       Three kids have been learning chemistry for only a few months. But they have already begun to
challenge a world famous scientist!
       Li Weichi, Huang Runling, and Xiao Yan are from Zhongshan Huaqiao Middle School in Guangdong. They have just found a red cabbage that could be a new kind of acid-base indicator (酸碱指示剂). They want it to take the place of litmus (石蕊) paper.
       "We've learnt to think of and ask questions about life by ourselves," said Li, "We work well with each other."
       British scientist Robert Boyle discovered the use of litmus paper over 300 years ago. Now it is used widely in experiments all over the world.
       But when the kids did some experiments in class last winter, they saw that the litmus paper didn't turn very blue with base matter. It's hard to get a clear result.
       Will there be a better indicator than litmus paper? The three kids decided to try and find out!
       How? They went to collect over 40 plants in parks, gardens and markets. Then they ground (研磨)
leaves, flowers and stems (茎) to get the pigments (色素) from them.
       The kids mixed pigments with acid and base. They spent months watching carefully to see which
paper showed the best colour change. They decided it was the litmus paper!
       "It's our first scientific journey, Huang said, "But it makes me want to try harder."

　　My summer hols wr CWOT．B4, we usd 2 go 2 NY 2C my bro, his GF ＆ thr 3 ：-@ kids FTF．ILNY; its gr8．

　　Can you understand this sentence? If you can't, don't feel too bad．The middle school teacher in England who received this as homework couldn't either．This is Netspeak：the language of computerized(电脑化的)communication found on Internet or mobile phones．To newcomers, it can look like a completely foreign language．So, what is the "translation" of the sentence above? My summer holidays were a complete waste of time．Before, we used to go to New York to see my brother, his girlfriend, and their three screaming kids face to face．I love New York; it's great．

　　Schoolteachers and parents say this new form of writing is harming the English language．Increasing spelling and grammatical mistakes can be seen in students' writing．They fear the language could become corrupted(面目全非的)．

　　Everyone should just relax, say linguists(语言学家)．They believe Netspeak is in fact more of a good thing．David Crystal, from the University of Wales, argues that Netspeak and Internet create a new language use and the almost lost art of diary writing has been picked up again．Geoffrey Nunberg, from Stanford University, agrees．"People get better at writing by writing, " he says, “Kids who are now doing text messaging and e-mail will write at least as well as, and possibly better than, their parents．"

　　Linguist James Milroy says, for centuries, it is believed without exception(例外)that young people are harming the language．And you can bet your bottom dollar that when today's teenagers become tomorrow's parents, they too will think this way．Milroy argues that languages do not and cannot become “corrupted”, and that they simply change to meet the new needs．

　　However, Netspeakers do agree that it is important to teach young people how to speak and write Standard English．Cynthia Mcvey says, "I can understand Netspeak worries teachers and it's important that they get across to(沟通)their pupils that text messaging is for fun, but that learning to write proper English is a must for their future．”

　　Perhaps we should give teenagers a little more trust anyway．Erin, age 12, says, "I wouldn't use text language in my homework．Texting is just for fun．"
