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 modem 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 lime, 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 tarmac roads (柏油路). As wheel design took off, vehicles got faster and faster.
【小題1】What might explain why transport wheels didn't become popular for some time?
A.The existence of transport wheels was not known. |
B.Humans carried farming tools just as well. |
C.Animals were a good means of transport. |
D.Few knew how to use transport wheels. |
A.It provided conditions for wheel design to develop. |
B.It was easier than wheel design. |
C.It was promoted by fast-moving vehicles. |
D.It improved after big changes in vehicle design. |
A.By giving examples. |
B.By making comparisons. |
C.By following time order. |
D.By making classifications. |
A.The beginning of road design. |
B.The history of public transport. |

Cold weather can be hard on pets, just like it can be hard on people. Sometimes owners forget that their cats are just as used to the warm shelter as they are. Some owners will leave their animals outside for a long period of time, thinking that all animals are used to living outdoors. This can put their pets in danger of serious illness. There are things you can do to keep your animal warm and safe.
Keep your pets inside as much as you can when the weather is bad. If you have to take them out, stay outside with them. When you’re cold enough to go inside, they probably are too. If you must leave them outside for a long time, make sure they have a warm, solid shelter against the wind, thick bedding, and plenty of non-frozen water.
If left alone outside, dogs and cats can be very smart in their search for warm shelter. They can dig into snow banks or hide somewhere. Watch them closely when they are left outdoors, and provide them with shelter of good quality. Keep an eye on your pet’s water. Sometimes owners don’t realize that a water bowl has frozen and their pet can’t get anything to drink. Animals that don’t have clean and unfrozen water may drink dirty water outside, which may contain something unhealthy for them.
【小題1】What do we learn about pets from Paragraph 1?
A.They are often forgotten by their owners. |
B.They are used to living outdoors. |
C.They build their own shelters. |
D.They like to stay in warm places. |
A.To know when to bring them inside. |
B.To keep them from eating bad food. |
C.To help them find shelters. |
D.To keep them company. |
A.run short of clean water | B.dig deep holes for fun |
C.dirty the snow nearby | D.get lost in the wild |

Driving to a friend’s house on a recent evening, I was attracted by the sight of the full moon rising just above my friend’s rooftop. I stopped to watch it for a few moments, thinking about what a pity it is that most city people --- myself included --- usually miss sights like this because we spend most of our lives indoors.
My friend had also seen it. He grew up living in a forest in Europe, and the moon meant a lot to him then. It had touched much of his life.
I know the feeling. Last December I took my seven-year-old daughter to the mountainous jungle of northern India with some friends. We stayed in a forest rest house with no electricity or running hot water. Our group had campfires outside every night, and indoors when it was too cold outside. The moon grew to its fullest during our trip. Between me and the high mountains lay three or four valleys. Not a light shone in them and not a sound could be heard. It was one of the quietest places I have ever known, a bottomless well of silence. And above me was the full moon, which struck me deeply.
Today our lives are filled with glass, metal, plastic and fiber-glass. We have television, cell phones, pagers, electricity, heaters and ovens and air-conditioners, cars, computers.
Struggling through traffic that evening at the end of a tiring day, most of it spent indoors, I thought, “Before long, I would like to live in a small cottage. There I will grow vegetables and read books and walk in the mountains. And perhaps write, but not in anger. I may become an old man there, and wear the bottoms of my trousers rolled and measure out my life in coffee spoons. But I will be able to walk outside on a cold silent night and touched the moon.”
【小題1】The best title for the passage would be _________.
A.Touched by the Moon |
B.The Pleasures of Modern Life |

With large and small keyboards everywhere, neither children nor adults need to write much of anything by hand. That’s a big problem. Study after study suggests that handwriting is important for brain development — helping kids get fine motor skills and learn to express and create ideas. Yet the time devoted to teaching penmanship in most schools has shrunk to just one hour a week. Is it time to give up handwriting? Have a look at the link between the brain and penmanship, and you may get the answer.
A test among students in grades 2, 4 and 6 found that they not only wrote faster by hand than by keyboard, but also created more ideas when composing essays with handwriting. And other research shows that the finger movements required to write by hand activate brain areas involved with thought, language, and short-term memory.
A recent Indiana University study had one group of children practice writing letters by hand while a second group just looked at those letters. Then, both groups of kids entered a functional MRI (核磁共振) that scanned their brains as the researchers showed them the same letters. Researchers found that the brain activity in the first group was far more advanced and “adult-like”.
Handwriting also affects other people’s way they think of adults and children. Several studies have shown that the same average essay will score much higher if written with good penmanship and much lower if written out in poor handwriting. These studies have also found that people judge the quality of a person’s ideas based on his or her handwriting. And the consequences are real: On standardized tests with handwritten sections, like the SAT, all essay that is considered hard to recognize gets a big zero.
Studies show that this isn’t only an English-language phenomenon. Chinese and Japanese youths are suffering from “character amnesia”. They can’t remember how to write characters, thanks to computers and text messaging. Some experts fear that Chinese writing and reading are so closely linked in the brain that China’s reading ability as a nation could suffer.
【小題1】According to the passage, it can be learned that ________________.
A.many researches have been done on handwriting |
B.essays can’t be composed without handwriting |
C.a(chǎn)ll children write faster by keyboard than by hand |

By 2050 there will have been an extra 2.5 billion people on earth. And what will they eat?
To solve the problem, we should have to double our food production. We can also develop a diet of algae(海藻), insects and meat grown in laboratories.
Algae can grow very quickly at sea, in polluted water and in places that would normally kill food crops. They are already eaten widely in Japan and China and they are eaten by almost everything from shrimps to blue whales. They can fix CO2 in the atmosphere and provide fats and sugars.
Man-made meat looks like meat, feels like meat and it is meat, although it’s never been from a living, breathing animal. Instead, it is grown from cells in big containers. Moreover, studies show that producing man-made meat will use far less water, energy and land.
China has developed “green super rice”, a series of rice types which produce more grain and have stronger ability to fight against floods, salty water, insects and disease. We used traditional plant breeding(作物育種)techniques to cross-breed more than 250 rice types. Green super rice, which is enough to feed an extra 100 million people, will be planted widely in the coming years.
Insects like ants are not on most European menus but at least 1,400 kinds are eaten across Africa, Latin America and Asia. Now, with rising food prices and worldwide land shortages, such insects are getting more and more popular. Not only are many insects rich in protein(蛋白質(zhì)), low in fat and high in Ca and Fe, but insect farms need little space. And they can grow well on paper, algae and industrial wastes.
【小題1】In order to exist in the future, people have to _______.
A.move to other planets |
B.produce rain in laboratories |
C.build new laboratories for food research |
D.increase the food production or look for other food sources |
A.a(chǎn)lgae have a strong life force |
B.few people eat algae now |
C.a(chǎn)lgae have few values for human beings |
D.a(chǎn)lgae can pollute our environment |
A.has to be watered with salty water |
B.can grow even in a bad environment |
C.includes no more than 250 rice kinds |
D.was developed with new technologies |
A.Green super rice is delicious but high in price. |
B.In Asia about 100 million people may be faced with food shortages. |
C.Man-made meat doesn’t look like meat but has the same taste as real meat. |
D.One of the reasons why many people begin to eat insects is their rich food value. |

Why is pink or purple a color for girls and blue or brown for boys?
The answer depends largely on cultural values as well as personal experiences. To the Egyptians, green was a color that represented the hope and joy of spring, while for Muslims, it means heaven. Red is a symbol of good luck in many cultures. In China, children are given money in a red envelope to bring good fortune in the New Year. For many nations, blue is a symbol of protection and religious beliefs. Greek people often wear a blue necklace hoping to protect themselves against evils (災禍).
People’s choice of colors is also influenced by their bodies’ reactions (反應) toward them. Green is said to be the most restful color. It has the ability to reduce pain and relax people both mentally and physically. People who work in green environment have been found to have fewer stomachaches.
Red can cause a person’s blood pressure to rise and increase people’s appetites (食欲). Many decorators will include different shades of red in the restaurant. Similarly, many commercial websites will have a red “Buy Now” button because red is a color that easily catches a person’s eye.
Blue is another calming color. Unlike red, blue can cause people to lose appetite. So if you want to eat less, some suggest that eating from blue plates can help.
The next time you are deciding on what to wear or what color to decorate your room, think about the color carefully.
【小題1】Muslims regard green as a symbol of heaven mainly because of their .
A.cultural values | B.commercial purposes |
C.personal experiences | D.physical reactions to the color |
A.To relax people physically. |
B.To increase people’s appetites. |
