The holiday season isn't just about shopping and gifts. {#blank#}1{#/blank#} However, holiday travel can be more expensive than the gifts. Fortunately, the following tips will help keep your travel spending under control.

● Plan ahead. The earlier you book your travel, from airfare to hotels, the easier it is to find good deals. {#blank#}2{#/blank#} Your best prices on airfare come when you book three weeks before the plane leaves for domestic flights. For international flights, consider booking 30 days in advance. Many experts point out that you should book travel between  one month and three months out for high-traffic holidays.

● Book your air travel on cheaper days. Traveling by air on Tuesdays and Wednesdays often costs less than traveling on Fridays and Sundays. During the holidays, it is not just about a specific day of the week. You also need to consider the days surrounding the holiday but days immediately before and after a holiday can be expensive. One of the best ways to save is to plan your air travel on the Day of the holiday. {#blank#}3{#/blank#}

● Consider traveling overnight. Red-eye flights and overnight flights often cost less than those at more convenient times. {#blank#}4{#/blank#}Traveling overnight can help you avoid a night in the hotel, as well as save your money on travel to your destination.

●{#blank#}5{#/blank#} You can't bring liquids with you on the airline, but you can bring sandwiches and other snacks. When you are on the road, you can buy food at local groceries to make your own meals. If you are staying in a hotel long-term, consider cooking your own food, especially if you have access to a microwave.

    In addition to the official basketball world, various other types of basketball are practiced around the world.

Wheelchair Basketball

    Wheelchair basketball was invented in 1946 by former American basketball players, who, after wartime injury, wanted once again to experience the excitement of a highly athletic sport within a team environment. It is now played in more than 80 countries by over 25,000 men, women and children with a physical disability which prevents them from playing competitive basketball on their feet.

Beach Basketball

    Beach basketball is an exciting, non-stop action game played in the sand. The game was born more than forty years ago on the physical education fields of Gulf Shores School. This kind of basketball, invented by Philip Bryant, has grown from an extremely effective skill improvement game to a very popular, widespread competitive sport.

Street Basketball

    Street Basketball or streetball is mainly played as a leisure game, but streetball players can also compete against each other. There are no specific streetball rules and the game is played outdoors; the players make up their own rules to play. Streetball is very popular among younger players and allows players to publicly show their own individual skills.

Deaf Basketball

    Basketball for the deaf (unable to hear in one or both ears) men and women has been played since the early 1920s. The game today has exactly the same rules as FIBA (International Basketball Federation).

Bankshot Basketball

    Bankshot is a new game of skill and challenge that is often described as “mini golf, but with a basketball.” Bankshot is the only sports system that allows the able-bodied and athletes with a disability to play together at the same time. This game is about no running, jumping, or body contact(接触)and relies on the shooting skill.

    Whenever we see a button, we are eager to press it because we know something will happen. This is true in most cases, for example on a doorbell and on the "on/off" button on the TV. But some buttons are actually fake, like the "close" button on a lift.

    Many people are in the habit of pressing the "close" button because they don't have the patience to wait for the lift doors to shut. But lifts' "close" buttons are a complete scam (骗局), at least in the US-the doors will not close any faster no matter how hard you press.

    It started in the 1990s when the Americans with Disabilities Act was passed in the US, making sure that all lifts stayed open long enough so that people with disabilities could enter. Only US firefighters and repairmen can use the buttons to speed up the door-closing process if they have a code or special keys.

    But to normal lift riders, the buttons aren't completely useless. According to psychologists, fake buttons can actually make you feel better by offering you a sense of control.

    "Perceived (能够感知的) control is very important. It reduces stress and increases well-being," Ellen J. Langer, a psychology professor, said, "having a lack of control is associated with depression（沮丧）."

    Experts have revealed that a lot of buttons that don't do anything exist in our lives for this same purpose. For example, many offices in the US have fake thermostats (温度调节器) because people tend to feel better when they think they can control the temperature in their workplace.

    Pedestrian(行人) crosswalk buttons don't live up to their names either. Pressing them used to help make the traffic signals change faster, but that was before computer-controlled traffic signals were introduced.

    But psychologists found it interesting that even when people are aware of these little "white lies", they still continue to push fake buttons because as long as the doors eventually close, it is considered to be worth the effort.

    "That habit is here to stay," John Kounios, a psychology professor, said. "Even though I have real doubts about the traffic light buttons, I always press them. After all, I've got nothing else to do while waiting. So why not press the button in the hope that this one will work?"

    Is Paperless Office Really Paperless?

    A rising economy increased paper sales by 6 to 7 percent each year in the early to mid-1990s, and the convenience of desktop printing allowed office workers to indulge anything and everything. In 2004, Ms. Dunn, a communications supplies director, said that plain white office paper would see less than a 4 percent growth rate, a primary reason for which is that some 47 percent of the workforce entered the job market after computers had already been introduced to offices.

    For office innovators, the dream of paperless office is an example of high-tech arrogance（傲慢）. Today's office service is overwhelmed By more newspapers than ever before. After decades of development, the American government can finally get rid of the madness on paper. In the past, the demand for paper has been far ahead of growth in the American economy, but the sales have slowed markedly over the past two to three years, despite the good economic conditions.

    “Old habits are hard to break,” says Ms. Dunn. “There are some functions that paper serves where a screen display doesn't work. Those functions are both its strength and its weakness.” Analysts attribute the decline to such factors as advances in digital databases and communication systems. Escaping our craving for paper, however, will be anything but an easy affair.

    “We're finally seeing a reduction in the amount of paper being used per worker in the workplace,” says John Maine, vice president of a paper economic consulting firm. “More information is being transmitted electronically, and an increasing number of people are satisfied that information exists only in electronic form without printing multiple backups.”

    To reduce paper use, some companies are working to combine digital and paper capabilities. For example, Xerox is developing electronic paper: thin digital displays that respond to a stylus, like a pen on paper. Marks can be erased or saved digitally. Even with such technological advances, the increasing amounts of electronic data necessarily require more paper.

    “The information industry today is composed of a thin paper crust surrounding an electronic core,” Mr. Saffo wrote. The growing paper crust is most noticeable, but the hidden electronic core is far larger and growing more rapidly. The result is that we are becoming paperless, but we hardly notice at all. “That's one of the greatest ironies of the information age,” Saffo says. “It's just common sense that the more you talk to someone by phone or computer, it inevitably leads to a face-to-face meeting. The best thing for the aviation industry was the Internet.”

    Australia was first used as an island prison by Britain to solve their problem of having a fast growing prison population. These early settlers were those who were sent from all over Great Britain, including Ireland, Wales, and Scotland. Later events, such as the gold rush, caused several waves of immigration (移居) from Europe, Asia and other parts of the world. It is commonly thought that Australians are offspring (后代) of those criminals (罪犯)! In fact, only a part of Australians are those criminals' offspring. Also, in those days, people could be put into prison or sent to Australia for small crimes, like stealing a loaf of bread. Today Australia is home to the largest Greek and Italian communities in the world, outside Greece and Italy. This has helped the Australian accent develop.

    Australian English was created by the first generation of children born in the new area. Since they talked with people who have different accents, they began to speak a distinct dialect of English that was to become the language of the nation. These differences were first noted by late arrivals in the early 1800s, and the language sounds like Cockney English, spoken by the working­class in London.

    Soon, words from native languages were to become part of the Australian English. Here are some words you may consider them to be Standard English. In fact, they are from native Australian languages!

    The names of many places and animals, including Canberra (the Australian capital, meaning "meeting place" in a local language).

    Hard yakka — meaning "hard work", coming from the language of the Brisbane area.

    Cooee — a call used traditionally by native Australians to attract attention, because the sound can travel long distances.

    Bung — meaning "dead", but also used to mean broken or useless, for example, "He has a bung eye".

The ancient Chinese built two great engineering wonders: the Great Wall and the Grand Canal. Though the Great Wall's effect in military {#blank#}1{#/blank#} (defend) has worn off over time, the Grand Canal remains an important channel of cultural communication.

The Grand Canal, {#blank#}2{#/blank#} is made up of three parts (Suitang Grand Canal, Beijing Hangzhou Grand Canal and Zhedong Grand Canal), is a {#blank#}3{#/blank#} (run) epic (史诗) of transformation. The man-made waterway runs more than 2,000 kilometres from north to south across the large eastern flatland of China. It is about 16 times {#blank#}4{#/blank#} size of the Suez Canal in Egypt and 33 times {#blank#}5{#/blank#} (long) than the Panama Canal, the world's second- and third-largest man-made waterways. "It sees the striking and early development of water engineering," the UNESCO website says {#blank#}6{#/blank#} (official).

In ancient times, the Grand Canal served {#blank#}7{#/blank#} the key waterway for grain transport and every kind of economic and cultural exchange. It also improved the time-consuming journeys of workers {#blank#}8{#/blank#} materials for the building of the Forbidden City in Beijing, the imperial city of the Yuan (1271-1368), Ming and Qing (1644-1911) dynasties.

Years ago, it {#blank#}9{#/blank#} (inspire) the name of Chenchen, one of the three mascots (吉祥物) of the Hangzhou Asian Games. Chenchen, from the Gongchen Bridge, which goes across the Hangzhou part of the Grand Canal, is coloured blue {#blank#}10{#/blank#} (suggest) science and technology.
