Every evening, 15-year-old Rashida returns home from school,changes out of her uniform, and rushes to a neighboring farm to help her motherharvest vegetables. Her father is disabled, so the modest profit the two ofthem earn must cover food, clothing and other necessities for all sevenchildren and their parents. Despite having precious little time to study,Rashida is one of the top students at her junior secondary school. But with somuch responsibility on her small shoulders, she admits that it is sometimeshard for her to imagine a more promising future.

Last year, Rashida was invited to join 155 other girls at CamfedGhana's first Girls' Career Camp, a program designed to inspire girls growingup in the country's Northern Region to dream big, and to support them to pursuethose dreams. “We organized this camp because we wanted to let girls know thateven if they are struggling with poverty, their lives will not be defined bylimitations,” says Dolores Dickson, Camfed Ghana's Executive Director.

    Over the course of five days, the camp led the junior andsecondary school students through a range of experiences and career opportunities that were entirely new to them. Dr. Agnes Apusiga, a lecturer from the University of DevelopmentStudies, ran the workshop on goal-setting and career choices, describing theuniversities and training colleges in Ghana that could help them achieve theirdreams. Participants then visited the University for Development Studies, wherethey toured the medical school and science labs. Another highlight was aworkshop at the computer lab at Tamale Secondary School. Many of the girls hadstudied information technology from a book but had never before seen acomputer.

   “When the girls arrived at camp, they were not ambitious,because they didn't have any idea what the world held for them,” says EugeniaAyagiba, Project Officer with Camfed Ghana. “Many had scarcely traveled beyondtheir own villages.”

“I think the most important thing that happened at the camp isthat we opened a window of hope for a group of girls coming from backgrounds ofpoverty,” says Eugenia. For Rashida, who has been laughed at in the past by herschoolmates because of her father's disability, the experience was important.“She told one of the camp mentors(辅导员) that whenshe is at school, she often feels like a misfit, and she prefers to keep toherself,” says Eugenia. “But at the camp, it was different. She made friendswith girls who have similar struggles. She took part in every single activity,every single game. On the last day, she said to her mentor, ‘The camp haschallenged me to study hard. Now I see that there is light at the end of thetunnel.'

    Machu Picchu is an unusual site in Peru and one of the most mysterious wonders of the world. Built at almost 10,000 feet on the top of an Andean mountain, the Incas built hundreds of structures made of stone. A large number of Machu Picchu's surrounding structures date back to the early 13th century, but it was considered a chief sacred site far before then. The Inca people changed the large site into a very small but wonderful city, completely self-sufficient and hidden from below. Agricultural terraces (梯田) surrounded the entire city, fed by natural spring water, supporting the entire population.

Inca Trail

    The trail is one of the most famous in the world and regarded as one of the best. It covers only 26 miles, combining cloud forest, green mountain scenery, forest, and plenty of tunnels, paving stones, and ruins. The four-day hike begins slowly but quickly changes into a difficult journey suitable for those in excellent shape. The trail winds through the Andes, leading alongside and through ruins. Though independent hiking was once permitted, now it must be done with a guide.

Funerary Rock

    It is believed that the Funerary Rock at Machu Picchu was used as a place to prepare Inca nobles for preservation, or mummifying (做成木乃伊), a common habit among the tribe. Nobles would be laid out to be mummified by the hot sun and freezing cold nights after their organs were removed. The rock is also famous as a spot from which a view of the city is afforded.

Temple of the Sun

    Within the city's castle, deep within Machu Picchu, is the Temple of the Sun, accessed only by the Emperor and

    Inca priests. It means the Inca's advanced knowledge of religion, weather, and nature, showing the great extent

    Incas went to adapt to and learn about nature. Still unbroken, the temple was built to honor the god Inti, who is exactly the sun. The temple was effectively protected. It was also a very important scientific center, built in half-moon shape with openings facing north and east. The windows' shadows in the center of the temple helped see the start of winter solstice (至日), showing farming season.

    Women are friendly. They often share with others. But men are more competitive. They are trying to improve their social status. Why? Researchers have found it's all due to the hormone oxytocin (荷尔蒙催生素). Although known as the love hormone, it affects the sexes differently.

    Generally, people believe that the hormone oxytocin is let out in our body in various social situations and our body creates a large amount of it when falling in love or giving birth.

    But in a former experiment Professor Ryan found that the hormone is also let out in our body during a negative situation such as envy (嫉妒).

    Further researches showed that in men the hormone oxytocin improves the ability to recognize competitive relations, but in women it raises the ability to recognize friendship.

    Professor Ryan's recent experiment used 62 men and women aged 20 to 37.

    Half of the participants (参与者) received oxytocin. The other half received placebo (安慰剂).

    After a week, the two groups switched with participants. They went through the same steps with the other material.

    Following each treatment, they were shown some video pictures with different social behavior. Then they were asked to analyze the relations by answering some questions. The questions were about telling friendship from competition. And their answers should be based on gestures, body language and facial expressions.

    The results showed that, after treatment with oxytocin, men's ability to correctly recognize competitive relations improved, but in women it was the ability to correctly recognize friendship that got better.

    Professor Ryan thus concluded, “Our experiment proves that the hormone oxytocin can raise people's abilities to better tell apart different social behaviors.”

    Here are some recommendations for tourists to choose from.

    Banff, Canada

    Banff, located in the Rockies, has a view of tall mountains, deep valleys and lakes, making it the first town to become part of the country's national parks. Tourists can enjoy its beauty by hiking, horse riding and boat trips. Banff was founded in 1883 while a railroad was in construction. It was the water springs that drew the engineers' attention to the place as a settlement. With such a fantastic view, it's no surprise that Banff hosts a number of cultural festivals.

    Lisbon, Portugal

    Lisbon is the capital of Portugal, with the warmest winters of any major European city.

    Belem Tower and Jeronimos Monastery are listed as UNESCO World Heritage Sites. The former was built in the 16^th century as a symbol of Portugal's Extraordinary Age and the latter is one of the greatest examples of the Portuguese late-Gothic style of architecture. The Lisbon Oceanaium is among Europe's finest aquariums. The Museum Calouste Gulbenkian is among the best museums in Europe containing priceless artworks covering 4000 years from ancient Egyptian times to the late 20^th century.

    Portland, US

    Portland is frequently recognized as one of the world's most environmentally-friendly cities because of its well-built pavements, large community of cyclists and convenient public transportation. Us climate is ideal for growing roses and it's called the “City of Roses”. Besides, the seaport is also known as a city of beer: it has the largest number of beer breweries（啤酒厂）of any city in the world. Today's Portland is better known for its music. It's called “the capital of karaoke” and “one of the most exciting music scenes” in the US.

    Bordeaux, France

    Bordeaux attracts tourists with its rich cultural heritage, especially its wealth of architectural treasures. Besides the Cathedral of Saint Andrew dating back to 12^th century, the Basilica of Saint Michael is another one of the city's UNESCO World Heritage Sites. It took 200 years to build from 14^th to 16^th centuries. Other significant buildings include the Grand Theater built in 1780 in the new Classical style and the Stone Bridge built in 1821.

    With the New Year just months away, you are probably looking forward to watching the wonderful fireworks(烟花) shows. Unfortunately, the over ten million blind Americans, and scores more around the world, have never been able to experience this joyful celebration. That may change soon thanks to Feeling Fireworks, a tactile(可触摸的) fireworks experience invented by the masterminds at the Disney Research Lab in Switzerland.

    To experience the show, users stand in front of a large screen, which is made of special material. They then place their hands at the base of the screen and move them around to feel the fireworks. Alternatively, their hands can be placed in the center of the screen, where the initial explosions happen, and then moved across to explore other fireworks.

    As the fireworks begin to explode, one of five nozzles(喷嘴) at the back of the screen starts to send out water, creating shaking movements. One specializes in the “blooming(开花) flower effect,” while another reproduces the“crackle(噼啪声)” effect. The rest take care of rockets and explosions. A computer controls the timing, while a Microsoft Kinect camera tracks the person's movement. According to the inventors, Feeling Fireworks allows users to experience “tactile fireworks that are similar to physical fireworks happening in the sky.”

    First appearing at the User Interface Software and Technology conference held in Quebec City, Canada from October 22 to October 25, 2017, the low-cost technology is still in its early stage, with only a 66 percent success rate. However, the team plans to continue-improving the experience and believes the day when everyone will be able to enjoy the thrill of fireworks shows is not far. When ready, Feeling Fireworks will initially be available only at Disney theme parks, and then hopefully, at fireworks shows worldwide.

    As the international demand for narrative films （纪录片）continues to increase with popular streaming services like Netflix and others, the two questions then come： Will the coming generations receive most of their entertainment through visual means rather than through the written word? Will such an increase of narrative film reduce the importance of reading?

    Growing examples of this trend include the dimishment(减少)of fiction lovers, the ever­rising culture of computer games, the wave of streaming services of wide international reach, and movies filled with special effects made for children and teenagers. Nor must we ignore the economic dangers that lie ahead for the written word. The narrative film industry is a moneymaker that surpasses the publishing industry.

    The other underlying question, of course, is "does it really matter if the written word bows to the world of narrative films?" From my point of view, any diminishment of fiction delivered by words is a loss for mankind.

    There is no greater human feature than the imagination. It lies at the very soul of the human species. It is the brain's most powerful engine. It is the essential muscle of life and like all muscles it must be exercised and strengthened.

    Writing and reading are the principal tools that inspire and create our imagination. Anything that diminishes that power is the enemy of mankind.

    It should be known that I am not opposed to new media and technological advances. Instead, I have always felt it necessary to adapt to advancing technology. In fact, a number of my novels are in various stages of development for film, TV and live stage productions. My hope is that the written word will only stand to be complemented(补充) by technology, not pushed to the edge of extinction.

    Of course, there are those who will present arguments for the superiority of the moving image over the written word. Each has its place. My argument is for finding the right balance between it and the moving image.
