试述广播节目系统构建的原则
(1)坚持以新闻广播节目为中心的原则
在广播电视节目大系统中，新闻节目是广播电视节目系统的基础;新闻节目的质量决定着这个节目系统的健康运行。
(2)坚持节目本位的原则
节目是构成节目系统的重要元素，因此在构建节目系统时要坚持以节目为本，即一切工作环节、一切体裁、一切样式必须以节目为出发点和最终落脚点，以节目统率一切，一切为节目服务。
(3)有利于开发拓展黄金时段的原则
广播历来按照人们的一般作息习惯，把全部播音时间分为黄金时间和非黄金时间。现在还出现了介于二者之间的次黄金时间。
(4)坚持节目系统开放性原则
节目系统要做成开放的系统，而不是封闭的系统。开放的系统需要不断地解构，即不断地打破固有封闭系统，然后再重新整合。

Relaxation therapy ( = treatment). If you read the sentence out loud, your blood pressure will go up. If you talk to another person, it will go still higher. If the talk is with your boss, your pressure will go even higher. If you speak to someone of the opposite sex, your pressure may show less change if you ’ re married than if you ’ re single. Dozens of times each day, your blood pressure changes with what you ’ re feeling and doing. These “ ups and downs” take place in everyone, but they are more severe in people with high blood pressure. That discovery is the basis for the newest therapy: controlling blood pressure by learning skills to control everyday stress. Many patients control their blood pressure with the relaxation response. This takes four simple things: a quiet environment, a comfortable position (sitting or lying down), the repeating of a word, prayer or phrase each time you breathe and having none of other thoughts. Something remarkable happens when you do this, according to research in Boston. Relaxation of the mind and body has the effect that some blood-p ressure pills would have. What ’ s more, the blood pressure stays lower, just as it would with a pill, after you have stopped the relaxation and have returned to the stress of daily life.
