原级(形容词或副词的原形)比较级对照
大多数单音节形容词和副词 (tall, fast, hard, yung, ld, shrt, lng, high, lw, great, small, clean, new, cld, warm, cl, ht, bright, dark, light, sweet, lud, quiet, slw, quick, strng, weak)加 -er。 部分以-y, -er, -w, -le结尾的双音节形容词和副词 (通常也是较短的词)。例词：tall -> taller (高的 -> 更高的)fast -> faster (快的 -> 更快地)hard -> harder (努力的；努力地 -> 更努力的；更努力地)
大多数三个或三个以上音节的形容词和副词 (beautiful, imprtant, difficult, interesting, carefully, slwly, easily, cmfrtably, expensive, delicius, dangerus, ppular)加 mre。大部分双音节形容词和副词 (尤其是那些不以-y, -er, -w, -le结尾的)。在形容词或副词前加 mre。beautiful > mre beautiful (美丽的 > 更美丽的)imprtant > mre imprtant (重要的 > 更重要的)carefully > mre carefully (小心地 > 更小心地)slwly > mre slwly (慢地 > 更慢地) (虽然以ly结尾，但slw本身是形容词/副词，双音节常用mre)
不规则变化：gd/well -> better (好的/好地 -> 更好的/更好地)bad/badly -> wrse (坏的/坏地 -> 更坏的/更坏地)many/much -> mre (许多 -> 更多的) (用于可数/不可数名词)little -> less (少的 -> 更少的) (用于不可数名词或表示程度)far -> farther/further (远的 -> 更远的/进一步的) (farther 通常指物理距离，further 可指物理距离或抽象程度)ld -> lder/elder (年长的 -> 更年长的/年长的) (lder 通用，指年龄或新旧；elder 通常只作定语指家庭成员中较年长的，如elder brther/sister)
比较级通常用于比较两个人或事物（A 和 B）。最核心的结构是：A + 动词 + 比较级 + than + B.A 和 B 必须是可比较的同类事物; than 是连接词，引出比较的对象 (B)。形容词比较级作表语（在系动词如 be, lk, seem, becme, feel 等后面）或定语（放在名词前）。副词比较级修饰动词、形容词、其他副词或整个句子，通常放在被修饰词之前（但 enugh 除外）。eg: 1.My brther is taller than me. 2.He fund a mre cmfrtable chair. 3. Please speak mre slwly.
I’m a little quieter than Ella.I’m feeling much better tday.
(1) 表示两者在某一方面相同时，用“as + 形容词或副词原形 + as”的句型。eg：This apple is as sweet as that ne. 这个苹果和那个一样甜。 Tm runs as fast as Jhn. 汤姆跑得和约翰一样快。(2) 表示一方在某一方面不及另一方时，用“nt as / s + 形容词或副词原形 + as”的句型。eg：This mvie is nt s interesting as the bk. 这部电影不如书有趣。 He desn’t wrk as hard as his classmates. 他学习不如同学努力。

Language pints
The ppulatin f Vancuver was smaller than that f Guangzhu in 2024. 2024年温哥华的人口少于广州。

ppulatin n.人口
eg: The ppulatin f this city is increasing rapidly.这座城市的人口正在迅速增长。
（2）指人口“多”时，用 ；人口“少”时，用 。
eg: Shanghai has a large ppulatin. It is ne f the mst ppulus cities in China.上海人口众多，它是中国人口最多的城市之一。
（3）提问“有多少人口”时，用 。
eg:What is the ppulatin f Canada? 加拿大的人口是多少？
【ppulatin的用法总结】ppulatin指“人口”对它提问用what，不用hw many/hw much；人口多用large，人口少用small；人口增加用grw，人口减少就用fall。
