解析：
【分析】
本题主要考查形容词的原级、比较级用法，解题思路如下：1. 先识别句中的关键标志词：than（比较级标志）、as...as（原级标志）、“the + 比较级，the + 比较级”（固定结构）；2. 根据语境判断所需的形容词级别（原级/比较级）；3. 结合形容词的变化规则（单音节词加er，多音节词加more等）及名词的可数性（如fast food为不可数名词），选出正确形式。
【解析】
(1) ① 句中出现比较级标志词than，需用形容词比较级；结合语境“学会放松比成绩更重要”，important是多音节词，比较级为more important，故选C。
② 考查固定结构“the + 比较级，the + 比较级”，意为“越……就越……”；结合语境“越努力，越幸运”，hard-working的比较级是more hard-working，lucky的比较级是luckier，故选A。
③ 句中出现比较级标志词than，需用形容词比较级；结合常识“现在的火车比以前更快”，fast的比较级是faster，故选B。
④ 语境要求“少吃快餐，多吃新鲜蔬菜”，fast food是不可数名词，修饰不可数名词表示“更少”用less，故选A。
⑤ 句中出现比较级标志词than，需用形容词比较级；结合常识“大象比马更大”，big的比较级是bigger，故选B。
(2) ① 句中出现比较级标志词than，clean的比较级是cleaner，故填cleaner。
② 句中出现比较级标志词than，hard-working是多音节词，比较级为more hard-working，故填more hard-working。
③ 句中出现比较级标志词than，funny的比较级是funnier，故填funnier。
④ 语境表示“（比这个背包）更便宜的”，需用cheap的比较级cheaper，故填cheaper。
⑤ as...as结构中需用形容词原级，故填beautiful。
【答案】
(1)①C ②A ③B ④A ⑤B
(2)①cleaner ②more hard-working ③funnier ④cheaper ⑤beautiful
