[单项选择]You might guess that experienced drivers have fewer accidents, but research from insurer AXA has revealed that they are more law-abiding and honest, too. A poll of 2 000 drivers in the UK found that those who have been behind the wheel for eight years or more had not only caused half as many accidents in the last year as less experienced drivers, but were also less likely to have broken the law or lied to their insurer.
Experienced drivers were half as likely to have been caught using a mobile phone while driving within the last year; and a third as likely to have been caught driving under the influence of alcohol or drugs, or to have been convicted of dangerous driving. They were also a fifth as likely to have been convicted of driving without a seatbelt.

Most of what I really need to know about how to live and what to do and how to be,I learned in kindergarten.Wisdom was not at the top of the graduate mountain,but there in the sand pile at nursery school.
These are the things I learned:Share everything. Play fair. Don't hit people.Put things back where you found them.Clean up your own mess.Don't take things that aren't yours.Say you're sorry when you hurt somebody.Wash your hands before you eat.Warm cookies and cold milk are good for you.Live a balanced life.Learn some and think some and draw and paint and sing and dance and play and work everyday some.
Take a nap every afternoon.When you go out into the world,watch for traffic,hold hands and stick together. Be aware of wonder. Remember the little seed in the plastic cup?The roots go down and the plant goes up and nobody really knows how or why,but we are all like that.
Goldfish and hamsters and white mice and even the little seed in the plastic cup一they all die.So do we.
And then remember the book about Dick and Jane and the first word you learned,the biggest word of all: Look.Everything you need to know is in there somewhere,the Golden Rule and love and basic sanitation,ecology and polities and sane living.
Think of what a better world it would be if we all一the whole world一had cookies and milk about 3 o'clock every afternoon and then lay down with our blankets for a nap.Or if we had a basic policy in our nations to always put things back where we found them and cleaned up our own messes.And it is still true,no matter how old you are,when you go out into the world,it is better to hold hands and stick together.
And it is still true,no matter how old you are,when you go oul into the world,it is better to hold hands and stick together.
