What depressed her was that although she kept waving her hand, nobody seemed _______ her new watch.
A．noticing
B．to have been noticed
C．to have noticed
D．having noticed
答案
C
题目分析：句意：让她感到压抑的是，虽然她不停的在挥手，没有人似乎注意到她的新手表。Seem后面搭配不定式的不同形式，seem to do“似乎将要做”，seem to be doing似乎正在做…seem to have done似乎已经做了…，所以选C。
