1、Suddenly he remembered that time in Rome,a year after they were married;those june nights and the fireflies.
忽然，他想起了他们结婚一年后在罗马的那段时光，那是6月的夜晚和萤火虫。
我的第一个问题：a year after.我查了 朗文字典，说这里的after是介词有如此的使用方法。好假如成立请问介词宾语是什么呢？they were married一定不是，由于that引导的名词性从句做介词补充成分，介词只有6个分别是in、besides、beyond、but、expect、save，并没after。
2、Things such as these are the best themes.
我的第二个问题：这里的“such as”是诸如、此类的意思吗？若是，那样such as“诸如、此类”后面结句子的话可否有权威例句？
1、Suddenly he remembered that time in Rome,a year after they were married;those june nights and the fireflies.
忽然，他想起了他们结婚一年后在罗马度过的那段时光，那些6月的夜晚，还有萤火虫。
remembered后接三个名词词组作宾语：that time, those June nights and the fireflies. 其中第一个宾语that time后接二个定语，in Rome和 a year after they were married.
after在此为连词，而不是介词（又接主谓结构如何能是介词？）。a year修饰after，使时间明确化。after引导的从句可以修饰名词，作后置定语，这在阅读中是常常会遇见的。语法书极少有介绍after/before从句修饰名词作定语这种现象的。这是语法书的疏漏。
2、Things such asthese are the best themes. 诸这样类的事情是最好的主题。
such as 后接的是these，而不是句子。things such as these（诸这样类的事情）作主语，are the best themes为系表结构。
