我们在这里看到有些时候，我们应该用现在分词，有时要用过去分词。请看以下的句子：
We are naturally very much excited。
在这里，我们一定要用excited，绝对不能用
＊We are naturally very exciting。
下一句
Although dancing is interesting；
在这里，我们必须用interesting，而不能用interested。也就是说，我们不能说
＊Although dancing is interested。
（７）
We probably all believe that we should love others and forgive those who do bad things to us。 Unfortunately it is often hard for us to practice what we believe in。 For example； if someone really hurts us badly； we just do not know what we should do。 Should we take some kind of action to hurt the person who hurt us； or should we forgive him？
The truth is that we may still seek justice。 It is right if we want a criminal to go to jail for his crime。 Yet； we should never have hatred in our hearts。
