What is NP movement? Illustrate it with examples.
【正确答案】：NP movement involves the movement of a noun phrase. NP-movement occurs when, for example, a sentence changes from the active voice to the passive voice:
(A) The man beat the child.
(B) The child was beaten by the man.
B is the result of the movement of the noun phrases "the man" and "the child" from their original positions in (A) to new positions. That is, "the man" is postponed to the right and "the child" is preposed to the left. Not all instances of NP-movement, however, are related to changing a sentence from the active voice to the passive voice. For example:
(C) It seems they are quite fit for the job.
(D) They seem quite fit for the job.
These sentences are identical in meaning, but different in their superficial syntactic representations.
