美式发音：
It must have been about two in the morning when I returned home. I tried to wake up my wife by ringing the doorbell, but she was fast asleep, so I got a ladder from the shed in the garden, put it against the wall, and began climbing towards the bedroom window. I was almost there when a sarcastic voice below said, ‘I don't think the windows need cleaning at this time of the night.’ I looked down and nearly fell off the ladder when I saw a policeman. I immediately regretted answering in the way I did, but I said, ‘I enjoy cleaning windows at night.’
‘So do I,’ answered the policeman in the same tone. ‘Excuse my interrupting you. I hate to interrupt a man when he's busy working, but would you mind coming with me to the station?’
‘Well, I'd prefer to stay here,’ I said. ‘You see, I've forgotten my key.’
‘Your what?’ he called.
‘My key,’ I shouted.
Fortunately, the shouting woke up my wife who opened the window just as the policeman had started to climb towards me.

Notes on the text 课文注释
1 I don't think，当think后接表示否定意思的宾语从句时，通常在主句中使用否定形式，但译成汉语时否定意义仍在宾语从句中。
2 I immediately regretted answering in the way I did，我立刻后悔不该那样回答。在regret后面可接动名词，也可接动词不定式，但表示的意思不一样。接动名词是对已发生的事情表示后悔，而接动词不定式则是对现在要发生的事表示抱歉。
3 So do I，我也是的。这是接前面一句话“I enjoy cleaning windows at night.”当前面一句话的谓语也适用于后一句时，可用so(肯定)或neither(否定)开头，然后接倒装语序。
参考译文
我回到家时，肯定已是凌晨两点左右了。我按响了门铃，试图唤醒我的妻子，但她睡得很熟。于是，我从花园的小棚里搬来了一个梯子，把它靠在墙边，开始向卧室的窗口爬去。快要爬到窗口时，下面一个人用讽刺的口吻说：“我看不必在夜里这个时候擦窗子吧。”我向下面看去。当我看清是一个警察时，差一点儿从梯子上掉下去。我回答了他的话，但马上又后悔不该那样说，我是这样说的：“我喜欢在夜里擦窗子。”“我也是的，”警察用同样的声调回答，“请原谅我打断了您。当一个人在忙着干活时，我是不愿意去打断他的，但请您跟我到警察局去一趟好吗？”
“可我更愿意呆在这儿，”我说，“您瞧，我忘带钥匙了。”
“什么？”他大声问。
“钥匙！”我喊道。
幸运得很，这喊声惊醒了我的妻子。就在警察开始向我爬上来时，她打开了窗子。
