The present research reports a comparative study on the use of ＂really＂ by Chinese EFL learners. Taking the perspectives colligation and collocation, the study mainly yields the following findings： （1） Compared with American native speakers, Chinese EFL learners have different preferences for colligations and collocations of ＂really＂; （2） High achievers and low achievers demonstrate a similar pattern of the ranking order of the colligations, but high achievers are closer to the native speakers in the use of ＂really＂ in terms of collocation; low achievers rely more heavily on ＂very＂ to collocate with adjectives than high achievers.
