When you hear the word hero， you may think of someone like Mahatma Gandhi or Nelson Mandela． But there are also "everyday" heroes一they may not be（1）　　 to the public， but they do what they can to help（2）　　 people's lives as well． Everyday heroes are normal people who are working to make the world a better place．（3）　　them is Robert Lee．

Future View

    I think it will be great if they invent something so that we only have to sleep for one or two， hours every day．Then we'd all have much more time to do．things and to enjoy ourselves． Life would be better， I think， and everyone would do a lot more with their lives．

    If I could choose anything， I'd go for a time machine so that I could go back and do some things differently． Of course，that's impossible一but wouldn't it be great if it was possible？ I wish I could go back in time to when I was a kid and say some of the things in a different way!

Well， of course， the best thing is medicine for really bad diseases（疾病）．A lot of scientists are working very hard to stop diseases like Ebola，a terrible disease that has killed many thousand people in Africa．So if they， found a special treatment for Ebola， or a way of completely preventing it，life would be easier in so many places．

    It will be great if there is some kind of fuel（燃料） we can use in cars that won't produce any pollution．I guess there are scientists right now trying to do that， and I hope they'll succeed because the world would be a much cleaner place， wouldn't it？

Is there a connection between music and language？According to recent studies，the answer is yes：Music helps develop certain language abilities in the brain．

    A study from Northwestern University shows that playing a musical instrument can improve a person's hearing ability． As a part of the study， two groups of people listened to a person talking in a noisy room．The people in the first group were musicians， while those in the second group had no musical training．The musicians were found to be able to hear the talking person more clearly．

    Musicians hear better， says study leader Nina Kraus， because they learn to pay attention to certain sounds． For example， when the violinists play in an orchestra （管弦乐队），they must listen closely to what they are playing and ignore （忽视） the other sounds． In this way， musicians can hear certain sounds better， even in a room with lots of noise．

     Gottfried Schlaug，a doctor at Harvard Medical School，works with stroke （中风） patients．Because of their illness， these people cannot say their names，addresses， or other information normally．However， they can still sing． Dr． Schlaug was surprised to find singing words helped his patients finally speak． Why does this work？Schlaug isn't sure． Music seems to be able to make different parts of the brain active， including the bad parts． In some way， this helps patients use those parts of the brain again．

    So music is not only enjoyable， but also good for us in many other ways． Playing an instrument or singing， says Nina Kraus， can help us do better in school and keep our brain sharp as we get older．

It's late evening in the middle of the winter． The snow is deep， but off I go into the wild．Suddenly， I hear it： the howl （嚎叫） of wolves． Excitedly， I walk faster in the direction of the howling．

    I've been working as a volunteer wolf tracker in Yellowstone National Park for over a year． It's my job to follow wolves to record information about them． Like wolves， however， I don't work alone． I'm one of a team of people who have been in a project to help reintroduce wolves to the park．

    Humans have always feared wolves． From fairy tales to movies， the wolf is always the bad guy a danger to humans and other animals． In the 1920s， the organizers of the park shared this view about wolves and made the decision to drive them away from the park．As a result，the number of elk（麋鹿）in the park increased． The elk started looking for food near river banks since they didn't have to worry about wolves．This， in turn， stopped trees from growing along the rivers， doing great harm to the environment there．

    The return of wolves has already made a big difference． To begin with， the elk soon learned to stay away from the rivers， so new trees have been able to grow there． The trees become home to new wildlife， such as birds， and provide food for more animals．

    The park is now becoming more and more popular with those who want to see wolves in their natural environment． It has also helped the local people make more money， Tourists visit the area，stay in the local hotels， and eat in the local restaurants．

    Looking at the wild animals and the beautiful sceneries around me， I am amazed at the changes the wolf has made to Yellowstone． And happily， it is playing a good guy in this story．

Whenever I'm invited to somebody's house for the first time， I'll take a close look at their bookshelves．What they keep on their shelves，in my eyes，is a reflection （反映） of their personal tastes and interests．The books on a bookshelf tell the story of a life．

    My own shelves are a kind of roadmap through my life， telling a chronological tale． First up come my favorite childhood reads， like Watership Down and His Dark Materials． The collection then moves on to teenage things I read in school ﹣ Nineteen Eight﹣Four， The Handmaid's Tale and A Clockwork Orange． Finally， we come out of full﹣time education and enter the real world， and this part is a reflection of my professional （职业的） life， from the first exciting days of work experience to the present．
