Your computer has been playing music for years, one CD at a time. Now hundreds of songs can be stored in your PC if they' re in the MP3 format (格式).
What is it?
MP3 compressed(壓縮) music into small computer files. You may download MP3 music several ways: Music can be downloaded from websites that have turned wide music libraries into MP3. Once MP3 music is on your PC’s hard drive, you can play it through your computer's speakers, "burn" it onto blank CDs or swap(交換) MP3 files with friends using e -mail.
How much?
Software needed to play and convert MP3 music is often free. Compact portable MP3 players start at around $ 40 and can hold hundreds of songs. A blank CD on which you can record music costs about a dollar.
Advantages
MP3 turns your home PC into a jukebox(自動唱機) . Small MP3 players are the size of a deck of cards(一副牌), making it easy to take hundreds of songs with you. 
Disadvantages
You may find that some websites only allow you to listen but you can't download music. Others let you download music but can't be copied to MP3 players. And a growing number of new CDs make it impossible to copy songs to a computer.
小題1:How can you get MP3 music?
A．By turning your home PC into a jukebox.
B．By taking your own music or songs with you.

During my second year of nursing school, our teacher gave us a test. I was a hardworking student and I did well in all the subjects. I finished the questions successfully until I read the last one: “What is the first name of the woman who cleans the school?”
Of course this was a joke. I saw the cleaning woman every day. She is short and about 60 years old. She has dark hair. But how would I know her name? I had never talked with her before. In fact, I’d never even thought about talking to her. I stared at my paper and started to feel rather guilty. Finally, I handed in my paper, leaving the last question blank.
Before the class ended, one student asked if the last question would count toward our grades.
“Absolutely,” the teacher said. “In your life, you will meet many people. All are important. They deserve your attention and care, even if all you do is to smile and to say hello.”
I’ve never forgotten that lesson. Everyone deserves my attention and I should get to know all of the people who work and live around me. That was, perhaps, the most important lesson of my life. I also learned the cleaning woman’s name was Dorothy.
小題1:How was the writer at the nursing school?
A．She didn’t study hard.B．She was one of the top students.
C．She loved telling jokes. D．She often asked questions in class.
小題2:What did the cleaning lady look like?
A．She had only a little hair.B．She was not tall.
C．She looked young.D．She always smiled.
小題3:How did the writer feel she first saw the last question?
A．She felt guilty.B．She felt surprised.
C．She felt excited.D．She felt comfortable.
小題4:What can we learn from paragraph 3 and 4?
A．The last question was a part of the quiz.
B．The students needn’t answer the last question.
C．Only one student didn’t know the answer.
D．None of the students knew the woman’s name.
小題5:What did the teacher want to tell the students through the last question?
A．You should pay attention to everyone around you.
B．You should work hard to get good grades in school.
C．You should be friends with the cleaning lady.
D．You should try to make as many friends as you can.

Are you still doing the V for victory sign? It’s out. The latest popular hand gesture（手勢）is to curl both of your hands and put them together to make a heart—shape. Known as “hand heart”, many young stars in the US including Justin Bieber , Blake Lively and Taylor Swift have done the move in recent photos.
“The heart — hand gesture means something between ‘I love you’ and ‘thank you’, ”said the country singer Taylor Swift,21.”It’s a sweet, simple message which you can send without saying a word.”
Taylor Swift often puts her hands above her head in the heart shape at her concerts. And she is believed to be the first to make the gesture popular.
Last month during a charity show, Justin Bieber and his superstar friends did it to help out three kids whose parents were killed in a car accident. The gesture became a real hit after that.
“It used to take longer for nonverbal（不用語言的）culture to move. But now ,with smart phones and the Internet, it’s much faster,” said Patti Wood, an American language expert.
