I. Prepare materials: space map, Moon map, and "" image. (It is best to use image processing software to remove background information from lunar and satellite maps .)
2. Insert materials: run PowerPoint 2003, create a blank slide, and run the format-background command to insert a star image as the background.Then execute the "Insert-image-from file" command to insert "moon map" and "satellite map" in sequence to adjust the large proportion and position.
3. Create an animation effect:Select "satellite chart" with the left mouse click to execute the "Slide Show-Custom Animation" command, expand the "Custom Animation" task pane, and click the drop-down button on the right of "add animation, select "action path-other action path" from the drop-down list and select "circular extension" from the "basic" type. Then, use the mouse to adjust the path position and size through six control points. Pull it into an elliptical shape and adjust it to a proper position.
4. Set the animation:In the "Custom Animation" pane, double-click the "circular extension animation" you just created, open the "circular extension" settings panel, and click "timing" with the left mouse button ", select the "start" type as "before", the speed as "slow (3 seconds)", and the repeated values as "only to the end of the slide ". (See figure 1) in this way, Chang'e will be able to automatically bypass the monthly flight again and again.
5. Draw a running track line:Use the "elliptical" tool in the "custom image" to draw an elliptical image, adjust its size and position, and make it overlap with the "circular expansion animation" path, then, set "fill color" to "no fill color", and set your favorite color and width for the line. Finally, right-click the "elliptical image" and execute the "stacked order-move down a layer" command to make the "satellite" bypass its orbit.
6. Surround processing:Copy and paste the "lunar map" to make it exactly the same as the "lunar map" just inserted. Right-click the pasted "lunar map" and execute the "Display 'image' toolbar" command. Open the "image" toolbar and select the "crop" command, crop the copied "moon map" from the bottom up to the appropriate size (see figure 2), so that the "satellite" produces the effect of bypassing the back of the Moon Ball.
7. After the animation is completed, execute "Slide Show-watch show", and our "Chang'e" will also be able to bypass the moon!
