there are two ways of going knowledge. They are knowledge gained from experience and books. Knowledge from experience makes understanding easy. And knowledge from books helps describe details. While knowledge gained from experience and books is very difficult , I think knowledge from experienced is is more important.First, knowledge from experience can make understanding easy and remember for a long time. For example, in a natural science class, if a teacher only explains science , we won't understand this science principle, so we can't understand easily, But if we do experimentation, we understand easily.Second, knowledge from experience can make people remember for a long time.For example, if people become acquainted knowledge times. But people take a direct experience, they remember for a long time. So I think becoming acquainted is not as important as remembering. In conclusion, I think knowledge from experience is more important than books.Therefore, I think knowledge from experience is more important than knowledge from books. The reasons are first, about understanding and second, about remembering. I hope that many people heard about knowledge gained from experience.

food has become easier,,

Nowadays, food has become easier to prepare.
I think it can be bad and also good.
Now, many things have develop.
And then, even food is improve.
I think it has improved the way people live.
First, many people annoyed to make food,
Specially, many housewife are.
But if food is improved, many housewives are good for their life,
and less annoyed.
Second, people can eat a variety of food.
If food is not improves, they always eat same thing.
But in the other side, if food is improved,
people eat abundant food. Each people.
Therefore, my opinion is of course this change is improved the way people live.
I hope that many people contact a variety of food.
And people feel good.^^
