A second kind of clue does not rely on specific words to indicate the meaning. This kind of context clue is called a frameworkbased clue. Your knowledge of the meaning of surrounding words helps you discover the meaning of a word or sentence. Common sense and your knowledge of the part of speech also help define unknown words. For example，the angry driver shouted vehemently during his fight with the other driver. What does “vehemently” _56_ ？ You know what _57_ means，and you know how people feel when they argue. From this，you can figure out that “vehemently” has something to do with strong emotion or intense feelings.,典 例,56Amean. Buse Ccontain Dcomplete 57Aangry Bgrateful Chappy Danxious,解题模板,剖析：56. A 57.
