Unit3 The seasons语法讲解与练习 形容词(Adjectives)精讲 一、核心定义 形容词用来描述人或事物。形容词有两种基础摆放位置: 1. 放在名词前面(作定语) 2. 放在 be 动词(am / is / are)后面(作表语) 1. 形容词放名词前(定语,修饰名词) 结构:形容词+名词 课本例句:some cold drinks 冷饮 / some warm clothes 暖和的衣服 季节话题例句:a cool autumn 凉爽的秋天 / a hot summer 炎热的夏天 2. 形容词放在 be 动词后(表语) 结构:主语 + am/is/are +形容词 课本例句:It is hot today. 今天很热。 / It’s so windy. 风很大。 季节例句:Winter is cold. 冬天很冷。 / Spring is warm. 春天温暖。 二、必考重点句型:It is + 形容词 + to do sth. 1. 句型含义 表达对事情的感受、评价。中文:做某事是……的 2. 固定公式 It is + 形容词 + to + 动词原形 ️ to 后必须用动词原形,不能加 ing、不能变三单。 课本原句 1. It is exciting to visit new places. 参观新地方是令人兴奋的。 2. It is difficult to learn a new language. 学习一门新语言是困难的。 3. It is dangerous to feed wild animals. 投喂野生动物是危险的。 三、两种位置对比 位置 结构 例句 名词前(定语) 形容词 + 名词 cold wind 冷风 be动词后(表语) 主语 + be + 形容词 The wind is cold. 风很冷。 四、基础易错点 1. 形容词不能单独作谓语,必须搭配名词或be动词 Wind cold.    The wind is cold. / cold wind 2. It is...to do 句型中,to后一定是动词原形 It is fun to swimming.    It is fun to swim. 3. 形容词无单复数变化,永远不变形 五、极简背诵口诀 形容词,描人物,名前 be 后两位置; 名前直接放,be 后作表语; 评价事情有句型,It is + 形 + to do; to 后动词用原形,季节话题常运用。 六、单元话题背诵例句 1.
