on fire; D.spring up

When spirited by the teacher, the discussion began to---- among the students.
A. sprang up; B. jump up; C.on fire; D. spring up
选择D,表示活跃的意思,begin to 后面是动词原形。
整句话的意思为受到老师的鼓励,同学们开始展开了活跃的讨论。

D 表示活跃起来了。
这句话是说收到老师的鼓舞,同学们之间的讨论活跃起来了!

D. spring up
began to spring up出现;涌现;萌芽
不定式,后面要跟原形.
当被老师鼓励, 讨论就在同学们之间出现了.
be on fire
adv. 着火;起火;在兴头上;非常激动
jump up跳起来;上投断层

答案:D
解释:begin to do sth. 表示“开始做某事”,to 后面接动词原形,所以排除AC。jump up 表示“跳起来”,与句意不符,答案D spring up 表示“涌现,出现”,是正确答案。
