Constant practice has such as effect on memory as to lead to skillful performance on the piano, to recitation of a poem, and even to reading and understanding these words.

这里的such as effect on memory as to lead..是啥用法?
能帮我分析下吗?感谢

你可能没看出来吧，它就是一个短语：as to就是做目的状语。汉语意思：为了。。

as to
prep.

=With regard to:
We are puzzled as to how it happened.

和……一样

状语 为了
