同学你好~
这里要选一个副词，修饰动词dusted，careful是形容词，carefully是副词，所以选择carefully

形容词主要有以下用法：
1. 用作定语，修饰名词：This is a very interesting book. 这是一本很有趣的书。
2. 用作表语，用于系动词之后：This book is very interesting. 这本书很有趣。
3. 用作补语，修饰宾语：We found this book very interesting. 我们发现这本书很有趣。

副词修饰动词、形容词、其他副词或全句，表示时间、地点、程度、方式等概念。
He replied to my letter very quickly. 他立即答复了我的信。
very quickly修饰动词短语replied to my letter

(1) 时间副词：常见的有now, then, soon, ago, recently, lately, later, before, early, today, tomorrow, yesterday, tonight, suddenly, immediately, still, already, just等。

(2) 地点副词：常见的有here, there, up, down, away, nearby, home, ahead, abroad, indoors, overseas, upstairs, downstairs等。

(3) 方式副词：表示行为方式的副词大多以-ly结尾，常见的有quietly, heavily, warmly, carefully, happily, politely, angrily等。

(4) 频度副词：常见的有always, usually, often, frequently, constantly, occasionally, sometimes, seldom, hardly, rarely, never等。

5) 程度副词：常见的有fairly, pretty, rather, quite, very, much, too, greatly, almost, nearly, half, highly, deeply, partly, perfectly, really等。
