PET阅读不低于95% - 同义词替换规律总结
PET阅读Part 5的核心考点:同义词替换
PET阅读Part 5是passage completion题,共6个空,每空需要从4个单词中选出合适的。这部分的核心就是理解同义词替换。本文从语料库中提取了200+组常考的同义词替换对,帮你快速突破这个难点。
为什么PET阅读容易失分?
问题1:不是不认识单词,而是不理解搭配
例:原文说 "The company employ many workers" 题目问:空处应该填什么 选项:A. employed B. hiring C. recruited D. promoting
大多数学生会选B(hiring),但正确答案是A(employed)。为什么?因为"employ"和"workers"的搭配频率最高。
问题2:没有掌握上下文线索
很多学生只看空句子,不看前后句。实际上,上一句或下一句往往有关键信息。
同义词替换的7大规律
规律1:动词的不同时态/形式
原型 → 过去式/过去分词/现在分词
- study → studied / studying / studied
- make → made / making / made
- walk → walked / walking / walked
实战例题:
"Last year, the school _____ a new library."
选项:A. building B. built C. builds D. to build
答案:B(根据 "Last year" 判断需要过去式)
规律2:名词的单复数变化
- problem ↔ problems
- child ↔ children
- person ↔ people
- analysis ↔ analyses
规律3:形容词与副词的转换
- quick → quickly
- beautiful → beautifully
- careful → carefully
- dangerous → dangerously
判断技巧:如果空后是动词,通常需要副词;如果空后是名词,通常需要形容词。
规律4:近义词替换
常见的近义词对:
- big ↔ large / huge
- small ↔ tiny / little
- happy ↔ pleased / delighted
- sad ↔ upset / unhappy
- interesting ↔ fascinating / exciting
- difficult ↔ hard / challenging
- easy ↔ simple / straightforward
- help ↔ assist / support
- begin ↔ start / commence
- end ↔ finish / conclude
规律5:短语替换
单个词汇 vs 多词短语
- prevent = stop from doing
- similar = the same as
- because = due to / as a result of
- need = require / be necessary
规律6:反义词的否定形式
- possible ↔ impossible
- helpful ↔ unhelpful
- clear ↔ unclear
- honest ↔ dishonest
规律7:同根词的变化
- educate → education → educational → educate
- communicate → communication → communicative → communicate
- produce → production → productive → produce
