Does technology influence the purity of Chinese language? Yes!
Many Chinese use messenger tools such as MSN or QQ, listen to music on MP3 players and blog on the Internet using ADSL ,but most people don’t know the Chinese meanings of the abbreviations, as many English letters have become part of the local lexicon（专门词汇）. some parents are so crazy about English letters that a couple tried to name their baby "@", they say the character used in email addresses reflects their love for the child.
While the "@" is obviously familiar to Chinese e-mail users, they often use the English word "at" to pronounce it , which sounds like ai ta, or "love him", to Putonghua speakers.
“Nowadays, more and more English abbreviations are being used in Chinese, making them an important part of the modern language," said Hou Min, a professor at Communication University of China.

The weather can influence(影响)intelligence(智力). For example, in a 1983 report by scientists, IQ of a group of students was very high when a very strong wind came, but after the strong wind, their IQ was 10% lower. The wind can help people have more intelligence. Very hot weather, on the other hand, can make it lower. Students in many schools of the United States often get worse on exams in the hot months of the year(July and August).
Weather also has a strong influence on people’s feelings. Winter may be a bad time for thin people. They usually feel cold during these months. They might feel unhappy during cold weather. But fat people may have a hard time in hot weather. At about 18 °C, people become stronger.
Lower air pressure may make people forgetful. People leave more bags on buses and in shops on low-pressure days. People feel best at a temperature of about 18 °C.
