你的句型是錯(cuò)的,應(yīng)該是：
I was having a good/happy/great time with you.
= I was enjoying myself with you .
= I was having fun with you
根據(jù)漢語(yǔ)意思,用一般過(guò)去時(shí)更好,即
I had a good time / happy / great time with you .
= I enjoyed myself with you .
=I had fun with you .請(qǐng)問(wèn)為什么是was +doing 的形式呢過(guò)去進(jìn)行時(shí)呀，它的結(jié)構(gòu)是was +DOING感覺(jué)沒(méi)有必要用過(guò)去進(jìn)行時(shí)吧,如果是過(guò)去式呢,怎么說(shuō)所以我前面說(shuō)到用一般過(guò)去時(shí)更好呀。即

I had a good time / happy / great time with you .
= I enjoyed myself with you .
=I had fun with you .
