I was only eight years old when the Second World War ended, but I can still remember something about the   36   celebrations in the small town where I lived on the day when the war in Europe ended. We had not   37   much from the war where, though, like most children of my age, I often saw   38   houses in the streets and the very big   39   lorries(卡车) passing through. But both at home and at school I had become   40   to the phrases “before the war” and “when the war is over”. “Before the war”, obviously,   41   had been better, though I was too young to understand why,   42   there had been no bombs then, and people had eaten things like ice cream and bananas, which I had  43   heard of. When the war was over we would go back to London, but this meant very  44   to me. I did not remember what London was like.

What I remember now  45   V-Day(victory day) was the afternoon and the evening. Some boys and girls were collecting   46  and building an enormous bonfire(篝火). We stood and watched them for a time, and then I went home and   47   myself in with my key and waited for my parents to come back from work.

It was May and still broad   48  when my mother arrived, and my father came in about an hour later. After dinner I said I wanted to   49   the bonfire, so when it got dark my father took me to the end of the street. The bonfire was very   50  , and somehow people had collected some old clothes to   51   “Hitler” with the moustache(胡子) they had put on top of it. Just as we arrived, they set light to it. The flames   52   soon. Everyone was cheering and shouting.

I stood beside my father until the   53   started to go down, not knowing what to say. He said nothing, either. He had   54   in the First World War and remembered everything he had experienced. At last he said, “Well, that’s it, son. Let’s hope that this time it really will be the   55   one.”
