实际原因用英语怎么说

"Actual reason" 可以用英文表示为 "real reason" 或者 "true reason".
"Real" 和 "true" 都是形容词，意思是真实的、实在的、真正的、本质的。在这种情况下，"real reason" 和 "true reason" 都可以用来指真正的原因或本质原因，即使在外界看来可能有表面上的原因，但真正的原因是另外一个方面。
举个例子，如果一个人因为睡过头而迟到了，那么他可能会告诉别人是因为路上堵车了，但实际原因是因为他睡过头了。这时候，我们可以用 "real reason" 或者 "true reason" 来指代实际原因，即 "He was late because he overslept, not because of traffic as he told others. That's the real/true reason."
例句：
"I thought I didn't get the job because of my lack of experience, but it turns out the real reason was because the company was going through restructuring. That was the true reason I didn't get the job."
"She said she couldn't come to the party because she had a lot of work to do, but the real reason was because she didn't want to see her ex-boyfriend who was going to be there. That was the true reason she didn't come."
中文翻译：
"我以为我没有得到这份工作是因为我缺乏经验，但事实上真正的原因是因为公司正在进行重组。那就是我没有得到这份工作的真正原因。"
"她说她不能来参加聚会是因为她有很多工作要做，但实际原因是因为她不想见到她的前男友，他也会来参加聚会。那就是她不来的
