Unit 2 English Around the World reading课时作业第一节.阅读理解AWatching a 3D movie can more than double the concentration powers and cognitive (认知)processing of children, a new research claims.A study made by visual technology firm RealD and led by child psychologist Dr. RichardWoolfson suggests that children aged between 7 and 14 experienced twice the cognitiveprocessing speed and performed better in testing after watching 20 minutes of a 3D film. This isdespite suggestions that attention spans (时期) in children have shortened in the last decade due tounlimited access to entertainment, including ondemand TV, gaming and social media. A 2015study claimed that watching 3D content had a similar effect to braintraining exercises.Consumer psychologist Mr. Fagan said that the increased stimulation (刺激) found inwatching something in 3D “exercised” the brain and improved performance in the short term. “3Dfilms can play the role of ‘braintraining’ games and help to make children ‘smarter’ in the shortterm，” he said. “The shortening of response time after watching 3D was almost three times asbig as that gained from watching 2D; in other words, 3D helps children process aspects of theirenvironment more quickly. This is likely to be because 3D is a mentally stimulating experiencewhich ‘gets the brain's juices flowing’．”The experiment saw children given a range of cognitive tests before watching 20 minutes of amovie in either 2D or 3D and being tested again. The results showed those who saw the 3Dcontent reacted faster and performed better in the second round of testing. Mental engagementalso rose by 13% among 3D watchers. Child psychologist Dr.Woolfson added that “supportiveparenting” and regularly listening to classical music can also aid a child's memory.语篇解读：本文介绍了一项新的研究，研究表明观看3D电影可以提升儿童的注意力和认知力。1．The reason why children perform better after watching a 3D movie is that ________.A．a 3D movie makes their brain activeB．a 3D movie is more exciting than a 2D movieC．children enjoy watching a 3D movieD．children like the experience which “gets the brain's juices flowing”解析：选A　细节理解题。根据第三段最后一句可知，3D电影能够让大脑更活跃，所以孩子在观看3D电影后会表现得更好。故选A项。2．Which of the following is TRUE according to the passage?A．Only “supportive parenting” and listening to music can help a child's memory.B．The children in the experiment are tested only once.C．All the children doubled the cognitive processing speed in testing.D．Children's attention spans have shortened in the past 10 years because of access to

Alibaba is just big, even by Chinese standards.Its market attractsabout 231 million active buyers, 8 million sellers, 11.3 billion orders ayear — and Alibaba is just the middleman.It encourages people to useits markets — not charging small sellers a percentage of the sale.If you want a quick look into the influence of Alibaba on Chinese daily life, take myexperience.I moved to Beijing a year ago and quickly got tired of visiting small stores across thecrowded, polluted city of 20 million people in search of new electronics, bathroom furnishings,and anything else my wife wanted.“You're looking for what exactly？Why not try it？” myChinese teacher asked me one day.With that, my wonderful new relationship with Alibaba began.Alibaba's original businesstobusiness model now is second to consumer buying.Chinese retail(零售) buying makes up 80% of Alibaba's profit, and leading that group is Taobao, with 800million items for sale and the most unbelievable selection of things you'll never find. Tmall.com isAlibaba's another big site, where you can find brandname goods from Nike to Unilever almost atthe lowest prices.What I have a hard time explaining to friends and family back in the U．S. is how China hasgone beyond traditional shopping — bigbox retailers especially — in favor of online purchases onTaobao and a few other sites.In smaller towns than Beijing, Taobao will be the first choice whenshopping online.I have a list of some of my recent purchases on Taobao for a sense of how wide themarketplace is.Almost everything arrived a day or two after ordering with free shipping.I'm noteven a big buyer, because I need friends to help me search the Chineselanguage site.When I wassearching my purchase history on my Chinese teacher's iPad, which helps me buy goods, I lookedthrough with great difficulty about 10 of her purchases for every one of mine.语篇解读：本文主要介绍了阿里巴巴对人们的购物产生的巨大影响，它已经深入到人
