Mary is very young , but can't ride the bicycle 如何将这句化为同义句?速度求解!本人很急的!那个but是没有的

Mary is too young to ride the bicycle.

Although Mary is very young, she can't ride the bicycle.

Mary is too young to ride the bicycle .用的是too .to句型,意思是太...而不能.

你好，同义句是：

Mary is too young to ride the bicycle.
或者：Mary is so young that she can't ride the bicycle.

意思是：玛丽太小了不能骑自行车。
