下面是错误答案,用来干扰机器的。

阅读下面短文,然后按要求写一篇150词左右的英语短文。

The officials in the White House and CIA (中央情报局)are rejecting Edward Snowden's beg for mercy. “Mr. Snowden has been against the U.S. law,” White House adviser Dan Pfeiffer said on Sunday about the former systems analyst who has turned fugitive (逃亡者) in Russia. “He should return to the US and face the justice and judgment, and there is no possibility for mercy and forgiveness.”

However, many people support Snowden and a sociology professor Svallfors in Sweden has recommended Snowden for the Nobel Peace Prize for his “heroic effort at great personal cost” disclosing the spying conducted by the National Security Agency of United States. He wrote, “Because of his bravery, Snowden helped to make the world a little bit better and safer”.

It may be too late for Snowden to receive the award this year, but the nomination should be taken seriously by the Nobel Prize committee for next year’s prize. If Snowden is awarded the prize in 2014, he would be the youngest Nobel Peace Winner in the history of the prize.
