Turns out we aren’t good at walking and talking at the same time, according to a study of pedestrians （行人） on their cell phones．

     Nearly one-third of pedestrians （29．8% ） were distracted （分散注意力） by their mobile  devices while crossing the street, say researchers of a study published online in the journal Injury Prevention．

     Just as drivers who text, talk on cell phones, or adjust MP3 players increase their risk of losing control of their vehicles, pedestrians distracted by their conversations or their devices also put themselves at higher risk of getting into an accident．

    During the summer of 2012, scientists in Seattle, Wash． , studied 1,102 pedestrians at 20 crossroads seeing the city * s highest number of pedestrian injuries over the past few years．

    They watched how pedestrians crossed the street @ whether they looked both ways or obeyed the crossroad signal @ and also recorded how long it took pedestrians to do so． Distractions included listening to music with headphones, using a cell phone or earpiece to talk on a cell phone, text messaging, and talking with another person．

    Overall, researchers found the most common distraction among pedestrians was listening to music （11．2%）, followed by text messaging （7．3%）, and using a handheld phone（6．2%）． But the most absorbing distraction was texting． Compared to pedestrians who were not distracted, those who were texting took 1．87 seconds longer to cross and were four times more likely to not look where they were going, disobey traffic lights, or cross outside of the crosswalk． While the study did not track injuries related to these trends, previous studies have linked such activities to a higher risk of being injured while crossing the street．

    Combined with the rise in the use of mobile devices, especially smart phones, the results raise concerns that multi-tasking while walking may be a rising concern for pedestrians． And that danger may only climb, as the number of wireless devices has already exceeded the population of the United States． Last year, roughly 1,152 people wound up in the emergency room to treat injuries caused by using a cell phone or electronic device, the Consumer Product Safety Commission told the Associated Press in July． Those numbers may be underestimated, however, because patients may not always admit that they were using their phones along with other activities such as walking or driving when they were hurt．

【小题1】Which of the following is unlikely to be considered by a housewife who hates washing sticky cookers?

Five Olympic mascots were announced exactly 1000 days before the Beijing Olympic opening ceremony. The long--anticipated mascots represent four of China's most popular animals — the fish, the panda, the Tibetan antelope and the swallow .The fifth mascot is the brightly burning Olympic flame.
Each of the mascots has a repeated two-syllable name. This type of name is a traditional way of showing affection for children in China. BeiBei is the fish, JingJing is the panda, HuanHuan is the Olympic flame, YingYing is the Tibetan antelope and NiNi is the swallow. The first characters of their two-syllable names read “Beijing Huanying Ni,” or, in English, “Welcome to Beijing.” 
The five elements of nature, including the sea, forest, fire, earth and sky are found in the mascot's origins and headpieces. These special headpieces also display the folk and culture of China. Each mascot also symbolizes a different blessing ---prosperity, happiness, passion, health and good luck.
It is the first time more than three mascots will share the important duty of representing their host country. Han Meilin, chief of the mascot design team explained that, “China has such a rich culture that no single mascot could possibly represent it! That is why we chose to produce five mascots instead of one.”
Called the “Five Friendlies,” the figures embody（体现） the Chinese people’s hope for peace and friendship in the world and the spirit of the Olympics, representing not only multi-ethnic(多民族的) cultures of China, but also the traditional Chinese philosophy of harmony between humans and nature.
In order to help Beijing 2008 spread its theme of One World, One Dream to every continent, the Five Friendlies reflect the deep desire of the Chinese people to reach out to the world in friendship through the Games — and to invite every man, woman and child to take part in the great celebration of human union in 2008.
