从一种植物中分离得到一种生物碱无根藤碱(cassyfiline)。在测定分子中的酚羟基位置时，曾用甲基化反应使生成N-甲基无根藤碱(N-Methylcassyfiline)。其¹H-NMR谱中出现两个芳香氢质子峰，δ7.59(1H、S、11-H)，δ6.80(1H、S、8-H)。如果将N-甲基无根藤碱混2%NaOD的重水(D₂O)溶液，于封闭管内在135～140℃加热15小时，而¹H-NMR中的δ6.80峰消失。请推断酚羟基所在的位置，并简述其理由：

  

在窗体上利用菜单编辑器设计一个主菜单项“菜单控制”(Name属性值为mnuMenu)，然后为其设计两个子菜单项“增加菜单”(Name属性值为mnuAdD)和“减少菜单”(Name属性值为mnuDel)，另外设置一个标题为空的菜单项<控件数组)，其Name属性值为mnuDyn，Index值为0，Visible属性值为False；然后编写以下程序来实现增加和减少菜单项的功能，完成程序。 Dim Inxld As Integer Private Sub mnuAdd_Click() Dim mnuc As String mnuc=InputBox("input caption") InxId；InxId+1 【 】mnuDyn(InxID) mnuDyn(InxlD)，Calption=mnuc mauDyn(InxID).Visible=True End Sub Private SubmnuDel_Click() Dim i As Integer If【 】Then MsgBox "菜单项已全部被删除" Else Unload mnuDyn(InxID) InxId=InxId-1 End If End Sub

听力原文： Born Cassius Clay in Louisville, Kentucky, in 1942, Muhammad Ali retired from boxing in 1980. As an amateur, he won 100 of 108 fights. Later, as a professional boxer, Ali was trained by Angelo Dundee, who pushed him on to face champion boxer Sonny Liston in 1964; in this exciting match, Liston was unable to continue the fight after the sixth round.
