This study is conducted through social observation and qualitative research approaches. The scope of this study focuses on the investigation in Taipei and Shanghai. The subjects of this research will be the junior high school students in Taipei and the junior high school students in Shanghai, and the graduated or elder students, and the students' teachers and parents as well. After the research, there are some findings. The overpopulated pressure lead students in China must study harder to enter top prestigious universities. The interviewers in this study revealed that Taiwanese students do not totally study due to external stress and English learning is based on interests. Parents in Taiwan hope their kids not only learn English for good grades but also develop their interests in English learning. In Shanghai, parents urge their children to study all the time. Parents concern the school grades very much. In Taipei, teachers are willing to be students’ friends. Differently, teachers in Shanghai are more authoritative than in Taipei. Teachers emphasize the accuracy on English learning. China’s accession to WTO affects the model of English learning. Globalization accelerates the trend to learn English. These years China runs some world-class convention and exhibition which attract more international business and tourists and encourage Chinese to learn English. In the process in this study, we found the English learning motivation of students in Shanghai is stronger than Taiwan's students.
