有问题的英语怎么说的

上周有个客人问我，怎么用英语表达“有问题的”，我就给他推荐了几种常用的说法。比如说：
1. "There is an issue with..." 2. "This has a problem..." 3. "There's something wrong with..." 4. "There is a concern about..." 5. "There's a difficulty with..."
每种说法都有它的用途，具体情况看你想怎么表达。比如，“There is an issue with the product”通常是指产品有问题；“There's something wrong with the system”则是指系统出了问题。总之，客人挺满意的，我觉得这样表达比较地道。

Problematic English.
有问题的地方怎么说：

• There's an issue here.
• This doesn't seem right.
• This part is problematic.
• I have concerns about this.
• This needs to be addressed.
  项目时间数字：例如，我在2022年3月的项目中遇到了一个“这个部分有问题”（This part is problematic），具体是在项目执行的第45天。
