2026年6月英语六级第2套真题句子解析： Researchers found that people who filled out this sentence were two to three times more likely to actually exercise compared to a control group who did not make plans for their future behavior.

that people who filled out this sentence were two to three times more likely to actually exercise compared to a control group who did not make plans for their future behavior

主句是 "Researchers found that..."，其中宾语从句由 "that" 引导；宾语从句内部，主语 "people" 后有定语从句 "who filled out this sentence"，说明哪些人；谓语部分包含 "to actually exercise" 不定式；句末的 "a control group" 后又有定语从句 "who did not make plans for their future behavior"。因此形成“主句—宾语从句—定语从句/不定式—另一处定语从句”的多层嵌套，主干容易被修饰成分分割。

people who filled out this sentence were two to three times more likely to actually exercise compared to a control group who did not make plans for their future behavior

宾语从句的主干是 "people were ... more likely to exercise"。主语中心词 "people" 后先插入较长的定语从句 "who filled out this sentence"，谓语 "were" 被推迟；谓语后的比较结构和另一个定语从句又继续延长句子。主语与谓语之间的修饰成分使核心结构不易迅速识别。

to actually exercise

"were" 后接 "two to three times more likely"，其中 "likely" 是形容词，表示“可能的”；"to actually exercise" 是不定式短语，补充说明这些人“更有可能做什么”，构成 "be likely to do" 结构。因此这里的不定式作主语补足语（表语），而不是表示目的的状语。

were two to three times more likely to actually exercise

"be likely to do" 是固定搭配，意为“可能做某事”，其中 "be" 是系动词，随主语时态变化；"likely" 是形容词；后接带 "to" 的不定式。

本句在 "be" 和 "likely" 之间插入了程度短语 "two to three times more"，这是允许的修饰，不改变框架本质；"to actually exercise" 中的 "actually" 修饰 exercise，也不影响搭配。

可迁移方法：识别 "be + 形容词 + to do" 时，先确认形容词是否与 "to do" 构成固定语义（可能、愿意、倾向等），再判断 "to do" 是否为目的状语；可插入副词或程度短语，但核心框架不变。

two to three times more likely

识别倍数比较的关键是先找“倍数词 + 比较结构”的组合，例如本句中 "two to three times" 是倍数词，"more likely" 是比较级。

本句没有用 "than" 而是用 "compared to" 引出比较基准，这是常见变体，但核心仍是倍数修饰比较级，表示“可能性是……的两到三倍”。

可迁移方法：看到 "times" 先判断是否表示倍数而非次数；再找其后紧邻的比较级、原级或名词所有格结构；最后确认比较基准由 "than"、"as" 或 "compared to" 引出。
