单选题
If more students A
are thriving
in higher education, high schools must B
not only
help them earn good grades in demanding courses, but also C
step up their work
to guide them through the difficult process of D
choosing and applying to
colleges.
【正确答案】
A
【答案解析】解析：are thriving一are to thrive。句意：如果更多的学生想要在高等教育中蓬勃发展，高校不仅要帮助学生获得高分，更要加速指导学生克服选择和申请大学的困难。根据句意可知，“学生想要在高等教育中蓬勃发展”是if从句对将来情况的一种假设，目前尚未发生，故应该采用be to do的形式表示将来。
