study published in September suggests there is a surprising way to get people to avoid unhealthy food: change their memories. Scientists asked volunteers to answer some questions on their food experiences. One week later, having fed the people, they told them to type their answers into a smart computer. Having told them that they had got sick after eating strawberry ice cream, the researchers then changed this detail into a manufactured memory through leading questions. Up to 41% of those given a false memory believed strawberry ice-cream once made them sick, and many said they'd avoid eating it. 分词的分类与功能概览： 单元语法 分词类型 形式 核心含义 句中功能 现在分词 doing / having done 主动、进行 定语、状语、宾补、表语 过去分词 done 被动、完成 定语、状语、宾补、表语 【要点】：分词在真实语境中无处不在，掌握分词是读懂长难句、写出高级句式的关键。 语态对比：主动 vs 被动 核心对比——现在分词 vs 过去分词 单元语法 对比维度 现在分词 (doing) 过去分词 (done) 语态 表示主动关系 表示被动关系 时间 表示正在进行的动作 表示已经完成的动作 示例 falling leaves 正在飘落的树叶 fallen leaves 已经落下的树叶 示例 developing country 发展中国家 developed country 发达国家 示例 boiling water 正在沸腾的水 boiled water 已经烧开的水 情感类动词的分词用法： 单元语法 分词类型 修饰对象 含义 示例 现在分词 (-ing) 修饰物 “令人……的” an exciting movie 令人激动的电影 过去分词 (-ed) 修饰人 “感到……的” an excited audience 感到激动的观众 【记忆口诀】：-ing常主动，正在进行中；-ed常被动，完成是特征；事物令人-ing，人感-ed在心中。 分词的四大句法功能 单元语法 句法功能 用法说明 现在分词 (doing) 过去分词 (done) 作定语 修饰名词，相当于定语从句 The man standing there (＝who is standing there) is my teacher.
