Wheels are everywhere around you and me, 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 (层)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 tire (充气轮胎) 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 go faster and faster.
1.What might be the reason why transport wheels wasn’t that popular for some time?
A. Few knew how to use transport wheels.
B. Humans carried farming tools just as well.
C. Such animals as horses and bulls were still a good means of transport.
D. The existence of transport wheels was not known.
2.How is the last paragraph mainly developed?
A. By giving examples.
B. By following time order
C. By making comparisons.
D. By making classifications.
3.What is the passage mainly about?
A. The beginning of road design.
B. The history of public transport.
C. The developmentt of transport wheels.
D. The invention of fast-moving vehicles.

Free energy is everywhere around us. There are many ways to make and collect energy from various sources like sun, wind and water. People also realize that everyday stuff can be a source of energy too. For example, riding a bike, running or just walking, etc. We simply have to change our way of thinking if we want to change the world.
So comes the idea of solar roadways. Are they the road of future? Why use roads just for driving and collecting tolls (过路费)? Why don’t we use them for collecting energy?
The US Department of Transportation recently awarded $100,000 to Solar Roadways to build the first ever Solar Road Panel. So how do these future roads work?
The Solar Road Panels will contain embedded (嵌入的) LEDs which “paint” the road lines from beneath to provide safer nighttime driving as well as to give drivers instant instructions such as detour (绕行) ahead. The road will be able to sense wildlife on the road and can warn drivers to “slow down”. There will also be embedded heating elements in the surface to prevent snow and ice buildup, providing safer winter driving.
Replacing asphalt (沥青) roads and parking lots with Solar Roadway Panels will be a major step toward stopping climate change. Fully electric vehicles will be able to recharge along the roadway and in parking lots, finally making electric cars practical for long trips.
We just can’t wait to see more of these roads all over the world in the near future.
1.The first paragraph serves as a(n)______.
A. argument B. comment C. explanation D. background
2.Which of the following is NOT true of LEDs?
A. They color the road lines.
B. They are embedded in the Solar Road Panels.
C. They are beneficial for nighttime driving.
D. They can provide instant instructions.
3. When some animals are on the solar road, what will the road do?
A. Guide them to a safer place. B. Remind drivers to drive slowly.
C. Frighten them away from the road. D. Advise drivers to choose another way.
4. From the text, we can know that the Solar Road Panels can______.
A. provide heat for drivers in winter
B. guide drivers who get lost on the highway
C. melt snow and ice soon in winter
D. help drivers see the road clearly in the sun

If you have no friends around you, it’s time that you should know about your neighborhood. Not all of your neighbors out there are friendly, but at least you need to communicate with them. It is common that when you are new to the neighborhood, your neighbors might actually greet you in an inspiring way.
In other words, they are pleased to welcome you in their neighbor-hood. Both you and your neighbors may start in getting known to each other by introducing yourselves. This is a sign that you and your neighbors are actually friends. Instead of watching television and playing computer games all the time, you also need to take a break and have some fun talking with your neighbors. But if you want to make friends with them, you need to do something that might please them. The only problem for this situation is that you are afraid to approach and greet them in a nice way.
This is a challenge that you or your fellow neighbors must be aware of. You need to get as many friends as possible in your neighborhood, and one of them is to get closer with the unfriendly.

Now many young people are traveling around the world on their own, not because they have no one to travel with, but because they prefer to go alone.
Kristina Wegscheider from California first traveled alone when she was at college and believes that it is something everyone should do at least once in their life. “It opens up your mind to new things and pushes you out of your comfort zone.” Wegscheider has visited 46 countries covering all seven continents.
In foreign countries, with no one to help you read a map, look after you if you get ill, or lend you money if your wallet is stolen, it is challenging. This is what drives young people to travel alone. It is seen as character building and a chance to prove that they can make it on their own.
Chris Richardson decided to leave his sales job in Australia to go traveling last year. He set up a website, The Aussie Nomad, to document his adventures. He says he wished he had traveled alone earlier. “The people you meet, the places you visit, or the things you do, everything is up to you and it forces you to grow as a person,” said the 30-year-old man.
Richardson describes traveling alone like “a shot in the arm”, which “makes you a more confident person that is ready to deal with anything”. He said, “The feeling of having overcome something on my own is a major part of what drives me each day when I’m dealing with a difficult task. I walk around with my head up because I know deep down inside that nothing is impossible if you try.”
The great 19thcentury explorer John Muir once said, “Only by going alone in silence can one truly get into the heart of the wilderness.”
1.Which of the following will Kristina Wegscheider agree with?
A. Traveling alone is a necessary experience for everyone.
B. It is more meaningful to travel in foreign countries.
C. It is comfortable to travel around without a friend.
D. Traveling abroad helps people to find new things.
2.Traveling alone is challenging because ________.
A. you have to make things on your own
B. it is hard for you to prove yourself to others
C. you can only depend on yourself whatever happens
D. it will finally build your character
3.What can we infer about Chris Richardson?
A. He started traveling alone at an early age.
B. He was once shot in the arm.
C. He used to work as a salesman.
D. His website inspires others a lot.
4.What is the best title for the passage?
A. Travel Abroad B. Travel Alone
C. Travel Light D. Travel Wide and Far
