可别误以为 “姐弟恋” 是 “sister-younger brother love”，在英语里，sister 和 brother 指有血缘关系的亲属。有两个关键单词得先掌握：“cradle”，读音 /ˈkreɪdl/ ，意为 “摇篮”；“snatcher”，读音 /ˈsnætʃər/ ，是 “抢夺者” 的意思。“cradle snatcher” 字面理解就是抢夺还在摇篮里的，用来形容追求比自己年轻得多的异性的人，老少恋中年龄大的那一方都能用这个词。而 “cradle-snatcher love” 则特指姐弟恋、老妻少夫这种恋爱类型。例句：①The media was full of stories about their cradle-snatcher love, as he was ten years younger.
媒体上全是关于他俩姐弟恋的报道，因为男方小十岁。
老牛吃嫩草用英语怎么说？当年龄差距较大时，中文里我们常调侃 “老牛吃嫩草” ，英文表达用到 “rob”（抢夺）这个词，“Rob the cradle”，字面是 “抢劫摇篮”，引申义就是和年纪小很多的人交往，等同于中文的 “老牛吃嫩草、老少配”。例句：You're robbing the cradle! She's just out of college, and you're in your forties. 你这是在老牛吃嫩草！她刚大学毕业，你都四十多了。
异地恋用英语怎么说？“异地恋” 的正确英文说法是 “a long-distance relationship” 。情景对话：A: We've been in a long-distance relationship for nearly three years. It's so hard, especially when I'm sick. 我们异地恋快三年了。太难了，尤其是我生病的时候。B: I know it's tough. But long-distance relationships can also make your bond stronger if you manage it well. 我知道这不容易。不过要是处理得好，异地恋也能让你们感情更牢固。
网恋用英语怎么说？“网恋” 常用的英语表达是 “cyber love（romance）/online love affair ”，“cyber” 读音 ['saɪbə]，意为 “网络的” 。例句：Some people believe that cyber love is full of illusions. 有些人觉得网恋充满了幻想。
早恋用英语怎么说？直译的话，“早恋” 是 “fall in love at an early age” ，不过更精准的翻译是 “puppy love”例句：Schools often hold seminars to talk about puppy love, guiding students to focus on their studies. 学校经常举办研讨会讨论早恋问题，引导学生专注学习。
单相思用英语怎么说？①“one-sided love”，表示一方单方面投入感情的 “单相思”。例句：
I endured one-sided love for years, but finally decided to move on.
我经历了多年的单相思，最后决定放下。②“one-way love”，同样指单行的、没有回应的爱。例句：
His one-way love made him sad, but it also taught him a lot about relationships.
他的单恋让他难过，不过也让他对感情有了更多认识。③“carry a torch for (sb/sth).”，也是单恋某人的意思。例句：
She has been carrying a torch for her high school crush ever since graduation.
毕业后她就一直单恋着高中时暗恋的那个人。
