一定要说出为什么！！！

Answer 1

Play, often (D. seen) as an activity for younger children, is still important in the social development of teenagers.
Play, (which has often been/was often) seen as an activity for younger children, is still important in the social development of teenagers.

Answer 2

D.seen
玩耍，往往被视为年轻儿童的一种活动，在青少年的社会发展中,却仍然是很重要的。

被视为,是被动含义, AB不对.

而不定式,表示将来意义,或表达目的.

这里并不有这层意思,不能用不定式.

Answer 3

D.seen
过去分词表被动，作状语

Answer 4

D

Answer 5

D
看样子像是初三或者高一的题
play……is ……，说明"is"是谓语，中间那句用逗号隔开的就是定语，修饰play，see sth as sth是“把……看作……”的意思，由于游戏是被看作儿童们的活动，所以用被动，即play is seen as an activity for children.作定语，所以去掉is
