　[归纳点拨]
用法规则
where ...，there be ...，意为“在……地方， 有……”， where引导地点状语从句。另外 wherever“无论什么地方；无论在何处”也可引导地点状语从句。
注意事项
where在句中引导地点状语从句时，很容易和引导定语从句相混淆，区别的关键在于where前面是否有需要修饰的先行词。如：
High buildings have arisen where there was nothing a year ago.(状语从句)
High buildings have arisen in the place where there was nothing a year ago.(定语从句，先行词为the place)

[佳句背诵]

完形填空技法(6)——克服词汇多义和生义理解不透，力避“望文生义”
在英语中，不少单词有两个甚至多个意思，我们把这种现象称之为一词多义。一词多义是很普遍的语言现象。在完形填空的选项中，有时也出现一些多义词。对这类词的常见意义掌握得不够全面，会给考生在解答完形填空时带来很大的干扰，导致错选。如对第7题选项lessen的词义掌握不到位，就容易造成错选。
在复习词汇的过程中，我们要特别关注和积累熟词生义，特别是常用动词及其短语，在
解题过程中，注意认真思考，不要“望文生义”。
