注意:每空格1个单词。

     A mother, surnamed Wang, wondered why her daughter's junior middle school had not held a parents'

meeting over the course of two terms, so she phoned the school. The teacher told her the school had been

meeting with parents every month.

     Faced with her mother's discovery, the daughter, Ping Ping, a 13-year-old Grade-One middle school

student, admitted (承认) that she had hired the aunt of a classmate to play the role of her mother. She paid

the woman 50 yuan per meeting.

     Wang was very angry and slapped her daughter in the face.

     However, the girl appeared not to feel guilty (内疚) and stood her ground.

     "It is not my fault. Your bad behavior and dress style made me lose face," she said.

     Ping Ping complained that as far back as primary school, her mother had attended the parents' meeting

in the same black and white suit and acted as what the daughter described.

     When teachers invited parents to say a few words at the meeting, Wang often spoke with a very strong

local dialect (方言) while the other parents spoke fluent Mandarin and made brief speeches.

     Fearing that her mother would become a laughing stock (笑柄), Ping Ping decided to prevent her from

coming to parents' meeting.

     She hired her classmate's aunt to attend the parents' meeting in her mother's place.

     Mrs. Zhang, a psychologist, said it was common for young people to feel that other people's parents

were more attractive and educated than their own. The incident helps make people realize misunderstanding

can occur between parents and young children when they do not talk to one another. 

     "Teachers should help students understand the hardships parents face and organize more group activities

for parents and children," Zhang said. 

    "Parents also need to communicate with their children regularly and try to behave themselves to become

role models.
