问:

如何用英文表示它难道是飞行员吗如何用英文表示 难道我是飞行员吗?

答:
Here are two possible ways you can say it in English:
1."Am I a pilot by any chance?" 
This is a casual and colloquial way to ask the question. "By any chance" implies you doubt that you are actually a pilot but are posing the possibility.
2. "Is it possible that I am a pilot?" 
This is a slightly more formal and direct way to ask, using "Is it possible that" to indicate you are questioning whether the possibility exists that you are a pilot. 
我能否说一下别的用法:
1. "Could I be a pilot by any chance?" 同样是非正式用法。使用"Could I be"表示您在质疑您是否可能是一名飞行员。
2. "Might I be a pilot?" 使用"might"表示存在的可能性。这较正式些。
3. "Am I possibly a pilot?" 使用"possibly"表明您正在质疑您是否有可能是一名飞行员。
总的来说,英文中有很多表示"可能性"和"猜测"的方式,以上只提供了几个相对生动的例子。希望如此解释能满足您的要求。如有需要,欢迎再提问。
