Happily I received notice of my admission.

take notice of 和take the notice of 有什么区别?

take notice of: 注意...
比如：When constructing a sentence in English, one should take notice of the appropriate tenses at all times. 用英语造句，无论何时都要注意采用相应的时态。

take the notice of: 领取（得到）...的通知
比如：Please take the notice of payment from your teacher's office and pay the tuition in full at the accounting department. 请到你老师的办公室领取你的付款通知，然后到财会部缴纳全部学费。

你给的句子语法错误啊！！！

应该是I still have not receive my 11 cartoons of my slippers

意思是：我还没有收到我的11双卡通拖鞋

第二句应该是：I will claim my slippers and please tell the people in Khasa to be very careful.

意思是：我会拿回我的拖鞋，不过请你告诉Khasa人要小心。

我很高兴的收到录取通知书
admission允许进入的意思，也就是录取

好高兴我收到了录取通知
