Unit 2 Animals（期中知识清单）英语新交际英语版一年级下册（新教材）

知识清单·新交际英语二年级下册 Unit2 Animals 知识梳理 知识点拨 【考点一】单数/复数指示句型（It's... / They're...） 【考点二】be动词（is/are）的用法区分 【考点三】特殊疑问句What are they? 的问答 【考点四】可数名词单复数变化规则 考点一：单数/复数指示句型（It's... / They're...） —What is it? —It's a panda. —What are they? —They're monkeys. 解析 本单元核心句型用于介绍动物的单复数，是小学英语入门阶段的重点： 1. 单数句型：It's + a/an + 单数名词 It's = It is，意为“它是”，用于指代单个人/物/动物； 单数名词前必须加不定冠词 a（辅音音素开头，如 a tiger）或 an（元音音素开头，如 an elephant）； 例句：It's a bear.（它是一只熊） 2. 复数句型：They're + 复数名词 They're = They are，意为“它们是”，用于指代多个人/物/动物； 复数名词直接用，不加 a/an，需注意名词的复数变化（如 monkey → monkeys，lion → lions）； 例句：They're bears.（它们是熊） 易错点 单复数混淆：单数用 It's，复数用 They're，不可混用（❌ It's monkeys. ✅ They're monkeys.） 漏加冠词：单数名词前必须加 a/an（❌ It's tiger. ✅ It's a tiger.） 【大显身手】 一、单项选择 ( ) 1. —What is it? —______ a bear. A. It's B. They're C. I'm ( ) 2. —What are they? —______ monkeys. A. It's B. They're C. He's ( ) 3. ______ a cute panda. A. It's B. They're C. You're ( ) 4. Look at ______ lions. ______ big. A. the; It's B. a; They're C. the; They're ( ) 5. —______? —They're tigers. A. What is it B. What are they C. How are you 二、用It's或They're填空 1. ______ a zoo. 2. ______ cute bears. 3. ______ a big tiger. 4. ______ two lions. 5. ______ a lovely panda. 考点二：宠物所属关系的表达（It's my... / It's my friend's... 句型） is 用于单数主语（it, he, she, 单个名词） are 用于复数主语（they, we, you, 多个名词） 解析 1. 主语为单数：It is (It's) a lion. / The tiger is big. 2. 主语为复数：They are (They're) monkeys. / The bears are big. 3. 特殊情况：you 无论单复数，都用 are（You are a student. / You are students.） 易错点 主谓不一致：复数主语用 is（❌ They is bears. ✅ They are bears.） 缩写错误：It's ≠ Its（Its 是形容词性物主代词，意为“它的”，如 Its tail is long.） 【大显身手】 一、用is或are填空 1. This ______ a tiger. 2. These ______ monkeys. 3. It ______ a big bear. 4. They ______ cute pandas. 5. The lion ______ strong. 二、单项选择 ( ) 1. I ______ a student. You ______ my friend. A. am; is B. am; are C. is; are ( ) 2. The bears ______ big. A. is B. are C. am ( ) 3. —What ______ it? —It ______ a panda. A. is; is B. are; are C. is; are ( ) 4. They ______ my favourite animals. A. is B. are C. am ( ) 5. Look! The monkey ______ cute. A. is B. are C. am 考点三：特殊疑问句What are they? 的问答 —What are they? —They're pandas. 解析 1. 问句：What are they? What 疑问词，意为“什么”，用于询问事物的名称； are 因为主语 they 是复数，所以用 are； they 指代多个事物，对应答句的复数名词。 2. 答句：They're + 复数名词 必须用复数名词回应，不可用单数（❌ They're a panda. ✅ They're pandas.） 拓展 单数对应问句：What is it? 答句：It's a/an + 单数名词 例句：—What is it? —It's a monkey. 【大显身手】 一、按要求改写句子 1. It's a tiger.（改为复数句） ______ ______ ______. 2. They're bears.（改为单数句） ______ ______ ______. 3. They are monkeys.（改为一般疑问句，并作肯定回答） —______ ______ monkeys? —______, ______ ______. 4.
