C、
A、Watch Sb. do Sth.
Davoid doing 避免做某事

1 选D warned 句子的意思是：好学生是渴望学习的，不会被警告缺席太多。question是怀疑。询问的意思 ask是问的意思，persuade是劝告的意思。
2 选B rise的过去式。前边是sat表示了时态。
3 选D avoid后边的动词用ing形式，被认出，应该是被动，不用完成时，因此选D。

希望能帮高您。。。望采纳

1.A
and后面的分句是--- sb about sth这样一个结构的被动语态形式.能用在这一结构中的只有A、B两项；C项是warn sb of sth；D项是persuade sb into doing sth.ask sb about sth是一般的询问或请求；question sb about sth是正式质询,正式质疑.
句意：一个好学生是渴望学习的,因此不必因为他的缺课而进行过多的质疑/指责.
2.A
watch是感官动词,后面接的宾语补足语用动词原形,不用to do或动词的过去式,因此可以排除B、C.the sun和rise是主动关系,而且rise是不及物动词,不用于被动语态,因此可以排除D.
3.D
avoid doing sth是固定搭配,排除B、C.recognize并不先于谓语动词wore而发生,因此不用doing的完成式,因此可以排除A.
不明白的再问哟!请记得采纳,多谢!
