Nixon arrived shortly before 7 p.m. as buoyant and good-humoured as reporters had ever seen him.?1. 划线部分为形容词短语，作 arrived 的“方式状语或伴随状语”，也可以表示 arrived 时与主语有关的状语。2. as reporters had ever seen him 是“比较从句”。不过，我觉得里面有个错误：漏掉了一个连词 when。改为：as buoyant and good-humoured as when reporters had ever seen him.?3.?shortly before 7 p.m. 这个词组，shortly 等于 soon 之意，修饰?before 7 p.m., 网友应该知道这个短语：soon after?7 p.m. ?要学会举一反三：soon before 7 p.m.shortly after 7 p.m.?shortly before 7 p.m.4. 你为何要自己造个句子，去解释一个不难理解的句子呢？?man of himself of all times 是啥意思？
