The popular TV program Readers has prompted more people in China to practice reading aloud in booths(亭) set up in big cities across the country．

    As the latest TV show to help people's love for literature recover, CCTV program Readers invites people from all walks of life to read aloud their favorite poems，essays and books，or even personal letters they wrote to their loved ones．Just as the weekly show has been well-received，its reading booths, equipped with professional recording devices and cameras，have become instant hits．

    A crowd of more than 200 people were pictured lining up outside the Shanghai Library at 11 a.m. on March 4 — the first day of the booth's opening to the public in Shanghai. The deadline for registrations was brought forward to 2 p.m. instead of the scheduled 5:30 p.m., as the number of waiting readers continued to grow. Some waited more than nine hours for a try-out in the booth, according to library management．

     “There is an old photo in the late 1970s capturing people lining up outside the Shanghai Library before it opens. If that was a spring of reading in Shanghai, now I think another spring has arrived again.” library manager Zhou Deming, told the Shanghai-based The Paper．

    The reading booth is the only one of its kind in the city of economic center at the moment, but more are expected to be put into use in the coming months, according to the library's website．

    The Readers program has also led to booths in other cities including Beijing, Hangzhou, Guangzhou and Xi'an to appeal to more people to read and share their life stories．

    With the recent boom of culture-themed TV shows such as Readers and Chinese Poetry Competition，some are optimistic that this will help the country love literature and reading again in general．

    Oh my God, the robots are taking over! We're doomed! Doomed! Now that I've gotten that out of my system, it's become clear that while we may or may not be doomed, the robots are taking over. The latest example is the government's new guidelines for self-driving cars.

    Tesla, Google and Uber are already testing driverless cars in cities across America. Uber chief executive Travis Kalanick is among those predicting that by 2021, self-driving cars will play a big part in urban settings.

    Nearly 40,000 people died last year in this nation in automobile-related accidents, and we believes driverless cars can save tens of thousands of lives annually.

    Makes sense. Robot drivers are less likely to get drunk, drive without a license, text while driving or feel agitated at the scene of a pileup. On the other hand, I wonder how these highly sensitive cars will react, with walkers constantly dashing into the street. Will they jam on the brakes every 10 seconds?

    But there's a bigger picture. Not only are robots replacing humans behind the wheel, but behind the work desk, in warehouses, senior homes, you name it. Robots aren't just taking over in the workplace.

    The question is, where can't a robot function better than a human? How about writing songs? A robot can go through every combination of notes in record time and come up with a pleasing melody. The lyrics might be a different story. Is a Grammy-winning song co-written by Hank Human and R-3071 in our future?

    Finally, it's only a matter of time until we have robot politicians and presidential candidates. Why not? They can be programmed to be experts in world and domestic affairs and come up with the best solutions without corruption and bad humors.

    Actually, it's too bad such technology isn't available in 2016. Pretty sure the robot would win in a landslide.

    One of the most exciting and interesting international cities to visit is London, England. Here is a look at four free things to do during a vacation to London.

    Visit the Trafalgar Square

    Built more than 200 years ago, Trafalgar Square is a popular gathering place for locals and travelers, too. The area is close to good shopping and dining opportunities, and there are usually some sorts of public events or celebrations going on there during most weekends.

    Wander Along the Thames

    Visitors wanting to sec some great architecture, attractions and views should spend an afternoon walking along the River Thames. The best place to start is at the world-famous London Bridge crossing over the river and you can walk all the way to Westminster Bridge a short distance away. Travelers doing this will find themselves passing by a great many historic buildings.

    Explore the Local Markets

    While purchasing items at any of the open markets in London is not necessarily free, walking through them to view the merchants（商人）, their products and the other shoppers is of great fun. Some of the popular open markets in London worth visiting include Spitafields Market, Portobello Road Market and Leadenhall Market.

     Visit the British Museum

    One of the top museums in the entire United Kingdom can be found in London, and it charges no admission（人场费）for entry. This museum is so highly regarded that it is not only popular with locals and tourists, it is also seen as a major and valuable scholarly resource.

    New Zealand's government is hoping to make the nation greener by planting 100 million trees each year, ensuring the electricity grid（电网） runs entirely from renewable energy, and spending more money on cycle ways and rail transport. The government's plan is to reduce its net greenhouse gas emissionto zero by the year 2050.

    New Zealand's prime minister Jacinda Ardern has set ambitious environmental policies to confronta warming planet. “We will absolutely focus on the challenge of climate change,” said Ardern. “That will include a zero carbon government policy. That will include an independent climate commission. That will include making sure that we have an all gases, all sectors emissions trading scheme,” she added. According to the Associated Press (AP), Arden said the goal of doubling the amount of trees the country plants each year is “absolutely achievable.”

    Not everybody is happy with the plans. Many farmers are worried they will be required to pay more if they are absorbed into an emissions trading plan. “There is concern that if this should happen, New Zealand will become less competitive with other food-producing nations.” said Katie Milne, the president of Federated Farmers.

    More than 80 percent of New Zealand's electricity already comes from renewable resources. The AP reported that Ardern wants to increase it to 100 percent by 2035, in part by investing more in solar, which currently takes up only 0.1 percent of the country's total renewable energy slice.

    Chinese scientists recently have produced two monkeys with the same gene, Zhong Zhong and Hua Hua, using the same technique that gave us Dolly the sheep. These monkeys are not actually the first primates(灵长类)to be cloned. Another one named Tetra was produced in the late 1990s by embryo(胚胎)splitting, the division of an early-stage embryo into two or four separate cells to make clones. By contrast, they were each made by replacing an egg cell nucleus(卵原子核)with DNA from a differentiated body cell. This Dolly method, known as somatic(躯体的) cell nuclear transfer(SCNT), can create more clones and allows researchers greater control over the edits they make to the DNA.

    Success came from adopting several new techniques. These included a new type of microscopy(显微术) to better view the cells during handling or using several materials that encourage cell reprogramming, which hadn't been tried before on primates. Still, the research process proved difficult, and many attempts by the team failed. Just two healthy baby monkeys born from more than 60 tested mothers. This leads to many researchers' pouring water on the idea that the team's results bring scientists closer to cloning humans. They thought this work is not a stepping stone to establishing methods for obtaining live born human clones. Instead, this clearly remains a very foolish thing to attempt, and it would be far too inefficient, far too unsafe, and it is also pointless.

    But the scientists involved emphasize that this is not their goal. There is now no barrier for cloning primate species, thus cloning humans is closer to reality. However, their research purpose is entirely for producing non-human primate models for human diseases; they absolutely have no intention, and society will not permit this work to be extended to humans. Despite limitations, they treat this breakthrough as a novel model system for scientists studying human biology and disease.

Once upon a time, science fiction was just a style among other styles. There were crime stories, there were horror stories, there was literary fiction, and there was science fiction. But today science themes dominate these other styles. It's difficult to think of much modern crime, horror or "serious" fiction that doesn't involve science.

And its not just books. With every second movie and computer game having a sci-fi element, science fiction seems to have controlled our entire entertainment culture. It's clear that if we want to define science fiction, we should relate it to the role that science plays in our lives.

Although some experts have claimed to be able to trace sci-fi back to ancient times, it is more reasonable to find it in initial form in the 19^th century, when industrial societies arose. One of the features that set industrial societies apart from other kinds was the increasing part that science played in everyday life. Factories with vast machines turned out huge quantities of goods, which were transported by trains, motor vehicles and ships all over the world. Cities were built on the back of technology, with electricity in homes and hospitals helping everyone to lead healthier, more convenient lives. All of these changes had great effects not only on people's real lives, but on their imaginative ones.

Writers began to describe these changing physical and mental landscapes, eventually giving science fiction a large and devoted fan base of especially young readers, who found that it spoke to their curiosity about the future that science would create.

But sci-fiction reflected fears about science more than it did hopes. These typical early science fiction novels might be a UK novel like H. G. Wells' The War of the worlds (1897). With great skill, Wells played upon the fears of technology by imagining Earth under threat by a civilization-that of men from Mars.

The science fiction of today expresses the impact of the computing revolution, robotics and our environmental challenges, while it is less concerned with "little green men from Mar" and other themes of past sci-fiction.

Given that science, technology and polities are always intertwined, contemporary science fiction often has a great deal to say about power. Many recent novels-like American Cory Doctorow's Little Brother (2008)-are concerned with government and security service "conspiracies (阴谋)" against the people, particularly as the revelations of whistleblowers like Edward Snowden sink in. This can give sci-fi writing a "skeptical (怀疑的)" feel.

This underlines one of the features that remains constant between the beginnings of the empire of science fiction and its state today.

As then, so now: We want to read about how fearful the future will be, not how it will be a paradise.
