Let's analyze the sentence "I have torn the papers last night" by labeling the components.
- Subject (S): "I"
- Verb (V): "have torn"
- Object (O): "the papers"
- Adverbial (A): "last night"
We can label the sentence like this:
I (S)
have torn (V)
the papers (O)
last night (A)
Now, putting brackets around each component:
[I] (S) [have torn] (V) [the papers] (O) [last night] (A)
So it looks like this:
[I] (S) [have torn] (V) [the papers] (O) [last night] (A)
(Note: The sentence also contains a temporal adverbial "last night," specifying when the action occurred.)
However, please note that grammatically the phrase "have torn" should not typically combine with "last night" because "have torn" suggests a present perfect tense, which usually doesn't pair with a specific past time reference like "last night." A more correct sentence might be, "I tore the papers last night."
