我给自己起了个英文名用英语怎么说

"I gave myself an English name" 可以用 "I chose an English name for myself" 或 "I named myself in English" 来表达。

这个短语的来源是因为有些人喜欢用英文名字来给自己取名字，这样在国际交往或使用英语时会更方便。

例句：

"I gave myself an English name because it sounds more professional in international business meetings." (我给自己起了个英文名，因为在国际商务会议中会听起来更专业。)
"I named myself in English because it makes it easier for my English-speaking friends to pronounce." (我用英文给自己起名字是因为这样我的英语朋友发音会更简单。)
