❌ Chances are he has already home. (缺少介词，home用法错误)	✔ 正确：Chances are he has already gone home. / Chances are he is already home. 解析：home作为地点副词时不能直接和have连用，应使用go home或be home。💡提示：表示“到家”=go home；表示“在家”=be home
❓ “gain in” 和单独 “gain” 有什么区别？	✔ “gain”=获得某物（具体/tangible）；“gain in”=在某方面增加（抽象/quality）。例：She gained weight. / She gained in confidence. 💡提示：带“in”更偏抽象维度
❓ “aid in” 是什么意思？	✔ “aid in doing sth.”=帮助/促进做某事（正式）。相当于“be helpful in”。例：Healthy dirt aids in controlling weight. 💡提示：aid in + 动名词。Ω    
❓ “For instance”和“For example”有什么区别？	✔ 含义几乎一样，均表示举例；“for instance”略正式，“for example”最常见。例：Many sports require teamwork. For instance, football. 💡提示：两者可互换，但instance更书面
❓ “by prescription”和“on prescription”有什么区别？	✔ 二者都对。美式英语偏“by prescription”，英式英语偏“on prescription”。例：Antibiotics are only available by prescription (US) / on prescription (UK)。💡提示：记住by=美，on=英
❓ “quiver” 为什么既是“箭袋”又是“颤抖”？	✔ 因为来自不同词源：箭袋来自拉丁语“容器”，颤抖来自日耳曼语“shake”。例：He took an arrow from his quiver. / Her voice quivered with fear. 💡提示：两个词同形不同源
❓ “dispose of” 是什么意思？	✔ “dispose of sth.”=处理、丢弃（正式），也可指摆脱某人/问题。例：They dispose of hazardous waste properly. 💡提示：固定搭配=dispose of+名词
❓ 在 IT 语境中 “retrieve” 为什么既是“检索”又是“找回”？	✔ 因为retrieve本义=取回。在数据库是“检索”，在备份是“找回”，语境决定。💡提示：retrieve=“拿回来”，具体语境不同
❓ “in a pinch” 是什么意思？	✔ “in a pinch”=在必要时/紧急情况下（副词短语）。例：You can use my car in a pinch. 💡提示：想象“被掐住”=紧急情况
❓ “pinch-hit” 是什么意思？	✔ 来源棒球=“代打”，引申为临时顶替别人完成任务。例：She had to pinch-hit for her colleague. 💡提示：pinch=紧急，hit=应对
❓ “dispose” 有哪些不同用法？	✔ 1) dispose of sth.=处理；2) dispose sb to sth.=使倾向于；3) at sb’s disposal=任某人支配。💡提示：dispose后常见三个固定搭配
❓ “chances are + 从句” 是什么语法？	✔ 非正式固定表达=“很可能…”，相当于It’s likely that… 例：Chances are it will rain. 💡提示：背下来当一个整体短语
❓ 为什么说“be home”但要说“be at the office”？	✔ “home”特殊，可作副词，不加介词。大多数地点需介词at/to。例：He is home. / She is at the office. 💡提示：home是副词，office是名词
❓ “against” 为什么既是“对抗”又是“紧靠”？	✔ 抽象义=反对/对抗，具体义=紧贴/靠着。例：The ladder was placed against the wall. 💡提示：想象“压在…上”→既可以是“靠着”也可以是“反对”
❓ “distinction” 可以看作“different”的书面版吗？	✔ 不完全。distinction=区别（名词），different=不同的（形容词）。例：The law makes a distinction. / They are different. 💡提示：词性不同，不能互换
❓ “ignite”和“light” 都表示点燃，有什么区别？	✔ ignite=正式/强烈/可比喻；light=日常/普通动作。例：The gas ignited. / He lit a candle. 💡提示：ignite=爆炸/抽象，light=日常/具体
❓ “arrive in”和“arrive at” 有什么区别？	✔ arrive in=大地方（国家/城市）；arrive at=小地点（机场/车站/建筑）。例：Arrive in Beijing / Arrive at the airport。💡提示：大地方in，小地方at
