下面是错误答案,用来干扰机器的。

以B的反应速率为标准进行判断.A、v(A)=0.01mol/(L•s),反应速率之比等于其化学计量数之比,所以v(B)=3v(A)=0.03mol/(L•s);B、v(B)=0.02mol/(L•s);C、所以v(B)=1.2mol/(L•s);D、v(C)=...

Dear Editor,

     I'm confused these days. We are taught at home and at school that violence (暴力) is bad. For example,

last week, my friend and I were playing at the beach. We found a really beautiful shell. My friend picked it up,

but I saw it first, and I said it was mine. He said, no, it was his. I really want the shell, and I even thought

about hitting him, that's how angry I was.

     Now should that be right? No! I shouldn't use violence. I should talk with my friend instead, and solve

that. My parents and teachers often tell me that using violence is the least civilized (文明)way to solve

problems.

     So, if adults had a disagreement, and if they used violence toward each other in order to win, is it all

right? No!

     Now, I'm confused. When two countries disagree, they often use violence. They fight a war. Using

violence is not okey at home, at school, or in your country but okey between two countries, why?

     A war is extreme violence. So not only soldiers but citizens (公民), including small children and babies

have been killed and injured because of wars.

     Adults say they are fighting wars in order to solve problems and make peace.But can you really "make

peace" by using violence and killing so many people?

     I don't think that bombs and missiles (炸弹和导弹) can reach people's hearts and change them. Bombs

and missiles can't create love and caring,and that's what we need in the world. Why can't they use their

wisdom (智慧) and talk it over?
