Dear Peter:
How are you recently?I have a really happy life.Last week,my school held a scienve activity.The activity needs students invent something useful to help our daily life.Every of us joined positively.During the free time,they used knowledge they learned.By working hard,they invented many things.Such as telescope,microscope,luminous slippers and glass cleaner and so on.Some experts thought highly of the inventions.
By this activity,I learned many things.I knew that studying is a long period,we shouldn't give up learning or being proud of ourselves.Studying has no end.
Yours,
