优质解答

1.I have been playing
have been doing sth 是现在完成进行时
（不是I have been played,这是我被耍了的意思好吗...-_-||）
2.the news that
that 作为连词
3.performance coming up
coming up 是后置定语
4.my hands
改成复数
（这我不太确定有没有那么容易...）
5.let me
句子的主语是我,me
6.I went up
go 的过去式动词 went
7.the end
那首曲子的结尾,应该要是the
8.proud of
固定用语proud + of
9.That was
is 的过去式 was
10.and I will
but 是转折介词,在这里和前后句子的含义有矛盾,因此用and替代.
