both the left and the right, inthe 1930s, youth fascist organizations functioned inMussolini's Italy and Hitler's Germany, after 1933 Membership in the Nazi Hitler Youth became mandatory, in the UK some young people joined the Blackshirts, the Austrian Red Falcons were an active socialist movement of the 1930s.There were communist youth groups in Soviet Russia:An Octobrist, pioneer and Komsomol me8mber, whose goal was the political education of youth.D. Since the Second World War the media have talked a lot about the activities of various notorious youthcults, this spreading information about them, about the Teddy Boys of the 1950s with their long jackets, corduroy collars, drainpipe trousers and shoes the crepe soles were the first of the rebellious youth cults of the working class, in the early 1960s new groups appeared, such as the Mods, dressed in Italian-style clothes, and theirleather-clad rivals, the rockers.The Hipples of the late 1960s were more muddie-class, They experimented with drugs, lived in communities, grew their hait long, and were attracted to radical politics.Skinheads, combining elements of both Mods and Rockers and associated with the racism of the far right, arrived on the scene in the late 1960s. Punk Rockers achieved notoriety through the attention of the media in the late 1970s, with their unique "Mohican" hairstyles, vivid make-up, cast-off clothes and aggressive music. Several of these youth cultures were recycled in the 1980s
