A.to train to speak b. to train speaking c.training speaking d.train to speak

B

B
it是形式主语,to引导真正的主语
train sb. doing sth.吧

选B,练习it is to和have difficult doing

A

Difficult to do something
and you have to use to do something after him here

选B,
it是形式主语,to不定式引导真正的主语,原句应该这么表达:
To train him speaking English is difficult。
可为了避免头重脚轻,所以才用it引导一个主语从句的。

另外,本题还考察了train sb. doing sth (训练/教某人做什么)和be difficult to do sth(做什么事有困难)两个短语的用法
