班级 姓名 学号 分数 Unit 8 Once upon a Time 一般过去时与一般现在时的区别 （时间：60分钟，满分：100分） 一、核心区别总结 对比维度 一般过去时 一般现在时 时间概念 描述过去某个时间发生的动作或过去存在的状态 描述现在发生的动作、习惯性行为或客观真理 动词形式 动词用过去式（规则动词加-ed，不规则动词需记忆） 动词用原形（第三人称单数加-s/es） 时间状语 yesterday, last week, in 2020, ago, when I was young 等 always, usually, often, every day, on weekends, now 等 动作性质 动作已结束，与现在无关 动作可能持续、重复或表示普遍真理 状态描述 过去的状态（常与be动词was/were连用） 现在的状态（常与be动词am/is/are连用） 二、具体用法对比 1. 动作的时间范围 一般过去时： 动作或状态发生在过去，且已经结束。 例： I watched a movie last night. （昨晚已看完电影） She was a teacher ten years ago. （过去的状态） 一般现在时： 动作或状态现在存在，或反复发生。 例： I watch movies every weekend. （习惯性动作） Water boils at 100°C. （客观真理） 2. 动词形式的变化 一般过去时： 动词必须变为过去式（规则或不规则）。 例： He played soccer yesterday. （规则动词：play → played） They went to the park last Sunday. （不规则动词：go → went） 一般现在时： 动词用原形，第三人称单数加-s/es。 例： She teaches English. （第三人称单数加-es） We study hard every day. （动词原形） 3. 时间状语的差异 一般过去时的典型时间状语： yesterday, last night/week/month/year, in 2010, two days ago, when I was a child 例： He bought a new bike last month. 一般现在时的典型时间状语： always, usually, often, sometimes, never, every day, on Mondays, now 例： I walk to school every morning. 4. 状态描述的区别 一般过去时描述过去的状态： 使用 was/were + 其他成分。 例： The weather was sunny yesterday. They were happy when they were young. 一般现在时描述现在的状态： 使用 am/is/are + 其他成分。 例： I am a student now. She is busy at the moment. 三、典型例句对比 一般过去时 一般现在时 I visited Beijing last summer. I visit my grandparents every year. He played the piano when he was 10. He plays the piano every day. They were students in 2015. They are teachers now. The train arrived late yesterday. The train arrives at 8 AM every day. 四、常见错误与纠正 1. 混淆时间状语： I go to the park last Sunday. → I went to the park last Sunday. She watches TV yesterday. → She watched TV yesterday. 2. 忘记动词变形： He play soccer last week. → He played soccer last week. They are happy yesterday. → They were happy yesterday. 3. 误用第三人称单数： She teach English. → She teaches English. He don’t like apples. → He doesn’t like apples. 五、总结口诀 一般过去时： “过去动作或状态，动词变形要记住；时间状语表过去，did/didn’t 助动词补。” 一般现在时： “现在习惯和真理，动词原形别忘记；三单加s或es，时间状语常伴随。” 单项选择(本大题共30小题，每小题2分，共60分) 1．—Listen!
