How to change a double-line title to a single line?

A professor is going to have a class on domestic situation and policy. Please ask Xiaolin to prepare a concise courseware for him. During the production process, Kobayashi found that the first-level title of the professor's textbook was particularly long, and the font would be too small if it was displayed in one line, so he adopted the mode of double-line display in the middle of the slide. But in this case, when the display title needs to be adjusted to the top of the page, the space occupied by two lines is too large, and it needs to be displayed in a single line instead. After some thinking and exploration, it was finally solved. The specific methods are as follows: Step 1: Making Double-line Titles In order to achieve the purpose of being beautiful and easy to modify, Kobayashi did not use large-scale image processing software such as PhotoShop, but used the "WordArt" function in Powerpoint to make titles. Click the Insert WordArt button in the Drawing toolbar, select the appropriate style, enter the first half of the title, and set the font. If you are not satisfied with the WordArt style after confirmation, you can use the tools on the WordArt toolbar to make adjustments until you are satisfied. Then copy a completed WordArt below it, double-click it and enter the other half of the title. If the number of words in the two parts is different, it is necessary to adjust the width of the wordart in the lower part to make it consistent with the first part (Figure 1). Figure 1 Step 2: Make a single-line title. Make a single-line title in the same way, input the text of the whole title, appropriately reduce the height of the wordart and put it at the top of the slide (Figure 2). Figure 2 Step 3: Make two wordart characters in the middle of the animation effect selection page, right-click to execute custom animation in the right-click menu, select Add Effect → Enter → Zoom in in the task pane on the right, and add an emerging effect. Before selecting in the start item, select the action path from Add Effect → diagonally upward to the right, and click Add Effect in the task pane on the right. Keep the two wordart in the selected state, and add the zoom-in/zoom-out effect again, so that the reduced size is almost the same as the top wordart. Select "before" in the starting item, then add the exit → disappearance effect to the two wordart, and select "after" in the starting item. Finally, select the whole line of wordart at the top of the slide, add the effect of "appearing", and select "after" in the "Start" item. At this point, this slide is completed. Play it once, the effect is that when playing this slide, the eye-catching double-line title will appear first. After clicking, the double-line title will be moved and reduced to the top position respectively and merged into one line. Please refer to the sample document in the attachment for the demonstration effect. This presentation uses "Chinese Super Black" font. Please download and install this font before displaying it, otherwise it will affect the viewing effect.
