题目列表(包括答案和解析)
The strong fear of high school math is lost here among the blue light of computer screens and the sounds of typing keyboard．
A fanfare （喇叭声） plays from a speaker as a student passes a chapter test．Nearby another student is watching a video lecture．Another works out a math problem in her notebook before clicking on a multiple-choice answer on her screen．
Their teacher at Agoura High School, US, Russell Stephans, sits at the back of the room, watching as scores pop up in real time on his computer grade sheet．One student has passed a level, the data shows; another is retaking a quiz．
"Whoever thought this up makes life so much easier," Stephans says．
This textbook-free classroom is by no means the norm（常态）, but it may be someday．Slowly, but in increasing numbers, schools across the US are replacing the heavy and expensive textbook with its lighter and cheaper cousin: the digital textbook．
A digital textbook can be downloaded, projected and printed, and can range from simple text to a course filled with multimedia and links to Internet content．Some versions （版本） must be purchased; others are "open source" —free and available online to anyone．
Some praise the technology as a way to save schools' money, replace outdated books and better engage students．Others say most schools don't have the resources to join in, or they question the quality of open-source content．
Paper books still hold the highest percentage of the US textbook market, with digital textbooks making up less than 5 percent, according to analyst Kathy Mickey of Simba Information, a market research group．
But that is changing, as grade schools follow the lead of US universities and schools in other countries, including South Korea and Turkey．
California made the largest embrace （拥抱） of digital textbooks this summer when it approved 10 free high school math and science titles developed by college professors．The state left the choice to use them up to individual schools．
"The textbooks are outdated, as far as I'm concerned, and there's no reason why our schools should have our students pull around these old-fashioned and heavy and expensive books," Governor Arnold Schwarzenegger said this summer．
But some disagree with the idea that digital textbooks will improve education quality．
"Keep in mind that with open-source materials, you have to ask: 'Where are they coming from?'" said Jay Diskey, executive director of the Association of American Publishers' school division．"Is it a trusted source? Is it based on real research?"
Diskey said traditional textbooks offer a comprehensive course, while some open-source texts provide only bits and pieces．"There can be quite a difference of content and accuracy," he said．"In many cases, you get what you pay for．"

The first MP4 player was born years ago. Soon many music fans were wondering how fantastic it is! If you have been into technology enough, perhaps you may have a knowledge of the MP4. If not, you do need to know something before buying one, even if you are familiar with MP3. MP3 is the CD-like disc with greater capacity. How about MP4? This small digital product will really enrich the joy from listening to music. You can even feel the “touch” of music to your soul!
Now, some similar digital products advertised as “MP4 player” are simply MP3 players, which do not play video and MPEG format and also lack other particular functions. These products confuse some buyers, as they may think the “MP4” players simply mean they can do more than MP3.
What is MP4?
It is a multimedia container. It is not only used to store digital audio and digital video streams, especially those of MPEG, but can also be used to store other data such as subtitles and pictures. As a most modern container format, it allows streaming over the Internet.
With the help of a piece of MP4 video equipment, you can change various programs such as MPEG to MP4, ASX to MP4, AVI to MP4 and so on, which can be done very quickly and easily without any effect on the sound quality. By installing DVD-MP4 software, you can transfer particular music from a DVD to an MP4 video file. It really excites your listening music experience.
Then, there is MP4 advanced and you can set your own collection of all the programs—TV shows, games, and music. You can even see movies which are still running in cinema. What else digital product could you possibly ask for?
It is suggested here that you should ______ before buying an MP4 player.
A. first be a music fan B. have a knowledge of MP4
C. get familiar with MP3 D. buy a CD-like disc
From the passage, we can see that MP4 is ______ MP3.
A. much bigger than B. just as advanced as
C. not so particular as D. more functional than
Which function of MP4 is NOT directly mentioned in this passage?
Storing digital audio and video streams.
Recording some movies in cinema.
Playing TV shows, games and movies.
Transferring particular music from a DVD.
From the last sentence, it’s clear that the writer tries to tell us it is ______.
reasonable to buy other digital products
impossible to buy something else
a very wise choice to buy an MP4
an exciting experience to buy an MP3
