That is the theory put forth in "Amelia Earhart: The Lost Evidence," a two-hour documentary airing Sunday at 9 p.m. EDT on the History channel. It uncovers records, including this newly revealed photograph that shows what may be a healthy Earhart along with her navigator Fred Noonan, after they were last heard from.
The film also argues that after the pair crash-landed in the Japanese-held Marshall Islands, they were picked up by the Japanese military and that Earhart, perhaps presumed to be a U.S. spy, was held prisoner.That is the theory put forth in "Amelia Earhart: The Lost Evidence," a two-hour documentary airing Sunday at 9 p.m. EDT on the History channel.

编译我的文件后，结果是：

我的期望是：

Answer 1

您的问题是，第二个标题/摘要放在 中\parbox，而\parbox不能跨多页。因此，整个第二个标题/摘要被移到第二页，因为它无法放在第一页上。因此，解决方案是不使用\parbox。

您可以使用{\setlength\parindent{0pt} ... }来局部设置\parindent，或者\noindent在段落开头添加 来禁用缩进。在 LyX 中，您也可以右键单击段落并使用段落设置。

在下面的代码中，我将代码缩减到最少，这使得跟踪发生的情况变得更容易。
