问题描述:

He began taking flying lessons at the age of 15.同义句转换
同义句转换 He began____ _____flying lessons when he was 15years old.

to take 考查的是begin to do=begin doing 初中阶段可以替换。更高级是有差别的,有时候不能互换的。例如:当和realize,know等搭配,只能用begin to know,begin to realize 不能用doing结构。

He began_to___ _take____flying lessons when he was 15years old.他 在15岁时开始上飞行课程
一般情况下 begin to do sth =begin doing sth.
