Unit7-8 语法（讲义）-2024-2025学年译林版（三起）（2024）英语三年级下册

译林版-三下（新版）Unit7-8-语法讲练测 【核心语法】 一、指示代词 these/those 的用法 知识点： • these（这些）：指代距离说话人较近的复数事物。 • those（那些）：指代距离说话人较远的复数事物。 • 句型结构： 1）What are these/those? → They’re + 名词复数（例：They’re cows.） 2）Are these/those...? → Yes, they are./No, they aren’t. 易错点： 1）混淆 these 和 those 的远近关系（错误：What are these? 指向远处物品）。 2）答语中漏用复数代词 they（错误：Are these pigs? → Yes, these are. → 正确：Yes, they are.）。 练习题： 1. —What are ______ (these/that)? —They’re ducks. 2. 改错：What are those? It’s apples. → _________________ 3. 翻译：那些是奶牛吗？→ _______________________ 4. 连词成句：are / what / those / under / tree / the / ? _______________________ 5. 选择：—Are ______ chickens? —No, they’re ducks. A. these B. this C. that 6. 填空：—What ______ (be) these? —They’re pigs. 7. 改错：Are those a sheep? → _____________________ 8. 翻译：这些是橙子吗？→ ______________________________ 9. 判断：These 和 those 后接动词单数形式。（ ） 10. 选择：—What are ______? —They’re eggs. A. this B. that C. those 二、名词复数与不规则变化 知识点： • 规则复数：加 -s（apples, ducks），以 -o 结尾加 -es（tomatoes）。 • 不规则复数：sheep → sheep, fish → fish, child → children。 易错点： 1）误加复数后缀（错误：sheeps → 正确：sheep）。 2）混淆可数名词与不可数名词（错误：two milks → 正确：two glasses of milk）。 练习题： 1. 写出复数：sheep → ______，child → ______，tomato → ______。 2. 选择：I see three ______ (fish/fishes) in the pond. 3. 改错：There are many sheeps on the farm. → ___________________________ 4. 翻译：那些是母鸡吗？→ __________________________ 5. 填空：How many ______ (duck) are there? 6. 连词成句：are / there / five / cows / farm / the / on / . _______________________________________ 7. 判断：Fish 的复数形式只能是 fish。（ ） 8. 选择：These ______ (is/are) my new books. 9. 翻译：树上有三只鸟。→ _____________________________ 10. 填空：The ______ (child) are playing games. 三、颜色形容词与疑问句 What colour...? 知识点： • 颜色形容词直接修饰名词（例：a red apple）。 • 句型：What colour is/are...? → 回答单数用 It’s...，复数用 They’re...。 易错点： 1）颜色形容词后加名词时漏用冠词（错误：This is red apple. → 正确：This is a red apple.）。 2）混淆 What colour 和 How colour（错误：How colour is the sky?）。 练习题： 1. —______ is the flower? —It’s pink. 2. 改错：What colour are the apple? → __________________________ 3. 翻译：你的书包是什么颜色？→ _______________________ 4. 连词成句：colour / is / what / dress / your / ? _____________________________________ 5. 填空：The balloons ______ (be) blue and yellow. 6. 选择：—What colour ______ the leaves? —They’re green. A. is B. are C. am 7. 改错：This is orange shirt. → _______________________ 8. 翻译：那些鸟是黑色的。→ ____________________________ 9. 判断：What colour 后接单数名词时用 is。（ ） 10. 选择：—What colour is ______? —It’s white. A. these B. the cat C. those 四、介绍人物与物品的句型 知识点： • This is... / That is... 用于介绍单数人或物。 • These are... / Those are... 用于介绍复数人或物。 易错点： 1）混淆 this 和 these 的单复数（错误：This are my friends.）。 2）漏用 be 动词（错误：These my pencils. → 正确：These are my pencils.）。 练习题： 1. 改错：That are my brother. → ________________________ 2. 翻译：这是我的新老师。→ __________________________ 3. 填空：______ (This/These) are red apples. 4. 连词成句：is / that / umbrella / your / ? ____________________________________________ 5. 选择：—______ is my cousin. —Nice to meet you.
