【知识点拨】：
1. I’ve just eaten it.
用法：1. just 做副词，意为“刚刚，刚才”通常与现在完成时连用。
举例：Mr Wang has just left our class. I have just heard the n
ews.
拓展：just now “刚刚，刚才”常与一般过去时连用，多用于句末。
e.g I met a friend in the street just now.[来源:Zxxk.Com]
just then “就在那时”
e.g. Just then, someone knocked on the front door.
2. You’ve changed a lot.
用法：1. change 句中“changed”是 “change”的过去分词。此处change为不及物动词，意为变化，改变。
举例：The city has changed a lot since 2000.
拓展：1. change 做及物动词 意为“交换，改变，换乘”
e.g. Can I change the seat with you? I stayed in Moscow to change the plane.
2. change 做可数或不可数名词，意为“改变，变化，转变”；用作不可数名词意为“零钱”
e.g. Great changes have taken place in my hometown since 1978.
Here is your book and your change.
3. You used to share food with me.
用法：1. used to 意为“过去常常，曾经”后接动词原形
举例: My sister used to be very shy.
I used to read English in the evening, but now I usually read it in the morning.
拓展：该短语的否定形式有两种，分别为：didn't use to do, used not to do
e.g． My cousin didn’t use to have short hair.= My cousin used not to have short hair. 我表姐以前不留短发。
该短语在变为一般疑问句时同样有两种形式：一是将used 提前，即 Used +主语+to do sth. ? 二是主语前加did, 并将used 改为动词原形 use ，即Did+主语+ use to do sth.
?
e.g. Did you use to go to the movies?= Used you to go to the movies?
2. （旧知回顾）share sth with sb.
举例： She shares lunch with her friends.
4. You used to be so kind to me.
用法：1. so 副词，意为“如此”修饰形容词和副词
举例： The boy is so strong that he can lift the heavy box.
My father walks so quickly.
2. be kind to… 对…友好
举例: We should be kind to others.
