第十五题，为什么选A？

badly副词表修饰。修饰动词dress 这是被动语态

Bad vs. Badly
The word bad is an adjective used to modify nouns and pronouns.
Example: She was in a bad accident.
Adverbs often end in ly. The word badly is an adverb that answers how about the verb.
Example: She was hurt badly in the accident.
The confusion comes with four of the sense verbs: taste, look, smell, and feel.
When we use these verbs actively, we should follow them with adverbs. (Hear is always used actively.)
When we use these verbs descriptively, we should follow them with adjectives.
Examples:
I feel bad about having said that.
I am not feeling with fingers in the above example; I am describing my state of mind, so the adjective is used (no ly).
She feels badly since her fingers were burned.
She feels with her fingers here so the adverb (ly form) is used.

这里要填副词，只有badly才是

dressed是动词（v.)lively是副词（adv)，副词修饰动词，构成动副结构所以选a

副词修饰形容词，空白处需要填一个副词修饰dressed（它是在这里相当于形容词）

副词修饰动词
