【分析】
本题考查形容词比较级与最高级的用法，解题思路：1. 若句中出现than（比），表示两者比较，需用形容词的比较级，单音节词一般加-er，多音节词加more；2. 若句中出现among all...（在所有……中）、in + 范围（如in our class）、定冠词the等表示三者及以上范围的提示词，需用形容词的最高级，单音节词一般加-est，多音节词加most，且最高级前通常加the；3. 注意部分形容词的规则变化（如重读闭音节双写尾字母、变y为i加后缀等），结合语境判断用比较级还是最高级。
【解析】
1. 句中出现than，表两者比较，exciting是多音节形容词，比较级为more exciting；
2. 句中出现than，thin是重读闭音节单音节形容词，比较级双写尾字母加-er，为thinner；
3. 句中出现than，careful是多音节形容词，比较级为more careful；
4. 句中出现than，big是重读闭音节单音节形容词，比较级双写尾字母加-er，为bigger；
5. 句中出现among all the maths problems，表三者及以上范围，easy是辅音加y结尾的形容词，最高级变y为i加-est，且前加the，为the easiest；
6. 语境隐含与之前比较，hard的比较级为harder；
7. 句中出现in our class，表三者及以上范围，smart是单音节形容词，最高级加-est，前加the，为the smartest；
8. 句中出现than，short是单音节形容词，比较级加-er，为shorter；
9. 句中出现the，且语境为他的所有时刻，sad是辅音加y结尾的形容词，最高级变y为i加-est，前加the，为the saddest；
10. much修饰比较级，clever是单音节形容词，比较级加-er，为cleverer。
