Almost every machine with moving parts has wheels，yet no one knows exactly when the first wheel was invented or what it was used for.We do know，however，that they existed over 5,500 years ago in ancient Asia.

The oldest known transport wheel was discovered in 2002 in Slovenia.It is over 5,100 years old.Evidence suggests that wheels for transport didn’t become popular for a while，though.This could be because animals did a perfectly good job of carrying farming tools and humans around.

But it could also be because of a difficult situation.While wheels need to roll on smooth surfaces，roads with smooth surfaces weren’t going to be constructed until there was plenty of demand for them.Eventually，road surfaces did become smoother，but this difficult situation appeared again a few centuries later.There had been no important changes in wheel and vehicle design before the arrival of modern road design.

In the mid?1700s，a Frenchman came up with a new design of road—a base layer(層) of large stones covered with a thin layer of smaller stones.A Scotsman improved on this design in the 1820s and a strong，lasting road surface became a reality.At around the same time，metal hubs (the central part of a wheel)came into being，followed by the pneumatic tyre(充氣輪胎) in 1846.Alloy wheels were invented in 1967，sixty years after the appearance of tarmacked roads(柏油路)．As wheel design took off，vehicles got faster and faster.????????????? ????????????? ????????????? ????????????? ????????????? ????????????? ?????????????

科目：高中英語 來源：2010-2011學年湖北省高三上學期第二次聯考英語卷 題型：閱讀理解

One day, a young man was cleaning out his late grandfather’s belongings when he came across a bright red envelope. Written on the front were the words, "To my grandson." Recognizing his grandfather's handwriting ,the young man opened the enbelope. A letter inside read:

Dear Ronny, 

Years ago you came to me for help .You said, "Grandpa, how is it that you've accomplished so much in your life? You're still full of energy, and I'm already tired of struggling. How can I get that same enthusiasm that you've got?"

I didn't know what to say to you then. But knowing my days are numbered, I figure that I owe you an answer. So here is what I believe.

I think a lot of it has to do with how a person looks at things. I call it "keeping your eyes wide open."

First ,realize that life is filled with surprises, but many are good ones .If you don't keep watching for them, you'll miss half the excitement. Expect to be thrilled once in a while ,and you will be.

When you meet up with challenges, welcome them. They'll leave you wiser ,stronger, and more capable than you were the day before .when you make a mistake ,be grateful for the things it taught you .Resolve to use that lesson to help you reach your goals.

And always follow the rules. Even the little ones. When you follow the rules, life works. If you think you ever really get by with breaking the rules, you're only fooling yourself.

It's also important to decide exactly what you want. Then keep your ming focused on it, and be prepared to receive it.

But be ready to end up in some new places too ,As you grow with the years, you'll be given bigger shoes to fill. So be ready for endings as well as challenging beginnings.

Sometimes we have to be brave enough to move from the familiar to the unfamiliar .Life isn't just reaching peaks, Part of it is moving from one peak to the next .If you rest too long in between, you might be tempted to quit .Leave the past in the past .Climb the next mountain and enjoy the view.

Dump things that weigh you down emotionally and spiritually. When an old resentment, belief, or attitude becomes heavy ,lighten your load. Shed those hurtful attitudes that slow you down and drain your energy.

Remember that your choices will create your successes and your failures. So consider all the pathways ahead, and decide which ones to follow. Then believe in yourself, get up, and get going.

And be sure to take breaks once in a while .They'll give you a renewed commitment to your dreams and a cheerful, healthy perception of the things that matter the most to you .

Most important of all. never give up on yourself. The person that ends up a winner is the once who resolves to win. Give life everything you've got, and life will give its best back to you.

Love always,

Grandpa
