A lecturer at Xidian University in Xi’ an, Shaanxi province, has called on students (22) in her female-only class to sign a pledge that they will not have sex before marriage. According to a student who took the optional course, only two students signed the card. The student, who didn’t want to be named, was not comfortable saying whether she signed the promise.
    (23)" The course was mainly about how to establish healthy concepts of relationships and marriage," she said. "It was open only to female students." She said the guarantee also included a promise that the students would not have extramarital sexual relations.
    The lecturer didn’ t force anyone to sign. However, many students still disliked being faced with such a promise. Nevertheless, (24)parents showed their understanding of the school and the teacher.
    Wang Changshou, head of the Shaanxi Academy of Social Sciences, said it is necessary to strengthen moral education surrounding marriage, but (25)it is not appropriate to ask students to sign a promise. He said it is not fair to only open the class for female students because relationships and marriage involve two people. Male students should also be educated, he said. "It is an obsolete concept to curtail only women’s behavior, but not men’ s," he said.
