翻譯幾個(gè)英文句子：我只給杰克打過(guò)一兩次電話；我聽到一只小鳥正在樹上唱歌（過(guò)去進(jìn)行時(shí)）

I have just called jack for one or two times and I heard a bird was singing on the tree.

i only called jake twice
i heard a bird was singing in a tree

I just gave Jack one or two times on the phone; I heard a bird singing in the tree

這是兩個(gè)句子？
第一個(gè)句子用過(guò)去進(jìn)行時(shí)不合適。
1，I was making a phone with Jack once or twice.（過(guò)去進(jìn)行時(shí)）I just made a phone with Jack once or twice.(一般過(guò)去時(shí) 更合適)
2，I was hearing the sing of a bird on the tree.(過(guò)去進(jìn)行時(shí))
