afraid/fear/frightened的区别是什么？贝贝今天跟大家分享一下。
I.afraid“害怕”是形容词，只能作表语，而不能作定语，后接of短语或不定式，构成be afraid of sb.和be afraid to do sth
① She is afraid of a snake.她害怕蛇。
② The little girl is afraid to go out at night.
afraid+that从句“恐怕”，是婉转拒绝别人的一种表达方式。 如：
① I'm afraid (that) I can't go to the party.My brother is sick.
恐怕我不能去参加聚会了。我弟弟病了。
II.fear“害怕”是动词，与be afraid往往通用，但不如它常用（特别是在口语中)。如：
①We fear no difficulty.我们不怕困难。
②He feared to speak his mind.他不敢说出自己的想法。
③Fearing that he would catch cold,I went out to see him.因为怕他会受凉，我走去看他。
Ⅲ.frightened adj“受惊吓的、害怕的”可做表语，也可作定语。如：
①She is too frightened to move.她太害怕了不能动弹。
②Afrightened girl is crying.一个受惊的女孩正在哭。
