Engelsk linguistik

Jeg sidder midt i en uge-eksamen og er ved at kløjs over nogle spørgsmål.

Nr. 1:
Is constituent 2 a PP (preposition phrase) or an IP (inflectional phrase)?
The second and conclusive experiment had yet [₂ to be attempted]

Derudover har jeg yderst svært ved følgende problem:

Question 3:
Give the tree structures of the following examples:

a. The brakes cannot have been checked for a long time

b. Do you know when they were last checked?

c. Last week, they really seemed to be fine.

Derudover:

Discuss both the position and the form of the finite verb in each of the finite clauses in 3a-c.
Identify all instances of wh-movement, of DP-movement and of head movement found in any of the examples, and give at least one argument for why this movement should be assumed to have taken place.

Håber nogen derude kan give en hjælpende hånd.
