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 gravitaional(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, 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. 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. 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. 1.
