14.Children who spend more time outdoor may have a lower risk of becoming near-sighted,new research suggests.
   In the study,researchers looked at about 1,900 schoolchildren in China.The scientists found that the kids who had been instructed to spend more time outdoors over three years were 23 percent less likely to develop near-sightedness during this time than those who had not been instructed to spend more time outdoors.Moreover,among the kids who did become near-sighted during the study,the degree to which their eyesight worsened was slightly smaller among those who spent more time outdoors.
   In the study,the researchers selected six schools and required the children,whose average age was 7 at the start of the study,to attend one additional 60-minute class of outdoor activities during each school day for three years.The parents of these children were also encouraged to engage(使参加) their children in outdoor activities after school,especially during weekends and holidays.The other half of the children,from another six schools,continued their usual activity patterns.
   After three years,30.4 percent of the kids in the intervention(干预) group had become near-sighted,compared with 38.5 percent of the kids in the control group,the researchers found.
   The reduction in the risk of near-sightedness found in the study is important,because children who develop near-sightedness at a young age are most likely to develop worse myopia (the medical term for near-sightedness) later on,the researchers said.
It is not clear exactly why spending more time outside would benefit children's eyesight.However,some research has suggested that the higher levels of light intensity found outdoors may increase the release of the chemical dopamine from the retina(视网膜) of the eye,which is beneficial to eyesight.In turn,dopamine is known to inhibit the type of growth in the eye that is associated with myopia.
Based on the new results,the researchers recommend that children spend more time outdoors because of the potential benefits to their eyesight.However,it's important to protect kids'skin and eyes from UV light,which can be damaging.

12.Blogging has become something of a big thing in the last few years.Just like the Internet was 10years ago,blogging is popular with an underground culture that is doing it for love and passion.
Blogging is a way of collecting links to webpages and sharing thoughts and ideas with people online.Blogs are basically online journals or diaries which are created for sharing information and ideas.
Dominic,a fifth-grade student,writes:"The blogs give us a chance to communicate between ourselves and inspire us to write more.When we publish on our blog,people across the entire world can respond by using the‘comments'link.In this way,they can ask questions or simply tell us what they like.We can then know if people like what we write and this indicates to us where we can improve.By reading these comments,we can discover our weaknesses and our strengths.Blogging is an opportunity to exchange our points of view with the rest of the world rather than just people in our immediate environment."
Blogging is sweeping the Internet.A recent report noted that at least three million Americans have created blogs,with similar numbers being seen worldwide.
Two years ago,Andrew Sullivan decided to set up a Web page himself and used"Blogger.com"to publish some daily musings(冥想) to a readership(读者人数) of a few hundred.He worked hard at the blog for months for no financial reward.But the result is that he is now reaching almost a quarter of a million readers a month and making a profit.
Think about it for a minute:Why not build an online presence with your daily musings and then tell your first book through print-on-demand(POD) technology direct from your Web site?Why should writers go to newspapers and magazines to get an essay published when they can simply write it themselves,change it into a PDF file,and charge a few bucks per download?
This,at least,is the idea:a publishing revolution more profound than anything since the printing press."Blogger.com"could be to words what Napster was to music-except this time,it'll really work.

58.Which of the following statements is true according to the passage?B
A.Blogs are mainly online chatting with others.
B.Blogging is important in the past few years.
C.Dominic wants to get a chance to be a writer.
D.Blogging makes us exchange our view only with friends
59.According to the passage,aboutC people worldwide have created blogs except Americans.
A.250,000        B.750,000     C.3million    D.6million
60.From the passage we can see that"Napster"in the last paragraph is probably related toD.
A.newspapers      B.readers      C.words     D.music
61.What would be the best title of this passage?C
A.What is Blogging                  B.Blog is Your Favorite
C.Blogging Goes Mainstream          D.A Publishing Revolution.
