一共有十处错误，每句话不超过两处。

Answer 1

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。

供参考

Answer 2

play--played

have  been  done  现在完成时  play为过去分词played

which--that

news引导同位语从句 连词应该用that

came--coming

performance 和come up为主动关系

hand--hands

两只手  所以复数

him-me

该短文主语是我

go--went

该短文为过去时态

proud+of

be proud of   对……自豪 固定词组

but--and

连词  翻译就可以

up--to

这个空不知道对不对

只能找出这么多了，按惯例是不是该有个拼写错误？好几年不做了，语法和短语都不太会了
