What is being practised if a teacher asks students to read words like “cot, hot” and “dog, log”?
A Spelling and structure.
B Stress and sound.
C Minimal pairs.
D Phonetic symbols.
回答错误
你的答案:
参考答案:C
解析:
在音位分析中，只涉及一个音素差别的对立体叫作最小对立体。题目中的cot与hot，dog与log两组词都只有一个音素的差别，该教师让学生通过最小对立体（minimal pairs）分析音差，进行辨音练习。

故选项 C正确。
