    Dentists always ask questions when it is impossible for you to answer. My dentist had just pulled out one of my teeth and had told me to rest for a while. I tried to say something, but my mouth was full of cotton wool. He knew I collected match boxes and asked me whether my collection was growing. He then asked me how my brother was and whether I liked my new job in London. In answer to these questions I either nodded or made strange noises. Meanwhile, my tongue was busy searching out the hole where the tooth had been. I suddenly felt very worried, but could not say anything. When the dentist at last removed the cotton wool from my mouth, I was able to tell him that he had pulled out the wrong tooth.

... when it is impossible for you to answer

    ·It 作形式主语，To answer is impossible for you.    去回答对你来说是不可能的

to rest = have a rest

In answer to    对 ... 问题的回答

for a while    一会儿，片刻

search out    搜寻

Meanwhile adv.    修饰整句话，所以直接放在句首后面加个 "," 修饰整个句子

be busy doing sth.    忙于做某事

at last    最后，终于
