    Although being famous might sound like a dream come taste, today's stars, feeling like zoo animals, face pressures that few of us can imagine. They are at the center of much of the world's attention. Paparazzi(狗仔队)camp outside their homes, cameras ready. Tabloids(小报)publish thrilling stories about their personal lives. Just imagine not being able to do anything without being photographed or interrupted for a signature.

    According to the psychologists, celebrities(名人)worry constantly about their public appearance. Eventually, they start to lose track of who they really are, seeing themselves the way their fans imagine them, not as the people they were before everyone knew their names. Over little, they feel separated and alone.

    The phenomenon of tracking celebrities has been around for ages. In the 4th century B C., painters followed Alexander the Great into battle, hoping to picture his victories for his admirers. When Charles Dickens visited America in the 19th century, his sold-out readings attracted thousands of fans, leading him to complain about his lack of privacy. Tabloids of the 1920s and 1930s ran articles ghoul filth-slats in much the same way that modern tabloids and websites do.

    Being a public figure today, however, is a lot more difficult than it used to be. Superstars cannot move about without worrying about photographers with modem cameras. When they say something silly or do something ridiculous, there is always the Internet to spread the news in minutes and keep their "story" alive forever.

    If fame is so troublesome. Why aren't all celebrities running away from it'? The answer is there are still ways to deal with it. Some stars stay calm by surrounding themselves with trusted friends and family or by escaping to remote places away from big cities. They focus not on how famous they are but on what they love to do or whatever made theme famous in the first place. With these effective approaches, some celebrities relieve the stress and remain popular with fans. Consequently, though being famous is driving some stars crazy, some wise ones enjoy what reputation brings them.

The way of Chinese people's life has been changed through the China's" New Four Great Inventions". What are" New Four Great Inventions"? They are High-speed rail, Shared bikes, Online shopping and Alipay.

What did the China's" New Four Great Inventions" bring to us?

High-speed rail—Modern transportation makes everybody neighbor. The invention of the high-speed railway makes it easy to thousands of miles a day. Today China's rail transit technology is the best, the China's daily average of 4, 000 trains, sending about 4. 6 million passengers.

Shared bikes—Short walks become more convenient and faster, and carbon emissions are reduced, which is friendly to the environment. You can download the APP about shared bikes, pay some money, and then you can use bicycles everywhere in the street. The Chinese shared bicycle programs have been becoming more and more popular.

Online shopping—Don't need to go out to find the needs for living. Online shopping, as the name implies, is to pay money online. Purchases(购买物) can be sent home. China has 751 million Internet users, 724 million mobile phone users; total transactions on November 11 and December 12 hit a record high every year. Online shopping lets Chinese Internet users enjoy" shopping carnival" every day.

Alipay—A software which can replace cash payments. With intelligence phones' popularization, Alipay has become an indispensable (不可或缺的) APP. Through scanning the " QR code", Alipay wants to realize the ambition of " replacing cash payments" gradually. On 11th November 2018, both the mobile payment account and the transaction reached 213. 5 billion.

There is no doubt that China has already used its own power of" New Four Great Inventions" to become the great powerful technological country, showing the power of China once again.

Robotic Exoskeletons

Thanks to robotic exoskeletons, victims of spinal cord (脊髓) injury have a new reason to hope. Robotic exoskeletons, consisting of metal legs, motors, batteries, wiring, a controller and a set of strips work together like the user's bones, muscles and nerves-outside the body. Fastened into an exoskeleton and supported by sticks, users can direct the machinery to take them where they want to go.

In addition to partly restoring mobility, robotic exoskeletons offer the significant mental and physical health benefits of standing up and moving. Just being able to get up from a wheelchair gives patients a more natural, positive view of the world. It also helps relieve pressure on patients' skin and reduces the danger of pressure sores. Standing upright strengthens a disabled person's muscles and bones, improves heart health，and reduces certain other health complications (并发症). And it may actually result in partial nerve repair, something that can only happen when a patient is able to move.

As promising as this technology is, however, it is no simple cure-all for paralysis(瘫痪) or its complications. The motion is not accurate compared with natural walking, and exoskeletons are not easy to use, especially on surfaces that are not smooth. They are very expensive, costing about US$100000. Health insurance plans and government programs may not cover the cost of buying one.

Nevertheless, robotic exoskeletons, and access to them, will continue to improve. As with much modem technology, robotic exoskeletons will likely become more capable and easy to use, even as their cost goes down. Governments and insurers may increasingly see that the health benefits of these walking machines outweigh the costs, making it easier to fund them. Perhaps the day will come when nearly everyone paralyzed by spinal cord injury will be able to "walk" again.
