when he was a boy,he used to go there and watch_______ A 、to repair bicycles B、bicycles to be repaired C、bicycles being repaired D、repairing bicycles 请问为什么要选C？

Answer 1

你好！
used
to
do
sth.为固定词组，意思是“过去常常做某事”
go
there与watch
＿是动词加名词的并列结构，being
repair
是bicycls
的后置定语，因而“bicycles
being
repair”是个名词，所以C为正确答案。
如有疑问，请追问。
