参考答案及解析
1. A 句意：——不要在这儿吸烟，爸爸。在公共场所不允许吸烟。——哦，对不起，我马上停止。“不允许吸烟”，吸烟smoking在句中作主语，用被动语态。动名词短语smoking作主语，谓语用三人称单数。故选A。
2. A 句意：——你的车真干净！——谢谢。它经常被洗。is washed被动语态，被冲洗；washes第三人称单数形式；was washed一般过去时的被动语态；washed过去式。根据句意可知，这句话说的是经常性的动作，因此应该用一般现在时态，并且It和wash之间构成被动关系，故应选A。
3. A 句意：今天很多人读这本小说。根据today可知此处用一般现在时，根据介词短语by many people可知此处用被动语态。主语the novel是单数形式，故谓语用单数形式。句子的主语novel 与read之间是被动关系，故用is read。故选A。
4. D 句意：每年这儿周围种植很多树，现在我们就能够享受更新鲜的空气了，主语是trees是谓语plant的承受者，用被动语态，动词用过去分词：planted；由句中关键词every year可知本题用一般现在时态，所以选D。
5. B 句意：——克劳迪娅，周六你去参加杰夫的生日宴会吗？——除非我收到邀请。结合语境可知下文省略了主句，当主句描述将来发生的动作时，条件状语从句中用一般现在时表示将来动作。从句主语是动作对象，故用被动语态，选B。
