这里用so 因为修饰的名词前面有个little是后面的progress 是名词
下面是对Such…that 和so …that 用法的分析 后面有不用 such而用so的几种情况的说明及例句
such…that作“如此…以致”解,连接一个表示结果的状语从句.与so…that
意思相同,但用法不同.
如：so…that这一结构中,so后边可加形容词或副词,
而such后边要用名词（这个名词前面可以带形容词,也可以不带）.因此,
such…that的句型结构可分以下三种：
1) such＋a(an)＋adj.＋单数可数名词＋that…clause
He is such a clever boy that everybody likes him.
他非常聪明,大家都非常喜欢他.
He was such an honest man that he was praised by the teacher.
他非常诚实,因而受到了老师的表扬.
2)such＋adj.＋复数可数名词＋that…clause
They are such interesting novels that I want to read them once again.
这些小说非常有趣,我想再读一遍.
3)such＋adj.＋不可数名词＋that…clause
He has made such great progress that the teachers are pleased with him.
他进步得很快,老师们对他感到很满意.
注意：如果such后边的名词前由many、much、few、little等词所修饰的话,则不用 such而用so.
例如：
He had so many falls that he was black and blue all over.
他摔了很多跤,以致于全身上下青一块,紫一块的.
He had so little education that he was unfit for this job.
他所受教育很少,不适合做这个工作.
There were so many people in the street watching the fire that firefighters could not get close to
the building.
街上有那么多人观看大火,以致于消防队员无法接近大楼.
