5 . THE TIME MACHINE
It was at ten o'clock today that the first of all Time Machines began its career. I gave it a last check, and sat myself in the leather seat. I pushed the starting lever (操纵杆) on the main panel forwards an inch then immediately backwards again. Looking around, I saw my laboratory exactly as before. Had anything happened? I thought my mind had tricked me. Then I saw the clock. A moment before, it was a minute or so past ten; now it nearly half past three!
I drew a breath, gripped(紧握) the lever and pushed it forwards. The laboratory went hazy around me. My niece came in to fetch something, maybe her handkerchief, apparently without seeing me. It probably took her a minute, but to me she moved like a rocket! I pushed the lever further. Night came as if a lamp was being turned out, and in another moment came the day. Tomorrow night came, then skipped to day, again and again, faster and faster still.
It is hard to explain the strange and unpleasant feeling of time travelling. It felt like I was being driven fast on a winding road. As my pace grew faster, the walls of the laboratory fell away, and I was left in the open air. The sun and moon looked as if they were being thrown across the sky, but soon there was division between night and day. Around me I saw trees growing like puffs of smoke; they grew, spread, and died in moments. I saw huge buildings rise up, then disappear like in a dream. The whole surface of the earth was being changed, melting and flowing before my eyes. I calculated that I was being pushed through time at hundreds of years a minute.
I had a strong urge to look at the random things that were being flashed before my eyes! I had thought about the risk of stopping the Time Machine many times. So long as I travelled at maximum speed, it didn't matter. But if I stopped and the same space was being occupied by something else, we would be forced together and explode like a bomb! Like an impatient fool, I pulled the lever backwards hard. With a sudden jolt, the Time Machine was flipped on its side, and I was thrown through the air.
I was stunned for a moment, and then heard the sound of thunder. I was sitting in the rain in some mud next to the machine. “A fine welcome,” I said, “for a man who has travelled thousands of years to be here!”
(Adapted from the novel The Time Machine written by H.G.Wells, a novelist famous for the science fiction)

8 . “Demographics are our fate”, which suggests much of the future is determined by the very simple trend lines of populations. Of course, demographics can’t spot pandemics or other crises. But as shocking as they feel at the moment, such events are rare. One aspect of the future that demographics can’t help predict are technological discoveries. But even technological discoveries have a slower impact on the daily life than we sometimes perceive. Peter Thiel famously said in 2013, “We wanted flying cars. Instead, we got nothing but 140 characters.”
So what comes next? If you woke up 20 years from now in 2042, what would be different? Here are some ideas based on numbers that don’t require a crystal ball. About 70 percent of the world population is expected to live in urban areas by 2050, according to data from the United Nations. That means most cities are going to need more improvements. Roads, public transportation and waste management will need large-scale expansion and upgrades. The average person produces 4.9 pounds of waste a day, up from 3.66 pounds in 1980. But here’s a trend going in the other direction as a result of technology: Paper and paperboard declined from 87.7 million tons in 2000 to 67.4 million tons in 2018, according to the U.S. Environmental Protection Agency.
And we’ll be older. In the United States, we’re likely to live until 82.4 years old, compared with 79.1 years old today, the United Nations predicts. That’s a good thing for health care companies and others that satisfy the needs of older people. But living three extra years is going to be more expensive, which will have an influence on both working and saving.
Businesspersons, industry leaders and policymakers are already at work solving some of the problems that demographic data suggest are ahead of us. They are trying to figure out how to inspire farmers to sequester carbon and use green machines to reduce the energy consumption.
What about the metaverse? Or robots taking our jobs? Or AI taking over everything? Demographics can’t answer those questions. All of those things may happen, but life in 2042 may also look a lot like it does today maybe with the exception of those flying cars.

9 . Created from natural materials such as mulberry leaves and bamboo, the earliest umbrella in China was used to protect themselves from dangers. Sometime in 1st century BC, first paper umbrellas appeared and they very quickly found their way to the hands of wealthy females who by then accepted the sun-shade umbrella as a necessary part of their fashion accessory (配件) like animals’ skin and fur. Even though carefully produced and delicate umbrellas from paper and silk weighed only few hundred grams, they were capable of protecting their bearers from the rain because of the special process of applying oil on their cover.
Because of their shortage and high cost, umbrellas quickly became a symbol of power in China and surrounding Asian countries. To differentiate themselves from the rest of the population, Chinese royal members carried only red or yellow umbrellas, while the rest used blue ones. As the centuries went on, the cost of Chinese umbrellas went down, which enabled them to be used by general population and even males. Personal use was not the only application for umbrellas, and many creative designs were introduced even as early as 3rd century AD.
Surrounding countries adopted the umbrella into their tradition, often showing beautiful designs and artwork with great pride, especially by royal members in Korea, Burma and Siam. Travelers from the West soon carried Chinese umbrellas to continental Europe which was just exiting Dark Ages and was eager to adopt new fashion from distant lands. Umbrellas soon took over the female nobility (贵族) in Italy, France and England, where they managed to slowly evolve umbrellas into the general accessory that is used by everyone today.
Even though modern plastic umbrellas represent the majority of worldwide sales, traditional Chinese umbrellas are still respected by many. They are always in great demand. Fujian and Hunan Provinces are still making millions of them every year and the most respected Hangzhou-style umbrellas are now known for their quality and beauty.
