摘要
The present study is a comparison study of research instrument in the field of interlanguage pragmatics. Sixty-two Chinese EFL university students participated in the study. Written DCT and oral role-plays were designed in four stimulus types of refusal strategies--refusals to invitations, suggestions, offers and requests. Chi-square test and frequency were used for quantitative data and transcription of the tests was used for the qualitative data. The results show that there is no significant difference between the two tests in terms of strategies choices, but written DCT can produce a longer sentence while oral role-plays can yield a more natural expression.
