Can you tell me why this tool is different ________ that one?

[　　]

Recently a Beijing father sent in a question at an Internet forum(论坛) asking what “PK” meant.
“My family has been watching the ‘I Am the Singer’ singing competition TV program. My little daughter asked me what ‘PK’ meant, but I had no idea,” explained the puzzled father.
To a lot of Chinese young people who have been playing games online, it is impossible not to know this term. In such Internet games, “PK” is short for “Player Kill”, in which two players fight until one ends the life of the other.
In the case of the “I Am the Singer” singing competition, “PK” was used to refer to the stage where two singers have to compete with each other for only one chance to go up in competition raking.
Like this father, Chinese teachers at Middle schools have also been finding their students using Internet jargons which are difficult to understand. A teacher from Tianjin asked her students to write the compositions with simple language, but they came up with a lot of Internet jargons that she didn’t understand.
“My ‘GG’ came back this summer from college. He told me I’ve grown up to be a ‘PLMM’. I loved to ‘FB’ with him together; he always took me to the ‘KPM’,” went one composition.
“GG” means Ge Ge (Chinese pinyin for brother). “PLMM” is Piao Liang Mei Mei (beautiful girl). “FB” means Fu Bai (corruption). “KPM” is short for KFC, Pizza Hut and McDonald’s.
Some specialists welcome Internet jargons as a new development in language. If you do not even know what a Kong Long (dinosaur, meaning an ugly looking female) or a Qing Wa (frog, meaning an ugly looking male ) is, you will possibly be regarded as a Cai Niao!

When students and parents are asked to grade subjects according to their importance, the arts are usually at the bottom of the list. Music is nice, people seem to say, but not important. Too often it is only viewed as entertainment, but certainly not an education priority（优先）. This view is shortsighted. In fact, music education is very important for all students.

Music tells us who we are. Because music is an expression of the beings who create it, it shows their thinking and values, as well as the social environment it came from. Rock music represents a lifestyle just as surely as does a Schubert song. The jazz influence that George Gershwin and other musicians introduced into their music is obviously American because it came from American musical traditions. Music expresses our character and values. It gives us identity（身份，特性）as a society.

Music provides a kind of perception（感知）that cannot be acquired any other way. Science can explain how the sun rises and sets. The arts can express the emotive（情感的）meaning of the same thing. We need every possible way to discover and respond to our world for one simple but powerful reason: No one way can get it all.

The arts are forms of thought as powerful in what they communicate as mathematical and scientific symbols. They are ways we human beings “talk” to each other. They are the language through which we express our fears, our hungers, our discoveries, our hopes. The arts are ways we give form to our ideas and imagination so that they can be shared with others. When we do not give children an important way of expressing themselves such as music, we take away from them the meanings that music expresses.

Science and technology do not tell us what it means to be human. The arts do. Music is an important way we express human suffering, celebration, the value of peace and love.

So music education is far more necessary than people seem to realize.
