unreliable item

基本解釋

By W ALTER S. M OSSBERGThere's no other major item most of us own that is as confusing, unpredictable and unreliable as a personal computer.
對(duì)于大多數(shù)人來(lái)說(shuō)，所擁有的大宗商品沒(méi)有比個(gè)人電腦更令人困惑，更難以猜測(cè)，更不可靠的了。
Like having an incomplete list of all expenses, being unrealistic with the amounts you allocate to each item will make the budget unreliable and highly ineffective.
就像一個(gè)不完整的花銷(xiāo)清單，分配給每個(gè)項(xiàng)目的金額費(fèi)用是不現(xiàn)實(shí)的，那么這個(gè)預(yù)算是不可靠并且高度無(wú)效的。
