2. 直接按快捷键Alt + F11打开VBA编辑器，选择菜单“插入->模块”

3. 粘贴下面的代码（没有错误，已验证）

Option Explicit Sub SplitEveryFivePagesAsDocuments() Dim oSrcDoc As Document, oNewDoc As Document Dim strSrcName As String, strNewName As String Dim oRange As Range Dim nIndex As Integer, nSubIndex As Integer, nTotalPages As Integer, nBound As Integer Dim fso As Object Const nSteps = 110 ' 修改这里控制每隔几页分割一次 Set fso = CreateObject("Scripting.FileSystemObject") Set oSrcDoc = ActiveDocument Set oRange = oSrcDoc.Content nTotalPages = ActiveDocument.Content.Information(wdNumberOfPagesInDocument) oRange.Collapse wdCollapseStart oRange.Select For nIndex = 1 To nTotalPages Step nSteps Set oNewDoc = Documents.Add If nIndex + nSteps > nTotalPages Then nBound = nTotalPages Else nBound = nIndex + nSteps - 1 End If For nSubIndex = nIndex To nBound oSrcDoc.Activate oSrcDoc.Bookmarks("\page").Range.Copy oSrcDoc.Windows(1).Activate Application.Browser.Target = wdBrowsePage Application.Browser.Next oNewDoc.Activate oNewDoc.Windows(1).Selection.Paste Next nSubIndex strSrcName = oSrcDoc.FullName strNewName = fso.BuildPath(fso.GetParentFolderName(strSrcName), _ fso.GetBaseName(strSrcName) & "_" & (nIndex \ nSteps + 1) & "." & fso.GetExtensionName(strSrcName)) oNewDoc.SaveAs strNewName oNewDoc.Close False Next nIndex Set oNewDoc = Nothing Set oRange = Nothing Set oSrcDoc = Nothing Set fso = Nothing MsgBox "结束！" End Sub

4. 快捷键 F5 运行，直到出现“完成”表示结束。
