如果你想要表达"简单来说"这个意思，可以使用英语短语"in short"或者"in a nutshell"。
例句：
In short, the company is looking for someone with strong communication skills and experience in marketing.
In a nutshell, the project is about improving the efficiency of our supply chain.
注意："in short"和"in a nutshell"都是用来表示"简要地说"的意思，但是"in short"更多用在正式的场合，而"in a nutshell"更常用于非正式的场合。
