阅读下面的材料，在空白处填入适当的内容（1个单词）或括号内单词的正确形式。

Modern inventions have sped up people’s lives amazingly. Motor cars cover a hundred miles in 【小题1】(little) than an hour, aircraft cross the world within a day, and computers operate at lightning speed. Indeed, this love of speed【小题2】(seem) never ending.

All this saves time, 【小题3】at a price. When we lose or gain half a day in speeding across the world in an airplane, our bodies tell us so. We get the uncomfortable feeling 【小题4】(know) as jet lag: our bodies feel that they have been left behind in another time zone. Again, spending too long on computers results in 【小题5】(pain) wrists and fingers.

What do we do with the time we have saved? Certainly not relax. In today’s fast-paced life, we find【小题6】 difficult to sit and do nothing or even just one thing at a time. Perhaps the days are long gone 【小题7】we might listen quietly to a story on the radio, letting 【小题8】(imagine) take us into another world.

There was a time when some people’s lives 【小题9】(go) on at a much gentler pace, and in a familiar pattern. We might envy a lifestyle like this. Yet before we do so, we must think of the hard tasks our ancestors faced: they farmed with bare hands, often lived close to hunger, and had to make 【小题10】(tool) from wood and stone.
