剑桥PET词汇
Instead of memorizing isolated words, we connect them through five visual and logical layers.
One root helps you unlock an entire word family.
act → action / active / interact
Use the A+B=AB pattern to build new words from familiar pieces.
note + book = notebook
A↔B contrast makes meanings sharper and easier to retain.
increase ←→ decrease
Master common prefixes and suffixes to infer unfamiliar words.
im- + possible = impossible
Put words back into real-life scenes so they are easier to recall and use.
Airport → gate / baggage / boarding
我们按词根组、词缀组、场景主题组、复合词组、反义词组五条主线来整理。
除了分组逻辑，还加入公共字母组合高亮、思维导图、A+B=AB、A←→B 等视觉设计，让记忆更牢。
