Commonly Confused and Misused Words
常见易混易错单词
1 不定冠词a/an 与定冠词the
• “a/an”: 用于可数或单数名词之前
例:"A new species of Escherichia was identified.“
(other species also exist)
•“the”: 指目前或将来独一无二事物
例:" The organism responsible for the outbreak was Escherichia coli."
2 affect/effect (and impact)
• “effect”作为名词时,表示“行为的结果”
• “affect ”作为动词时,意思为“影响”
BUT
• “effect” 作为动词时,意思为“引起变化”
• “affect” 作为名词时,意思为由于某人行为举止或语言引起的感受或情绪
• “impact” 只用于描述“一件事对另一件事”产生的冲击,不能作为“affect”使用

(influence the recovery in some way)
例:“Ingesting massive doses of ascorbic acid may effect his recovery.”
(produce/cause the recovery)

3 because/as/since
• “as” 表示时间,而不是因果关系
例:“As we were completing the paper, new evidence came to light.”
• “because” 表示因果关系
例:“Five participants could not complete the follow up questionnaire because they had moved out of the target district.”
• “since” 表示时间关系
例:"Since we completed the study, there have been 3 additional outbreaks."
4 because of/due to
• “due to” = adjective + preposition, adjectival phrase meaning “attributable to” or “caused by” 归因于…
例:"The problem was due to mechanical failure."

• “comparable”: 可与…相比的, 类似的
例:“Because the methods are different, the statistics are not comparable.”
• “similar”: 相似

* “Same” 有时会与 “ similar” 混淆。 “Same” 指完全一样,或 “identical”,通常不用于科研结果的比较 , 特别是两项不同研究的比较
6compose/comprise/constitute
• “compose”
*1) 构成,主动语态
例:“Fifty states compose the United States of America.”
* 2) 构成,被动语态
例:“The United States of America is composed of 50 states.”

* 如不单纯表示统计学意义,建议使用其它单词
