Answer:
Gliders, like other aeroplanes, fly by using ailerons, rudders, and elevators. Gliders are equipped with flaps to control fall speeds by boosting lift and producing drag. Many modern gliders also have airbrakes or spoilers, which obstruct airflow across the wing, raising drag and lowering lift.
"I finished my research paper two days early."
A good way to determine active vs passive is to ask who performed the action. Did the subject perform the action, or was the action performed "by" the subject?
The subject performs the action in this sentence:
I = [subject]
finished = [action]
my research paper = [thing on which the action was performed]
In the other examples, the subject has an action performed on it.
My research paper = [subject]
was finished/is being finished = [action]
two days early = [time frame information, not really important for the discussion here]
At this point, you have no indication as to who will finish the paper, do you? No. You assume that the paper will be completed "by me," but it could just as easily be completed "by my friend."
If you can add "by [person/thing]" to a sentence, it's passive voice. If you can't, it's not. Clearly, you would never say "I finished my research paper by me."
Answer:
why are we here? Why do we exist?
Explanation:
So are these just really good questions?
The Italian sonnet was mostly used by Petrarch, and it has a specific structure. It contains 14 lines, separated into one octave (a stanza of 8 lines), and one sestet (a stanza of 6 lines).
When it comes to the relation between the structure and the theme, this means that the octave introduces the idea of love within the sonnet. The poet talks about his beloved and gives us an insight into his feelings. On the other hand, the sestet analyzes his own emotions and explains in further detail why he is so infatuated with the woman (in Petrarch's case, he always wrote about Laura).
