[subject] + [verb] + 得 + [adjective]
[subject] + [verb] + 得 + 不 + [adjective]
[subject] + [verb] + [object] + [verb] + 得 + [adjective]
得 after a verb brings in a comment on how the action goes – how fast, how well, how early. The verb comes first, then 得, then the description, usually 很 plus an adjective.
The part after 得 is a degree complement – a complement is a word or phrase after the verb that says how the action turned out. 得 is read de here, the same as 的 and 地, but the three are different words.
A bare adjective after 得 sounds like half of a comparison – 他跑得快,我跑得慢. A plain statement takes 很, 非常 or another degree word.
To say something isn't done well, 不 goes after 得, in front of the adjective. 不 before the verb would deny the action itself.
The question puts 吗 at the end, or asks 怎么样 in the adjective's place.
Nothing can stand between the verb and 得, so an object has to go before it. Say the verb twice – once with the object, once with 得 – or put the object first and drop the first verb.
