It had been wrapped up in newspaper and it contained half the money he had lost, together with a note which said: 'A thief, yes, but only 50 per cent a thief!' Two months later, some more money was sent to Sam with another note: 'Only 25 per cent a thief now!' In time, all Sam's money was paid back in this way. The last note said: 'I am 100 per cent honest now!'

1. 为什么with a note which said: 后面用冒号而不用逗号？

   例如I said, “Let’s go shopping.” 这句就用逗号不用冒号。

2. some more money中 some more 的词性？

3. 50 per cent a thief中 50 per cent是什么词性？为什么不放在a的后面？
