be afraid of sth.
害怕某事
固定搭配
根據主語把be動詞換掉
be afraid to do sth.真正的意思是“害怕做某事”,也就是主語對做某事內心感到恐懼；be afraid of doing sth.表示主語內心裡不情願做某事,也可以說是不希望發生某事,但自己不一定能避免它.
例如：
He was afraid to go out alone at night.(他害怕晚上獨自外出.暗含的意思是“他對於晚上獨自外出缺乏安全感”.)
He came late to school and was afraid of being scolded by the teacher.(他上學遲到了,害怕被老師吵.暗含的意思是“他不情願被老師吵”.)
用“不敢.”來辨別這兩個短語很能說明問題.
He is afraid of being beaten by his father.他怕被他爸打.（不是他敢不敢的問題,他是不情願.）
He is afraid to touch the snake.他不敢碰那條蛇.（他內心裡恐懼蛇.）
此外還有be worried about等片語。
