网友的句子：Her husband is always been cheap with his money.

应为 Her husband's always been cheap with his money. （'s = has）

网友应该多动脑子，is been 还是 has been？

在美国英语中，cheap 有“吝啬的” 之意，但不常用，偶尔跟 with 搭配。例如：

The company is sometimes very cheap with the travel expenses.

其余两个说法都都可以。例如：

Don't be mean with fabric, otherwise curtains will end up looking skimpy.  

别这么吝啬布料，不然做出来的窗帘会显得特寒酸。

来自柯林斯例句

He has no friends, for he is mean about money. 

他没有朋友，因为他对钱很吝啬。
