【分析】
解题思路：先明确方框内单词的词义与词性：observe（动词，观察）、expression（名词，表情）、uncomfortable（形容词，不舒服的）、immediately（副词，立刻）、reminded（动词过去式，提醒）。再结合每个空格的语法结构和上下文语境匹配单词：56空需动词原形（like to do结构），对应观察老师的动作；57空需名词（形容词修饰），对应老师的表情；58空需形容词（feel后接表语），对应Tom的感受；59空需副词（修饰动作），对应坐直的状态；60空需动词过去式（作谓语），对应同桌的动作。
【解析】
1. 56空：like to do是固定结构，需填动词原形，结合“仔细观察老师的脸和肢体语言”的语境，选observe；
2. 57空：形容词serious后需接名词，结合“严肃的表情”的语境，选expression；
3. 58空：feel为系动词，后接形容词作表语，结合“感到不舒服”的语境，选uncomfortable；
4. 59空：修饰动词短语sit up straight需用副词，结合“立刻坐直”的语境，选immediately；
5. 60空：句子缺谓语动词，结合一般过去时态，结合“同桌提醒他”的语境，选reminded。
【答案】
56. observe 57. expression 58. uncomfortable 59. immediately 60. reminded
