注意: 派生法的规则不代表每个单词都可以用相同的前缀或者后缀进行语义 功能及语法功能的改变
派生法在语篇中的运用
1. Every college discussion about community values, social climate and behavior should include recognition of the developmental importance of student autonomy and self-regulation, of the necessary tension between safety and self-discovery.
Some people believe that the Internet has many negative aspects. Talking to people online or having a friendship with someone you only talk to on the Internet isn’t a replacement for real-life communication. While it can connect you with other people who use a smartphone, face-to-face contact with others is important to help you maintain healthy relationships.
合成法实践
