　 Facebook is helping to save the environment. So is your iPhone. Surprised? I was too when I first realized it but after I thought about it for a while, I totally believed it was true.

　 Let’s start with your iPhone or other smart phones for that matter. How is that helping the environment? Think about it. Before, you used to have your phone, your camera, your mp3 player and your DS or PSP. Those are four electronic items. Each of these needs charging. Each of these came in its own packaging. Each of them was shipped individually from where they were made and each was likely picked up by you in separate trips. That’s four times the carbon emission per product. By simply buying an iPhone you have cut down your carbon emission by three quarters.

　 That’s not all. The digital content distribution provided by iTunes Store allows us to buy music electronically. This means there is no CD, no manufacturing carbon footprint, and no shipping carbon footprint. The eBooks stores mean that we no longer have to ship books all over the world. Let’s face it. Books are heavy and take up a lot of space (compared to a CD anyway). There’s a lot of carbon involved in making and shipping them. Even though the wood to make the paper usually comes from sustainable sources, the reduction in carbon is significant. Downloading apps mean that you save on all the games packaging and harmful chemicals involved in the production of all of the CDs and manuals. Another winner.

　 Facebook is another example of where physical products are being converted into digital products. It is easy to upload hundreds and thousands of copies onto Facebook and have everyone cheek them out. To do this before you’d have to print hundreds of copies and send them physically to people. Granted, you might not want to send all your photos around but digital cameras and Facebook allow the photographers and the viewers to make decisions about which photos are worth keeping and which are not.

63. What do we know about iPhone from the second paragraph?

　 A. It is multi-functional.

　 B. It contains four electronic items.

　 C. It has no carbon emission.

　 D. It doesn’t need packaging.

64. IPhone can help to save the environment because __________.

　 A. it is easy to carry

　 B. it needs to recharge

　 C. it cuts down carbon emission greatly

　 D. it is made of wood

65. ITunes Store probably can help us to ___________.

　 A. listen to music of high quality

　 B. download music from the Internet

　 C. make music by ourselves

　 D. enjoy free music from the Internet

66. We learn from the last paragraph that Facebook allows us to ____________.

　 A. send photos to friends physically

　 B. send photos around more quickly

C. print photos freely

D. upload digital photos

　　IS IT TIME TO GET MP3?

　　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 compresses（压缩）music into small computer-friendly files. You access MP3 music several ways: Tunes can be downloaded from websites that have converted（转变）vast music libraries into MP3. Or you can prerecorded CDs into your PC and convert songs in minutes 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（交换）MP3 files with friends using e-mail.

　　How much?

　　Software needed to play and convert MP3 music is often free. It comes preinstalled（预先安装）on most new computers or can be downloaded from many websites, including MP3. com. Some MP3 sites are free. Just type “MP3 sites” into any search engine. Compact portable MP3 players start at around $ 50 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（自动唱机）. Tiny MP3 players are the size of a deck（一副）of cards, making it easy to take hundreds of songs with you.

　　Disadvantages

　　You may find that music at many sites is limited. And some only allow you to listen rather than download offerings. Others let you download music that then can’t be copied to MP3 players. And a growing number of new CDs make it impossible to copy songs to a computer.

　　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.

　　C．By copying songs to a PC through the speakers.

　　D．By downloading from websites which have converted music libraries into MP3.

　　2．Which is NOT true to the passage?

　　A．Software needed to play and convert MP3 music is often free of charge.

　　B．MP3 music can be “burned” onto blank CDs or swapped with friends by e-mail.

　　C．MP3 music can be taken along while traveling.

　　D．A greater number of new CDs make it possible to copy songs to a computer.

　　3．How much will you pay for a MP3 player?

　　A．Free of charge.

　　B．Free downloading.

　　C．At least fifty dollars.

　　D．About a dollar.

　　4．What is the closest meaning of the underlined word “burn”?

　　A．Copy.
