Paraphrase
分析词义
- X-ray 是一种电磁辐射,通常用于医疗成像和结构分析。词义有两个,一是作为名词,表示“X射线”,在医学上主要用于影像检测,比如"X-ray examination"(X射线检查);二是作为动词,表示“用X射线照射”,如"The doctor x-rayed the patient's chest."(医生对病人的胸部进行了X射线检查)。
列举例句
- The doctor decided to take an X-ray to check for broken bones.(医生决定拍摄X光片以检查是否有骨折。)
- Can X-ray radiation cause cancer? (X光辐射会导致癌症吗?)
- She had her luggage X-rayed at the airport. (她在机场让行李通过了X光检查。)
词根分析
- "X"在此处是代表未知的符号,"ray" 来自拉丁词根 "radius",意为“光线、射线”,因此,“X-ray”即表示“未知的射线”。
词缀分析
- 此词无前后缀。"X"和"ray"合并形成单一词汇,无需进一步分析。
发展历史和文化背景
- "X-ray"在医学成为常用词汇是在1895年,由德国物理学家威廉·康拉德·伦琴首次发现并命名。"X"表示未知,因为当时这种射线的性质未被完全理解。"X-ray"在英式英语中有时被称为 "Rontgen ray",以表彰伦琴对其的贡献。
单词变形
- 名词:X-ray
- 动词:X-ray, X-rayed, X-raying
- 名词再次使用:X-ray machine (X射线机), X-ray technician(X射线技术员)
记忆辅助
- 可以将 "X-ray" 与 "X" 形状的物体关联起来,如 "X" 形状的支架(在医院中常见),或者将 "ray" 与阳光的射线关联,以此来帮助记忆。
