问题描述：
It was such afunny show that people cloudn't help laughing again and again.
为什么那个空填 laughing?还有另外的选项（A.laugh B.to laugh C.正确 D to laughing）还有句子的意思很模糊,
答
It was such a funny show that people cloudn't help laughing again and again.
表演太搞笑了以至于人们都忍不住笑了又笑.
such.that 太...以至于...
can't/couldn't help doing sth..禁不住做某事
所以是laughing.
