First, let's talk about culture．The difference between the mobile phone and its parent，the fixed-line phone is，you get whoever answers it This has several implications．The most common one，however，and perhaps the thing that has changed our culture forever，is the “meeting” influence．People no longer need to made firm plans about when and where to meet．Twenty years ago，a Friday night would need to be arranged in advance．Now，however．a night out can be arranged on the run．Texting changes people as well．In theft paper "Insights into the Social and Psychological Effects of SMS Text Messaging"，two British researchers distinguished between two types of mobile phone users：the “talkers” and the "texters"—those who prefer voice to text message and those who prefer text to voice．They found that the mobile phone's individuality and privacy gave texters the ability to express a whole Flew outer personality．Texters were likely to report that their family would be surprised if they were to read their texts．
Another scientist wrote of the changes that mobiles have brought to body language．There are two kinds that people use while speaking on the phone．There is the "speakeasy"：the head is held high，in a self-confident way，chatting away．And them is the "spacemaker"：these people focus on themselves and keep out other people．

听力原文： The world's smartest adolescents in mathematics and science are in Singapore, according to a global survey of educational achievement. In the 3rd International Mathematics and Science Study, 13-year-olds from Singapore achieved the-best scores in standardized tests of math and science that were administered to 287,896 students in 41 countries in 1994 and 1995. The survey suggests that science and math education is especially strong in the Far East, while well behind those top scores, students from Australia earned higher marks in math than their counterparts in England, who in turn did better than American students. The study collected information on the students' teachers and homes. Not surprisingly, the highest-scoring students had well-educated parents or came from homes containing studying aids such as computers, dictionaries or even such elemental facilities as desks. The study shows that boys generally did better than girls in science, but there was little difference between them in math. Boys scored better than girls in physics and chemistry. There were no sex differences in the life and environmental sciences. In addition to being tested, students in the project were asked how proficient they thought they were in math and science. Students in some countries, such as Columbia and Kuwait, had an overly optimistic view of their skills. Meanwhile, some of the best students from Japan and Korea, for example, were needlessly pessimistic even though they did far better in math than almost all of the other students.
