A. disappointed
B. excited
C. joyful
D. indifferent
题目解答
答案
A. disappointed
解析
本题考查形容词辨析，需要根据语境选择最合适的表情描述词。关键在于理解两种持笔方式对表情的影响：用牙齿咬笔会形成“人工微笑”，而用嘴唇叼笔则会产生相反的表情。需结合表情特征（如嘴角方向）排除干扰项。
语境分析
- 前半句：用牙齿咬笔（teeth）→ 人工微笑（smile），嘴角上扬。
- 后半句：用嘴唇叼笔（lips）→ 表情应与微笑相反，即嘴角下垂，体现负面情绪。
选项辨析
- A. disappointed：失望时嘴角下垂，符合“与微笑相反”的逻辑。
- B. excited、C. joyful：均表示积极情绪，与“微笑”相似，排除。
- D. indifferent：中性情绪，未体现嘴角下垂，排除。
