Unit5 The power of plants语法(现在进行时)讲解与练习 一、现在进行时 超详语法精讲 （一）核心定义与两大必考用法 现在进行时是七年级核心重难点时态，主要描述当下正在发生的动作或现阶段持续进行的暂时性动作，贴合本单元植物观察、自然场景、日常正在进行的活动语境。 用法1：此时此刻正在进行的动作（即时动作） 搭配标志性提示词：now, right now, Look!, Listen!, Be quiet! 例句1：Look! The plants are growing fast in the sun. 看！这些植物正在阳光下快速生长。 例句2：Listen! The birds are singing in the trees. 听！鸟儿正在树上歌唱。 用法2：现阶段正在进行、此刻未必正在做的暂时性动作（拔高考点） 搭配提示词：these days, at present, recently，强调一段时期内的持续状态 例句：We are learning about plant power these days. 我们这些天正在学习植物的力量相关知识。 （二）完整句式结构（肯/否/疑/简答全覆盖） 核心公式：主语 + be动词(am/is/are) + 动词现在分词(doing) +其他 be动词随主语变化：I用am，单数主语/不可数名词用is，复数主语用are 1. 肯定句 结构：主语 + am/is/are + doing 例句：She is watering the flowers in the garden. 她正在花园里浇花。 2. 否定句（高频考点） 结构：主语 + am/is/are + not + doing 例句：They are not studying plant knowledge now. 他们现在没有学习植物知识。 3. 一般疑问句 结构：Am/Is/Are + 主语 + doing + 其他？ 例句：Is the grass growing well in spring? 小草正在春天茁壮成长吗？ 4. 简短回答（问答一致原则） 肯定：Yes, 主语+be. 否定：No, 主语+be not. —Are you watching the plant growth? 你正在观察植物生长吗？ —Yes, I am. / No, I’m not. （三）动词现在分词(doing) 完整变形规则（必考） 1. 一般动词：直接加 ing 例：look-looking, grow-growing, play-playing, read-reading 2. 以不发音字母e结尾：去e加ing 例：make-making, take-taking, write-writing, 3. 重读闭音节（辅+元+辅）结尾：双写末尾辅音字母再加 ing（重难易错点） 例：run-running, stop-stopping, sit-sitting, swim-swimming 4. 特殊变形：ie结尾变y加 ing 例：lie-lying, tie-tying （四）终极易错重难点 1. 状态动词不用于进行时：表示感官、拥有、喜好、状态的动词无进行时，只用一般现在时 常见词：see, hear, like, love, have(拥有), know, want, need, believe 错例：I am liking plants. (✘) 正例：I like plants. (✔) 2. 瞬间提示词必判时态：Look/Listen开头的句子，**百分百用现在进行时** 3. 现阶段动作区分：these days 不用一般现在时,侧重近期持续状态,用现在进行时 4. be动词缺一不可：进行时必须同时有be+doing,单独doing不能作谓语 【巩固练习】 大题一：用所给词的正确形式填空 1. Look!
