1,One person could play a little bit of a song in his or her instrument.
改in？为什么？
2，
This is the time for rest and relaxation and for celebration as well as .
as well as 改为as well？
能改为too之类的吗？
为什么
1.用什么乐器，应该使用with2. as well as 改为as well。因为这里as well 表示“也”，常置于句尾，换成too不太通顺。too通常置于一个完整的句子后面，说明与前面一句的情况一致。This is the time for rest and relaxation；it is for celebration, too. This is the timenot onlyfor rest and relaxation but alsofor celebration.
