论文英文摘要中语态和时态的用法
英文摘要的字数大多数期刊规定不超过250个词,内容应与中文摘要对应。医学论文中,一般少用第一人称和主动语态,多用第三人称和被动语态,用以体现叙述客观事实。所用时态需与事情发生时间一致,叙述基本规律时可用现在时,叙述研究对象、方法和结果时,用过去时。举例如下。
Objective:The purpose of this study was to determine whether an in hospital transportable CT scanner can provide diagnostic brain images and to compare the quality of these images with those from a convertional fixed? platform CT scanner.
Subjects and Methods:Twenty seven patients with known or suspected intracranial pathology underwent imaging on a transportable scanner and a fixed? platform scanner within 1hr of each from each CT examination were evaluated independently by two neuroradiologists who were unaware of patient of intracranial pathology and normal anatomy were rated on a 5? point scale (1 point 'optimal;5 points'poor or not visualized).Statistical comparisons were made using nonparametric tests.
Results:Seven CT scans were interpreted as showing normal findings and 20 scans revealed intracranial pathology on both CT quality was higher on the fixed scanner(average rating' points'SE=)than on the transportable scanner(average rating' points'SE=(p=).Depiction of the cerebellum'midbrain'and supratentorial gray? white matter was better on the fixed scanner(p<'we found no significant differences in detection of intracranial pathology between radiologists found images from both scanners to bediagnostic in all 27 patients.
Conclusion:Images of the brain on the transportable CT scanner were less clear than those on a fixed 'images from the transportable CT scanner were diagnostic in 27 implications of this finding are important for the provision of CT services for critically ill patients who cannot be transported to the radiology department.
上面是AJR(美国放射学杂志)中一段完整的`英文摘要,从中可以看出其特点:
①用词简练、准确;
②时态为过去时;
③不用第一人称,多用被动语态;
④方法和结果中强调统计方法及数据。
对母语非英语的作者来说,撰写英文摘要的质量好坏直接与作者的英文水平有关,在这方面,只有多阅读英文文献,才能提高英文写作水平,从而写出高质量的英文摘要。

在撰写英文论文的材料与方法时应该使用过去时。
过去式(past tense)是英语语法的一种,表示过去某个时间里发生的动作或状态。一般过去式的动词通常用动词原形的过去式形式来表示,而动词的过去式是在动词原形的基础上变化的。动词的过去式可分为规则动词和不规则动词。
1.过去发生的而已经结束的动作需要用一般过去式来表示。
2.表示过去某个时间里发生的动作或状态。
【过去时态】表示行为、动作和状态在各种时间条件下的动词形式。
【过去时态结构】是指过去时态下的动词形式的语法构成。
动词变化规则:
一般动词直接加-ed,例如:look-looked;
以哑e结尾的动词直接加-d,例如:dance-danced;
辅音字母加y结尾的,变y为i再加ed,例如:study-studied;
以重读闭音节结尾,末尾只有一个辅音字母,双写这个辅音字母加-ed,例如:skip-skipped;
以c结尾的动词,要变c为ck,再加-ed;
以l结尾的动词,若以非重读音节结尾,则末尾的字母双写与不双写均可。其中不双写的是美式拼写。例如:travel-travelled/traveled(美);
部分以-p结尾的动词同样遵循第6条,这类词多由“前缀+名词”构成。例如:worship-worshipped/worshiped(美)、handicap-handicapped/handicaped(美)。
注:英语26个字母中,除了a,e,i,o,u 这几个元音字母外,其他都是辅音字母。
不规则动词变化:
动词过去式与原形相同;
动词过去式以-ought或-aught结尾的单词;
动词过去式由原形结尾的-end变为-ent;
动词过去式以-elt,-eft,-ept结尾;
动词过去式与原形比较,其中一个元音字母发生改变;
动词过去式以-ew结尾;
动词过去式-ee-变为-e-。
