注重拓展。第一,从老板的“买一送一”到“我”的“传递筷子”;第二,“我”在“送筷子”后又“送蛋糕”;第三,小女孩回赠“两朵玫瑰”。前两者是第一个层面,后者是第二个层面。此文还可以锦上添花——标题改为“两朵玫瑰”。此文可变格用于“和谐”或“爱心”或“感恩”的话题作文,根据题旨,强化相关材料。 Focus on development. First, from the boss’s “buy one get one free” to “I” “transmit chopsticks”; secondly, “I” “after sending chopsticks” and “get cake” “The third, the girl rebates” two roses.“ The first two are the first level, and the latter is the second level. This article can also be icing on the cake - heading changed to ”two roses“. This text can be used for topical compositions such as ”Harmony“ or ”Love“ or ”Gratefulness". According to the topic, the relevant materials are strengthened.
