be afraid to do sth ,be afraid of doing sth的区别
a.be afraid to do sth
b.be afraid of doing sth
1.be afraid to do 主要指按照经验或常识不敢去做某事或没有勇气去做某事.如:
The little boy was afraid to go out at night.这个小男孩晚上不敢出去.
注:在现代英语中,也可以用be afraid of doing 结构来表示上述意思.如:
He was afraid to tell[of telling]his wife.他不敢告诉他妻子.
2.be afraid of doing 主要表示担心会发生某事(是一种无意行为),此时不能用be afraid to do 结构.如:

请再体会下列句子:
The girl was afraid to speak English before so many people because she was afraid of making mistakes.这个女孩不敢在那么多人面前说英语,因为她怕出错.
She was afraid to swim because she was afraid of drowning.
她不敢游泳,因为她担心会被淹死.
