Unit 7 Days and months 语法 课件2026--2027学年冀教版英语七年级上册

该初中英语课件聚焦基数词与序数词的构成、功能及用法，通过“一年有多少个月”引出基数词，再以“十二月是第十二个月”过渡到序数词，构建从数量到顺序的认知支架，帮助学生建立知识联系。 其亮点在于用“基数变序有规律”等chant口诀强化记忆策略，结合月份-数词对应表和日期填空任务提升语言运用能力，分层作业（必做转换造句、选做编对话）促进思维发展，既助学生系统掌握数词用法，也为教师提供清晰教学路径。

Unit 7 语法 Days and months 1 Learning objectives In this lesson, we will be able to: 1.Understand that numerals have two types: cardinal (showing quantity, like “one, two”) and ordinal (showing order, like “first, second”), and know their basic roles. 2.Identify how cardinal numerals form (special forms for 1 - 12, 13 - 19, 20 - 100) and how some basic cardinal numerals change to ordinal ones (e.g., one→first). 3.Recognize usage situations: use cardinal for quantity, time, age, etc., and ordinal for order, date, etc., from sentences and tables. 4.Apply cardinal and ordinal numerals correctly in tasks like filling tables and completing passages to describe quantity, order, time, dates. 2 There are ________ months in a year. Lead in twelve How many months are there in a year? December is the ________ month of a year. Lead in twelfth 数词是表示数目多少和顺序先后的词，分为基数词（cardinal numeral）和序数词（ordinal numeral）。基数词表示__________，序数词表示__________。 数目 顺序 twelve twelfth 数词 Numeral Perceive the difference A cardinal number says the quantity of something. An ordinal number tells us the order of something in a list. Usually, when we change a cardinal to an ordinal, we can simply add -th. But sometimes -th doesn’t work. For example, one — first, two — second, three — third. 基数词 序数词 6 Cardinal numers 基数词的构成 （1）1 - 12 为：one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve （2）13 - 19 为：thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen （3）20 - 100 为：twenty, twenty-one, twenty-two, twenty-three... thirty...forty...fifty...sixty...seventy...eighty... ninety...one hundred 注意： 基数词 13 - 19 的构成一般为个位基数词后面直接加 -teen，但 13 和 15 的拼写发生变化，18 省去 eight 中的字母 t 再加 -teen。 2.基数词的用法 Ten of them are boys.
