[典例剖析] 选词填空。
1.
(How a/What a) grand festival! The streets are filled with people celebrating.
2. Steve took the money he found to the police station. What
(a/an) honest boy!
3. How
(good/well) this activity is organized! I must thank all my teachers and classmates.
答案：1. What a
2. an
3. well
解析：
1. 本题考查感叹句的用法：What引导的感叹句结构为"What a/an + 形容词 + 可数名词单数!"，How引导的感叹句结构为"How + 形容词/副词 + (主语+谓语)!"，不存在"How a"的正确用法，此处后面是"grand festival"，符合What a的感叹句结构，因此选What a。
2. 本题考查不定冠词的用法：单词honest发音以元音音素开头，因此要使用不定冠词an。
3. 本题考查形容词和副词的辨析：此处需要修饰动词短语"is organized"，修饰动词要用副词，good是形容词，well是副词，因此选well。
