5．Perhaps you have heard a lot about the Internet，but what is it？
The Internet is many different networks（网络） around the world．A network is a group of computers put together．These networks joined together are called the Internet．
Maybe that doesn't sound interesting．But when we've joined the Internet，there are lots and lots of things we can do．We can have a lot of interest on the World Wide Web（WWW）．We can use the Internet instead of a library to find all kinds of information about our favorite sports or film stars and doing shopping on the Internet．We can also send messages to other people by e-mail．It is much cheaper and quicker than calling our friends or sending a letter．
Thanks to the Internet，the world is becoming smaller and smaller．People can work at home with a computer in front，getting and sending the information they need．They can buy or sell whatever they want by the Internet．But do you know 98% of the Information is in English？So what will English be like tomorrow？

A．the Internet
B．information
C．e-mail

解答 46．A根据第一段及下文描述，可知这篇短文主要讲的就是互联网．故选A．
47．A根据第三段原句We can also send messages to other people by e-mail．It is much cheaper and quicker than calling our friends or sending a letter．可以得出最快最便宜的方式当然是使用电子邮件．故选A．
48．C根据第三段的描述，互联网可以查找信息，可以网购，但是没有提到可以做家务．故选C．
49．A根据第二段原句A network is a group of computers put together．These networks joined together are called the Internet．可以得出互联网是由很多电脑组成，而不是由一个大的计算机组成．故选A．
50．B根据最后两句话But do you know 98% of the Information is in English？So what will English be like tomorrow？的描述可以推断出，在应用网络方面，英语是很重要的．故选B．

点评本文中长句较多，一时很难读懂句子含义，注意多读几遍，不要强求非得理解一词一句的含义，能把握文章大意就行．然后带着问题阅读短文，一般就能顺利找出答题依据．对于不能直接找到根据的问题注意联系上下文，根据短文中心总结出正确答案．

16．Think of life as a game in which you are playing with five balls in the air．You name them work，family，health，friends and spirit （精神） and you keep all of them in the air．You will soon understand that work is a rubber ball．If you drop it，it will bounce （弹跳） back．
But the other four balls，family，health，friends and spirit，are made of glass．If you drop one of these，they will be broken．They will never be the same．You must understand that and try to have balance in your life．How？
Don't look down on your worth by comparing yourself with others．It is because we are different and each of us is special．
Don't let other people set goals for you．Only you know what is best for yourself．
Don't give up when you still have something to give．Nothing is really over until the moment you stop trying．
Don't be afraid of difficulties．It is by taking chances that we learn how to be brave．
Don't shut love out of your life by saying it's impossible．The quickest way to receive love is to give it； the fastest way to lose love is to hold it too tightly （紧紧地）； the best way to keep love is to give it wings．
Don't run through life so fast that you forget not only where you've been，but also where you are going．
Don't be afraid to learn．Knowledge is a treasure （珍宝） you can always carry easily．
Don't use time or words carelessly．You can't get them back．Yesterday is history，tomorrow is a mystery，and today is a gift； that's why we call it"the present"．Life is not a competition，but a trip，step by step．

13．Mistakes are great teachers．Success comes to those who are willing to risk making mistakes to achieve their goals and wishes，and who are able to learn from those mistakes．And in order to learn from mistakes，you must be willing to pay for them．
Mistakes can be very valuable，but when you try to get others to pay for your mistakes，then you lose the chance to learn from them．When something goes wrong，it's usually very easy to find someone else's mistakes，but is that useful？
Much of the value of mistakes comes from the fact that they need a cost that must be paid．The person who learns the most from a mistake is the one who pays the price for that mistake．
When you made a mistake，what you shouldn't do is run away from it．You need to accept it．Pay the price，learn the lesson，and grow that much stronger．
When you make a mistake，don't look back at it long．Remember the reason for it，and then look forward．Mistakes are lessons of wisdom．The past cannot be changed．The present is still in your power．Make full use of your mistakes to achiever your goals and wishes．

Mistakes are great（51）teachers
Who can （52）succeed	Success comes to those who not only achieve their goals and wishes at the risk of making mistakes （53）but learn from and pay for them．
When you make mistakes	Don't （54）run away from them．It's easy but （55）useless to find someone else's mistakes．
The （56）value of mistakes	You can learn a lot from mistakes and grow stronger by （57）payingthe price for them．
The advice	When you make mistakes，remember （58）why you make them and then look forward because you can't change the （59）past．The present is still in your power，so make full use of them in （60）order to achieve your goals and wishes．

20．When I was four years old，I wanted nothing more in life than to play the piano．My best friend Betty had a piano．But Betty hardly played it at all．She would rather play hide-and-seek．It didn't seem fair．
One day my mother came to pick me up from Betty's house．"Watch this!"I told her．Then I ran to play a song I had learned that morning．I was so proud of what I'd learned．"That's nice，Jenny，"she said．"But we can't afford a piano．"
When I turned six，my mother bought me a recorder（直笛）．The problem was that I didn't love the recorder．When I played the recorder，I didn't feel anything special inside．I asked my mother if we could have a piano．"We still can't afford one，"she said．"One day，I promise．"
In the sixth grade，my mother traded in the recorder for a real clarinet（黑管）．I like the clarinet more，but it still wasn't a piano．It wasn't the music that was inside of me．
One day，when I was in the seventh grade，my mother cut an ad out of the newspaper．We drove to a stranger's home in Providence，Rhode Island．The woman had a beautiful，dark wood piano from Russia．It was called an upright piano because it was tall．It was so shiny that it looked like it was wet．"We'll take it，"my mother said．"It has a nice sound．"
After that，I played the piano every single day．When I left for school in the morning，I would leave the sheet music open on the piano．When I got home，I would walk straight to the piano and sit down and start playing the sheet music．I even played if I stayed home sick．I had finally found the music inside of me．
Do you struggle with music？Have you been given an instrument to play，but you just can't play it？Maybe you think you're just no good or that you don't have any musical talent．Don't get discouraged．It's not true!We all have music inside of us，even if it's just what we listen to．Now it's up to you to find the right way to set that music free．

B．An old woman sent Jenny a clarinet from Russia．
