专项讲解与练习题
语法1:后缀 -er/-or/-ian/-ist(表职业/身份)
讲解
- 定义:通过在动词、名词后添加特定后缀,构成表示“从事某职业/具备某身份的人”的名词,是英语中构词的常见方式。
- 后缀分类、适用词类及例词
后缀 | 适用词类 | 核心含义 | 例词(原词→派生词) |
-er | 短动词(多为单音节) | 做某动作的人 | work→worker(工人)、write→writer(作家)、play→player(运动员) |
-or | 动词(多为拉丁语词根,以“t/s”结尾) | 做某动作的人 | act→actor(演员)、visit→visitor(游客)、direct→director(导演) |
-ian | 学科/国家名词 | 某领域从业者/某国人 | music→musician(音乐家)、history→historian(历史学家)、Canada→Canadian(加拿大人) |
-ist | 学科/主义名词 | 某学科/主义的从业者 | art→artist(艺术家)、science→scientist(科学家)、communist→communist(共产主义者) |
- 核心考点
○ 以“e”结尾的动词,加后缀时需去掉“e”:如drive→driver(司机)、write→writer(作家)。
