【详解】考查过去分词。句意：被他的精彩演出所震撼，观众们都站了起来，热烈鼓掌。空处作句子的状语，根据“the audience were on their feet, applauding wildly”可以推测，他的表演使观众印象深刻，逻辑主语the audience“观众”与impress“使……印象深刻”构成被动关系，用过去分词impressed 。故填：Impressed。
2. The government has already taken some measures to raise public a__________ to protect the environment. （用适当的填空）
【答案】awareness##wareness
【解析】
【详解】考查名词。句意：政府已经采取了一些措施来唤起公众保护环境的意识。分析句子可知，空处位于public后，为名词。结合句意，awareness“意识”。raise ones awareness固定搭配“唤起某人的意识”。故填awareness。
