雅思口语词汇：哪些词能帮你拿到Band 7+
Band 7的词汇要求是"灵活使用不太常见的词汇"并"了解搭配和语体"。这并不意味着你要背一堆生僻词——而是要学会在合适的语境中，用更精准、更高级的词替换那些过于简单的基础词。
词汇升级原则
不要漫无目的地背单词。最有效的方法是：找到你常用的基础词，学习它们的高级替换。
| Band 5-6 用词 | Band 7+ 替换 | 使用语境 |
|---|---|---|
| good | remarkable, outstanding, beneficial | "It was a remarkable experience" |
| bad | detrimental, concerning, problematic | "This could be detrimental to health" |
| very big | substantial, considerable, significant | "A substantial number of people" |
| very important | crucial, essential, paramount | "Education is essential for development" |
| a lot of | a considerable amount of, numerous | "Numerous studies have shown..." |
| think | believe, consider, reckon | "I firmly believe that..." |
| like | be fond of, be keen on, be passionate about | "I'm quite keen on photography" |
| very happy | thrilled, delighted, ecstatic | "I was absolutely thrilled" |
注意：不是所有场合都适合用高级词。在Part 1轻松的聊天氛围中，偶尔用1-2个高级词就够了。在Part 3讨论社会话题时，可以更多地展示高级词汇。

词汇搭配（Collocations）：让你听起来更自然
搭配用错比用错单词更暴露你的水平。以下是中国考生最常犯的搭配错误：
| 错误搭配 | 正确搭配 |
|---|---|
| do a mistake | make a mistake |
| do progress | make progress |
| big traffic | heavy traffic |
| strong rain | heavy rain |
| open the light | turn on the light |
| close the light | turn off the light |
| play computer | use a computer / play computer games |
如何高效积累词汇
- 在语境中学习——不要死背单词表。从文章、播客、对话中学习新词，这样你不仅知道词义，还知道怎么用。
- 学习搭配而不是单个词——"heavy rain"比单独学"heavy"有用得多。每学一个新词，同时学2-3个搭配。
- 学了马上用——今天学了"detrimental"，今天练习口语时就要用上。不用的词会很快忘记。
- 每天5个词——质量比数量重要。5个真正掌握的词 > 20个只认识但不会用的词。
- 每周复习——准备一个词汇本，每周日花15分钟回顾本周学的词。用间隔重复法（spaced repetition）效果更好。
词汇使用的常见误区
- 为了炫技堆砌大词——如果你用了一个自己不确定的词，用错了反而扣分。不确定就用你会的词。
- 每句话都用高级词——自然的语言是高级词和普通词的混合。满嘴大词听起来像在念学术论文。
- 中式英语直译——很多中文表达直译成英文是不地道的。比如"学到了很多知识"不说"learned many knowledges"（knowledge不可数），而说"gained a lot of knowledge"。
