     In the Harry Potter films, Hermione Granger is better than her male friends and is considered the brightest

pupil in her grade. Isn't it often the same in schools of our real world?

     "It's surprising but true that most of the top students have been girls since primary school. Girls are class

leaders, club presidents and the top ones in exams," said Wang Feixuan, 15, who studies at a Chengdu school.

By any measure, Wang herself is a high-achiever. She is a top student, a team leader in her school's sports club

and a winner in national English and IT competitions.

     But why do so many girls outperform their male peers?

     In Sun Yunxiao's latest book Save Our Boys, he points out that the education system is"more suited to

girls, who are good at memorizing and like to sit quietly and read." Yet he also says that girls have to do so

much more when they compete with males for honors, top universities and later good jobs. They can feel great

pressure nearly every day.

     This seems to be the same in most countries in the world. Young women in the United States are also

reported to feel the same pressure to be perfect.

     "Let's look at what we ask of our teenage girls," says Professor Stephen Hinshaw in an interview. He thinks

that it's no longer enough that a girl does well in school and is a caring friend. On the TV, on the Internet and

everywhere, girls see images of impossible perfection.

     Today's young women must be good learners, good athletes, and fill their after-school lives with other

activities. But they are also asked to have the styles and looks of popular stars."Be pretty, sweet and nice. Be

athletic, competitive and get straight. Be impossibly perfect." Stephen Hinshaw sums up.
