[多项选择]在中国效率最高的会议是学校召集的家长会。家长会完全符合“廉政建设”的原则，与会的家长绝不会像参加一些行业会议那样，先看看会议地点是不是设在风景旅游区，会后发不发纪念品之类，再决定是否参加。很多会议都难得准时，唯有家长会绝对正点召开。家长们个个全神贯注地倾听、记录，生怕漏一点内容。不少会议都可列入可开可不开之列，但对于学校和家长而言，家长会则是必不可少的。

参考答案:The most efficient meeting in China is the parents’ meeting organized by the school. The parents’ meeting is in full conformity to the principle of "building an honest, clean government". When it comes to some trade conferences, people tend to base their decision to participate on whether the meeting is convened in a tourist spot or whether gifts of souvenirs will be handed out after the meeting. This, however, never happens in the case of parents’ meeting. While many other meetings rarely start on time, the parents’ meeting is always punctual. At the parents’ meeting, everybody listens and takes notes attentively lest they miss a word. Unlike many other meetings, the parents’ meeting is absolutely necessary for teachers and parents.
