I don't believe that _ little children can finishe this task in _a short time so such的区别.
第一个空填such,such是形容词,后面接名词,本题中即children.
第二个空也填such,
so是副词,后面加形容词.
但本题中little children,中心词是children,little跟such两个形容词一起修饰children.
such a short time 与such little children用法类似.

such, such

已给的答案是对的，解释得也很好，我就是想提醒一下提问者：so常做副词用，such常做形容词、代词用。而且，此句不是“so...that" "such...that"的句型。
