Meng Meihui,14,from Dongying, Shandong, loved reading certain pieces of work. But she paid particular attention to her classmate’s every composition, just to find her faults. “Everyone said she was better at writing than me. I didn’t believe it. I wanted to beat her,”Meng said. Meng was caught by the green-eyed monster-jealousy(嫉妒) Jealousy is _____among students. Most people may feel a little bit unhappy when others are better than them. It’s natural. However, if students don’t change theirs mindset(思维方式)and deal with it well, jealousy can bring out many problems. Su Lulu, 14, from Xiamen, Fujian， said those who are too jealous of others might lose _____easily.“Few people like those who always try to find faults in others,” Su said. “A popular student should be open-minded.” Besides affecting students’ interpersonal(人际间的)relationships, jealousy may also limit students’ development. Meng said that during that time, she paid too much attention to her competitor(竞争者)and_______to improve herself. “It was tiring and useless,” she said. Luckily, Meng_____ realized the problem. She stopped her silly behavior and focused on her own progress. Wang Xiao, a psychology(心理学)teacher at Huangshi Foreign Language School, Hubei, agreed with Meng’s practice. Wang said the best way to deal with jealousy is to turn it into motivation(动力) “___those who are better than you and focus on yourself, ” Wang said. “It’s more important to improve yourself than to be better than others.” Wang also suggested that students be confident about themselves. “Everyone has their advantages and disadvantages. Don’t _______your disadvantages with others’ advantages,” he said.
