01 【长难句】

　　In each case the pattern is the same: young people adopt a new form of entertainment, older people are spooked by its unfamiliarity and condemn it, but eventually the young grow up and the new medium becomes accepted—at which point another example appears and the cycle begins again.

　　02【句型分析】

　　冒号将句子分为两部分，冒号后面对前面进行解释，其中 以but为切入点，得到并列结构“…，…，but…and…”即young people…, older people…, but eventually the young…and…其中第二个并列结构older people are spooked by its unfamiliarity and condemn it中又由连词and并列两个谓语。破折号后面使用定语从句，其中which指代上文的一整句the new medium becomes accepted，其中从句中又由and并列两个分句another example appears和 the cycle begins again。

　　03【词汇】

　　spook 惊吓

　　condemn 指责

　　medium 媒体

　　at..point 此刻

　　04【参考译文】

　　每一个实例都有着相同的模式：年轻人接受了一种新的娱乐形式，年长的人因陌生而受惊，于是对其批评指责。最终，年轻人长大成人，于是新媒体被社会承认——此时，另一种娱乐形式出现，循环模式再次开始。
