Complete the friends' dramatic text message exchange about a terrible new roommate.
My new roommate is a disaster! She _________________________ three plates this week!
And the worst part? She _________________________ my favorite coffee mug yesterday morning!
The correct answers are has broken and dropped.
has broken: We use the Present Perfect with unfinished time words like "this week," "this month," or "today" because the time period is still happening. She might break more plates!
dropped: We use the Past Simple with finished time words like "yesterday," "last night," or "in 2010."
Tip for Romance language speakers: Watch out! In Spanish, you might say "Ayer ha tirado mi taza" (Present Perfect), but in English, "yesterday" strictly requires the Past Simple.
