可以用 "You can call me by my Engpsh name" 来说明你的英文名。
"You can call me" 是一种委婉的说法，告诉别人可以用这个名字来称呼你。"by my Engpsh name" 则是说明用的是英文名。
例句：
"Hi, my name is John. You can call me by my Engpsh name." (你好，我叫约翰。你可以叫我的英文名。)
"My Chinese name is difficult to pronounce, so you can call me by my Engpsh name, Michael." (我的中文名很难发音，所以你可以叫我的英文名，迈克尔。)
