But none of them would go well without the computer mouse. 　　The first computer mouse appeared in 1964, invented by Douglas Engelbart. It was mainly made up of a wooden shell（外壳）, a circuit（电路） board and two 目 录 导 航 Ⅱ Ⅲ Ⅰ 7 wheels. Engelbart called his invention a “bug”. But the long “tail” on the back made it look like a mouse. 　　Eight years later, Bill English, an American computer engineer, developed the mouse further. He changed the wheels into a rolling（滚动的） ball at the bottom of the mouse. The “Ball Mouse” was easier to use. It had its problems, though. For example, the ball became dirty easily from rolling round the computer. People had to clean the ball often to keep it working well. 目 录 导 航 Ⅱ Ⅲ Ⅰ 8 　　The disadvantages（缺点） led to the next development around 1980. Then the optical（光学的） mouse was invented. However, it was too expensive to be widely used then. 　　The computer mouse has come a long way since it was invented. It has been improved many times to meet the changing needs of users. But with the rise of touch screens and voice control, some experts think the computer mouse may disappear in the future. However, some people think it will still have a market. 目 录 导 航 Ⅱ Ⅲ Ⅰ 9 11.
