一个合格的侦探应具备基本的逻辑推理能力。所以，基于我们对动词过去时变化的学习，推断出这些单词的比较级。我相信你们，你们是我最得意的学生。
单词 原级 比较级
outgoing 外向的
boring 无聊的
hard-working 勤奋的
more outgoing
more boring
more hard-working
这几个是特殊情况，需要我摩尔侦探的帮助：
它们属于多音节形容词，英语中多音节形容词（一般三个或三个以上音节 ）的比较级通常借助 more 来构成 ，不能直接加 -er 。
单词 原级 比较级
good 好的
动词过去式中存在不规则变化，如：
give – gave; go - went
better
My English is good, but yours is better.
比较级中也有这样的情况
Summary
1. 一般直接加-er：tall → taller, strong → stronger
2. 以e结尾加-r：nice → nicer, fine → finer
3. 辅音+y结尾变y为i加-er：happy → happier
4. 多音节词：前加more：beautiful → more beautiful
5. 不规则变化：good-better
