该初中英语课件核心知识点为可数/不可数名词区分、冠词a/an正确使用、名词复数规则及不可数名词的量词搭配。课堂以“班级派对购物清单”为情境导入，先通过Brainstorm列出食物饮料，再用Box 1（apple, bread等）和Box 2（milk, carrot等）对比找不同，从类别和可数性两方面引出概念，逐步构建情境-概念-应用的学习支架。 其亮点在于情境化与任务驱动教学，以班级派对购物为真实任务，通过Box对比活动培养逻辑思维（思维品质），小组合作设计家庭派对清单提升合作学习能力（学习能力），融入健康生活意识（文化意识）。如食材清单练习“a packet of salt”等量词搭配，Group Work实践应用。学生能在真实情境中掌握语法，提升语言运用能力；教师可借助结构化活动高效教学。

Conclusion 1： We can use numbers or the article(a/an) with countable nouns. Part 1 If the countable noun begins with a consonant sound, we use “a”. 辅音音素开头用不定冠词a singular nouns (sing.) Rule 1 If the countable noun begins with a vowel sound, we use “an”. 元音音素开头用不定冠词an Tip: 一有元音音素现，an就闪亮来相伴 h是辅音字母，但在hour中不发音，发元音的是o， 用an “a” VS “an” an hour /aʊ/ a hat /h/ h是辅音字母，在hat中发辅音，用a Practice an umbrella /ʌ/ u是元音字母，在umbrella中发音是元音，用an a unit /juː/ u是元音字母，但在unit发音是辅音用a “a” VS “an” Practice 1. _____ book _____ egg _____ hamburger 2. _____ tomato _____ hour _____ carrot 3. _____ English teacher _____ American plane 4. _____ old bike _____ tall tree _____ orange 5. _____ umbrella _____ useful umbrella 6. _____ apple _____ big apple half _____ hour Practice: Fill in the blank with a/an. a an a a an a an an an a an an a an a an a lemon a pear a carrot a strawberry an apple an egg an orange an onion Part 2 To have a class party, we need more of them! three lemons five pears some carrots a lot of stawberries many apples lots of eggs a box of oranges four kilos of onions To have a class party, we need to buy: We add “s” to most nouns. If the noun ends with a consonant + y, we should change “y” into “ies”. Rule 1 plural nouns (pl.) Attention: “元音字母+y”结尾，直接加s变复数。 如：a toy-two toys And we still need to go to the Dayang Supermarket to buy 4 glasses of milk tea,3 boxes of peaches, tomatoes, potatoes to make special dishes with the help of knives. Watch and say:What will we need? We should add “es” after the nouns ending with “s”, “sh”, “ch” or “x”. We change “f”/“fe” into “ves” in the words ending with “f”/“fe”, such as “knife” “scarf” “leaf” “half” and “life”. We add “es” after the words ending with “o”, such as tomato, potato,hero. Rule 2 Attention: 其他以o结尾的无生命的单词常常直接+s构成复数。 如：a photo-two photos, a piano-two pianos. Are there any other special situations? Some special plural nouns Rule 3 不规则变化 man-men woman-women tooth-teeth foot-feet 改变单数名词中的元音字母 sheep-sheep deer-deer fish-fish Chinese-Chinese Japanese-Japanese 单复数形式相同 mouse-mice child-children 其他形式 1. match ________ 2. life ________ 3. month _______ 4. box _______ 5. library ________ 6. story _______ 7. radio _______ 8. foot _______ 9. woman _______ 10. sheep ______ Write the plural forms of the following words. matches lives months boxes libraries stories radios feet women sheep Practice Think:What foood do we have?
