英语翻译1.愚人节是非常特殊的节日,在这一天,你可以同朋友开玩笑却不会受到惩罚.（定从）2.他每当读这个故事时,总会被感动的流泪.3.他感到非常失望与无助,伤心的离开了教室.4.如果他们不能兑现他们的诺言又怎么办呢?5.夜幕降临时分,人群开始散开了.

这几道题我刚巧前几天做过,都是原题的正确答案.
1,April Fool’s Day is a very special day,on which you can play tricks on your friends without being punished.第一题考的是定语从句,后面的短语是修饰前面名词 a specail day的
2.He can not read the story without being moved to tears 考察的是双重否定等于肯定
3.Feeling very disappointed and helpless ,he left the classroom sadly 前面的一部分统统作为修饰部分,修饰后半个句子
4.What if they fail to keep their promise 考察短语what if的应用
5,The crowd started to break up when the night fell.人群要用crowd ,散开,分散break up,开始.start to do.fell是fall的过去式
