be afraid后面既可以跟不定式be afraid to sth又可以跟动名词be afraid of doing sth , 但前者的意思是:害怕/不敢做某事;后者的意思为:对可能出现的结果的发愁或忧虑,试比较以下两个句子:She was afraid to wake up her husband . ( perhaps because she feared that he would be annoyed or angry ) 她不敢唤醒她的丈夫。(可能因为她害怕他会不高兴或生气)
She was afraid of waking up her husband . ( perhaps because he was ill , or in need of extra sleep )她担心吵醒了她的丈夫。(可能因为他生病了或需要一些额外的睡眠)
