Unit3 Fascinating Parks语法讲解与练习 一、核心语法精讲：动名词（doing）作主语 1. 基本概念 动名词（v-ing）兼具动词和名词性质，在句中可以充当主语，表示习惯性、经常性、一般性的动作或抽象行为。 核心特征：doing作主语，谓语动词一律用单数形式。 2. 基础句式结构（必考） 结构1：单个动名词/动名词短语作主语 公式：Doing sth. +单数谓 +其他 单元话题例句：Wandering in the vast valley is extremely relaxing. 逐句解析： ① Wandering（漫游、漫步）为动名词，在句中作主语； ② 主语是抽象行为，视作单数，谓语动词用is； ③ 句意：在辽阔的山谷中漫步十分令人放松。 结构2：It 作形式主语 当动名词短语过长时，为避免句子头重脚轻，用 It 作形式主语，真正主语后置。 固定句型：It is + adj./n. + doing sth. 单元例句：It is rewarding exploring the wild national parks. 解析：It为形式主语，真正主语是exploring the wild national parks（探索野生国家公园），句式简洁，写作高频好用。 3. 三大核心用法 用法一：表示习惯性、一般性的行为（最常用） 动名词作主语，不特指某一次动作，侧重长期、常态、普遍行为。 例句：Observing wild animals in the reserve requires patience. 解析：在保护区观察野生动物（常态行为）需要耐心，而非单次动作，用observing作主语，谓语requires用单数。 用法二：表示抽象行为、活动意义 用于评价某类行为的价值、作用、特点，贴合单元写景、抒情、评价游玩体验的语境。 例句：Admiring the splendid glacier scenery brings people peace. 解析：欣赏壮丽的冰川景色（抽象行为）能带给人们平静，动名词短语作主语，谓语单数brings。 用法三：并列动名词作主语（特殊考点） 两个及以上动名词并列，表同一整体、同一类行为时，谓语用单数；表两个独立动作时，谓语用复数。 例句（整体）：Hiking and camping is a popular outdoor activity in mountain parks. 解析：徒步露营是一套整体户外活动，视作单数，谓语用is。 例句（独立）：Climbing mountains and watching waterfalls offer us different joys. 解析：爬山和看瀑布是两个独立行为，谓语用复数offer。 4. 重点辨析：doing作主语 VS to do作主语 Doing 作主语：常态、习惯、抽象行为、客观事实（本单元绝大多数场景） To do 作主语：具体某一次动作、未来特定目的、临时行为 对比例句： Walking in the forest is enjoyable.（常态：在林间散步很惬意） To walk in the forest this afternoon is my plan.（单次：今天下午去林间散步是我的计划） 5. 必考易错点 ❌ 易错1：动名词作主语，谓语动词误用复数 错：Exploring parks bring us happiness. 对：Exploring parks brings us happiness.（单数谓语） ❌ 易错2：混淆动名词与现在分词 现在分词doing作定语/状语；动名词doing作主语/宾语，功能完全不同。 ❌ 易错3：形式主语句型误用to do 固定评价句型（It is useless/worthwhile/rewarding）后优先用doing 6. 单元重点搭配积累 wandering in the valley 在山谷漫步 exploring polar regions 探索极地 admiring splendid scenery 欣赏壮丽景色 watching wild animals 观赏野生动物 hiking along the route 沿路线徒步 二、专项配套练习 大题一：用所给动词的适当形式填空 1. ________ (wander) around the national park is a wonderful experience. 2. ________ (admire) the vast glacier brings visitors great shock. 3. ________ (explore) remote valleys requires enough courage and preparation. 4. ________ (watch) reindeer walking in the snow is very interesting. 5. ________ (hike) along the mountain route makes people relaxed. 6. ________ (observe) wild animals needs great patience. 7. ________ (discover) unknown views in the park is rewarding. 8. ________ (respect) nature is everyone’s duty. 9. ________ (protect) rare animals matters a lot. 10. ________ (follow) the official route prevents visitors from getting lost. 大题二：句子改写（改为动名词作主语句式） 要求：将原句改写为 v-ing作主语 的句式，句意不变 1.
