I can see the bottom-right quadrant clearly. It shows the /S/ sound and explains that to produce this sound, "Your tongue goes behind your teeth and teeth go together." The diagram illustrates this with a side profile of a person's mouth, showing the tongue positioned behind the upper front teeth with the teeth slightly closed (but not biting the tongue), which is characteristic of the English /S/ sound.
Now I have examined all four quadrants and understand how each sound is produced. Let me summarize the solution.
The image is teaching how to produce four specific English sounds by showing the correct tongue placement for each:
1.
/L/ sound: The tip of the tongue goes on the roof of the mouth (hard palate).
2.
/R/ sound: The tip of the tongue does NOT go on the roof of the mouth; it's positioned in the middle of the mouth without touching the roof.
3.
/TH/ sound: The tip of the tongue goes in between the upper and lower front teeth.
4.
/S/ sound: The tongue goes behind the upper front teeth with the teeth slightly closed together (but not biting the tongue).
This diagram provides a clear visual guide for learners to understand the articulation of these common English consonant sounds by showing the precise positioning of the tongue relative to other parts of the mouth.
