1,一个主句+从句的定语从句.这句话说道platform,作者意犹未尽,想继续说下去.后句话是想对platform（平台）进行进一步描述,为了提醒听话者,当然使用where.what不可引导定语从句,which不可提醒地点,除非用in which.when只用于提醒对前面某段时间的进一步描述.
2,这道题从语法意义上讲,A 和 C 都可以.但这题应从说话者语气来判断,这个句子表达的重心到底是前面还是后面.注意time and again,强调“我已再三告诉过你...”,语气明显是不情愿的埋怨对方不长记性.从这点,我们可以判断,说话人不是为了强调“应严格遵守规定“,而是强调 “我再三警告过你”.那么最后反问的对象当然要按主句来：“我不是没告诉过你吧?（haven't )”.

platform 台；站台；平台

30题中的people can express their thoughts, show their daily life and communicate with each other by sending post是定语从句修饰前面的platform，而完整的句子应该是people can express their thoughts, show their daily life and communicate with each other by sending post on the platform, 因platform在该句中做的是地点状语，故选C
31题中that these rules should be strictly followed是宾语从句，作told的宾语，结构是told sb sth, 反义疑问句的助动词是根据主句谓语来的，主句谓语是have+done的形式，且是肯定的，后面应该是否定的形式，故应选A

30题的考点是宾语从句， 横线后面的一整个句子很明显是 修饰 platform的， platform 有平台之意，我个人的理解是属地点的，因此该用连接副词where来将两个句子连接起来，所以答案就是C了。
31题的考点是反意疑问句，因为主语是第一人称且前面是肯定和一般现在时，所以最后用的语态必须也是一般现在时、否定+第一人称，因此，应该是选A的。

下面那位已经解释的很清楚了，不知你明白没，我用通俗易懂点给你说说，30是platform是个地点词语，而由整句话看来people后面的句子可以成为独立的句子，所以判断出该句话是由where引导的定语从句。31.反义疑问句，有前面的have，可以推导后面的反义，所以可以排除C/D，再由主句意思，可以推导出主语是I...
