很多人做阅读有一个惯性:题目里看到 because of,手指直接扫向原文找 because。找不到就反复扫,找到了就觉得答案稳了。
出题人不可能让你每次都用原词定位。一道题写的是 because of,原文可能写的是 on the understanding that;一道题问 the causes lie in the environment,对应的原文直接用了 due to。你今天在题干里扫到的因果连接词,在原文里大概率会被改写成一个条件结构、一个目的状语、一个分词短语,或者干脆塞进一个动词里。
下面用四组真题,把这三类因果替换拆开,给你一套可以直接套用的定位步骤。
题目写 because of,原文会不会写 because?
剑 9 Test4 Passage 1 Q3 是一道判断题,题干说:
Marie was able to attend the Sorbonne because of her sister's financial contribution.
很多考生第一反应是去原文找 because of,结果遍寻不着。答案句其实在两句话里:
"From her earnings she was able to finance her sister Bronia's medical studies in Paris, on the understanding that Bronia would, in turn, later help her to get an education."
原文没有 because,也没有 because of,用的是 on the understanding that… would, in turn…,一个双向承诺结构——Marie 先出钱送姐姐学医,姐姐承诺将来回报她上学。题干把两个方向的因果压缩成单向的 because of,但核心事实一致,判为 TRUE。
同篇 剑 9 Test4 Passage 1 结尾也有一段直接用了 because of:
"because of her influence on subsequent generations of nuclear physicists and chemists"
但这个 because of 不出现在任何一道题的题干里。出题人如果要考这一个点,大概率会把这句话改写为 Her work shaped the research of later physicists,用动词 shape 替换掉因果连接词。
这一组真题说明了第一条替换规律:题干主动使用 because of,原文往往是一个条件句、一个目的状语、或者两个动作之间的先后逻辑。 定位时不要只扫 because,要同时盯住 in order to、so that、on the condition that、in response to 这些信号。
due to 的方向陷阱
J4 Test1 Passage 2 Q22 是一道人物观点配对题,题干陈述写:
The causes of multitask lie in the environment.
对应的原文归属句是:
"Edward Hallowell said that people are losing a lot of efficiency in the workplace due to multi-tasking, outside distractions and self-distractions."
原文直接用了 due to,但题干把 due to 改成了 "causes lie in",把原文分散的 outside distractions、self-distractions 概括成了 environment。
due to 有一个很多人踩过的方向性陷阱:due to X 中,X 是原因,due to 前面的部分是结果。 原文说 losing efficiency due to distractions,因果关系是 distractions → efficiency loss。题干说 causes lie in the environment,方向完全一致,但连接词从 due to 变成了 causes lie in。
如果你做题时只认 due to 这三个字母,看到题干没有 due to 就判定“没证据”,这道题大概率会丢。反过来,如果你拿到一个句子,快速把 due to 替换成“的原因是”读一遍,方向对不对立刻就能判断。
as a result 抓的不是词,是前后两句
剑 20 Test1 Passage 1 讲新西兰鸮鹦鹉的保护历史,原文出现了非常清晰的因果链:
"predation by feral cats on Rakiura Island led to a rapid decline in kākāpō numbers. As a result, during 1980–97, the surviving population was evacuated to three island sanctuaries..."
这里 led to 给第一层因果(野猫捕食 → 种群数量骤降),As a result 引出第二层因果(数量骤降 → 转移到三个岛屿保护区)。两个因果标记直接串连成链。
as a result 在雅思阅读里几乎没有例外的使用模式:前面句子是原因,后面句子是结果。 题目通常会把 as a result 前后的信息压缩到一道题里,删掉中间的连接词,让你判断正误或补全填空。
你的定位步骤应该是三步:第一,看到题干里出现了 result、consequence、outcome 这一类概括性词,立刻意识到原文很可能有一段明确的因果链;第二,回原文找到原因句和结果句,哪怕中间没有 as a result,只要逻辑通就行;第三,比对题干是用什么词替换了原因和结果——因为它大概率不会原样保留。
最隐蔽的因果:动词里藏着
剑 9 Test3 Passage 3 Q27 是一道段落信息匹配题,题干要找一个段落,内容包含 "an explanation of the factors affecting the transmission of the information"。原文对应句是:
"This rate depends on the relative strengths of the signal and noise travelling down the communication channel, and on its capacity (its 'bandwidth')."
题干里的 factors affecting 来自原文的 depends on。depends on → factors affecting,一个是“依赖于”,一个是“影响……的因素”,因果方向一致,但前者是动词短语,后者是名词短语。
真题里同一类替换反复出现:
- cause / lead to / result in → bring about / trigger / be responsible for
- allow / enable → make possible / facilitate / pave the way for
- arise from / stem from → be attributed to / be driven by / have its origins in
定位时如果只认 because、due to、as a result,你会漏掉至少一半的因果考点。动词才是出题人最常用的改写工具。
三条可以立刻上手的规则
规则一:题目里的因果词,原文大概率不会原样出现。 题目写 because of,去原文找 on the understanding that、in response to、given that,或者干脆找两个动作之间的先后逻辑。
规则二:因果方向不能颠倒。 拿到一个因果句,把你怀疑是原因的部分代入“的原因是”读一遍,通顺就对,卡住就反。
规则三:不要只盯连接词。 depends on、affects、shapes、drives、enables——这些动词本身就在说“谁导致了谁”。你的任务不是翻译句子,是识别因果方向。
