如何在PDF文件中停下来的地方进行阅读
By default, when you open PDF files in most PDF readers, they open to the beginning of the file, even if you were on a different page the last time you had the file open.
默认情况下，当您在大多数PDF阅读器中打开PDF文件时，即使您上次打开文件时在另一个页面上，它们也会打开到文件的开头。
That’s very inconvenient if you want (or need) to close the PDF reader when you’re not done reading the PDF file. What if you need to reboot or shut down your PC? We’ll show you how to set up the best PDF readers in Windows to open PDF files to where you left off.
如果您想(或需要)在未阅读完PDF文件时关闭PDF阅读器，这将非常不便。 如果需要重新启动或关闭PC怎么办？ 我们将向您展示如何在Windows中设置最佳的PDF阅读器，以将PDF文件打开到您停止的地方。
(Sadly, this option is not available in Google Chrome, Mozilla Firefox, or Microsoft Edge when it comes to PDF files—you’ll have to manually go to where you left off. Because these browsers only contain very basic PDF readers, they don’t have a setting that allows the browser to remember where you left off in a PDF file. You’ll need a dedicated PDF reader to do this.)
(遗憾的是，当涉及到PDF文件时，此选项在Google Chrome ， Mozilla Firefox或Microsoft Edge中不可用-您必须手动转到上次停止的位置。因为这些浏览器仅包含非常基本的PDF阅读器，所以它们没有没有允许浏览器记住您在PDF文件中保留的位置的设置。您需要专用的PDF阅读器来执行此操作。)
苏门答腊岛PDF (Sumatra PDF)
Sumatra PDF comes in an installable version and a portable version. Both versions are capable of opening a PDF file to where you left off. This setting seems to be on by default in both versions, but we’ll show you where it is in case you accidentally turned it off. Open Sumatra PDF and click the menu button in the upper-left corner of the window. It doesn’t matter whether you have a PDF file currently open or not.
Sumatra PDF有可安装版本和便携式版本。 两种版本都可以将PDF文件打开到上次停止的位置。 在两个版本中，该设置似乎默认都处于启用状态，但是我们将向您显示该设置在哪里，以防您不小心将其关闭。 打开Sumatra PDF，然后单击窗口左上角的菜单按钮。 是否打开了PDF文件都没有关系。
Go to Settings > Options.
转到设置>选项。
On the Sumatra PDF Options dialog box, make sure the “Remember opened files” box is checked, if you want Sumatra PDF to remember where you left off in PDF files. Then, click “OK”.
如果您想让Sumatra PDF记住您在PDF文件中保留的位置，请在Sumatra PDF选项对话框中，确保选中“记住已打开的文件”复选框。 然后，单击“确定”。
The Remember opened files setting also allows you to access recently opened files on the Frequently Read screen which displays when there are no files open. Simply click on a file’s icon to open that file. The file will open to the same location you were on when you last closed the file. If the Remember opened files option is off, you must open files from the main menu and all PDF files will open to the beginning.
“记住已打开的文件”设置还允许您在“经常读取”屏幕上访问最近打开的文件，该屏幕在没有文件打开时显示。 只需单击文件图标即可打开该文件。 文件将打开到上次关闭文件时所在的位置。 如果“记住打开的文件”选项处于关闭状态，则必须从主菜单中打开文件，所有PDF文件都将以开头开头。
Adobe Acrobat Reader DC (Adobe Acrobat Reader DC)
To have Adobe Acrobat Reader DC remember where you left off in PDF files, open the program and go to Edit > Preferences. It doesn’t matter whether or not you have a PDF file open.
要使Adobe Acrobat Reader DC记住您在PDF文件中保留的位置，请打开程序并转到“编辑”>“首选项”。 是否打开PDF文件都没有关系。
On the Preferences dialog box, click on “Documents” in the Categories list. Then, check the “Restore last view settings when reopening documents” box.
在“首选项”对话框中，单击“类别”列表中的“文档”。 然后，选中“重新打开文档时还原最后的视图设置”框。
Click “OK” to accept the change and close the Preferences dialog box.
单击“确定”接受更改，然后关闭“首选项”对话框。
Now, when you reopen a PDF file, Acrobat Reader will go to the page you were on when you last closed the file.
现在，当您重新打开PDF文件时，Acrobat Reader将转到您上次关闭该文件时所在的页面。
