【探究归纳】
receive和accept的辨析
(1)receive意为“接受,收到”,与主语的主观意愿无关,侧重于行为本身,不涉及收到者是否同意,是“ 客观上 ”的收到。
(2) accept意为“接受;承认”,它表示由主语的主观意愿决定,强调经过主语的考虑而接受,是“ 主观上 ”的接受。

【探究归纳】
(1)prevent为及物动词,意为“阻止;阻碍”。常用结构:prevent sb. (from) doing sth. 意为“阻止某人做某事”。
(2)stop...from doing sth. 与prevent...from doing sth. 意思相同,在主动语态中from可省略,但是被动语态中不能省略。
(3)keep...from doing sth. 意为“阻止……做某事”,无论是在主动语态还是被动语态中from都不能省略。
(4)protect...from...意为“保护……不受……侵袭”,from后接能带来伤害或损害之物。
