Questions 6 to 10 are based on the following passage: (10 分)In previous generations, young people were under their parents’ control; now the teenagechildren of the West’s richest generation were ready for something to get excited about. The Beatlessimply put a spark to a fuse (导火线) that was waiting to be lit.Everything changed, and what changed for the Beatles was their lives and their working habits,in the midst of the hysterical (歇斯底里的)following the band attracted.. Because of the demand ofthe fans to see them perform, they played bigger and bigger venues (meeting places), especially inAmerica.But John, Paul, George and Ringo became increasingly unhappy that, because of the screamingof their fans, neither the band nor the audience could hear the music. Creatively frustrated and tiredof the pressures of life under siege (围攻) from their fans, they retired from playing concerts in 1966and decided to concentrate on recording.It was from this point that the brilliance of the Beades really began to reveal itself: they wouldrecord over their career some 200 songs.
