Add two more columns, modifying an existing VBA code help.

Hi all.

I want some help, to modify this VBA code. I want to copy additional columns Z and AA, the even numbered rows, starting with Z8.
Thank you in advance.

Sub test()
    Dim ws As Worksheet, i As Long, x As Range
    Application.ScreenUpdating = False
    With Sheets("CONTROL")
    .Select
        For Each ws In Worksheets(Array(2, 3, 4, 5, 6, 7))
            If ws.Name <> Me.Name Then
                With ws.Range("b9").CurrentRegion
                    For i = 1 To .Rows.Count Step 2
                        If x Is Nothing Then
                            Set x = .Rows(i).EntireRow.Range("b1,g1:h1")
                        Else
                            Set x = Union(x, .Rows(i).EntireRow.Range("b1,g1:h1"))
                        End If
                    Next
                End With
                If Not x Is Nothing Then
                    .Range("b" & Rows.Count).End(xlUp)(2).Select
                    x.Copy
                    Me.Paste link:=True
                End If
                Set x = Nothing
            End If
        Next
        .[b3].Select
    End With
    With Application
        .CutCopyMode = False
        .ScreenUpdating = True
    End With
End Sub
