Unit1 Look it up!讲解与练习 some /any +复合不定代词详细讲解 第一部分 some & any 1.作限定词（后接名词，修饰复数可数名词、不可数名词） some ①多用于肯定句，表示 “一些” I have some books. ②疑问句特例：委婉请求、邀请，期待对方肯定回答,不用 any,用 some Would you like some coffee? Could I have some water? any ①多用于否定句、普通疑问句，表示 “一些” I don’t have any pens. Do you have any questions? ②拓展：any 用于肯定句，意思变为任何 You can ask any student.（你可以问任意一名学生） 2. some /any 作不定代词（后面不加名词，单独使用，指代上文提到的人/事物） — Do you have stamps? — I have some.（some = some stamps） I need paints. Do you have any?（any = any paints） 第二部分 复合不定代词 一、词汇分类 1. 指代人（-body /-one 两组词义完全相等，可以互换） somebody = someone 某人 anybody = anyone 任何人 nobody = no one 没有人 2. 指代事物（-thing 结尾） something 某物，某事 anything 任何事物 nothing 没有东西，没有事 补充：everyone /everybody 每个人；everything 一切 二、使用规则 1：句式选用规律（和 some/any 逻辑一致） ✅ 肯定句→ some 类不定代词：someone /somebody/something ✅ 否定句、疑问句→ any 类不定代词：anyone /anybody/anything ✅ nobody /nothing 本身自带否定含义，只用在肯定句式中表达否定意思 1.肯定句 There is someone at the door. I have something to tell you.Nobody knows his secret.（nobody 本身表否定，句子不用 not） 2.否定句（句中有 not） I don’t know anyone here. He didn’t say anything. 3.一般疑问句 Is there anybody in the classroom? Did you buy anything? ⚠重要转换公式（同义句必考） nothing = not anything nobody = not anybody / no one I found nothing. = I didn’t find anything. Nobody came. = No one came. 三、使用规则2：主谓一致 所有复合不定代词作主语，一律视为单数，谓语动词用单数形式 Someone is calling you. ✔ Nobody likes boring films. ✔ Something is wrong. ✔ ❌ 错误示范：Someone are waiting. 四、使用规则 3：定语后置（重中之重，单选必考） 形容词、不定式 (to do) 修饰复合不定代词时，必须放在不定代词后面 结构：不定代词 + 形容词 /to do something interesting 有趣的事 ✔ interesting something ❌ anything new 任何新鲜事物 ✔ nothing important 没有重要的事 I have something to tell you.（to do 后置作定语） 五、使用规则 4：反义疑问句难点 1.主语 someone /anyone/everyone /somebody anybody everybody,反义疑问句主语通 用they Everyone is here, aren’t they? Someone is knocking, aren’t they? 2.主语 nothing /something（事物）反义疑问主语用it Something is wrong, isn’t it? 3.主语 nobody /no one（表否定含义）句子本身为否定句，疑问部分用肯定 Nobody knows the truth, do they? 六、词义辨析易混点 1.someone vs anyone someone：某人（肯定句，特指有一个人，但不说名字） anyone：任何人（否定 / 疑问；肯定句中表 “任意一个人”） Anyone can join this club.（任何人都能加入） 2.something vs anything something 某事/某物（肯定句） anything 任何事物，用于否定句 = 任何东西 Is there something wrong?（极少情况，期待肯定回答，口语可用） 3.nobody vs everyone nobody 没有人；everyone 每个人 【配套练习】 一、用所给单词的正确形式填空 根据句意、句式结构，填入some/any及复合不定代词的正确形式。 1.
