First of all, globalization counts much for this phenomenon. In modern society, information in most media, be it the Internet or newspaper, is conveyed in English. As a saying goes, one can go to every corner of the world without any difficulty in communicating with local people. Unfortunately, while we emphasize the importance of English, we underrate the value of Chinese though China has been developing at an amazing speed.
But neglecting the study of Chinese is extremely harmful if the situation is left unfettered. The major harm is that China's traditional value is likely to get lost because language and ideas are interlocked in most cases. For example, when interviewed, most youngsters show that they are quite unfamiliar with some famous figures and their sayings.
To sum up, many reasons are responsible for the phenomenon and it will do us harm if we leave the situation as it is. Faced with the problem, we are expected to take effective measures. For one thing, the government should work out rules to ensure the time for the study of Chinese in school. Only in this way, can we find a cure for the problem.
