trustworthy person he is!
【答案】 What a
【详解】句意：他是一个值得信赖的人。改为感叹句，此处中心词是名词person，应用What+a/an+形容词+名词+主谓结构，又因为trustworthy是以辅音音素开头的单词，所以用不定冠词a。故填What；a。
36．最后，我成功了。我多么兴奋啊！
At last, I succeeded. I was!
【答案】 How excited
【详解】对照中英文，此处缺少“多么兴奋”。分析句子结构可知，该句为感叹句，结构为：how+形容词+主谓。excited“兴奋的”，用来修饰人，形容词作表语。故填How；excited。
37．老师们都是多么努力工作啊！
the teachers are working!
【答案】 How hard
【详解】本题考查感叹句。感叹句有两种常见结构：“What+(a/an)+adj.+n.+主语+谓语!”和“How+adj./adv.+主语+谓语!”。这里强调“努力工作”，“努力地”是副词“hard”，所以用“How”引导感叹句。故填How；hard。
38．多么美妙的歌声啊！她将来一定会成为著名的歌手。
the girl sings! She will surely become a famous singer in the future.
【答案】How wonderfully
【详解】由汉语和英语翻译可知，空格处缺少“美妙的”的英文。“wonderful”意为“美妙的”，此处是感叹句，修饰动词，需用副词wonderfully，符合“How＋副词＋主语＋谓语！”结构。故填How wonderfully。
39．孩子们在美术课上画得多么认真啊！
the children are drawing in the art class!
【答案】How carefully
【详解】对比所给中英文可知，此句为感叹句，carefully“认真地”，修饰谓语动词，此处应用how引导感叹句，结构为“How + 副词 + 主谓!”。故填How carefully。
40．他们有一种多么特别的学习方法啊！
learning method they have!
【答案】 What a special
【详解】中英对照可知，该句为感叹句，本句中心词method是可数名词单数形式，应用what引导的感叹句，结构为“what+（a/an）+形容词+可数名词单数+主语+谓语”，special“特别的”，形容词，以辅音音素开头，用不定冠词a。故填What；a；special。Unit 2 Great inventions and discoveries
