a new middle class family Personally if I have a dog I want to give it the very best of everything Otherwise I wouldn t have a dog Before we get too sentimental 引起伤感情绪的 though other dogs in China have a far more grisly 令人毛骨悚然的 fate many still destined for the dinner table dog meat a popular delicacy But appetities are changing What was once for the eating is now for the treating Beijing alone is

now D so much money has been spent on treating every dog C C Parents are often amazed at how fast their child grows and develops New research has determined that the ability to quantify may develop much sooner than most parents realize Kristy vanMarle professor of the University of Missouri has determined that contrary to what previous studies have shown infants 婴儿 are able to quantify substances 物质 like sand or water as early as 10 months As long as the difference between the two substances is large enough infants will choose the larger amount especially when it comes to food With the assistance of her team researchers vanMarle tested the quantifying skills of babies by presenting them with two cups one containing a small amount of food and one containing a larger amount Consistently the babies chose the larger amount This information further refutes 驳斥 the long held idea that babies know nothing of the world vanMarle said Since psychologists have begun studying infants with sensitive measures we ve discovered a lot of early abilities I think for parents it should be exciting to know that there s somebody in there that has some fundamental and basic knowledge of the world and that knowledge is guiding their development vanMarle said In the future vanMarle says this kind of study could be linked to a child s progress in math related skills although programs marketed to increase those abilities such as Baby Einstein still have mixed reviews when it 用心 爱心 专心 8 comes to academic study 62 The quantifying ability refers to the ability to A choose between

of buying on album Kids today have missed the beauty of taking your allowance 零花钱 money and making a decision based on the Jacket not knowing what the record sounded like he said But far from killing the industry many young people today think Jobs has been a blessing 带来幸运的人 offering you instant and selective access to a whole world of music Keith Staskiewicz at Entertainment Weekly speaks for the feelings of many music lovers He believes listening to Mp3s rather than records or CDs just saves them money and doesn t eliminate 消除 the sense of discovery they get from new music Staskiewicz also argues that it s wrong to blame Jobs and Apple for destroying anything Change is just part of the business Staskiewicz said No doubt in 50 years Justin Bieber will complain in his Rock and Roll Hall of Fame induction speech about how kids don t listen to iPods any more For now though it appears that music downloading is set to continue for the near future According to Summer Redstone chairman of media company Viacom 用心 爱心 专心 9 iTunes has resurrected 复兴 the music industry by creating a legal affordable purchasing system for fans But recent surveys suggested that despite the legalizing of music downloading via sites like iTunes young people are still choosing to download music illegally A report by Jupiter Research suggested that illegal downloading sites are used three times as much as legal ones The problem according to its analyst Mark Mulligan is how today s youth grow up viewing music as something they can get for free Unless the music industry can shift these consumers 消费者 while they are young away from free consumption to paid music formats 格式 they may never develop music purchasing behavior warned Mulligan recording industry could suffer long term harm 66 Jon Bon Jovi

young consumers instant and selective access to a variety of music 70 What is the main point of the article A How Steve Jobs and Apple changed people s music tastes B Opinions on effects of music
