now, there are many versions about where is the Amber Room.
our class had a discuss for should the Amber Room be returned?(1)
there are 80 percent of us think that the Amber Room should be returned. because it's a historical relics. if it cannot be returned, it shows this country（2） was weak in history. they cannot keep the Amber room safe(3), it's a national disgrace.
the rest 20 percent of us think that the Amber room should not be returned. because the Amber Room can be sell for lots of money and it also shows that this country(4) was really powerful.
in my opinion, the Amber Room should be returned. because it's a historical relics, it shows the changes of this country(5).
1, 所说的归还，是谁归还给谁? 这里最好解释清楚。
2，这里所说的 “这个国家” 是指那个国家，最好加上国家名称。
3，琥珀屋，不小而且很重。所以加上“小小的”感觉怪怪的，所以我没写上。要不要试试加上“重要的”？
4，同样2， 最好是写上国家名称。但是如果4跟2是一样的国家，就不需要了。
5，同4.
最后，基本上就是这样了。
如果你觉得我的那些建议是多余的，直接忽视就好。
因为那一段英文是照着你原文翻译的。
如果还有问题，请追问我。
