The Stevenson family was having dinner.The family ate without talking for severalminutes,then Tom said,"Daddy,do you know how wars begin?"
史蒂芬森一家人正在吃晚餐,好几分钟过去,他们一句话都没说.接着Tom问道：“爸,你知道战争是怎样开始的吗?”
Mr.Stevenson thought for a moment,then he said,"Yes,I think so.I'll give you an example.We'll take two countries,Britain and America.If Britain fought with America..."
史蒂芬森先生想了一会儿,然后他说：“是的,我想是这样的.给你举个例子吧.比如美国和英国,如果英国打了美国的话.”
Mrs.Stevenson laughed."That's crazy," she said to her husband."Britain and America have been friends for over two hundred years.They'll never fight."
史蒂芬森太太笑了.“那是不可能的”,她对她的丈夫说.“英国和美国已经结盟两百年了,它们才不打呢.”
"Yes,I know that," Mr.Stevenson said."I was only using them as an example."
“是的,我知道”史蒂芬森先生说,“我只是用它们来举个例子罢了.”
"But they're not a good example," Mrs.Stevenson said."France and Germany are a better example."
“但是这不是个好例子啊,”史蒂芬森太太说,“法国和德国这个例子会更好”.
"Britain and America are the best example," Mr.Stevenson replied."They are friends now but they were enemies in the past.They fought a war!"
“英国和美国才是最好的例子”,史蒂芬森先生回答道,“它们现在是盟友,但是过去也是敌对的,它们打过仗啊.”
"But that was a long time ago," Mrs.Stevenson said."You should use more modern examples."
“但是那也是很久以前的事了”,史蒂芬森太太说,“你应该用更现代的例子嘛”.
"And you should let me answer my son's question," Mr.Stevenson said angrily.
史蒂芬森先生生气地说：“你至少让我回答下我儿子的问题啊.”
"Not when you give him wrong answers," Mrs.Stevenson said.
“但是你现在给他的答案是错误的,所以才不让你回答”,史蒂芬森太太说.
"I am not giving him wrong answers!" Mr.Stevenson shouted."I am giving him perfectly good answers."
“我没给他错误的答案啊!”史蒂芬森先生喊道,“我给他的答案绝对正确”
"Don't shout at me!" Mrs.Stevenson cried." I'm not one of your stupid friends."
“别朝我喊!”史蒂芬森太太叫道,“我才不是你那些蠢朋友中的一员”.
"My friends aren't stupid!" Mr.Stevenson stood up and walked angrily out of the room.
“我的朋友才不蠢!”史蒂芬森先生站了起来,十分愤怒,走出了这个房间.
"Now I'll answer your question," Mrs.Stevenson said to her son.
“现在我来回答你的问题”,史蒂芬森太太对她的儿子说.
"It's all right,Mom," he said."You and Dad already have."
“不用了,妈”,他说“你和爸爸已经说得很明白了”.
翻译文章并回答问题：
why did Mr.and Mrs.Stevenson argue with each other?
When being asked "how the war begins" by their son.Mr.Stevenson took America and Britain as example,but his wife thought France and German would be better,then they began to argue which one is the BETTER example to demonstrate how the war begins,but they didn't known that they themselves had made a perfect example.
当被他们的儿子问及“战争怎么开始”时,史蒂芬森先生用了美国和英国的例子,但是他的太太觉得法国和德国的例子会更好,然后他们就为了争哪个更好吵了起来,但是他们不知道他们本身已经是相当好的例子了.
