Taste is suc．h a subjective matter that we dori't usually conduct preference tests for food． The most you can say about anyone's preference is that it's one person's opinion．But because the two bigcola companies-Coca-Cola and Pepsi Cola-are marketed so aggressively, we've wondered how big arole taste-preference actually plays in brand loyalty．We set up a taste test that challenged people who identified themselves as either Coca-cola or Pepsi fans: Find your brand in a blind tasting．
we inwited staff wolunteers who had a strong liking for either Coca-Cola Classic or Pepsi, Diet Coke．or Diet Pepsi．These were people who thought they'd have no trouble telling their brand from the oLher brancl．
We eventuallv located 19 regular cola drinkers and 27 diet cola drinkers．Then we fed them with four unidentified samples of cola one at a time, regular colas for the one group, diet versions for the other．rOVe asked them to tell us whether each sample wa．s Coke or Pepsi; then we analyzed the records statistically to compare the participants' choices \~-ith what mere guesswork could have accom-plished．
Getting all four samples right was a tough test, biit not too tough, we thought, for people whobelieved they could recognize their brand． In the end, only 7 0ut of 19 regular cola drinkers correct-ly identified their brand of choice in all four trial．s． The diet-cola drinkers did a little worse-only 7 out of 27 identified all four samples correctly．
Both groups did better than chance would predict, but nearly half the participants in each group made the wrong choice two or more times．Two people got all'four samples vrrong． Overall, hal．f theparticipants did about as well on the last round of tasting as on the first, so tiredness, or taste burn-out, was not a factor． Our preference test results suggest that only a few Pepsi participants and Coke fans may really be able to tell their favorite brand by taste and price．

Recently a Beijing father sent in a question at an Interact forum(論壇)asking what“PK”meant．
“My family has been watching the‘Super Girl’singing competition TV programme．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“Super Girl”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 ranking．
Like this father，Chinese teachers at high schools have also been finding their students’compositions using Internet jargons which are difficult to understand．A high school teacher from Tianjin asked her students to write 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”refers to Piao Liang Mei Mei(beautiful girl)．“FB”means Fu Bai(corruption)．“KPM”is short for KF．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，referring to an ugly looking female)ora Qing wa(frog，referring to an ugly looking male)is，you will possibly be regarded as a CaiNiao!

Recently a Beijing father sent in a question at an Internet forum (論壇) asking what "PK" meant. "My family has been watching the 'Super Girl' 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 "Super Girl" 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 ranking.
Like this father, Chinese teachers at high schools have also been finding their students' compositions using Internet jargons (行話) which are difficult to understand. A high school teacher from Tianjin asked her students to write 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" refers to Piao Liang Mei Mei (beautiful girl). "FB" means Fu Bai (corruption). "KPM" is short for KFC, Pizza Hut and McDonald's.
