三、核心句型(构成+用法+例句)
(一)水果喜好问答(一般现在时一般疑问句)
句型1:Do you like + 水果复数?
构成:助动词Do + 主语you + 动词原形like + 可数名词复数
用法:询问对方是否喜欢某类水果(水果一类要用复数)
肯定回答:Yes, I do.
否定回答:No, I don’t.
例句:
—Do you like apples? 你喜欢苹果吗?
—Yes, I do. 是的,我喜欢。
—Do you like bananas?
—No, I don’t. I like grapes.
句型2:And you? 你呢?

例句:
—I like oranges. And you?
—I like apples.
(二)如何帮助植物(提建议,情态动词can)
句型:We can + 动词短语.
构成:主语We + 情态动词can + 动词原形
用法:can表示“可以、能够”,用来说出帮助植物的方法,can后永远用动词原形
例句:
We can water the flowers. 我们可以浇花。
We can plant new trees. 我们可以种树。
提问句型:How can we help plants?
翻译:我们可以怎样帮助植物?
回答:We can…
(三)植物生长需求

Oo 短元音 /ɒ/:orange, fox 嘴巴张大短音
Pp 发音 /p/:pen, cup 清辅音,轻读不爆破

五、核心语法
1. 情态动词 can
含义:能够、可以,表能力/建议
固定规则:can后面必须加动词原形
✅ We can plant trees.
❌ We can plants trees.
句式变换
陈述句:主语 + can + 动词原形
特殊疑问句:What/How can + 主语 + 动词原形?
How can we help plants?
2. 一般现在时一般疑问句 Do you like…?
适用:询问长期喜好
规则:
① 主语you,助动词用Do放句首
② like后水果用复数(表一类事物)
③ 答句用助动词do/don’t,不能用like
✅ —Do you like oranges? —Yes, I do.
❌ —Yes, I like.
3. 名词单复数
水果、植物可数名词:表一类事物,必须用复数
apple→apples, tree→trees, flower→flowers, grape→grapes
不可数名词(无复数,不加s):water, air, grass, sun
六、重难点
1.can + 动词原形 是本单元最重要考点,所有can后面动词不能加s/ing
2.like后水果用复数,泛指这一类水果
3.need含义:人/植物“需要”某物,主语复数时need不变形(plants need)
4.water一词多义:n.水(不可数);v.浇水(water the flowers)
5.问答对应:Do you like…? 回答只能用Yes, I do./No, I don’t.
七、易错点汇总
1.错误:We can waters the flowers.
正确:We can water the flowers.(can后原形)
2.错误:Do you like apple?
正确:Do you like apples?(一类用复数)
3.错误:—Do you like grapes? —Yes, I like.
正确:Yes, I do.(问答助动词匹配)
4.错误:Plant need sun.
正确:Plants need sun.(表一类植物用复数)
5.混淆:air/water/sun无复数,不能加s
6.字母Oo混淆:短音/ɒ/,不要读成长音
