2019职称英语综合类考试词组辨析(10)
20.certain,positive,sure 这组词均有“肯定的、确切的”之意。
certain:“确切的、肯定的”,指确信无疑或不容置疑,比sure更确定地表明有客观的理由和证据支持这种确信。主语不一定是人,常用词组:for certain 肯定;常用句型:It’scertain that…

positive:“确信的”,强调绝对相信自己言论或结论的正确性,经常表示过度的自信乃至独断之意;另处,还有“积极的、建设性的”之意。
It's no use just telling me to do it;give me positive advice as to how to do it. “仅仅告诉我做这件事是不够的,应就如何做给我一些建设性的意见。”
sure:“一定的、确信的” 强调主观上的信念或肯定,其后所跟的句型要求较为严格。常用词组:sb.be sure of/to do (对) 有把握,for sure 肯定地,sure enough 果真,to be sure当然 ( 作插入语) 。
As we have been practising regularly,we are sure of winning the game this time.“我们一直在练习,这次有把握一定赢。”
