🔊 发音指导
can only:/kæn ˈəʊnli/ [kæn ˈoʊnli]
have to:/hæv tə/ [hæv tə]
must:/mʌst/ [mʌst]
发音要点:
- "can only"中"can"发短音,"only"重音在第一个音节
- "have to"在日常口语中常读作"hafta"

- "be only able to"中"able"重音在第一个音节
中文谐音参考:
can only:看-欧恩利
have to:哈弗-图
must:马斯特
💡 顾老师纠音:常见发音错误:
- 错误1:把"can only"读成"肯欧利"(正确:[kæn ˈoʊnli])
- 错误2:忽略"have to"的连读现象
- 错误3:把"must"读成"穆斯"(正确:[mʌst])
