句型公式

句型公式例句
比较级A + be + 比较级 + than + BLondon is bigger than Paris.
最高级A + be + the + 最高级 + in/ofShe is the tallest girl in our class.
一样A + be + as + 原级 + as + BTom is as tall as his father.
不一样A + be + not as + 原级 + as + BI’m not as fast as you.

Grammar Lens

最高级必须加 the ⚠️

✅ She is THE tallest in the class.
❌ She is tallest in the class.

但副词最高级可以省略 the：He runs (the) fastest in our team.

in vs of ⚠️

in + 范围/地点of + 群体/数量
the best student in the schoolthe best of all the students
the biggest city in Chinathe youngest of the three brothers

比较级强化词

词含义例句
much / far / a lot大得多He is much taller than me.
a little / slightly稍微She is a little older than her sister.
even甚至更Today is even colder than yesterday.

Trap ❌ 不能说 more taller 或 most tallest——已经加了 -er/-est 就不能再加 more/most。

😂 Grammar Joke

比较级的哲学问题

Teacher: “Give me the comparative of ‘good’.” Student: “Better.” Teacher: “And the superlative?” Student: “Best.” Teacher: “And the comparative of ‘bad’?” Student: “Worse.” Teacher: “And the superlative?” Student: “My exam results.”

老师问 bad 的最高级，标准答案是 worst。 但学生说”我的考试成绩”——这比 worst 还 worst。

语法点：good → better → best，bad → worse → worst 是两组最重要的不规则比较级。注意：不能说 more good 或 most bad。

🏛 语言文化光点

世界之最——用最高级游历地球

The Nile is the longest river in the world.（尼罗河，6,650 km） Mount Everest is the highest mountain on Earth.（珠穆朗玛，8,849 m） Russia is the largest country in the world.（俄罗斯，1,710万 km²） The cheetah is the fastest land animal.（猎豹，120 km/h） Vatican City is the smallest country in the world.（梵蒂冈，0.44 km²）

KET 阅读理解经常出现地理和动物的比较——记住这些事实，既学语法又长知识。

🔵 The World’s Most Extreme Places

The Sahara Desert is hotter than any other desert on Earth — temperatures can reach higher than 50°C. But it is not the largest desert. Antarctica is actually bigger than the Sahara, and it is also the coldest place in the world, with temperatures lower than minus 80°C. The Mariana Trench is the deepest point in the ocean — deeper than Mount Everest is tall. And the Amazon rainforest has more species of plants and animals than any other place on the planet.

🔵 Messi vs Ronaldo: The Greatest Debate

Who is better — Messi or Ronaldo? Messi is shorter than Ronaldo (170 cm vs 187 cm), but many fans say he is the most talented player ever. Ronaldo is faster and stronger, and he has scored more goals in the Champions League than anyone else. Messi has won more Ballon d’Or awards — eight, which is the most in history. Ronaldo’s fans say he works harder and trains more seriously than any other player. The truth? Both are the greatest of their generation. Football has never seen anything more exciting than this rivalry.

🔵 iPhone vs Android: Which Is Better?

iPhones are usually more expensive than Android phones. The cheapest iPhone costs about 200. Apple fans say iPhones are easier to use and have better security. Android users say their phones are more customizable and offer more freedom. The screens on Android phones are often larger than iPhone screens. But iPhones tend to last longer. In the end, the best phone is the one that works best for you.
