Example 1 If the parallel lines $E F$ and $M N$ intersect with the intersecting lines $A B$ and $C D$ to form the figure shown in Figure 1, then the number of consecutive interior angles obtained is ( ).
(A) 4
(B) 8
(C) 12
(D) 16
The solution provided is (Figure 2), which decomposes the given figure into 8 basic "three-line eight-angle" shapes. Knowing that each basic shape has 2 consecutive interior angles, a total of 16 consecutive interior angles are obtained ${ }^{[1]}$.
