Abstract paring and analyzing the solar and ary data of two fast halo coronal mass ejections (CMEs), we find that the CME far away from coronal holes (CHs) caused a great solar energetic particle (SEP) events, but the other one very close to CHs did not cause a major SEP events. It implies that coronal holes might suppress the production of SEPs. Further, by investigating all fast halo CMEs within a distance of $R_s$ from CHs during 1997 -- 2003, it is found that none of the CMEs produced a major SEP event. The result proves that the CHs may have effects against the CME producing SEPs. The possible reasons why CHs may prevent CMEs from producing SEPs are briefly addressed finally.
