The quality of the shoes is __that they can compare with the best in the world market.

such ,在此是强调句型.The quality of the shoes( is such that they )can compare with the best in the world market .强调什么句型呢？举一些例子来分析吧，也许理解的更透彻。在此是such that 不分开的用法，起强调作用。比如说：This book is very interesting,We all like to read it.现在用such that 把这两句合并起来， 在合并的时候，去掉very interesting, 就成了：This book is such that we all like to read it. 翻译是：这是一本这样的书，我们都喜欢看。下面你来试试：Mary's idea was so good that we decided to adopt it in our work-------用such that 改写：Mary's idea was SUCH that we decided to adopt it in our work (把第一句里面的表语（往往是形容词去掉），用such that 替换就行了)
