自古以来,人们都把老师比作辛勤劳作的园丁,把学生比作祖国的花朵。我以前一直不理解人们为什么这么说,但是自从经历了一次终身难忘的实践之后,我明白了这个道理。 Since ancient times, people have compared teachers to hardworking gardeners and students to the flowers of their motherland. I've never understood why people say that before, but I've come to understand that since I've lived through a lifetime of unforgettable practices.
