介绍:
Some things need special care.
I can wash my hands and use things gently.
That way they won&`&t get dirty or broken.
I can use things a long time,and use only what I need.
Things last longer when I don&`&t waste.
I need to wait until I&`&m older to use some things.
I can use other things safely when I&`&m careful...
or when someone older helps me.
