英语翻译一天,王先生发现自己5岁的儿子小明行为有些古怪.快到傍晚的时候,他一个人站在窗口向外挥手,口中似乎还念念有词.王

One day,Mr Wang found his 5-year-old son XiaoMing a littel weird.
When the night fell,the little boy was found to be at the window side,waving his hands while his mouth seemed murmuring.
Quietly,he draws behind the little boy,only to hear "Goodbye grandpa,goodbye grandpa..."
Looking out of the window,there was nobody there.In the following days,when time came,the boy would be at the window side,repeating the words which made Mr Wang thrilling.
Finally,Mr Wang found himself not able to stand it anymore.He called his son forward and asked,"XiaoMing,whom are you saying byebye these days?""It's grandpa",XiaoMing replied sincerely.Mr Wang was suddenly caught by a great horror and shiveried,"Whi..i..ch grandpa?"
"The grandpa sun",said the little boy still in excitement.
大致这样了,能力有限.
