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 Sams money was paid back in this way. The last note said: I am 100 per cent honest now!
为何with a note whichsaid:后面用冒号而不需要逗号？
比如I said, “Let’s go shopping.” 这句就用逗号不需要冒号。
some more money中 some more 的词性？
50 per cent a thief中50 per cent是什么词性？为何不放在a的后面？
