我们知道to practice English with 是后置定语,但这里后置定语为什么要用不定式而不用动名词来担任.
比如.It is said that there will be 3000 schools teaching Chinese in 2050.
这里的动名词却又不能换成不定式
这是什么道理

1.doing作后置定语,相当于定语从句,doing的执行者是前面的先行词a partner;
如果是practising,就是partner是practise的执行者.
2.作定语的不定式很多与被修饰词在逻辑上是动宾关系.
I want to get something to read during the vacation.
She usually has a lot of meeting to attend in the evenings.
注：如果不定式是不及物动词,后面加介词.
There is nothing to worry about.

这要看动词跟主语之间的关系，这里很明显就是表主动。 而不定式更多的是作句子成分。

it is said that 据说 后面是宾语从句

所以你的理解....
