非英语母语作者经常提交语法无误、但选词存在问题的稿件。问题不在于研究本身不扎实，而在于某些词汇会向审稿人传递不精确、过度自信或逻辑混乱的信号，削弱原本可信的结论。
这五类误用词在各个职业阶段的稿件中都会反复出现。每一节包含具体的替换策略，以及修改前后的改写对比。
一、过度确定性词：prove、confirm、demonstrate
prove、confirm、demonstrate 这类词断言某个假设已被确立为事实。在大多数实验语境中，这种表述并不成立。单项研究只能支持或提示某个结论，不能”证明”它。受过科学训练的审稿人一看到这类词，往往会立刻产生警觉，认为作者对自身证据的局限性缺乏认识。
demonstrate 属于一个特殊子类：用于描述某种方法、图表或操作步骤所展示的内容时，它是可以接受的，但不能用来描述统计结果或研究结论。“Figure 2 demonstrates the distribution of responses” 没有问题，而 “these results demonstrate that the drug is effective” 则超出了数据所能支撑的范围。在后一类语境中，标准替换词是 show。
过度表述（错误）：
These results prove that the intervention reduces inflammatory markers in patients with type 2 diabetes.
The data confirm that early intervention improves prognosis.
修改后：
These results suggest that the intervention may reduce inflammatory markers in patients with type 2 diabetes.
The data support the view that early intervention improves prognosis.
改写对比：
修改前:
Our findings confirm that higher vitamin D levels lead to better surgical outcomes.
修改后:
Our findings indicate that higher vitamin D levels are associated with better surgical outcomes.
二、因果混淆词：cause、lead to、result in
因果性语言表示一个变量直接产生另一个变量。这种表述需要随机对照试验或设计严谨的机制实验作为支撑。观察性研究、队列研究和横断面研究只能建立关联，而非因果关系。在观察性研究的语境中使用 cause、lead to 或 result in，会被审稿人指出，有时甚至成为直接拒稿的理由。
断言因果（错误）：
Increased sedentary time causes higher fasting glucose levels in middle-aged adults.
Stress leads to elevated cortisol secretion in this patient population.
修改后（观察性研究语境）：
Increased sedentary time is associated with higher fasting glucose levels in middle-aged adults.
Stress is linked to elevated cortisol secretion in this patient population.
改写对比：
修改前:
The mutation leads to impaired mitochondrial function and subsequent cell death.
修改后:
The mutation is linked to impaired mitochondrial function and subsequent cell death.
注意：如果研究设计支持因果推断（例如，具有充分证据的机制实验），因果性语言可能是合适的。此替换策略主要适用于观察性研究。
三、统计词误用：significant、insignificant
significant 有两种含义，且经常被混淆。在日常英语中，它表示”重要的”或”显著的”；在统计学语境中，它表示结果跨越了预设的阈值（通常为 p < 0.05）。不加限定地使用 significant，会让读者无法判断作者指的是哪个含义。
insignificant 的问题更大。它暗示该发现毫无价值，这是一种科学判断，而非统计学陈述。一个未达到统计显著性的结果，仍然可能具有临床意义、能够产生新假设，或对未来的荟萃分析有参考价值。正确的表述应描述统计结果本身，而不对研究价值做出评判。
表述模糊或错误：
The difference in mortality rate was insignificant between the two groups.
We observed a significant improvement in quality of life scores.
修改后：
The difference in mortality rate did not reach statistical significance between the two groups (p = 0.12).
We observed a statistically significant improvement in quality of life scores (p = 0.03), with a mean increase of 8.2 points on the SF-36 scale.
改写对比：
修改前:
The effect of treatment on biomarker levels was significant and the placebo effect was insignificant.
修改后:
The effect of treatment on biomarker levels was statistically significant (p = 0.01), while the placebo group showed no statistically significant change (p = 0.43).
中文母语作者还有一类常见误用：把 p 值大小等同于效应量大小，例如写”p = 0.001，因此效果极为显著”。p 值仅反映统计显著性，不反映效应大小。效应量需通过 Cohen’s d、odds ratio、hazard ratio 等单独报告。
四、比较词误用：compare to、similar、different
比较语言中存在三类相关错误。
第一类：compare to 与 compare with 的混用。在科学写作中，比较两件事物的差异应使用 compare with，这是标准用法。Compare to 是一种修辞结构，用于类比两种事物。绝大多数科学比较需要 compare with。
第二类：similar 和 different 后面缺少介词。这两个词在语法上都需要跟介词才能完整表达比较关系，即 similar to 和 different from。写 “the results were similar” 或 “the expression was different”，在正式学术写作中会被视为表述不完整，读起来像是一个错误。
错误：
We compared the outcomes of technique A to technique B.
The expression levels in the treatment group were similar and different compared to the control group.
修改后：
We compared the outcomes of technique A with those of technique B.
The expression levels in the treatment group were similar to those in the control group at baseline but different from those at week 12.
改写对比：
修改前:
Survival rates were similar in both groups, but complication rates were different.
修改后:
Survival rates were similar between both groups (82.1% vs. 83.4%), but complication rates were different between the laparoscopic group (14.2%) and the open group (6.8%).
五、程度副词滥用：dramatically、extremely、very、highly
程度副词以放大声明的方式出现，效果却适得其反，反而削弱可信度。Dramatically 带有戏剧性色彩，不适合科学报告。Extremely 和 very 是口语化的强调词，属于日常用语，而非学术稿件的语言。Highly 则被过度使用，“highly significant”、“highly effective” 在文献中重复出现过于频繁，已经失去了精确传达信息的能力。
最有效的策略是用具体数据替代副词。当定量比较数据不可得时，markedly、substantially、considerably 等中性替代词是合适的选择。
表述非正式或不精确：
The treatment dramatically improved survival rates in the experimental group.
Protein expression was very high in tumor samples.
修改后：
The treatment markedly improved survival rates in the experimental group (hazard ratio 0.42, 95% CI 0.31-0.57).
Protein expression was substantially higher in tumor samples than in normal tissue (mean fold change: 4.7).
改写对比：
修改前:
Inflammation markers were extremely elevated in the treatment group, and the drug response was very rapid.
修改后:
Inflammation markers were substantially elevated in the treatment group (mean CRP 48.3 mg/L vs. 12.1 mg/L in controls), and the drug response was rapid (median time to response: 3 days).
提交前的自查清单
- 你有没有用 prove、confirm 或 demonstrate 描述实验结果？替换为 support、suggest 或 indicate。
- 你的研究设计能支持因果推断吗？若为观察性研究，将 cause、lead to、result in 替换为 associated with 或 linked to。
- 每处 significant 是否都明确指统计显著性？有没有 insignificant 需要替换为 did not reach statistical significance？
- compare 后面用的是 with 还是 to？similar 和 different 后面有介词（to 和 from）吗？
- 有没有 dramatically、extremely 或 very 可以替换为具体数据或更精确的副词？
本文所述的选词问题，正是专业稿件编辑能发现而作者容易忽视的一类错误，原因恰恰在于：作者清楚自己想表达什么，反而不容易察觉措辞的偏差。
