点评 解题策略
1）从意思上判断 在做题时最重要的是要读懂空白前后的句子，正确理解了这些句子后，根据意思的连贯性、逻辑性或者线索词从选项中选取正确答案．在读懂意思的基础上，再利用线索特征词等进一步确认答案．
2）从词汇上锁定线索 做保持对一些线索词的敏感是非常重要的，要好好关注空白前后的名词和动词，然后在选项中查找它们的近义词、反义词、同义词、同类词等．其次是一些专有名词，比如说数词、代词、时间、年代、地点/名称等．尤其是在读不懂句子的情况下，利用这样的线索词寻找答案是很有效的方法．
3）从关联词作为切入点 通常，英语的句段之间经常会运用关联词表示过渡和衔接，让文章的思路与更清楚、逻辑更连贯，因此文章中和选项中表示各种逻辑关系的路标性信号词在选择答案时都是很重要的线索．在做题时可将这三个层面的线索很好地结合起来．
