Explanation:

1. For $CH_3 - C(=O)-NH_2$, the presence of the amide - carbonyl ($-CONH_2$) group classifies it as an amide.
2. For $CH_3 - O - CH_3$, the general formula $R - O - R'$ (where $R = R'=CH_3$) indicates it is an ether.
3. For the compound with the structure where there is a carbon - carbon double bond adjacent to a carbon - oxygen double bond ($C = C - C=O$), it is an $\alpha,\beta$-unsaturated carbonyl compound.

Answer:

1. Amide
2. Ether
3. $\alpha,\beta$-unsaturated carbonyl compound
