     Every day life is made and lost. Every day, life goes on. Every day we experience some of the most

important parts of life and may not even realize it: love, generosity, and perseverance. These values aren't

just important to us; they make the world what it is.

     Scientists say that gravitational (重力的) force makes the world turn, but some people say that love

makes it go round. Love can be found anywhere: in families, friends, and even complete strangers. Even

if you can't see it, you know it's there.

     Love may connect people all over the world, but what would the world be without generosity? Whether

after a national disaster, or a school fund-raiser, one thing is certain-it is better to give than to receive.

Generosity is found everywhere and whether it's a large or small act, it makes a difference. Most of all,

being generous is not something you need any qualifications for, but no matter what you do, it can make

a difference. Sometimes, though, it takes effort to be generous, which leads us to perseverance.

     Founding a country, riding a bike, or finishing an essay, these are all finished with perseverance.

Perseverance is the one thing that can help us achieve whatever we want. It is what helps scientists to

discover cures for diseases, and athletes to become champions. You may fail, but every time you make

a mistake, that's one less to make the next time.

     There is an infinite (无穷的) number of things we value, but without love, generosity and perseverance,

we just don't think that our life or the world would be the way it is.
