In the sentence:
 
Isabel Burnell wanted to impress her classmates with
the new doll's house.
 
It is a passive type of a sentence, meaning the
subject is indirect, with comma, or uses ‘by’ or im this case ‘with’. 
Here, the
verb used is past while in active sentence, the verb used is in present tense
and is direct in giving out information. If the sentence is changed into active
form of the sentence, it could be:
 
<span>Isabel Burnell’s new doll's house impressed her
classmates.</span>
