　　5. Why are people misled by their own eyes?
　　Ⅱ. 1. Read the three questions in the short passage and discuss them in groups of four.
　　2. Report your answers to the whole class.
　　Sample answers:
　　1. We often use one or two of the five senses more than the others when we need to. For example, in the darkness, the sense of hearing and sense of touch become more sensitive because we can’t see anything. When we listen to our favorite music, we still close our eyes and just listen with our ears. When we read a very interesting book, we’ll lose ourselves in it, and hardly hear anything around us. When we eat something, we not only taste or smell it, but look at it as well.
　　2. I think that when hearing English, the sense of sight and the sense of hearing help me a lot. I usually listen to the tape before I read. While I’m listening to the tape, I’ll look at the text. And I often read the English text aloud. The combination of these two senses best helps me remember what I have learnt.
　　3. Beethoven He began to lose his hearing in 1801 and was partly deaf by 1819.In 1824, when
　　he was completely deaf, Beethoven completed his most famous Symphony, the Ninth Symphony.
