How should one invest a sum of money in inflation (通货膨胀)? Left in a bank it will hardly keep its value, however high the interest rate. Only a brave man, or a very rich one, dares to buy and sell on the Stock Market. Today it seems that one of the best ways to protect your savings, and even increase your wealth is to buy beautiful objects from the past. Here I am going to offer some advice on collecting antique clocks, which I personally consider are among the most interesting of antiques.
I sometimes wonder what a being from another planet might report back about our way of life. "The planet Earth is ruled by a mysterious creature that sits or stands in a room and makes a strange ticking sound. It has a face with twelve black marks and two hands. Men can do nothing without its permission, and it fastens its young round people's wrists so that everywhere men go they are still under its control. This creature is the real master of Earth and men are its slaves."
Whether or not we are slaves of time today depends on our culture and personality, but it is believed that many years ago kings kept special slaves to tell the time. Certain men were very clever at measuring the time according to the beating of their own hearts. They were made to stand in a fixed place and every hour or so would shout time. So it seems that the first clocks were human beings.
However, men quickly found more convenient and reliable ways of telling the time. They learned to use the shadows cast by the sun. They marked the hours on candles, used sand in hour- glasses, and invented water-clocks. Indeed, any serious student of antique should spend as much time as possible visiting palaces, stately homes and museums to see some of the finest examples of clocks from the past.
Antique clocks could be very expensive, but one of the joys of collecting clocks is that it is still possible to find quite cheap ones for your own home. After all, if you are going to be ruled by time, why not invest in an antique clock and perhaps make a future profit?
【小题1】According to the passage, collecting antique clocks ________.

Below is a selection from a popular science book.
If blood is red, why are veins（静脉） blue?
Actually, veins are not blue at all. They are more of a clear, yellowish color. Although blood looks red when it’s outside the body, when it’s sitting in the vein near the surface of the skin, it’s more of a dark reddish purple color. At the right depth, these blood-filled veins reflect less red light than the surrounding skin, making them look blue by comparison.
Which works harder, you heart or your brain?
That kind of depends on whether you’re busy thinking or busy exercising. Your heart works up to three times harder during exercise, and shifts enough blood over a lifetime to fill a supertanker. But in the long run, your brain probably tips it, because even when you’re sitting still your brain is using twice as much energy as your heart, and it takes four to five times as much blood to feed it.
Why do teeth fall out, and why don’t they grow back in grown-ups?
Baby (or “milk”) teeth do not last long; they fall out to make bigger room for bigger, stronger adult teeth later on. Adult teeth fall our when they become damaged, decayed and infected by bacteria. Once this second set of teeth has grown in, you’re done. When they’re gone, they are gone. This is because nature figures you’re set for life, and what controls regrowth of your teeth switches off.
Do old people shrink as they age?
Yes and no. Many people do get shorter as they age. But, when they do, it isn’t because they’re shrinking all over. They lose height as their spine（脊柱） becomes shorter and more curved due to disuse and the effect of gravity(重力). Many (but not all) men and women do lose height as they get older. Men lose and average of 3-4 cm in height as they age, while women may lose 5 cm or more. If you live to be 200 years old, would you keep shrinking till you were, like 60 cm tall, like a little boy again? No, because old people don’t really shrink! It is not that they are growing backwards ----- their legs, arms and backbones getting shorter. When they do get shorter, it’s because the spine has shortened a little. Or, more often, become more bent and curved.
Why does spinning make you dizzy（眩晕的）?
Because your brain gets confused between what you’re seeing and what you’re feeling. The brain senses that you’re spinning using special gravity-and-motion-sensing organs in your inner ear, which work together with your eyes to keep your vision balance stable. But when you suddenly stop spinning the system goes out of control, and your brain thinks you’removing while you’re not.
Where do feelings and emotions come from?
Mostly from an ancient part of the brain called the limbic system. All mammals have this brain area ----- from mice to dogs, cats, and humans. So all mammals feel basic emotions like fear, pain and pleasure. But since human feelings also involve other, newer bits of the brain, we feel more complex emotions than any other animal on this planet.
If exercise wears you out, how can it be good for you?
Because our bodies adapt to everything we do to them. And as far as your body is concerned, it’s “use it, or lose it”! It’s not that exercise makes you healthy, it’s more that a lack of exercise leaves your body weak and easily affected by disease

In business, there is a speed difference: It's the difference between how important a firms leaders say speed is to their competitive (竞争的) strategy（策略）and how fast the company actually moves. The difference is important regardless of industry and company size .Companies fearful of losing their competitive advantage spend much time and money looking for ways to pick up the speed.
In our study of 343 businesses, the companies that choose to go, go, go to try to gain an edge ended up with lower sales and operating incomes than those that paused at key moments to make sure they were on the right track, What’s more, the firms that “slowed down to speed up “improved their top and bottom lines, averaging 40% higher sales and 52% higher operating incomes over a three-year period.
How did they disobey the laws of business physics, taking more time than competitors yet performing better? They thought differently about what “slower” and “faster” mean. Firms sometimes fail to understand the difference between operation speed (moving quickly )and strategic speed (reducing the time it takes to deliver value ).Simply increasing the speed of production, for example ,may be one way to try to reduce the speed difference .But that often leads to reduced value over time, in the form of lower-quality products and services.
In our study, higher-performing companies with strategic speed always made changes when necessary. They became more open to ideas and discussion. They encouraged new ways of thinking. And they allowed time to look back and learn. By contrast (相比而言), performance suffered at firms that moved fast all the time, paid too much attention to improving efficiency, stuck to tested methods, didn’t develop team spirit among their employees, and had little time thinking about changes.
Strategic speed serves as a kind of leadership. Teams that regularly take time to get things right , rather than plough ahead full bore , are more successful in meeting their business goals . That kind of strategy must come from the top.
