People from all over the world visit Disneyland to have fun, not to get sick. But last week， an outbreak of measles（麻疹）spread from the Southern California theme park. As of Monday, January 19, at least 52 people have got the easily spread illness.

    The majority of the reported cases of measles are from people who visited the park before. According to the California Department of Public Health, these people were exposed to the illness at Disneyland from December 17-20.

    Officials believe the cause is likely someone who caught measles abroad and visited Disneyland, but this has yet to be proved. However, in 2014, California had its highest measles infection rate in nearly twenty years. There were 66 cases of measles reported in the state―23 of them in Orange County, where Disneyland is located.

    Measles spreads very easily. It can be caught from coughing and sneezing. Crowded areas like theme parks are especially suitable for its spread.

    The illness starts with a fever and develops into symptoms including a cough， runny nose, red eyes and so on. About three out of ten people infected with measles will develop another health problem, including an ear infection or pneumonia(肺炎).

    The best way to guard against measles is to get vaccinated(打疫苗). An unvaccinated person is 35 times more likely to catch measles than someone who received a vaccination.

    You may like chewing gum (口香糖) after meals to stop your breath smelling bad; or your mother might use a special neutralizer (调理剂) to protect her permed hair (烫发). But have you thought about the chemical principles behind such everyday actions?

    On March 2, the Senior 3 students from the IB (International Baccalaureate, 国际文凭) classes at Beijing Huijia Private School presented their discoveries, all in fluent English. This kind of seminar is held every year to show the achievements of the IB chemistry experiment lessons offered by the school. IB is a qualification based on a common curriculum (课程) for students aged 16-18 in any country and is recognized by universities everywhere.

    "Once I saw an advertisement for xylitol (木糖醇) gum," recalled Zhang Xinju. "Suddenly an idea came to my mind: are there any chemical reactions when the xylitol is working on our teeth?"

    Zhang and his partner Bu Xuan visited several hospitals to try and find out. "Doctors know that xylitol can protect teeth, but few could explain how the chemical reactions happen," said the 17-year-old boy.

    Presenting the results of their research in English to an audience of Chinese and foreign judges was never a problem for the students.

    "Textbooks for IB students are in English, and our teachers speak in English," explained Wei Duan and Han Yu, whose research topic was "The Acid-Base Reaction (酸碱反应) in the process of Hair-Perming".

    "In Senior 1 we often referred to Chinese textbooks, but we found we could understand and express it all in English by the second year."

    Lu Jiang, the school's IB chemistry teacher and China's only IB vice-examiner, is proud that her students can apply scientific theories they learn in class to daily life.

    "You might have learned these facts from you kindergarten teachers, but few think about the theories behind them," Lu said. "This kind of practice is intended to develop the scientific thinking they will need in their future studies."

                                                                                          Educational Programs for Kids

    Are you interested in helping your child continue his or her education beyond the typical school day? If so, then educational programs for kids may be what you're looking for.

    Where to Find Educational Programs?

    Many kids who are struggling in school may benefit from an after-school tutoring session or homework club. Check with your child's school, your local library or the park district for a list of available programs. You can also check with the local Boys and Girls Club, YMCA, church or youth center. Depending on your child's interests and strengths, consider art, community service, drama, music, creative writing, sports, cooking or environmental programs.

    What Educational Programs Are Provided by Organizations?

    The organizations mentioned above provide educational programs for kids, such as a community your child can be a part of and programs that focus on education, health, leadership, recreation and fitness.

   Another possibility is the Boy Scouts of America or the Girl Scouts. These are two separate organizations that can potentially provide your child with a sense of accomplishment, self-confidence and belonging. Both organizations will provide your child with many learning experiences and activities both indoors and outdoors.

    What Kind of Program Is Best for My Child?

    The type of educational program that's best for your child is subjective and based on many factors, including your child's age. If your child is in primary school, educational programs can help him or her develop as a person and gain leadership skills, a sense of self-worth and the ability to cooperate with others. By the time your child is in high school, his or her involvement with educational programs and other extracurricular activates can be key elements when your child is applying to college.

    When you help your child to pick an educational program, carefully consider what your child needs and what every option offers.

    It is commonly believed that the earliest Chinese paper-cuts appeared during the sixth century. Some scholars believe it was even earlier. Legend has it that during the Western Han Dynasty(206BC-AD24), Emperor Wudi was very sad after one of his favorite concubines, Madame Li, died. A Taoist priest, Li Shaoweng, cut a piece of hemp paper in the shape of Madame Li. When evening fell, the emperor's servants lit candles in his bedroom; the reflection of that paper-cut on the wall made the emperor think about his beloved concubine.

    The Yuxian paper-cut is different from most paper-cuts produced in other regions of China. Paper-cuts from other regions are mostly cut with scissors or knives from single-colored paper, such as red or black paper.

    There are four major procedures to making the Yuxian paper-cut: First, sketch the pattern on the draft paper; second, fasten the draft to the paper to be cut; third, use a knife to carve out the pattern; and fourth, dye (染色) the paper-cut with various colors.

    Precise cutting skills are needed to make a piece of the Yuxian paper-cut, which highlights the craft maker's artistic taste and dyeing skills. That explains the following saying: "The successful making of a Yuxian paper-cut is 30 percent dependent on the maker's cutting skills, and 70 percent on the maker's dyeing skills."

    The traditional Yuxian paper-cut highlights two themes: flowers and characters in Chinese operas. The paper-cut is particularly known for its vivid description of characters in various traditional Chinese operas. In October 2009, the art of Yuxian's paper-cut was added to the list of Intangible Cultural Heritage (非物质文化遗产) established by UNESCO (United Nations Educational, Scientific, and Cultural Organization).

    A survey has shown that what you do on a plane can be determined by which nationality is listed on your passport.

    According to the results of an international passenger survey, Australians are the biggest drinkers on board with 36 percent choosing to down the hatch, compared to 35 percent of Americans and 33 percent of Brits.

    The Airline Passenger Experience Association ( APEX) spoke to around 1500 people, aged 18 and older, who have travelled by plane at least once during the last three months and were living in the United States, United Kingdom, Germany, Japan, China, Singapore, Australia or Brazil.

The results found Chinese travelers are most likely to nod off once the sea-belt sign switches off. They are also the first to reach for their credit card for some in-flight shopping and the biggest fans of gaming. Americans on the other hand like to use their time in the air more productively —when not drinking —choosing to work while flying a 350000 feet.

Meanwhile, Brits and Germans are the best at making chat with random strangers — spending 50 percent more time than any other nationality. Comparatively, Brazilians conduct their conversations online via e-mail, messaging apps or social media.

    Despite plane food having a bad reputation, seven out of ten interviewees said they were happy to eat up on the selection in-flight snacks and meals. In-flight magazines were also popular with four out of five passengers claiming to read them.

    The international flyers did however express their desire for better in-flight entertainment. “The industry has greatly improved the comfort, entertainment and onboard service, and passengers are accepting those improvements,” said Russell Lemieux, APEX executive director. “At the same time, passengers are demanding more from their air travel experiences which will drive more improvements touching all aspects of the journey,” he added.
