* 避免使用“For the first time”等类似的优先权声明。 在讨论中应选择适当的词汇来区分推测与事实。例如，可选用“prove”，“demonstrate”等表示作者坚信观点的真实性；选用“show”,“indicate”,“found”等表示作者对问题的答案有些不确定性；选用“implay”，“suggest”等表示推测；或者选用情态动词或副词“can”，“will”，“should”，“may”，“could”，“probably”，“possibly”等来表示论点的确定性程度。 * 4.4.3 讨论的表达与时态 4.4.3.1 回顾研究目的 回顾研究目的时，通常使用过去时。如： This research investigated the effects of two different learning methods. In this study , the effects of two different learning methods were investigated. We originally assumed that worker who enjoy a greater degree of privacy would be more satisfied with their jobs . * 4.4.3.2 概述重要结果 如果作者认为所概述结果的有效性只是针对本次特定的研究，需用过去时；相反，如果具有普遍的意义，则用现在时。如： In the first series of trials , the experimental values were all lower than the theoretical predictions. Our findings are in substantial agreement with those of Smith(1985) The experimental and theoretical values for the yields agree well . * These results contradict(are consistent with) the original hypothesis . —Tom identified a catalyst that increases the yield at high temperatures. —Slinger identified a catalyst that increased the yield at high temperatures. * 4.4.3.3 说明结果或阐述相关推论 （1）说明结果时多采用主从复合句的形式，主句动词多为表示可能性的现在时动词，从句中的动词为现在时表示说明具有普遍意义，从句中的动词若为过去时则说明结果的范围只适于本次的特定研究。如： It is possible(may be, is likely) that adding water causes the reaction rate to increase. These results can be explained by assuming (This inconsistency indicates) that adding water caused the reaction rate to increase. * (2)阐述由结果得出的推论时，通常使用现在时，使用现在时的理由是作者得出的是具普遍有效的结论或推论，而不只是在讨论自己的研究结果，并且结果与结论或推论之间的逻辑关系为不受时间影响的事实。如： The data reported here suggest(These findings support the hypothesis; Our data provide evidence) that the reaction rate may be determined by the amount of oxygen available . The reaction rate may be determined by the amount of oxygen available. The reaction rate is determined by the amount of oxygen available. * 4.4.3.4 研究方法或结果的局限性及相关建议 （1）指出研究局限时，应使用的时态视句子的内 容而定 如果是关于作者已完成的研究事实，应使用过
