Computers, for example, have provided some with the fort of working from home while at the same time throwing others out of work as their jobs are automated. In the future changes are likely to be even much greater as science reaches out to shape life itself. New organisms (有機(jī)體) are already being engineered. New genetically modified crops promise benefits from higher yields and less use of harmful chemicals.But once again we cannot be sure that science will only change our lives for the better. The possibility remains that some modern Frankenstein may carelessly or deliberately let loose a new and 106 Appendix Idangerous form of life. However, we should have sufficient faith in the good sense of the public tobelieve that we could prevent this from happening.

For what many people find most striking about him is the contrast between the strength of his mind and the weakness of his body. For for many years Hawking has suffered from an illness that has left him unable to move and to speak normally.Born in England in 1942, Hawking had a normal childhood, and it was not until he was a student at university that his illness started to affect him. Hospital tests showed he was suffering from a disease that weakens control over the muscles. The disease gets worse with time and there is no known cure. But Hawking did not lose heart. As he says, although there was a cloud hanging over my future, I found, to my surprise, that I was enjoying life more than before. I began to make progress with my research, and I got engaged to a girl called Jane Wilde. That engagement changed my life. It gave me something to live for.Hawking started research at Cambridge and went on to hold the same post that another great scientist, Newton, once held. Over the years his condition has worsened, but even when he finally lost the ability to speak, he managed to get round the problem. He now uses a puter that enables him to select words which are then turned into speech. The only trouble, the English scientist says, is that it gives me an American accent! 102 Appendix IPart II Text AText Organ
