Grammar Rule in 30 Seconds
Use '-er' for short words and 'more' for long words to compare two things using 'than'.
- Add '-er' to one-syllable adjectives like 'fast' to get 'faster'.
- Change '-y' to '-ier' for two-syllable words like 'happy' to get 'happier'.
- Use 'more' before adjectives with two or more syllables like 'more expensive'.
Overview
bigger，cheaper，或者 more interesting。这个语法点对 A2 学习者来说至关重要。它让你超越简单的描述，比如 It is big，进入更复杂的思维，比如 It is bigger than I thought.。当你网购、谈论朋友或抱怨天气时，都会用到它。这是你英语工具箱里最实用的工具之一。没有它，你就只能用那些无法展示全貌的基础句子。而且，它会让你的八卦更有效率。谁
taller？谁 smarter？你需要这个才能知道。How This Grammar Works
-er 会让它变得很拗口。想象一下说 interestering-er。你的舌头会打结的。这就是为什么我们用 more。另外，别忘了 than 这个词。它是你正在比较的两件事物之间的桥梁。没有 than，比较就不完整。就像说 I am taller... 然后直接走开。比什么高？长颈鹿？乐高积木？我们需要知道！
Formation Pattern
-er。Fast 变成 faster。Small 变成 smaller。
Big 变成 bigger。Hot 变成 hotter。（把它想象成这个词变得格外强壮，以支撑新的词尾）。
-y 结尾的双音节形容词，把 -y 改成 -i 并加 -er。Happy 变成 happier。Easy 变成 easier。
more。Expensive 变成 more expensive。Beautiful 变成 more beautiful。
than 来引入第二项。A is [comparative] than B。
good -> better，bad -> worse，far -> farther/further。这些是英语语言中的叛逆者。它们不遵守规则，但我们依然爱它们。
When To Use It
The city is noisier than it was ten years ago. 在社交媒体上用它们来比较你和别人的生活（要小心！）。当你在餐厅决定要 cheaper 的汉堡还是 more expensive 的牛排时使用它们。它们非常适合旅行 Vlog：This view is more incredible than the last one! 在面试中，用它们来展示成长：I am more organized now than in my last role. 基本上，只要你看到两样东西，其中一样比另一样拥有“更多”某种特质，就用这条规则。它就像是你观点的超能力。
Common Mistakes
more bigger 或 more faster。这就像同时戴两顶帽子——看起来很傻而且没必要。选一个！要么用 -er 尾巴，要么用 more 助手。另一个常见的口误是用 that 代替 than。记住：than 是用于比较；that 是用于指代。别忘了不规则变化。人们常说 gooder 或 badder。虽然很可爱，但那是错的。要用 better 和 worse。最后，注意 CVC 双写规则。把 bigger 写成 biger 是一个小错误，但会让你看起来 less professional。（看到我做了什么吗？Less 只是 more 的反义词）。Contrast With Similar Patterns
the biggest 或 the most expensive）是当你有三个或更多事物，并且你要选出绝对赢家时用的。比较级严格用于 1 对 1 的对决。另外，把它和 as... as 句型对比一下。虽然 taller than 表示差异，但 as tall as 表示平等。当一个人在身高比赛中获胜时用 taller than。当打成平手时用 as tall as。把比较级想象成电子游戏里的 VS 模式。永远是玩家 1 对战玩家 2。如果整个大厅都参与进来了，你就进入了最高级的领域。Quick FAQ
我可以用 more 搭配短形容词吗？
通常不行，但在非常随意的口语中，有时为了强调会这么用。不过，为了考试和听起来自然，还是坚持用 -er 吧。
单词 fun 呢？
Fun 有点怪。虽然它是一个音节，但大多数人说 more fun。Funner 确实存在，但听起来很幼稚。
是 farther 还是 further？
Farther 通常用于物理距离（英里/公里）。Further 用于抽象距离（更多信息）。但老实说，大多数母语者会混着用。
我总是需要 than 吗？
只有当你提到第二件事物时才需要。如果大家都知道你在说什么，你可以提前结束：
I want a cheaper one.

Smart Tips
If it ends in -y, -er, -le, or -ow, it usually takes '-er'. If not, 'more' is a safer bet.
Use 'much' or 'way' before the comparative to add emphasis.
Always use 'than' followed by a subject pronoun and a verb.
Check if it's a 'CVC' word. If it is, double that last letter before adding -er.
发音
The Schwa Suffix
The '-er' ending is almost always pronounced as a weak schwa /ə/ in British English or a rhotic /ər/ in American English. Do not stress it.
Linking 'Than'
The word 'than' is usually reduced to /ðən/. It links quickly to the following word.
Comparison Stress
This one is BIGGER than that one.
We often stress the comparative adjective to emphasize the difference.
记住它
记忆技巧
Short is Sweet: Add -er. Long is Strong: Use More.
视觉联想
Imagine a short person standing on a box labeled '-er' to reach a high shelf, while a tall person (long word) just needs a friend named 'More' to help them.
Rhyme
If the word is short and small, add -er to stand tall. If the word is long and wide, put 'more' right by its side.
Story
Once there was a small cat named 'Fast' who wanted to be 'Faster', so he ate an '-er' cookie. His friend, a big elephant named 'Intelligent', couldn't fit the cookie, so he just carried a sign that said 'More'.
Word Web
挑战
Look around your room. Find two objects and say three comparative sentences about them (e.g., 'The lamp is taller than the book').
文化笔记
Using comparatives can sometimes sound rude if you are comparing people directly. It is often softer to use 'not as... as'.
Americans frequently use 'than me' or 'than him' (object pronouns).
In very formal British English, you might still hear 'than I' or 'than he', though it is becoming rare.
The '-er' suffix comes from Old English '-ra', which is shared with other Germanic languages. 'More' comes from the Old English 'māra'.

常见问题 (8)
No, 'better' is already comparative. Adding 'more' is redundant and incorrect. Just say `better`.
Double the last letter for one-syllable words that end in a single vowel and a single consonant (CVC), like `big` -> `bigger` or `hot` -> `hotter`.
In modern English, they are often used interchangeably. However, `farther` usually refers to physical distance, while `further` refers to metaphorical distance (e.g., 'further information').
Technically, 'fun' is a noun, so 'more fun' is the standard form. While you might hear 'funner' in very casual speech, it is considered incorrect in exams or formal writing.
Both are used. `Than me` is common and natural in conversation. `Than I am` or `than I` is more formal.
Yes, if they don't end in 'y'. For example, `more modern` or `more famous`. If they end in 'y', use `-ier`.
Use the structure `as + adjective + as`. For example, 'I am as tall as my brother.'
The opposite is `less`. For example, 'This book is less interesting than the other one.'
