原文： Although reality show are not scripted or cast in a traditional sense, they are well planned, and they are carefully orchestrated. Certain aspects of each episode are scripted in the traditional way: A host reads words written by a producer or writer. Other aspects are shaped with the same care that once went into planning a complicated talk-show segment, or with the repeated run-throughs of game elements that game shows typically require prior to air--necessary to ensure smooth taping, especially during crucial competitive sequences.

说实话，Other aspects...sequences 这一整句话都没看懂，哪位能帮在下解释下这个长句的意思么。不胜感激！
