Question

—Your sister nearly devoted all her spare time ________ her study during the three years.
—That's right, or she ________ (take) first place in her school in the College Entrance Examination.

Answer 1

to；wouldn't have taken　

第一空根據時間狀語用一般過去時，devote...to...“致力于，奉獻于……”，第二空表示與過去事實相反的虛擬語氣，應用would/wouldn't have done。
