讲清楚它是什么

定义 推理判断是根据文中已知信息,运用逻辑推导得出文中未直接陈述但必然存在的结论的过程。

从哪来 它建立在1.1 什么是长难句之上。只有准确拆解长难句,厘清主谓宾及修饰关系,才能提取出用于推理的核心事实依据,避免被复杂句式干扰逻辑链条。

为什么 阅读理解的本质是“信息重构”。文章受篇幅限制,作者往往只呈现“事实(Fact)”或“现象(Phenomenon)”,而将“原因(Cause)”、“动机(Motivation)”或“隐含态度(Attitude)”留白。推理判断就是填补这一空白。若缺乏逻辑推导,学生只能停留在字面意思,无法理解文章深层逻辑;若推导过度,则会陷入主观臆断。因此,必须基于文本证据进行有限度的逻辑延伸。

适合:逻辑思维强、喜欢规则的学生** 采用“证据链模型”。告诉学生:推理 = 文本证据 + 逻辑常识。 1. **找锚点
在文中定位题干关键词,找到支撑该题的1-2个关键句(Evidence)。 2. 搭桥梁:运用常识或上下文逻辑,连接证据与选项(Bridge)。 3. 得结论:看哪个选项是证据的必然结果,而非可能结果。 *口诀*:“无据不推,有据必推,推而不越。”
适合:语感好、但逻辑易跳跃的学生** 采用“侦探破案法”。 1. **角色代入
假设你是侦探,文章是案发现场,选项是嫌疑人。 2. 排除法: - 嫌疑人A(无中生有):文中完全没提,排除。 - 嫌疑人B(张冠李戴):把甲的事安在乙头上,排除。 - 嫌疑人C(过度推断):虽然可能,但文中没证据,排除。 - 嫌疑人D(合理推断):文中线索指向他,且符合常理,锁定。 *重点*:强调“文中没说的不能选”,哪怕你觉得很有道理。
适合:基础薄弱、畏惧长难句的学生** 采用“翻译+简化法”。 1. **降维打击
先不急着做题,把包含推理线索的长难句翻译成中文。 2. 剥离修饰:去掉形容词、副词、从句,只保留“谁+做了什么+结果如何”。 3. 常识验证:用中文逻辑判断,如果中文读起来觉得“作者肯定想表达这个意思”,再回看选项。 *核心*:先确保读懂了字面意思,再谈逻辑,避免因为看不懂句子而瞎猜。

基础题
Text:* "The new policy has been implemented for three months. During this period, traffic congestion in the city center has decreased by 20%, and air quality has improved significantly. However, some residents complain that the construction of the new bike lanes has caused temporary inconvenience." *Question:* What can be inferred from the passage? A. The new policy is a complete failure. B. The new policy has brought both benefits and drawbacks. C. Residents are against the new policy. D. Traffic congestion has disappeared completely.
变式
Text:* "In the 19th century, most people believed that the earth was flat. However, Magellan's expedition proved that the earth was round. Despite this scientific evidence, many religious leaders continued to teach that the earth was flat, arguing that the Bible did not explicitly state the shape of the earth." *Question:* Why did religious leaders continue to teach that the earth was flat? A. They did not know about Magellan's expedition. B. They prioritized religious texts over scientific evidence. C. They were afraid of the public. D. They thought Magellan was lying.
看解答过程
1. 提取证据:文中提到“traffic congestion... decreased by 20%”(拥堵减少,好处)和“air quality... improved”(空气质量改善,好处);同时提到“residents complain... temporary inconvenience”(居民抱怨暂时不便,坏处)。 2. 逻辑推导:政策既有正面效果(拥堵减少、空气变好),也有负面反馈(施工带来不便)。 3. 选项分析: - A项“complete failure”与“decreased by 20%”矛盾,排除。 - C项“against”过于绝对,文中仅说“complain about temporary inconvenience”,未说反对政策本身,排除。 - D项“disappeared”与“decreased by 20%”矛盾,排除。 - B项“both benefits and drawbacks”准确概括了文中的正反两方面信息。

检测题
*Text:* "The company announced a 10% salary cut for all employees to survive the economic downturn. Most employees accepted the decision, understanding that it was better than losing their jobs entirely. However, the CEO received a letter from a shareholder demanding immediate resignation, claiming that the salary cut was a sign of poor management." *Question:* What can be inferred about the CEO's situation? A. The CEO will definitely resign. B. The CEO faces internal support but external pressure. C. The CEO is unpopular with all employees. D. The company will go bankrupt soon.
看答案和判分标准
答案:B
判对标准:
- 选B且能指出:文中“Most employees accepted”代表内部支持;“shareholder demanding... resignation”代表外部压力。
- 若选A,需指出文中仅说“demanding”,未说CEO“will resign”,属于过度推断。
- 若选C,需指出文中说“Most employees accepted”,并非“all”,且未提及不受欢迎,属于以偏概全。
- 若选D,需指出文中说“to survive”,说明公司还在努力生存,未断定破产,属于无中生有。
