这道选择题为什么选C,不是A?
8.Professor Li _______ in doing his experiment for nearly ten years.
A. insisted B. piled C. persisted D. split
答
insist是坚持要做某事，persisted是坚持做了某事————个人感觉
答
insist坚持做一件事，搭配insist on
persist坚持反复做同一件事，搭配persist in
题中给了介词in，所以选C。
答
这个是固定搭配
persist in doing something
坚持做某事
Professor Li (persisted) in doing his experiment for nearly ten years.
李教授坚持实验近十年了.
insist坚持（某种观点）
pile up堆砌
split分裂
