小学英语语法 —— 一篇分清代词 it /one/that用法!

孩子做选择题总在 it / one / that 上栽跟头——"前面刚说了一本书,后面到底用哪个?"
其实这三个词就差在"是不是同一个东西"。下面一张表先秒懂,再逐个拆解,配合口诀,看完就能用。

📊 一张表秒懂
| it | |||
| one | |||
| that |
① it —— 就是"它",同一个
用法:代替前文提到过的同一个东西。复数用 they / them。
• I bought a book. It is interesting.(我买了本书,它很有趣。→ 就是那本)• Look at the dog. It is running.(看那只狗,它在跑。→ 同一只)
🌟 小贴士:it 还能指时间、天气、距离——It is rainy. It is 8 o'clock.
② one —— 同类另一个,泛指
用法:代替前文同类事物中的一个,但不是同一个;表泛指,复数用 ones。
• My ruler is short. I want a long one.(我的尺子短,想要把长的。→ 另一把)• This cake is small. Give me a big one.(这块蛋糕小,给我块大的。→ 另一块)
🌟 小贴士:复数用 ones——I like red apples. I want those ones.

③ that —— 比较里的"那个"
用法:代替前文同类事物,常用于比较句;多代单数可数或不可数名词,复数用 those。
• The weather in Harbin is colder than that in Guangzhou.(哈尔滨天气比广州冷。→ that = the weather)• His score is higher than that of Lily.(他分数比莉莉的高。→ that = the score)
🌟 小贴士:that 一般指"另一个/远处的",不像 it 指"同一个"。
👀 同一场景,三种用法对比
桌上放着两本书:
• This book is mine. It is new.(it = 这本,同一本)• This book is old. I want a new one.(one = 另一本新的,同类)• The cover of this book is nicer than that of yours.(that = the cover,比较用)
看懂这一组,三个词就彻底分清楚了。
🔖 记忆口诀
it 同一,one 泛指,that 比较来替他。
语法规则看懂了,但真要变成孩子自己的语感,多读多说最管用。
