摘要:This paper sought to find out why intonation has been neglected in the process of teaching pronunciation to EFL learners at Ho Chi Minh City University for Natural Resources and Environment (HCMUNRE) and corroborate that teaching intonation in Yes/No questions and Wh-questions to learners has positive influence on their English speaking skill. The research also suggested some useful in-class activities to teach intonation in Yes/No questions and Wh-questions to EFL learners.
