通用性的解题方法
    完形填空的基本解题原则是从已知信息中寻找定位出所有与未知填空相关联的信息线索，通过综合分析这些线索推测未知填空的答案。在这里总结一些具有普遍性的寻找定位相关已知线索的方法和规律，这些方法大多适用于动词、名词、形容词和副词。
    1)无关词排除法(与主题相关原则)
    完形文章一般都有非常明确的中心主线，且整个文章很紧凑，就是紧紧围绕着中心主线展开。因此，理论上正确的选项一定是紧扣文章的主题和中心主线的。故而，一些看上去明显和文章主题和中心主线毫无关系的选项基本上可以排除在正确答案之外。
     The government is to ban payments to witnesses by newspapers seeking to buy up people involved in prominent cases 31 the trial of Rosemary West.
     In a significant 32 of legal controls over the press, Lord Irvine, the Lord Chancellor, will introduce a    33 bill that will propose making payments to witnesses 34 and will strictly control the amount of      35 that can be given to a case 36 a trial begins.
     35. A) publicity     B) penalty        C) popularity      D) peculiarity

2)同现结构法(与文章主题导向或倾向一致原则)
        同现是一种词汇的衔接手段。完形文章由于常常有明确的中心主线，所以作者往往会使用一些重点词汇围绕着中心主线贯穿全文。同现实际上就是一组具有相同倾向性的词语，这些词语所表现的倾向性往往与中心主线中的导向一致，或者说这些同现词语的任务就是对文章的导向进行支持。因此，文章的整体导向可以成为解出这些同现词语的关键信息。
Sleep is divided into periods of so-called REM sleep, characterized by rapid eye movements and dreaming, and longer periods of non-REM sleep. 41 (Neither) kind of sleep is at all well-understood but REM sleep is 42 to serve some restorative function of the brain. The purpose of non-REM sleep is even more     43 .
     43. A) subtle        B) obvious         C) mysterious      D) doubtful

3)复现结构法(与本题一致原则)
    复现是完形文章中词汇的一种衔接手段，即表达相同意思的词汇在文章的不同地方出现。复现可以是相同的词重复出现，也可以是用不同的词表达相同的意思。复现的解题意义在于：如果判断出一个未知填空与—卜下文的一些已知词汇有复现关系，只要从选项中选出与那些词汇意义相同的即为正确答案。
     Sleep is divided into periods of so-called REM sleep, characterized by rapid eye movements
and dreaming, and longer periods of non-REM sleep.     41 kind of sleep is at all well-understood, but REM sleep is    42 to serve some restorative function of the brain. The purpose of non-REM sleep is even more     43 .The new experiments, such as these     44 for the first time at a recent meeting of the Society for Sleep Research in Minneapolis, suggest fascinating explanations     45 of non-REM sleep.
     For example it has long been known that total sleep     46 is 100 percent fatal to rats, yet, 47     examination of the dead bodies, the animals look completely normal. A researcher has now    48     the mystery of why the animals die. The rats     49 _bacterial infections of the blood,     50 their immune systems—the self-protecting mechanism against disease—had crashed.
