Question

When he was a boy, he used to go there and watched _______.

A. repairing bicycles
B. to repair bicycles
C. bicycles being repaired
D. bicycles to be repaired

Answer 1

答案C
此题考查非谓语动词作宾语补足语的用法。 watch+O+OC，其宾补可用不带to的不定式、v?ing分词、v?ed 分词充当。非谓语动词的选择依据其与宾语之间的逻辑关系，bicycles 与 repair之间是被动关系，故排除答案A、B，而watch后跟复合宾语时，不可使用不定式作宾补，所以排除D。故答案为C。
