Nov, 5, 2005—More and more TV shows, movies and sporting events are being broadcast in High Definition (HD) —including “Good Morning America.” If you want to join the millions who are already experiencing a superior picture, you’ll need a High Definition TV (HDTV). But even if you’re ready to retire your old TV — or move it into the back bedroom where no one will ever see it —you’re bound to have lots of questions before you make an investment in a new drool-worthy HDTV.

You might be wondering about hardware, cost and how to actually receive High Definition programming on your set. “GMA” technology contributor Becky Worley offers this primer (入門(mén)書(shū)) to understanding the complicated world of HD.

What is HDTV ①？

High definition TV is a richer transmission of television signals that makes for a more vivid viewing experience. HDTV is to standard TV what FM radio is to AM radio. HDTV is crisp , clear and noise-free, with resolution that is at least twice that of analog (模擬信號(hào))television and CD-quality sound .

How Do I Get HDTV ②?

HDTV signals are broadcast via antennas in urban areas, and via satellite TV or cable TV.

To receive an over-the air HDTV signal, you must live within a certain radius（半徑）of an HDTV broadcast antenna and have the proper HDTV tuner (調(diào)諧器) / antenna (天線) installed in your home .

To receive a Cable or Satellite HDTV signal, you must have a proprietary HDTV set-top box supplied by your provider.

Not all programming is available in HDTV yet, but many network shows and sporting events are currently in HD and many more are converting over.

When you watch a DVD on your HDTV, it is not technically HDTV quality, but it will look crisper on your HDTV than on a regular TV.

HDTV, HD-Ready TV, and EDTV

There are three major terms that will describe the high-end TV sets that are on sale today :HDTV ③ are TV sets that can receive and process over-the-air HD signals. You may need an antenna to receive the HD signal, but an HD tuner is built into the set and can process the signal without any other equipment. If you want to receive an HD signal from your cable or satellite provider, you will need one of the provider’s proprietary set-top boxes.

HD-Ready TV are TV sets that need an additional piece of hardware to actually receive the HD signal, such as a stand-alone HD tuner (from $250 and up) or the set-top HDTV box provided by your cable or satellite TV company.

EDTV stands for Enhanced Digital Television. The visual quality of an EDTV is better than a standard analog TV, but is not as crisp or bright as a true HDTV.

1．Which of the following best describe the features of HDTV?

       A．It offers more TV channels and choices of programs.

       B．It offers more interesting and entertaining programs.

       C．It offers programs with clearer pictures and sound of better quality.

       D．It offers program for high technology

2．How to understand the underlined sentence “HDTV is to standard TV what FM radio is to AM radio.” in this passage? It is       .

       A．a(chǎn)n example to show HDTV is different from common TV.

       B．a(chǎn) comparison to show HDTV is more advanced than common TV.

       C．a(chǎn)n example to show the similarity between HDTV and FM radio .

       D．a(chǎn) comparison to show HDTV is better than FM radio .

3．Does “HDTV” carry the same meaning in different places (①②③) of this article ?

       A．①and ②carry the same meaning while ③carries different meaning .

       B．①and ③carry the same meaning while ②carries different meaning .

       C．②and ③carry the same meaning while ①carries different meaning .

       D．①, ②and ③all carry the same meaning .

4．If you want to receive HDTV program at home, you should have         .

       A．a(chǎn)n antenna , an HDTV set and a tuner

       B．a(chǎn)n HD-ready TV set and live within the radius of an HDTV broadcast antenna

       C．a(chǎn)n HDTV set , an antenna and live within the radius of an HDTV broadcast antenna

       D．a(chǎn)n EDTV set and a set-top box

第三部分  閱讀理解（共20小題，；每小題2分，滿分40分）

     On Nov.18, 1995, Itzhak Perlman, the violinist, came on stage to give a concert in the Avery Fisher Hall at the Lincoln Center in New York City.

     If you have ever been to a Perlman concert, you know that getting on stage is no small achievement for him.  He was stricken with polio (小兒麻痹癥) as a child, and so he has braces (支架) on both legs and walks with the aid of a pair of crutches (拐杖).

     He walks painfully until he reaches his chair.  Then he sits down  slowly,  puts his crutches on the floor, undoes the clasps (扣壓環(huán)) on his legs, pushes one foot back and extends the other foot forward. Then he bends down and picks up the violin, puts it under his chin, nods to the conductor and begins his play.

     But this time,  something went wrong.  Just as he finished the first few notes,  one of the strings on his violin broke — it went off like gunfire across the room.      We figured that he would have to get up, put on the clasps again,  pick up the crutches and limp his way off stage — to either find another violin or else find another string for this one. But he didn't. Instead, he waited a moment, closed his eyes and then signaled the conductor to begin again.

     The orchestra began,  and he played from where he had left off. When he finished,  there was an extremely impressive silence in the room. And then people rose and cheered.  He smiled,  wiped the sweat from his brow, raised his bow to quiet us,  and then he said in a quiet tone, "You know, sometimes it is the artist's task to find out how much music you can still make with what you have left."

1. What does the author mean when he writes the underlined part in Paragraph 2?

    A. It's very difficult for Perlman to get to the stage. 

    B. It's' hard for Perlman to play a violin with three strings.

    C. It's not easy for Perlman to face such a large audience.

    D. Pefiman plays the violin with three strings successfully.

2. The third paragraph describes             .

    A. how Perlman deals with his disability

    B. Pefiman's attitude towards the concert

    C. the various stages of Perlman' s performance

    D. the difficulties Pefiman had before playing

3. What does the underlined word "one" in Paragraph 5 refer to?

    A. String.              B. Crutch.

    C. Violin.              D. Orchestra.

4. Itzhak Pefiman can be best described as a man who is         .

    A. intelligent            B. strong-willed

    C. humourous           D. highly skilled
