想象一下(Imagine)，您以壮观的倒计时开始您的 PowerPoint 演示文稿。创建倒计时是在演讲培训或研讨会会议开始时显示倒计时计时器的一种有效方式，倒计时可用于您希望在演示结束时向观众提供的测验。倒计时计时器是一种设计元素，用于对特定事件进行倒计时。
如何在PowerPoint中创建 倒数计时器(Countdown Timer)
打开PowerPoint。
如果您的幻灯片版式(Slide Layout)是标题幻灯片(Title slide)或任何其他幻灯片，请将其更改为空白幻灯片(Blank slide)。
现在，我们将格式化背景。为此，请单击“设计(Design)”选项卡，然后单击“自定义(Customize)”组中的“设置背景格式(Format Background)”按钮。
格式背景(Format Background) 窗格(Pane)将出现在右侧。
在“格式背景”窗格(Format Background Pane)中，您可以在其中看到“颜色(Color)”，然后选择一种颜色(Color)。
我们将转到“主页”选项卡上的“形状”，然后从“(Home)绘图”(Drawing )组的“形状(Shape)”列表框中选择一个形状。
将形状(Shape)绘制到幻灯片中。这个形状将是外部矩形。
我们希望形状看起来独特而富有艺术感。
点击形状；形状格式(Shape Format)选项卡将出现在菜单栏上。
单击形状格式(Shape Format)选项卡
在“形状格式(Shape Format)”选项卡上，我们将格式化形状。
要更改形状的颜色，请单击形状样式组中的(Shape Styles)形状填充(Shape Fill)按钮并选择颜色(Color)。
我们希望形状的(Shape)轮廓(Outline)具有不同的颜色和厚度。
要在格式选项卡上的(Format)形状样式(Shape Styles)组中执行此操作，请单击形状轮廓(Shape Outline)按钮。
在下拉列表中，选择一种颜色(Color)，然后为形状选择所需的重量。(Weigh)
现在我们要添加一些形状效果(Shape Effect)。
在下拉列表中，选择您想要的任何形状效果。(Shape Effects)在本教程中，我们选择一种反射效果(Reflection Effects)。
然后我们将再次单击形状效果(Shape Effects)为形状添加光晕。
在下拉列表中，将光标悬停在发光效果(Glow Effect)上，然后从列表中选择发光效果(Glow Effect)。
我们将为幻灯片上的形状添加另一个矩形。
在“格式(Format)”选项卡的“插入形状(Insert Shapes)”组中，从列表框中选择矩形形状并将其绘制在幻灯片上的形状内。这种形状将被称为内矩形。
我们将为形状添加一些动画。
单击外部矩形。
在动画(Animation)选项卡上，单击动画组中动画(Animation)列表框中的动画(Animation)。
从列表框中选择动画后，单击“效果选项(Effect Options)”按钮。
效果选项(Effect Options)按钮是一项功能，可让您将动画效果应用于形状。
在“效果选项(Effect Options)”按钮的下拉列表中，选择一种效果。
在高级动画(Advanced Animation)组中，单击动画窗格(Animation Pane)按钮。
右侧将出现一个动画窗格窗口。(Animation Pane)
确保选中的是内部矩形。
在Animation Pane上，右键单击显示的内部矩形。
在下拉列表中，单击“上一个之后的开始(Start after Previous)”或您想要的任何选项。
单击(Click)内部矩形，然后单击“格式(Format)”选项卡。
在“形状样式”(Shape Styles)组中，单击“形状轮廓(Shape Outline)”按钮。
然后单击无大纲(No Outline)。
现在我们想用一些独特的效果来填充内部矩形形状。
单击形状填充(Shape Fill)按钮。
在下拉列表中，将光标悬停在渐变(Gradient )上，然后单击更多渐变(More Gradient)。
格式形状(Format Shape) 窗格(Pane)将出现在窗口的右侧。
在填充和线条(Fill and line)部分，单击渐变(Gradient)。
渐变设置(Gradient Settings)将出现在格式形状( Format Shape) 窗格(Pane)下方。
在类型(Type)部分中，选择径向(Radial )或您喜欢的任何类型。
在方向(Direction)部分中，选择您喜欢的方向。
通过单击栏上的渐变色标为(Gradient Stops)渐变(Gradient Stop)色标添加颜色，并为每个色标选择一种颜色。
您将看到来自渐变(Gradient Stop)色标的颜色添加到内部矩形。
然后转到动画(Animation )选项卡并从动画(Animation )组中选择一个动画效果。(Animation Effect)
单击效果选项(Effect Options)按钮并从列表中选择一个选项，以添加到内部矩形。
在“动画窗格(Animation Pane)”窗口中，您可以右键单击任何矩形。
在下拉列表中，您可以选择单击(start on click)开始、从上一个(start with previous)开始和在上一个之后开始(start after previous)。
如果单击Effect Options或Timing，将出现一个对话框。
在对话框中，您可以更改Effect Option或Timing的设置。
然后，单击确定(Ok)。
现在我们要将数字放入形状中。
单击文本(Text)组中的插入(Insert)选项卡，单击文本框(Text Box)按钮。
在幻灯片上绘制文本框(Text Box)，在文本框中输入数字并将其放在矩形内。
单击(Click)带有数字的文本框并为其添加动画。
如果要为数字添加持续时间，请单击“动画(Animation )”选项卡上“时间(Timing )”组中的“持续时间(Duration)”列表框
请(Please)复制带有数字的文本框，将其粘贴到幻灯片上，更改其中的数字，并将其放在另一个数字上。
如果要播放或停止倒计时功能，请单击动画窗格上的(Animation Pane)播放(Play)或停止(Stop )按钮。
