Unit 1 Feeling good 语法讲解与练习 语法:过去完成时详细讲解 一、核心定义 过去完成时表示:在过去某个动作,某个时间点之前已经发生,已经完成的动作,即“过去的过去”。 基本结构:had +过去分词(done) 无人称和数的变化,所有人称统一用had 二、核心知识点精讲 知识点1:基本用法——过去两个动作,先发生的用过去完成时,后发生的用一般过去时 逻辑:先后顺序清晰,“先完后发” 例句1:I had felt anxious for weeks before I adjusted my lifestyle. 例句2:She had developed a positive mood before she learned to relieve stress. 知识点2:过去完成时 + 时间状语(by/ before/ until + 过去时间点) 标志词:by the time…, before…, until then, by 2020(过去年份) 例句1:By the time he graduated, he had formed healthy living habits. 例句2:Before the doctor gave advice, I had suffered from bad moods for long. 知识点3:表示过去持续的状态(延续用法) 搭配:for + 一段时间 / since + 过去时间点,强调“过去某时之前一直持续” 例句1:He had lacked enough nutrition for months before he changed his diet. 例句2:People had ignored mental health since childhood until experts reminded them. 知识点4:用于宾语从句(主句过去时,从句动作更早发生) 口诀:主句过去,从句“过去的过去”必用过去完成时 例句1:Scientists found that stress had affected people’s mood greatly. 例句2:She said she had appreciated the power of positive thinking. 知识点5:虚拟语气用法(与过去事实相反) 结构:If + 主语 + had done,主语 + would/could have done 例句1:If he had kept a regular schedule, he would not have felt depressed. 例句2:If we had valued mental health earlier, we could have avoided anxiety. 知识点6:固定句型:Hardly/Scarcely…when… / No sooner…than…(一……就……) 倒装结构:助动词had提前 例句1:Hardly had she adjusted her mood when new pressure came. 例句2:No sooner had they adopted new habits than their health improved. 三、重难点辨析 1. 一般过去时 VS 过去完成时 一般过去时:单纯陈述过去发生的事(无先后对比) 过去完成时:强调过去的过去、动作先后、时间截止 例句对比: ① He studied mental health.(单纯过去动作) ② He had studied mental health before he became optimistic.(先学后乐观) 2. 瞬间动词可用于过去完成时,不与延续时间连用 正确:He had abandoned his bad habits.(瞬间动作) 错误:He had abandoned his bad habits for two years. 【配套专项练习】 大题一:单词正确形式填空 1.
