Question

one year and a half 后应该是接单数形式吧?
比如one year and a half has passed.不是one and a half years 是one year and a half

Answer 1

one and a half ＋复数名词,谓语用复数还是单数要看接的是什么名词,如,One and a half years is a long time for me.一年半的时间对我来说是很长的.［这个句子谓语用单数是因为one and a half years表示的是一个整体时间,即time,是不可数名词］ 又如,One and a half dollars is a little money.1.5美圆并不是很多钱.［钱money是不可数名词］
但在下面这个句中就要用复数了,One and a half apples are for you.这一个半苹果是你的.［因为apple是可数名词,一个半就是复数了,因此谓语要用are］
