really与real的用法区别是词性不同、侧重点不同。real多用在形容词和副词前面表示强调，而really的位置则比较灵活，它通常可放在动词前和复合权谓语的第一个动词后面。

例句：They are not really my aunt and uncle.其实他们并不是我的姑姑和姑父。I can't believe I am really going to meet the princess.我不敢相信我真的要去见公主。In the movies guns kill people instantly, but it's not like that in real life .电影中，枪能使人在瞬间毙命，而实际情况并非如此。
