不必说更不必说 用英文怎么说啊

不必说...更不必说... 是一起用的吗?不过一起用汉语也不通顺呀,你是不是表达”我工作都可能作不完，更别说去买菜了”这个意思？
这样可以用let alone 连接或者not to mention
I can't even finish my job, let alone bought the food.
let alone bought the food 是虚拟时态． not to mention 后经常接名词

如果是分开的意思
不必说 needless to say
更不必说 let alone/not to mention

不必说更不必说Does not need to say not to mention
