这是小学五年级的第二单元, 平移;请结合生活实际,生动活泼,有创意的表现---The following content is extracted from the image:
**Overall Title:** 平移 (Translation)
**Introductory Text:**
下面图形的运动都是平移。
(The movements of the shapes below are all translations.)
**Examples of Translation (Illustrative Images):**
1. **Image Description:** Three red flags with yellow stars (Chinese flags) are shown on poles, indicating a movement or translation.
2. **Image Description:** A filing cabinet with one drawer partially pulled out, illustrating the concept of translation.
3. **Image Description:** A cable car moving along a wire, demonstrating translation.

**Question Block 1:**
**Question Stem:**
请你画出小旗向左平移 4 格后得到的图形,并与同伴交流。你能回答笑笑的问题吗?
(Please draw the shape obtained by translating the small flag 4 squares to the left, and discuss with your partner. Can you answer Xiaoxiao's question?)
**Chart/Diagram (Original Flag):**
* **Type:** Grid with a geometric figure.
* **Main Elements:** A grid (approximately 10 cells wide by 8 cells high). A red rectangular flag shape is drawn within the grid.
* **Description of Flag:** The flag is located towards the bottom-right of the visible grid. It occupies 3 squares horizontally and 2 squares vertically. Its bottom-left corner is positioned such that there are 3 empty squares to its left on the bottom row, and 1 empty square below it on the rightmost column.
**Dialogue/Thought Bubble (Xiaoxiao):**
如 图,在小旗上找一个点向左平移 4 格,再从平移后的点开始,照原图画好……
(As shown in the figure, find a point on the small flag, translate it 4 squares to the left, and then start drawing the original figure from the translated point...)
**Dialogue/Thought Bubble (Taoqi):**
我移动后的结果怎么和淘气的 结果不一样?
(Why is the result after my translation different from Taoqi's result?)
**Chart/Diagram (Taoqi's Attempt - Shows incorrect translation):**
* **Type:** Grid with two geometric figures.
* **Main Elements:** A larger grid (approximately 13 cells wide by 8 cells high). Two red rectangular flag shapes are drawn.
* **Description of Flags:** The first flag (original) is in the bottom-center of the grid. It occupies 3 squares horizontally and 2 squares vertically. The second flag (Taoqi's translation) is positioned to the right of the first flag. Its bottom-left corner is 4 squares to the right of the first flag's bottom-left corner. This visually represents a translation 4 squares to the right, which contradicts the instruction of translating "向左平移 4 格" (4 squares to the left).

**Question Block 2:**
**Question Stem:**
请你画出右图中中小旗向上平移 4 格后得到的图形,并说一说。
(Please draw the shape obtained by translating the small flag in the right figure 4 squares upwards, and explain.)
**Chart/Diagram (Original Flag):**
* **Type:** Grid with a geometric figure.
* **Main Elements:** A grid (approximately 10 cells wide by 8 cells high). A red rectangular flag shape is drawn within the grid.
* **Description of Flag:** The flag is located towards the bottom-right of the visible grid. It occupies 3 squares horizontally and 2 squares vertically. Its bottom-left corner is positioned such that there are 3 empty squares to its left on the bottom row, and 1 empty square below it on the rightmost column. (This chart is identical in appearance to the first flag chart in Question Block 1).
**Hint/Note:**
注意,小旗平移后,大小和形状都不能改变!
(Note that after the flag is translated, its size and shape cannot change!)

**Question Block 3:**
**Question Stem:**
请在方格纸上画出小船先向左平移 5 格,再向上平移 5 格后的图形。
(Please draw the shape of the boat after translating it 5 squares to the left, and then 5 squares upwards, on the grid paper.)
**Chart/Diagram (Original Boat):**
* **Type:** Grid with a geometric figure.
* **Main Elements:** A large grid (approximately 17 cells wide by 12 cells high). A boat shape is drawn using lines on the grid.
* **Description of Boat Shape:**
* The boat is located at the bottom-right of the grid.
* The base of the boat is a horizontal line segment 4 units long, starting from the 3rd column from the right edge and the 2nd row from the bottom edge.
* From the left end of the base, a diagonal line goes up 2 units and right 1 unit.
* From the right end of the base, a diagonal line goes up 2 units and left 1 unit. These two diagonal lines meet, forming a triangular hull with a base of 4 units and a height of 2 units.
* From the top vertex of the triangular hull, a vertical mast extends upwards for 2 units.
* From the top of the mast, a horizontal line segment extends 2 units to the right, forming the top edge of a sail.
* From the bottom of the mast (where it meets the hull), a diagonal line extends up 2 units and right 2 units, connecting to the right end of the top sail edge, completing a triangular sail.
* All vertices of the boat shape are located at grid intersections.
