Unit3 Faster,Higher,Stronger语法讲解与练习 一、语法:动名词作主语详细讲解 1. 核心概念 动名词（v-ing）兼具动词和名词性质，在句中可以充当主语，表示经常性、习惯性、抽象性、泛指的动作。 v-ing作主语，本质是“把一件动作当作一件事”来看待，整体视作单数概念，谓语动词统一用单数形式。 2. 基础用法：v-ing直接置于句首作主语 结构：V-ing (+宾语/状语) + 单数谓语+其他 用法特点：描述笼统、习惯、客观事实，不特指某一次具体动作。 例句1：Doing exercise regularly is beneficial to our physical health. 译文：规律锻炼有益于我们的身体健康。 例句2：Keeping persistent helps athletes win more competitions. 译文：保持坚持不懈的状态有助于运动员赢得更多比赛。 3. 重点句型一：It 作形式主语 当v-ing主语过长时，为避免句子头重脚轻，常用it作形式主语，将真正的主语v-ing后置。 固定句型：It is + n./adj. + doing sth 常用形容词/名词：useful, useless, good, bad, worthwhile, a pity, no use, no good 例句1：It is no use regretting your mistakes after the competition. 译文：比赛后后悔自己的失误是没有用的。 例句2：It is worthwhile practicing basic skills every day for athletes. 译文：对运动员来说，每天练习基础技能是值得的。 4. 重点句型二：v-ing复合结构作主语 当需要明确动作的执行者时，用形容词性物主代词/名词所有格+ v-ing构成复合结构作主语，属于书面高级用法，考试常考。 结构：One’s doing sth +单数谓语 例句1：His sticking to training made him a top athlete. 译文：他坚持训练使他成为了一名顶尖运动员。 例句2：Her taking part in the game inspired all her teammates. 译文：她参加这场比赛鼓舞了所有队友。 5. 重难点辨析：v-ing作主语 vs to do作主语 二者均可作主语，但语义侧重不同： （1）v-ing 作主语 侧重：泛指、习惯、抽象、长期、反复性动作 例句：Playing sports builds up our body.（泛指运动这件事） （2）to do 作主语 侧重：特指某次、具体、一次性、未来的动作 例句：To take part in this match is his short-term goal.（特指本次比赛） 6. 核心易错点总结 1. 单独v-ing作主语，谓语动词一律用单数，切忌复数！ 2. No use / No good 后固定接doing，不接to do。 3. 句首作主语只能用物主代词+doing，不用宾格（him doing ❌ / his doing ✅）。 4. v-ing表“已知、习惯”；to do表“未知、具体计划”。 二、配套练习题 Ⅰ.用所给词的正确形式填空 1. ________ (take) exercise every day is a good habit for teenagers. 2. ________ (keep) a positive attitude is important for athletes. 3.
