They often fly kites on Sunday a.m. 哪里错了

已知a>0,b<0,|b|>|a|,试把a,-a,b,-b,0五个数用“<”号连接起来

They often fly kites on Sunday a.m.应该改成They often fly kites at Sunday morning.

若a<b<0,则|a| > |b|,-a > -b.

They often fly kites on Sundy morning.

｜a｜＞｜b｜，-a＞-b

最后那个a.m啥意思？要出现时间才用这个，早上就直接说morning

am..- -不行
下面那个那句不行！about at两个介词不行！去掉about
最好还是they have had lunch at 11.00.
强调刚吃完的状态。
